Night guards and bruxism - protecting veneers and implants
Why UK patients who grind must wear a custom night guard after veneers or implants — bruxism signs, guard types, how to get one in the UK, and the clinical consequences of not wearing one.
Bruxism (tooth grinding or clenching) generates bite forces 3–10× higher than normal chewing. Without a custom night guard, these forces will chip porcelain veneers, fracture crown margins, stress implant components, and accelerate wear on natural teeth. If Picasso prescribed a guard, wear it every night. If you grind and have no guard, ask your UK dentist to fabricate one immediately.
What bruxism does to dental restorations
Normal chewing generates approximately 70–150 N of biting force. Bruxism during sleep generates 300–900 N — with no food to absorb the shock, sustained for hours without the conscious control that limits daytime biting.
| Restoration type | Risk without a night guard |
|---|---|
| Porcelain veneers | Surface wear, edge chipping, full fracture |
| Emax crowns | Crown fracture, cement failure |
| Implant crowns | Screw loosening, component fracture, peri-implant bone stress |
| Composite veneers | Rapid surface wear; lifespan cut from 5–7 years to 2–3 years |
| Bridges | Pontic fracture, abutment tooth stress |
| Natural teeth | Attrition, exposed dentine, sensitivity |
Signs you may be grinding
- Morning jaw ache or fatigue
- Morning headache (temporal or frontal)
- Tooth sensitivity in the morning that improves during the day
- Flattened or worn-looking back teeth (visible on X-ray or clinical exam)
- Partner reports grinding sounds during sleep
- Daytime jaw clenching during concentration or stress
- Cheek biting or a visible cheek ridge inside the mouth
If three or more of these apply, discuss bruxism management before any ceramic restoration.
Types of night guard
| Type | Material | Suitability |
|---|---|---|
| Custom hard acrylic (lab-made) | Hard resin | Recommended for veneers and implants — best force distribution |
| Custom soft silicone | Soft silicone | Easier to tolerate; slightly less protective; suitable for mild grinders |
| Dual-laminate (hard outer, soft inner) | Combined | Good for moderate grinders who cannot tolerate fully hard guards |
| Over-the-counter boil-and-bite | Soft EVA | Not recommended for porcelain veneers or implants |
For porcelain veneers the hard acrylic lab-made guard is the clinical standard. It is the most protective and the most durable.
How to get a night guard in the UK after your trip
- Inform your UK dentist that you have had veneer or implant treatment and need a custom night guard
- Impressions or a digital scan are taken (10-minute appointment)
- The lab fabricates the guard in 1–2 weeks
- Fitting appointment — minor bite adjustments
- Wear every night; bring it to hygienist appointments for inspection
Cost range: £150–£400 for a custom hard acrylic guard.
Wearing and caring for your guard
Wearing:
- Put it in immediately before sleep
- Keep it on your bedside table to build the habit
- Travel with it in hand luggage — never check it in a suitcase
Cleaning:
- Rinse with cold water immediately after removal
- Brush with a soft toothbrush and mild soap — not toothpaste (abrasive)
- Air dry fully before storing in the ventilated case provided
- Disinfect weekly with a denture tablet or retainer cleaner
Lifespan: Hard acrylic guards typically last 2–5 years before wearing through. Replace when you can see deep grooves or perforations — a worn guard is no longer protective.
Botox for bruxism — an adjunct, not a replacement
Masseter Botox injections relax jaw muscles and reduce grinding force. Some patients find this reduces symptoms significantly. It wears off in 3–6 months — continue wearing the night guard as force returns.
Use it as an adjunct, not as a replacement for the guard.
Disclosing bruxism before treatment
Disclose grinding in your free quote request. The clinical team will include guard fabrication in the quote, adjust material choices if needed, and set appropriate warranty expectations. Undisclosed bruxism leading to veneer failure is not covered under warranty — honesty protects the clinical outcome.
