Bruxism: The Hidden Emotional Causes of Teeth Grinding and Jaw Clenching

What Is Bruxism?

Bruxism is the medical term for grinding your teeth or clenching your jaw. It can happen while you are awake or asleep, and you may not even realize you are doing it.

Some people grind their teeth audibly during the night. Others clench their jaws without making much noise.

You might only discover the problem when you wake up with a headache, notice soreness around your jaw, or visit your dentist and learn that your teeth are showing signs of wear.

According to the National Institute of Dental and Craniofacial Research, bruxism can be associated with several factors, including stress, anxiety, mood, genetics, certain medications, and lifestyle factors.

When teeth grinding or jaw clenching becomes frequent or severe, it can contribute to several problems, including:

• Jaw pain, tightness, or muscle fatigue.

• Headaches, particularly around the temples.

• Tooth sensitivity.

• Worn, chipped, or damaged teeth.

• Discomfort around the face.

• Disrupted sleep or reduced sleep quality.

Not everyone who grinds their teeth develops these problems. However, persistent bruxism deserves attention, particularly if you experience pain or notice damage to your teeth.

A dentist can assess the physical effects and help you determine what treatment may be appropriate.

But there is another question I want you to consider.

What if, alongside addressing the physical symptoms, you also explored the stress and emotional experiences that might be contributing to your jaw tension?

This is where we begin looking at the relationship between your emotional life and your physical well-being.

1. Repressed Anger: When Life Feels Unfair

Let’s start with something many people find difficult to acknowledge: anger.

Not everyone expresses anger by shouting, arguing, or confronting other people.

Some people express it by becoming quieter.

They tell themselves to be patient. They convince themselves that there is no point in arguing. They accept situations they don’t agree with because they don’t want to upset anyone or make things worse.

They might even tell themselves, “I’m not an angry person.”

But being a kind person doesn’t mean you never experience anger.

And being good at controlling your reactions doesn’t necessarily mean you have resolved the feelings underneath them.

Think about your childhood for a moment.

Perhaps you grew up in a family where there was a lot of criticism, conflict, punishment, or emotional neglect. Maybe the adults around you were unpredictable, and you never knew when something might go wrong.

Perhaps you were treated unfairly, but you had no way to defend yourself.

You couldn’t tell the adults what you really thought. You couldn’t simply leave the situation. You depended on them, and you had to find a way to cope.

So you adapted.

You learned to stay quiet, avoid conflict, or become the child who didn’t cause problems.

You learned to suppress your reactions because expressing them didn’t feel safe or useful.

As an adult, you might no longer be in that environment, but some of the patterns you developed may still influence how you respond to difficult situations.

Perhaps you find it hard to speak up when someone crosses your boundaries.

Maybe you feel uncomfortable disagreeing with people in positions of authority.

Or perhaps you immediately question yourself whenever you feel angry, telling yourself that you shouldn’t feel this way.

Over time, you may become very good at hiding your frustration, even from yourself.

But what happens when something in your current life feels deeply unfair?

You might feel resentment towards your partner, your employer, your family, or the circumstances you find yourself in.

You might want to push back, defend yourself, or tell someone that you have had enough.

But instead, you stay quiet.

You smile. You carry on. You tell yourself that everything is fine.

And you may never give yourself the opportunity to acknowledge what you actually feel.

In my work, I encourage people to become curious about these patterns rather than judging themselves for having them.

Anger is not automatically a bad emotion. It can tell us that something feels unfair, that a boundary has been crossed, or that an important need is not being met.

The goal is not to become an angry person or to start confronting everyone around you.

It is to learn to recognize your emotions and express them in ways that are healthy, appropriate, and respectful.

If you have spent years suppressing frustration, it may be worth exploring what you have been holding inside and whether there are changes you need to make in your life.

2. Unresolved Emotional Experiences and Childhood Patterns

Another area worth exploring is the relationship between earlier emotional experiences and the ways you respond to stress today.

