Treatment overview
Protecting teeth from the effects of clenching and grinding
Bruxism can occur during sleep or while awake. Repeated clenching and grinding may contribute to tooth wear, cracks, restoration damage, muscle fatigue and jaw-joint symptoms. A custom night guard is made to fit the patient’s bite and provide a protective surface between the teeth.
A night guard does not necessarily remove the cause of bruxism, so the assessment also considers bite, jaw-joint symptoms, stress-related habits, sleep factors and the condition of the teeth and restorations.
Assessment
Common signs of bruxism or excessive bite forces
Flattened, worn or chipped teeth
Morning jaw tiredness or muscle soreness
Repeated fracture of fillings or restorations
Clenching noticed during the day
Grinding sounds reported by a partner
Jaw-joint clicking, discomfort or stiffness
Headaches that may be associated with muscle tension
Why patients consider it
Key benefits
The guard absorbs contact between opposing teeth and helps reduce direct wear.
Crowns, veneers and fillings may benefit from protection where clenching is present.
A professionally made appliance is shaped to the individual teeth and bite.
Wear patterns on the appliance can help the dentist monitor bite forces over time.
Step by step
Your treatment journey
Assessment
Teeth, restorations, jaw muscles and joints are examined and the pattern of wear is discussed.
Impression or digital scan
An accurate record of the teeth is taken for a custom appliance.
Laboratory fabrication
The guard is made from a material and thickness selected for the clinical situation.
Fit and bite adjustment
The appliance is checked for retention, comfort and balanced contact.
Review
The guard and the teeth are reviewed periodically for wear, fit and symptom changes.
Long-term success
Care and aftercare
A clean, well-fitting appliance lasts longer and is more comfortable to use.
- Rinse and clean the guard after each use with cool or lukewarm water
- Store it dry in a ventilated protective case
- Avoid hot water, which can distort some appliance materials
- Bring the guard to dental reviews so fit and wear can be checked
Common questions
Night Guard for Bruxism FAQ
Will a night guard stop me grinding my teeth?
It mainly protects teeth from the effects of grinding and clenching. Bruxism may have several contributing factors, so additional management may be appropriate.
Can I use an over-the-counter guard?
Stock or boil-and-bite guards may fit less precisely and can alter bite contacts. A custom appliance allows the dentist to control fit and occlusion.
How long does a night guard last?
Lifespan depends on grinding intensity, material, cleaning and changes to the teeth. Regular checks help identify when replacement is needed.
