Quick answer. Bruxism is involuntary teeth grinding or clenching, often during sleep, that can wear down teeth and cause jaw pain. A custom night guard (often from around S$400 upward) is the usual first-line protection; Botox to the jaw muscles is sometimes used in addition.

Bruxism is the involuntary grinding or clenching of teeth, which can happen during sleep (sleep bruxism) or while awake. Many people are unaware they do it until a partner notices the grinding sound or a dentist spots tooth wear.
Left unmanaged, it can damage teeth, strain the jaw muscles and joints, and cause headaches. The good news is that protective and management options are widely available. The figures below are typical Singapore private-market ranges, not quotes from any specific clinic.
At a glance
| Option | What it does | Typical price range (SGD) |
|---|---|---|
| Custom night guard | Cushions teeth, prevents wear | From ~$400 upward |
| Botox to jaw muscles | Relaxes overactive muscles | From ~$500 per session |
| Stress / habit management | Addresses triggers | Varies |
| Dental consultation | Diagnosis and monitoring | $50 – $250 |
What causes bruxism
The exact cause is not always clear, but bruxism is linked to several factors:
- Stress, anxiety, and emotional tension
- Sleep disorders, including sleep apnoea and snoring
- Bite misalignment or missing teeth
- Certain medications, caffeine, alcohol, and smoking
Sleep bruxism in particular is thought to be related to arousals during sleep rather than purely a dental problem, which is why management often looks at lifestyle and sleep too.
Effects and warning signs
Common signs include:
- Worn, flattened, chipped, or sensitive teeth
- Jaw soreness, tightness, or clicking
- Morning headaches or aching around the temples
- A grinding sound noticed by a sleep partner
Over time, untreated bruxism can crack teeth, damage fillings or crowns, and contribute to temporomandibular joint (TMJ) problems.
Night guards (occlusal splints)
A custom-fitted night guard is the most common first-line treatment. Made from impressions or scans of your teeth, it forms a protective barrier so the upper and lower teeth do not grind directly against each other, cushioning the force and protecting tooth surfaces.
Custom guards fit better and last longer than over-the-counter versions. A night guard does not stop the grinding itself but protects the teeth and can ease muscle strain.
Botox for bruxism
Botulinum toxin (Botox) can be injected into the jaw-clenching muscles (mainly the masseter) to reduce their force, which lessens grinding intensity and can relieve associated pain and even slim a bulky jawline. Effects are temporary, typically lasting a few months, so repeat sessions are needed.
Botox is often combined with a night guard in more severe cases rather than used alone. It should be administered by a suitably trained, qualified clinician after proper assessment.
Self-care and addressing triggers
- Manage stress through relaxation techniques, exercise, or counselling where relevant
- Reduce caffeine and alcohol, especially in the evening
- Avoid chewing gum or non-food objects that keep jaw muscles active
- Get sleep problems such as snoring or sleep apnoea assessed
These measures complement, rather than replace, a dentist’s assessment and protective devices.
When to see a dentist and costs
See a dentist if you notice tooth wear or sensitivity, jaw pain or clicking, frequent morning headaches, or if a partner reports grinding sounds. Early assessment helps prevent lasting tooth and joint damage.
Night guards and Botox for bruxism are generally not MediSave-claimable, as they are not classified as surgical procedures, and they are typically not covered by insurance. Dentists in Singapore are regulated by the Singapore Dental Council (SDC).
What to expect at the dental visit
At an assessment for suspected bruxism, the dentist will ask about your symptoms, sleep, stress levels, caffeine and alcohol intake, and any medicines you take. They will examine your teeth for flattening, chips, cracks or worn fillings, check the jaw muscles and the temporomandibular joint for tenderness or clicking, and look at how your teeth meet when you bite. If sleep bruxism is suspected and there are signs of snoring or interrupted breathing, they may suggest assessment for a sleep disorder. Photographs or scans of your teeth may be taken so that wear can be tracked over time, and to make a custom night guard if one is recommended.
Caring for a night guard
If you are fitted with a night guard, looking after it keeps it effective and hygienic. Rinse it under cool water after each use and brush it gently; avoid hot water, which can warp the material. Store it dry in its ventilated case, away from pets, who are often attracted to it. Bring it to your dental check-ups so the dentist can inspect the fit and the wear pattern, which also shows how active your grinding is. A guard that becomes loose, cracked or heavily worn should be reviewed, as a poorly fitting device may be uncomfortable or less protective.
Special situations
Children commonly grind their teeth, especially during sleep, and many grow out of it as their adult teeth and jaws develop; persistent grinding or tooth damage should still be checked by a dentist. In adults, new or worsening grinding can sometimes follow a change in medication, increased stress, or the onset of a sleep problem, so it is worth mentioning recent life changes. If you wear braces or have dental implants, crowns or veneers, tell your dentist, as protecting this work from grinding forces may change the recommended approach.
Common questions
Will a night guard stop me grinding?
A night guard does not stop the grinding itself; it cushions the force and protects your teeth and fillings from wear, and it can ease muscle strain. Addressing triggers such as stress and sleep problems works alongside it.
Are night guards or Botox claimable?
Night guards and Botox for bruxism are non-surgical and generally not MediSave-claimable, and they are usually not covered by insurance. Confirm costs and what is included with your clinic before proceeding.