Imagine a child who grows up in a home where expressing anger leads to punishment.

Every time the child becomes upset, they are told to stop complaining, be quiet, or behave.

Eventually, the child learns that expressing frustration is not acceptable.

They might become exceptionally agreeable, helpful, and accommodating.

They learn to read other people’s moods and anticipate their needs. They become skilled at avoiding conflict.

These adaptations may have helped them navigate their childhood environment.

But as adults, they might find it difficult to recognize their own needs or express disagreement without feeling guilty.

For example, they might remain in an unhappy relationship because they don’t want to hurt their partner.

They might accept unreasonable demands at work because they are afraid of disappointing their manager.

They might take responsibility for everyone in their family because saying no makes them feel selfish.

And when they finally have time to rest, they may discover that they cannot relax.

Their mind continues replaying conversations, anticipating problems, or thinking about everything they wish they had said.

These patterns can be emotionally exhausting.

However, it is important to understand that childhood experiences do not affect everyone in the same way, and we cannot assume that a person who grinds their teeth has unresolved childhood trauma.

Bruxism has multiple possible contributing factors, and its exact causes are not fully understood.

Still, if you recognize a pattern of suppressing your feelings, avoiding conflict, or struggling to establish boundaries, understanding where that pattern came from may be useful.

You don’t need to blame your parents or revisit every difficult experience in your past.

The purpose is to understand yourself better.

Why do you react the way you do?

What do you believe will happen if you express your feelings?

Why does saying no feel so uncomfortable?

And are those beliefs still helping you today?

Sometimes, recognizing an old pattern is the first step towards responding differently.

3. Your Body May Be Under Stress Even When You Feel Calm

Have you ever noticed that you can appear perfectly calm while feeling tense inside?

You sit through a difficult meeting, smile politely, and tell everyone that everything is fine.

Meanwhile, your shoulders are raised, your breathing is shallow, and your jaw is tightly clenched.

You might not even notice it until you finally leave the room.

This is particularly common among people who are used to being in control of their emotions.

They may have learned to remain composed in difficult situations, even when they feel frustrated, anxious, or overwhelmed.

From the outside, they appear calm and collected.

But their internal experience may be very different.

Stress can influence how we feel physically, and research recognizes stress and anxiety as factors associated with bruxism.

The National Institute of Dental and Craniofacial Research explains that several factors may contribute to teeth grinding, including stress, anxiety, depression, certain medications, and genetics.

This doesn’t mean that every episode of jaw clenching represents a suppressed emotion.

It does mean that paying attention to stress levels and emotional well-being may be worthwhile, particularly when bruxism occurs alongside other signs of tension.

Consider asking yourself a few questions.

Do you feel responsible for keeping everything under control?

Do you find it difficult to relax because you are always anticipating the next problem?

Do you feel that you must remain strong, regardless of what happens?

Do you suppress your frustration because you believe that expressing it would make you look weak?

You may have developed excellent coping skills that allow you to function under pressure.

But functioning under pressure and feeling genuinely relaxed are not necessarily the same thing.

Sometimes, we become so accustomed to stress that we stop recognizing how much of it we carry.

Learning to identify your emotional responses and finding healthier ways to manage stress can be an important part of taking care of yourself.

4. You Are Unhappy With Your Life but Feel Trapped

Sometimes, the emotional tension we experience isn’t primarily connected to the past.

It may be connected to something happening in our lives right now.

I once worked with a client who was the main breadwinner in her family.

She had a business and worked incredibly hard. She carried a tremendous amount of responsibility and felt that everything depended on her.

She was exhausted.

Her husband was involved in the family situation, but she felt that the responsibility was falling disproportionately on her shoulders.

Deep down, she was angry and resentful.

She didn’t want to continue carrying so much responsibility, but she felt trapped.

She believed she had no other choice.

She couldn’t simply stop working. She couldn’t easily walk away from the responsibilities she had taken on. And she struggled to express how unhappy she was with the situation.

