A small chip on a front tooth can usually be repaired with composite bonding in a single appointment, often without anaesthetic and without removing any tooth. A larger fracture, or one exposing the nerve, needs assessing urgently — and teeth that have worn down gradually need the cause treated as well as the edges rebuilt.
The immediate question is which of those you are dealing with.
If you have just chipped it
- Find the fragment if you can and keep it in milk or saliva. A clean broken piece can sometimes be bonded straight back on, which gives the best possible match because it is your own tooth.
- Rinse gently with warm water.
- If there is bleeding from the gum, apply gentle pressure with clean gauze.
- If a sharp edge is cutting your lip or tongue, cover it temporarily with orthodontic wax or sugar-free chewing gum until you can be seen.
- Avoid biting on it and avoid very hot or cold food and drink.
- Contact the clinic. Even a small chip should be looked at, because a crack can extend further than it appears.
Seek attention the same day if a large portion has broken off, if you can see a pink or red spot in the middle of the broken surface (the nerve), if the tooth is loose or has moved, if pain is severe, or if the injury involved a blow to the face. See dental emergencies.
The repair options
Smoothing and polishing
For a very small chip, reshaping the edge and polishing it may be all that is needed. No material is added and nothing is removed beyond the roughness.
Composite bonding
The usual answer for small to moderate chips. Resin is built onto the tooth, shaped, cured and polished in one visit. Usually no tooth is removed, it costs comparatively little, and it is repairable. It is less resistant to staining and chipping than porcelain over the years — see composite bonding.
Reattaching the fragment
Where you have the piece and it is clean and fits, it can sometimes be bonded back. The match is perfect because it is the original tooth. It is not always possible, and the bond is not as strong as an intact tooth.
A veneer
Appropriate where a larger portion of the front surface is involved, where several teeth are being treated together, or where bonding has repeatedly failed. It requires permanent enamel removal — see dental veneers and veneers versus composite bonding.
A crown
Where a substantial part of the tooth has broken away and there is not enough left to support anything smaller. See crowns and bridges.
Root canal treatment first
Where the fracture has exposed or damaged the nerve, the tooth is treated before it is rebuilt — see root canal treatment. A tooth that was knocked years ago and has since darkened has usually lost its nerve even without an obvious fracture.
Teeth that have worn rather than chipped
This is a different problem and it needs a different approach. Front teeth that have gradually become shorter, thinner at the edge, or slightly translucent along the biting edge are wearing. Simply rebuilding the edges without establishing why will mean the rebuild wears too.
The usual causes:
Grinding and clenching. The most common. Rebuilding the edges is done alongside a night guard and, where the bite is contributing, correcting it — see teeth grinding and jaw clenching.
Acid erosion. From fizzy drinks, citrus, wine, or from reflux. The pattern of wear is different — smooth, shiny, cupped surfaces — and the source has to be identified. Where reflux is suspected, that needs addressing medically as well as dentally.
An edge-to-edge or deep bite concentrating force on the front teeth, which may be why the wear started at all.
Abrasive brushing, which affects the gum line more than the edges but contributes.
Why the bite is checked either way
If a repaired edge takes a heavy contact when you bite or slide your jaw sideways, it will chip again. Checking and adjusting the bite after any front-tooth repair is part of the treatment, not an optional extra.
Frequently asked questions
Will the repair be noticeable?
Well-layered bonding on a single tooth is difficult to spot. It is fair to ask to see the shade checked in natural light before it is set.
How long will a bonded repair last?
Commonly several years on a front edge, less if you grind or bite into hard things with it. It is repairable when it does chip.
Should I whiten before or after?
Before. Composite and porcelain do not lighten, so the shade must be matched to your final tooth colour — see professional versus at-home whitening.
My child has chipped a front tooth. Is it the same?
The principles are similar but a young permanent tooth has a larger nerve chamber and needs assessing promptly. See a knocked-out or broken baby tooth.
Can nothing be done if it is only cosmetic?
Leaving a small chip is perfectly reasonable if it does not bother you and the tooth is sound. Have it checked once to confirm it is stable.
Get it looked at, even if it is small
A chip can extend further than it looks, and worn edges usually have a cause worth finding. See our cosmetic dentistry page.
