Worn, short or chipped teeth: veneers, bonding or crowns?

Teeth wear a little with age; that is normal. But when the front teeth have become noticeably shorter, flatter or chipped, the smile starts to look tired, and many people over 50 ask about veneers for exactly this reason. The Oral Health Foundation lists chipped or worn teeth among the things veneers can help with. The important word in any plan for worn teeth is why.

Why teeth wear

The NHS describes teeth grinding as often linked to stress and anxiety, and notes it frequently happens during sleep, so many people do not know they do it. Worn edges are often the first clue. Bring this up with your dentist before any cosmetic plan.

Why the cause matters for your veneers

Veneers do not change the forces that wore your teeth down. Porcelain resists wear better than enamel, but it is brittle: under heavy grinding, it is more likely to chip or crack than to wear. Long-term reviews of porcelain veneers find fracture the most common reason for failure (Alenezi et al., 2021). A clinical study found most fractures and loose veneers occurred in patients with grinding habits, and that a night splint reduced the fracture risk (Granell-Ruíz et al., 2014).

In practice, this means a sensible plan for worn teeth usually includes:

• an examination of the bite and the wear pattern;
• advice on acid if erosion is part of the picture;
• a night guard if you grind, made after the veneers are fitted;
• a realistic amount of extra length, tested with a mock-up.

Small chips: polish or bond

A small chip on the corner of a front tooth can sometimes be smoothed and blended with a polish, with no material added. A slightly larger chip can be rebuilt with composite bonding in one appointment, often without numbing the tooth. Bonding is quick, affordable and repairable. It does pick up stains and lose its shine over the years: a review of composite veneers found about 88% survival over two to eight years, with surface roughness and colour change the most common issues (Lim et al., 2023). For one chip on otherwise healthy teeth, that is often a good trade. See composite veneers.

Teeth worn short: adding length

Rebuilding length is where planning matters most. Longer edges change how much tooth shows when your lips are relaxed, how you say "f" and "v" sounds, and how your top and bottom teeth meet. Too much length looks false and can make you lisp; too little and the change is barely visible.

The best way to judge is a mock-up: a temporary copy of the planned shape placed over your teeth so you can see, speak and smile with it. Our guide to smile design explains this step.

For moderate wear, two approaches are common:

• Composite bonding to rebuild the edges directly. Little or no drilling, easy to adjust, but needs maintenance.
• Porcelain veneers that wrap over the biting edge. The veneer covers the front and the edge, adding length in ceramic. A review found veneers with this edge coverage failed less often than veneers that stopped short of the edge (Alenezi et al., 2021).

Severe wear: when crowns come in

If teeth have lost a lot of structure, especially if the back teeth are worn too and the bite has collapsed, the treatment becomes bigger. Some teeth may need crowns to rebuild strength, and the bite may need to be planned as a whole. This is complex work, and it is fair to expect more appointments, more explanation and a longer plan. It is also exactly the situation where a crown has a clear reason, which should be written in your plan. See veneers or crowns?

Acid erosion: deal with it first

If erosion is part of the cause, a few habits make a big difference whatever treatment you have: keep acidic drinks to mealtimes, drink water afterwards, do not brush straight after acidic food or drink, and see your GP if you have reflux symptoms. Porcelain itself is not damaged by normal dietary acid, but the remaining natural tooth around the veneer can be.

A typical plan for worn front teeth

1. Find the causeExamination, photos of the wear and questions about grinding, diet and reflux.
2. Test the lengthA mock-up to agree how much longer the teeth should be.
3. Choose the materialBonding for small rebuilds, wrapped veneers for moderate wear, crowns only where structure is lost.
4. Check the biteAfter fitting, the dentist checks how the teeth meet in every direction and adjusts high spots.
5. Protect itA night guard if you grind; regular check-ups to catch small chips early.

Living with rebuilt teeth

Teeth that have been rebuilt after wear need a little more respect than untouched ones. Avoid using your front teeth as tools, for opening packets, biting thread or cracking nuts. Cut hard foods such as crusty bread, apples and raw carrots into pieces and chew them with your back teeth. If you play contact sports, wear a sports mouthguard. A laboratory study found that a mouthguard reduced the stress on veneered teeth during an impact, whatever the veneer was made of (Dal Piva et al., 2023).

Most importantly, keep wearing the night guard if one was made for you. Many people stop after a few months because their jaw feels better, and the grinding quietly returns. The guard is cheap compared with replacing a chipped veneer.

What it does to the trip

Bonding repairs are usually done in a day or two. Porcelain veneers for worn teeth fit into the usual one-week trip. If a night guard is part of the plan, it is usually made after the final veneers are fitted, from a scan of the finished teeth, so ask whether it can be ready before you fly or posted on. Our page on the veneers trip shows the typical days.

If only one tooth is chipped

A single chipped front tooth on an otherwise good smile is a special case. Matching one ceramic veneer to natural neighbours is harder than making a full set, and if the chip is small, composite bonding often blends better and costs far less. If the tooth is also darker or heavily filled, one veneer or crown may be the answer. Our article on a single veneer or a full set covers this choice.

Questions to ask

• What do you think caused the wear on my teeth?
• How much length can you add, and will I see a mock-up first?
• Will the veneers wrap over the biting edge?
• Do I need a night guard, and is it included?
• Which teeth, if any, need crowns, and why?

Common questions

Why are my front teeth getting shorter?

Common reasons are grinding or clenching, acid erosion from diet or reflux, and a bite where the front teeth take too much load. Often it is a mix. A dentist can usually tell from the pattern of wear.

Can a chipped front tooth be fixed in one visit?

A small chip can often be smoothed or rebuilt with composite bonding in a single appointment.

Will veneers on worn teeth just wear down too?

Porcelain is harder than enamel and resists wear, but it can chip or crack under heavy grinding. That is why a night guard and a bite check matter.

Can worn teeth be made longer?

Yes, within limits. How much length can be added depends on your bite and how your lips move. A mock-up is the best way to test it.

Is a crown better for a badly worn tooth?

If a tooth has lost a lot of structure, a crown can protect what remains. For moderate wear, a veneer that wraps over the edge or bonding keeps more of the tooth.