Imagine what it feels like to live that way.

Every day, you wake up and continue doing something you no longer want to do.

You tell yourself that you have to keep going because other people depend on you.

You push your own needs aside because there doesn’t seem to be another option.

You may even feel guilty for resenting the people you love.

And yet, the resentment continues to build.

If you find yourself in a similar situation, I would encourage you to examine the circumstances of your life.

Are you carrying more responsibility than you can reasonably manage?

Are you afraid of what would happen if you stopped doing everything for everyone?

Do you feel that you have no right to ask for help?

Have you convinced yourself that you must continue living a certain way, even though it is making you unhappy?

Sometimes, we become so focused on fulfilling our obligations that we forget we can reconsider how those obligations are distributed.

You might not be able to change everything immediately.

But you may be able to establish boundaries, communicate your needs, ask for support, or begin making a plan for a different arrangement.

If you experience jaw clenching or teeth grinding, these questions may help you identify stressors worth addressing.

They are not a diagnosis or proof that your emotional life is causing your bruxism. Rather, they are an opportunity to understand the bigger picture of your well-being.

5. You Are Holding Back What You Really Want to Say

Let’s talk about relationships.

Have you ever wanted to tell your partner something important but decided not to?

Perhaps you wanted to explain that you felt neglected, unsupported, or misunderstood.

Maybe you were frustrated by something they repeatedly did.

You rehearsed the conversation in your head.

You imagined how they might react.

You worried that they would become defensive, get upset, or accuse you of starting an argument.

So you decided it was easier to keep quiet.

You swallowed your words and carried on as if nothing had happened.

But the issue wasn’t resolved.

You were still upset, and the conversation continued in your mind.

This is a pattern I often encourage people to examine: the difference between choosing not to react impulsively and consistently denying yourself the opportunity to express what matters to you.

There is a healthy difference between the two.

You don’t need to express every passing frustration. Sometimes, letting something go is the right decision.

But if you repeatedly silence yourself to avoid conflict, you may gradually develop resentment.

You might become irritable over seemingly insignificant things.

You may withdraw emotionally from your partner.

Or you may find yourself feeling tense whenever the subject comes up.

The same pattern can occur in friendships, family relationships, and professional environments.

You might be afraid to express your opinion because you don’t want to disappoint someone.

You might agree to things you don’t want to do because you are worried about being rejected.

You might believe that a good partner, friend, or employee should always be accommodating.

But healthy relationships require communication.

Expressing yourself respectfully gives other people an opportunity to understand your perspective, even if they don’t always agree with you.

You can say, “I’m struggling with this situation, and I need us to talk about it.”

You can explain that something is not working for you.

You can ask for a change without attacking the other person.

And you can learn to tolerate the discomfort that sometimes comes with honest conversations.

Your voice is important. Your needs matter. And you can learn to express yourself without becoming aggressive or abandoning your kindness.

Communication is a skill, not a personality trait that some people are born with and others can never develop.

If you have spent years avoiding difficult conversations, you can begin practising new ways of expressing yourself.

Over time, healthier communication may reduce some of the stress associated with unresolved disagreements.

6. You Are Angry at Your Job but Afraid to Speak Up

The same pattern can occur in the workplace.

Perhaps you are frustrated with your boss, manager, or supervisor.

You disagree with the company’s values. You feel that you are being treated unfairly, or you believe that your workload is unreasonable.

You have ideas about how things could be improved, but you don’t feel comfortable expressing them.

Maybe you are worried about losing your job.

Perhaps you are afraid of being labelled difficult or uncooperative.

Or maybe you have learned that speaking up rarely changes anything.

So you keep your opinions to yourself.

You attend meetings, complete your work, and maintain a professional attitude.

But underneath that composed exterior, you feel increasingly frustrated.

This can be particularly difficult if you are someone who takes pride in being reliable and responsible.

