What are teeth grinding and jaw clenching?
Bruxism is the collective term for grinding and clenching. Grinding involves movement or contact between teeth, while clenching involves sustained or repeated tightening. Either can occur during sleep or while awake. People are not always aware of the behaviour, and not every occurrence causes harm or requires treatment.

Both can occur during sleep or while awake. People may be unaware of the behaviour, and not every occurrence causes damage or requires treatment.
Which symptoms warrant assessment?
Suspected grinding, jaw clenching, tooth wear or damaged restorations can justify a dental assessment. These signs do not prove bruxism by themselves. Tandartspraktijk Mathenesse in Rotterdam examines the individual dental situation and discusses suitable next steps. The practice is affiliated with KNMT.
Possible signs include visible wear, chipped teeth or restorations, sensitivity, jaw-muscle fatigue, discomfort on waking, a partner reporting grinding, or awareness of daytime clenching. These findings are nonspecific. Tooth wear, jaw pain and headache do not prove bruxism and can have other dental or medical explanations.
Assessment can consider symptoms and timing, daytime awareness, partner observations, wear or damage, existing restorations, bite, jaw movement and chewing muscles where relevant. Medication, health information, habits and possible alternative explanations can also matter. Any additional investigation depends on the symptoms and examination findings.
Bruxism does not have one universal cause. Sleep-related processes, stress or concentration, habits, alcohol, smoking, medication, health and sleep conditions can be associated with grinding or clenching. Stress is not always the cause, and relaxation alone cannot be promised to resolve the behaviour. Discuss medication concerns with the prescribing clinician rather than changing treatment yourself.
A partner may notice night-time grinding, or you may become aware of clenching during the day. Wear, chips, damaged restorations and jaw fatigue can justify assessment. These findings are not definitive. A dentist considers the history, dental examination and possible alternative explanations before discussing next steps.
If you already use a splint, bring it so the dentist can consider its condition and fit where relevant.

Which treatment options can be discussed?
A splint may be considered for selected patients. A suitable appliance can create a protective surface between teeth and reduce direct mechanical wear to natural teeth or restorations. In some situations it may support management of certain jaw complaints. It does not necessarily stop grinding or clenching, remove the cause, eliminate pain, prevent all damage or treat a sleep disorder.
Not necessarily. A suitable splint may create a protective surface between the teeth and reduce direct mechanical wear. It does not automatically stop grinding or clenching, remove the underlying cause, eliminate pain, prevent all damage or treat a sleep disorder. Suitability depends on individual assessment.
How is appliance suitability decided?
Suitability depends on symptoms, dental findings, bite, existing restorations and treatment goals. The dentist discusses an appropriate appliance type, material, wearing schedule and production method only after an individual assessment.
The dentist also considers relevant health information and alternative explanations. Assessment determines whether monitoring, advice, an appliance or another step may be appropriate; it does not guarantee that a particular splint will be supplied.
Other management and possible referral
Management follows the findings and possible contributing factors. Options can include awareness of daytime clenching, individual habit advice, monitoring, management of dental damage, exercises or physiotherapy when appropriate, and medical or specialist assessment when another condition is suspected. Ask the practice which services or referral options are currently available.
No. Bruxism-associated wear or damage does not automatically require a filling, crown or another restoration. Extent, activity, symptoms, how much natural tooth remains and risk of further damage guide the decision. Any restorative option follows assessment and does not by itself stop grinding or clenching.
An examination determines which explanation, monitoring or next step may be appropriate; Mathenesse provides custom night guards when these are appropriate for the findings.

How does the night guard process work?
We discuss symptoms and assess dental damage, bite and, where relevant, jaw muscles. When appropriate, a night guard is made to measure and fitted. You receive individual wearing and cleaning advice. An appliance protects teeth but does not necessarily stop grinding.
You can ask questions in English at every stage.
Maintenance, fit and replacement
At reviews, we assess the fit and condition of the appliance. Follow your individual wearing and cleaning advice.
A splint has no universal lifespan or automatic replacement interval. Forces, wear, fit, material, oral changes, care, accidental damage and use affect its condition. Contact the practice if an appliance cracks, becomes sharp, no longer fits, causes persistent discomfort, changes the bite significantly or becomes difficult to clean. Do not force or alter it yourself.
A splint has no fixed lifespan or automatic replacement date. Grinding forces, wear, fit, material, oral changes, care, accidental damage and use all affect its condition. Adjustment, repair or replacement should depend on safety, fit and clinical assessment rather than the appliance’s age alone.
Costs and insurance coverage
Cost can depend on the consultation and examination, clinically indicated diagnostics, appliance type, technical work, fitting, adjustment and treatment of existing dental damage. In the Netherlands, dental tariffs follow the statutory NZa framework. There is no fixed price on this page. Insurance coverage depends on the treatment, indication and policy conditions; ask about expected costs and confirm current coverage with your insurer.
We explain the diagnosis, available options and expected costs before treatment.

When is prompt assessment important?
Seek prompt advice for sudden severe jaw pain, significant swelling, trauma, inability to open or close the mouth normally, a broken tooth, increasing dental pain or an appliance causing injury. Difficulty breathing or swallowing needs urgent medical assessment. Use the emergency dental care instructions for urgent dental problems outside practice hours.
