Contacts are shared, not concentrated
If one or two front teeth take all the load, those are the ones that break. We let the canines meet first in lateral movement so the incisors are loaded only momentarily.
Bruxism and Veneers
I grind my teeth.
Can I still have veneers?
It comes up in almost every consultation. The answer is not yes or no — it is that the conditions change. Bruxism is a documented risk factor, but with a design that channels the force elsewhere and a guard worn at night, we usually can proceed.
PORCELAIN VENEER The Risk
Grinding genuinely raises the risk of failure
In a study following 318 veneers for nearly ten years on average, existing parafunction such as bruxism carried a 7.7-times greater risk of failure. Ceramic handles compression well but tolerates twisting forces poorly. Lateral load repeated all night loosens the bonded interface little by little, and it surfaces one day as a chip or a debond.
Self Check
Signs that you may be grinding
Most people have no idea they do it. If two or more of these apply, it has to be verified at the diagnosis stage.
- Your jaw feels tight or your temples feel heavy in the morning.
- The edges of your lower front teeth are worn flat like glass.
- The chewing surfaces of your molars look polished smooth.
- There are wedge-shaped notches at the necks of the teeth, and they feel sensitive.
- Someone sleeping nearby has told you they hear a sound at night.
- Teeth feel sensitive or slightly loose during stressful periods.

Design Changes
Grinding changes the design
The veneer is the same; the structure that carries the load is not. These four things change in a bruxism case.
Length is not pushed
The more length we add, the longer the lever and the higher the fracture risk. We plan slightly shorter than the ideal, and confirm it after weeks in temporaries when needed.
Bonding stays in enamel wherever possible
Once preparation reaches dentin, adhesion drops sharply — in the literature, veneers bonded to dentin were roughly ten times more likely to fail. In a grinding case, minimal reduction is a safety margin.
Material and thickness are reconsidered
Thin, translucent feldspathic porcelain is the aesthetic favourite, but where heavy load is expected we secure thickness at the incisal edge or blend in a stronger material.
{ Placing veneers on a grinder means designing to redirect the force, not remove it. }
Decision
What decides whether we proceed
Bruxism is not one condition. Severity and what comes with it change the answer, and we set it together at the consultation.
| Condition | Judgement | Done alongside |
|---|---|---|
| Mild grinding, enamel intact | Usually can proceed | Night guard · six-month checks |
| Moderate grinding with worn incisors | Proceed with conditions | Load-sharing design · night guard required · longer temporary phase |
| Severe grinding, collapsed bite, heavy clenching | Veneers alone not advised | Stabilise the bite first; consider crowns or other options |
| With TMJ pain or limited opening | On hold | Re-evaluate after the joint symptoms settle |
Aftercare
What has to be kept up afterwards
In grinding cases, longevity is decided less on the day of treatment than in the months that follow.
- 01
Wear the night guard every night
It is the single most reliable protection. Worn for a few days and then left in a drawer, it does nothing.
- 02
Go easy for the first two weeks
The bond is settling. Avoid hard and chewy food during that period.
- 03
Stop tearing with the front teeth
Tearing bread, noodles or seaweed with the incisors sends lateral force straight into the veneer.
- 04
Have the bite rechecked every six months
Teeth drift. If contacts start concentrating on one side, a small adjustment prevents the rest.
- 05
Check in sooner during stressful periods
Grinding intensity varies with life. If your jaw aches, do not wait for the scheduled visit.
Evidence
The evidence behind this page
The judgements above rest on the following long-term follow-up studies.
- 01
Estimated survival 82.9% at 20 years (94.4% at 5, 93.5% at 10)
318 veneers in 84 patients, mean follow-up 118 months. Ceramic fracture accounted for 44.8% of failures, and existing parafunction such as bruxism carried a 7.7-times greater risk of failure.

- 02
Preparations confined to enamel survived at 99% — dentin exposure raised failure risk about tenfold
580 veneers followed for up to 12 years gave 86% overall survival, and 94% when only the margins remained in enamel — what mattered was where the preparation stopped, not merely how much was removed.

- 03
Meta-analysis of 13 studies — 89% cumulative survival (median follow-up 9 years)
Glass-ceramic reached 94% and feldspathic porcelain 87%; complications were fracture/chipping 4%, debonding 2%, severe discoloration 2%, and secondary caries 1%.

FAQ
Frequently asked questions
01 Does grinding rule veneers out entirely?
Usually not — we proceed once the conditions are met: a design that distributes load, and a night guard worn consistently. Where the bite has collapsed or clenching is very heavy, we look at other options alongside.
02 Do I have to wear the night guard forever?
Bruxism does not go away by itself, so we advise wearing it for as long as you have the veneers. Fractures after people stop wearing it are a familiar story in our practice.
03 Would botulinum injections make veneers safer?
They temporarily reduce muscle force and are sometimes used as an adjunct, but the effect is time-limited and it does not remove the habit. It is not a substitute for a night guard.
04 My front teeth are already worn from grinding — can veneers restore them?
Restoring the lost length and shape is exactly what veneers do well. But unless the cause is addressed too, the same wear returns. Our worn-teeth page covers this in detail.
05 Are no-prep veneers better if I grind?
Leaving the enamel untouched is favourable for adhesion. However, no-prep adds thickness to the tooth, which does not suit every case — form and bite are assessed together.
06 If one chips, do we redo only that tooth?
Usually yes. But if the same spot keeps chipping, that is a signal to revisit the occlusal design rather than the tooth.