You may believe that you must tolerate an unfair situation because you have financial obligations or people depending on you.

And perhaps, for now, you do need to remain in that job.

Not every situation allows for immediate change, and sometimes speaking up requires careful consideration of the potential consequences.

But remaining silent indefinitely can leave you feeling powerless.

Instead of assuming that you have no options, consider what is realistically within your control.

Could you have a constructive conversation with your manager?

Could you establish clearer boundaries around your workload?

Could you document concerns and seek support through appropriate workplace channels?

Could you begin exploring other employment opportunities?

Even if you cannot change your circumstances immediately, developing a plan can help you regain a sense of agency.

And if you notice that work-related stress follows you home, affects your sleep, or leaves you feeling constantly tense, it may be time to take your emotional well-being more seriously.

Your job is an important part of your life, but it doesn’t have to define your entire identity.

7. You Keep Sacrificing Yourself for Everyone Else

This is a big one.

Some people spend their entire lives taking care of others.

They help their parents, support their partners, raise their children, assist their friends, and make themselves available whenever someone needs something.

They are the dependable ones.

The people everyone turns to.

The people who somehow find the time and energy to solve everybody else’s problems.

And when you ask them how they feel, they often say, “I’m fine.”

They might even insist that they aren’t angry or resentful.

But let’s look a little deeper.

How often do you say yes when you actually want to say no?

How often do you cancel your own plans because someone else needs your help?

How often do you take responsibility for something because you assume nobody else will do it properly?

How often do you feel frustrated with people for expecting so much from you, even though you have never told them that you are struggling?

Sometimes, we create a pattern in which we repeatedly put ourselves last and then feel resentful when other people accept the arrangement.

We may expect them to recognize how much we are sacrificing without ever communicating our needs.

And when they don’t, we feel disappointed.

The difficulty is that people cannot always know what we need if we never tell them.

They may have become accustomed to our willingness to help. They may genuinely believe that we are comfortable with the arrangement.

Meanwhile, we become increasingly exhausted.

This is why boundaries are so important.

A boundary is not a punishment, and it doesn’t mean you stop caring about other people.

It means recognizing that your time, energy, and needs matter too.

You can love someone without solving every problem for them.

You can be supportive without taking responsibility for their emotions.

You can help when you have the capacity and say no when you don’t.

And you can ask other people to contribute rather than assuming that everything must fall on your shoulders.

If you recognize this pattern in yourself, consider whether your frustration might be telling you that something needs to change.

You don’t need to become less kind.

You may need to become more honest about what you can realistically give.

Can Suppressed Anger Cause Teeth Grinding?

This is an important question, and I want to make a distinction.

Stress, anxiety, and emotional distress are recognized factors associated with bruxism. However, there is not sufficient evidence to conclude that suppressed anger or unresolved childhood trauma is the direct cause of teeth grinding in every person who experiences it.

Bruxism can involve multiple contributing factors, including sleep-related processes, genetics, medications, and other physical or psychological influences.

If you grind your teeth, it does not automatically mean you have unresolved anger, that you are unhappy with your life, or that you are suppressing your emotions.

However, if you recognize yourself in the patterns described above, exploring your emotional well-being may still be valuable.

You can ask yourself whether you are experiencing ongoing stress, whether there are situations you need to address, and whether you have developed habits of ignoring your own needs.

These questions are worthwhile even if they turn out to be unrelated to your teeth grinding.

The goal is not to convince yourself that every physical symptom has an emotional explanation.

It is to approach your health from more than one perspective while ensuring that you receive appropriate care.

What Can You Do About Teeth Grinding and Jaw Clenching?

If you suspect you have bruxism, I encourage you to approach the problem from both a physical and emotional perspective where appropriate.

1. Speak to Your Dentist

Your dentist can assess signs of tooth wear, damage, jaw tenderness, and other symptoms.

Depending on your situation, they may recommend a mouth guard or another treatment to protect your teeth.

