TMD · Bruxism · Cologne

When your jaw will not settle.

A tired jaw in the morning. Clenching during the day. Pain when chewing. These observations deserve attention. A dental examination can help identify what is behind them and what to do next.

TMD and teeth grinding are sometimes related, but they describe different things.

Three useful distinctions

Understand first. Then decide.

Bruxism

Clenching is not always audible.

Bruxism describes chewing muscle activity: grinding, clenching or bracing the jaw. It can occur while awake or asleep.

  1. Awake: often unnoticed in daily life
  2. Asleep: not under conscious control
When does it matter?

Bracing without tooth contact can also be part of it. Bruxism alone is not automatically a disorder. Symptoms, damage and individual risks determine its significance.

TMD

Consider muscles and joints too.

Temporomandibular disorders (TMD) are conditions involving pain or impaired function of the chewing system, particularly the chewing muscles and jaw joints.

  1. Chewing muscles: tension and pain
  2. Jaw joints: movement and function
Is TMD the same as grinding?

No. They can occur together, but do not have to. Similar symptoms may also have other causes. The examination therefore includes distinguishing dental conditions and other sources of pain.

Occlusal splint

Protection with a clear purpose.

A splint can protect teeth and restorations from mechanical stress. Whether it is appropriate depends on the findings and the treatment aim.

  1. Define the aim
  2. Check the fit
  3. Review progress
Does a splint stop grinding?

It does not reliably eliminate the muscle activity permanently. Relief from TMD pain cannot be promised either. New pain while wearing a splint should be assessed by a dentist; please do not adjust it yourself.

Clinical information and sources

What you might notice

Five observations to discuss.

No single sign establishes TMD or bruxism. It helps to note when you first noticed something and the situations in which it occurs.

  1. Pain when chewing or yawning

    Recurring discomfort in the cheeks, in front of the ear or in the jaw should be examined.

  2. A jaw that catches

    Restricted mouth opening or repeated locking warrants assessment. Urgent warning signs are listed with the quick check.

  3. Tired chewing muscles in the morning

    Also mention any night-time grinding sounds that someone else has noticed. These are clues, not a diagnosis.

  4. Changes to your teeth

    New sensitivity, chipped edges or increasing wear can have various causes. This is why the teeth are also examined.

  5. Sleep that leaves you tired

    Observed breathing pauses and marked daytime sleepiness should also be discussed with a doctor. Grinding alone does not mean sleep apnoea.

Five questions for orientation

TMD quick check. What have you noticed?

After each choice, general information about that topic appears immediately. The questions help you prepare for a conversation. They are not a scientifically validated test and do not provide a diagnosis, assess your symptoms or recommend a treatment.

Optional, with no sign-in. Your choices are neither saved nor sent, and are not passed to the booking service.

Do you have recurring pain in your jaw, in front of your ear or in your chewing muscles – for example when chewing or yawning?
Does opening or moving your mouth feel restricted, or does your jaw repeatedly catch?
Do you notice daytime clenching or jaw tension, or has someone reported that you grind your teeth at night?
Have you noticed new sensitive areas, chipped tooth edges or increasing tooth wear?
Has someone noticed pauses in your breathing during sleep, or do you experience pronounced daytime sleepiness?

Without JavaScript, no additional guidance is displayed. Use the questions to prepare for a conversation; if you have symptoms or questions, please arrange an appointment.

Discuss it in person rather than self-diagnose.

Choosing “No” does not rule out TMD, bruxism or other conditions. If you have symptoms or questions, please arrange an in-person examination. Your usual check-ups remain important.

Possible approaches after the examination

What may help depends on the findings.

For TMD, initial care usually focuses on conservative, reversible measures. Not everyone needs a splint or the same combination of approaches.

  1. Notice your habits

    For daytime clenching, reminders may help you consciously relax your chewing muscles. Suitable exercises should be demonstrated for your individual needs.

  2. Protect the teeth where needed

    If an occlusal splint is an option, its purpose, wearing instructions and reviews are discussed. Protection and pain management serve different purposes.

  3. Support movement and manage symptoms

    Physiotherapy may form part of treatment for muscle or joint symptoms. The examination guides which exercises are appropriate.

  4. Consider sleep and other pressures

    Relaxation, sleep habits and further medical assessment where needed may be important. Mention any medicines you take; do not stop them on your own.

  5. Look further if pain persists

    Depending on progress, other clinical disciplines and pain management support may be useful. The plan is reviewed in light of symptoms and findings.

Prepare for your examination

From your observations to the next step.

  1. Describe your symptoms

    When did it start? What changes the pain? You are welcome to bring brief notes, a list of medicines and any splint you already use.

  2. Examine the teeth and jaw

    Depending on your symptoms, the assessment includes the teeth, chewing muscles, jaw joints and range of movement. Further investigations depend on the specific clinical question.

  3. Agree on a plan together

    We discuss the findings and possible next steps, including the treatment aim, alternatives, what is involved and an appropriate time for review.

Frequently asked questions

Other questions you may have.

Does every clicking sound need treatment?

Painless joint sounds without restricted movement are common and usually need no treatment. If pain, restricted movement or repeated locking develops, this should be examined.

Is teeth grinding always caused by stress?

No. Stress can contribute, but does not explain every case. Sleep, inherited factors, substances such as caffeine or alcohol, and certain medicines may also play a role.

Does my bite need to be permanently changed?

Not as a routine approach. The S3 guideline advises against reshaping or permanently building up teeth to treat the cause of bruxism. Restoring teeth that are already damaged is a separate question.

Can I start by discussing what I have noticed?

Yes. You do not need to diagnose yourself or decide on a splint beforehand. An examination and a conversation are the starting point.