A mouth guard can be particularly useful because it creates a barrier between your teeth and helps prevent damage from grinding.

It may not eliminate the underlying activity, but protecting your teeth is an important part of managing bruxism.

You can learn more about diagnosis and treatment from the Mayo Clinic’s guide to bruxism.

Please don’t stop using a prescribed or recommended dental appliance because you are exploring emotional factors.

2. Pay Attention to Your Stress Levels

Consider what is happening in your life when your symptoms become more noticeable.

Are you going through a particularly stressful period?

Are you experiencing conflict in a relationship?

Are you taking on more responsibility than you can comfortably manage?

Are you constantly worrying about something you cannot control?

Keeping a simple record of your symptoms, sleep, stress levels, and relevant changes in your routine may help you identify patterns worth discussing with your healthcare providers.

Stress-management practices such as regular exercise, relaxation, and meditation may also be useful for some people.

3. Practise Recognizing Your Emotions

Many people can identify physical discomfort more easily than emotional discomfort.

They know that their jaw is tight, their shoulders are tense, or their head hurts.

But when asked how they feel, they might say, “I’m fine.”

Try becoming more curious about your emotional experience.

Are you frustrated?

Disappointed?

Overwhelmed?

Resentful?

Afraid of what might happen if you speak up?

You don’t have to act on every emotion. The first step is simply to recognize it without judging yourself.

Once you understand what you are feeling, you can decide how to respond constructively.

4. Learn to Express Yourself

If you tend to avoid conflict, start with small steps.

Express a preference instead of automatically agreeing with someone else.

Ask for help when you need it.

Tell someone when a situation is bothering you, using calm and respectful language.

Practise saying no to requests that you cannot reasonably accommodate.

You don’t need to change your personality or become confrontational.

You can learn to communicate clearly while remaining a caring and considerate person.

5. Explore the Emotional Patterns Behind Your Stress

If you repeatedly find yourself in situations where you feel powerless, overwhelmed, or unable to express your needs, consider exploring those patterns with an appropriate professional.

You might benefit from counselling, psychotherapy, stress-management support, or another approach suited to your circumstances.

For some people, hypnotherapy may also be a useful complementary option for exploring emotional experiences and beliefs.

The important thing is to choose an approach that fits your needs and to seek medical or dental care for the physical symptoms.

How Hypnotherapy May Help You Explore Emotional Patterns

In my work as a hypnotherapist, I help clients explore the experiences, beliefs, and emotional patterns that may be influencing how they feel and behave today.

Sometimes, a person comes to me because they feel anxious or overwhelmed.

As we explore their concerns, they begin to recognize a familiar pattern.

They have difficulty saying no.

They feel responsible for keeping everyone happy.

They are afraid of disappointing people.

They suppress frustration because they believe expressing it will lead to rejection or conflict.

These patterns may have developed for understandable reasons, but they may no longer be serving them.

During a hypnotherapy session, we explore the concern the client wants to address and use guided hypnotic techniques to help them reflect on their experiences and perspectives.

The process may help them examine the beliefs they hold about themselves, their relationships, and the world around them.

For example, someone who has always believed that being a good person means never disappointing anyone might begin to consider a different perspective.

They can recognize that caring for others doesn’t require abandoning their own needs.

They can learn that disagreement doesn’t automatically mean rejection.

They can understand that expressing frustration respectfully is not the same as being aggressive.

And they can begin practising new behaviours that better reflect their values.

This work is not about forcing yourself to release anger or assuming that anger is the cause of a physical symptom.

It is about understanding yourself more clearly and exploring whether there are emotional patterns you would like to change.

Hypnotherapy has not been established as a standalone treatment for bruxism, and I cannot promise that addressing emotional patterns will stop teeth grinding or eliminate headaches. Outcomes vary, and persistent physical symptoms should be assessed by appropriate healthcare professionals.

However, if anxiety, stress, people-pleasing, or difficulty expressing yourself are concerns in their own right, exploring these issues may be worthwhile.

What If Your Jaw Is Telling You That Something Needs Attention?

Let me leave you with a few questions.

Are you happy with the way you are living your life?

Do you feel that you can express yourself honestly in your relationships?

Are you carrying responsibilities that have become too heavy?

Do you regularly put other people’s needs before your own?

Are there conversations you have been avoiding for months or even years?

Do you feel angry about something but tell yourself that you have no right to be upset?

You don’t have to answer all these questions immediately.

And you certainly don’t need to assume that your answers explain your bruxism.

But if you recognize yourself in these patterns, perhaps it is time to pay attention to what you need.

You don’t have to become an angry person to acknowledge anger.

You don’t have to become selfish to establish boundaries.

You don’t have to start arguments to express your opinions.

And you don’t have to continue sacrificing your well-being simply because you have always done so.

You can learn to communicate more openly, make different decisions, and build relationships in which your needs matter too.

You can remain kind without remaining silent.

You can be responsible without carrying everything alone.

And you can begin making changes that help you feel more comfortable in your own life.

Taking care of yourself means looking after your physical health, but it can also mean becoming more aware of your emotional experiences and the patterns that shape your everyday decisions.

If you are struggling with teeth grinding or jaw clenching, start by seeking appropriate dental advice. And if you recognize a deeper pattern of anxiety, resentment, or difficulty expressing yourself, consider exploring that as well.

You deserve to feel heard, including by yourself.

Frequently Asked Questions About Bruxism

1. What is the most common cause of teeth grinding?

Bruxism does not have one universal cause. Factors associated with teeth grinding and jaw clenching include stress, anxiety, genetics, certain medications, lifestyle factors, and sleep-related processes. A dentist or healthcare professional can help assess your symptoms and identify relevant contributing factors.

2. Can stress cause jaw clenching and teeth grinding?

Stress and anxiety are recognized factors associated with bruxism. Some people notice more jaw tension or teeth grinding during stressful periods. However, stress is not the only possible explanation, and persistent symptoms should be assessed by a dentist or healthcare professional.

3. Can suppressed anger cause bruxism?

There is insufficient evidence to establish suppressed anger as a direct cause of bruxism. However, emotional distress and stress are associated with teeth grinding. If you regularly suppress frustration or avoid expressing your needs, exploring these patterns may be helpful for your emotional well-being, even if they are not the cause of your bruxism.

4. Can childhood trauma contribute to teeth grinding?

Some people experience ongoing stress or emotional difficulties related to earlier experiences, but childhood trauma is not an established universal cause of bruxism. Teeth grinding can have multiple contributing factors. If past experiences continue to affect your emotional well-being, a qualified professional can help you explore appropriate support.

5. Can a mouth guard stop teeth grinding?

A mouth guard can help protect your teeth from damage caused by clenching and grinding. It may not eliminate the grinding activity itself. Your dentist can recommend an appropriate appliance and discuss other treatment options based on your symptoms.

6. Can hypnotherapy help with teeth grinding?

Hypnotherapy is not an established standalone treatment for bruxism. However, it may be considered as a complementary approach for exploring stress, anxiety, and emotional patterns when these are concerns for the individual. Evidence that hypnotherapy directly reduces bruxism is limited, so dental assessment and appropriate treatment remain important.

7. How do I know if I grind my teeth at night?

Possible signs include waking up with jaw soreness, headaches, facial discomfort, tooth sensitivity, or noticing that your teeth appear worn or damaged. A sleeping partner may also hear grinding sounds. A dentist can examine your teeth and jaw and help determine whether bruxism may be responsible.

8. When should I see a dentist about jaw clenching?

Arrange a dental appointment if you experience persistent jaw pain, recurring headaches that may be related to clenching, tooth sensitivity, or signs of tooth damage. Early assessment can help identify the problem and reduce the risk of further damage.
