A chipped or worn front tooth is one of the most common reasons people ask about composite bonding. Bonding can rebuild the missing part of a tooth with tooth-coloured resin, often in a single visit. This article explains when bonding is a good repair option, how it compares with the alternatives, and what to ask your dentist.

For a general introduction to the treatment, see our complete guide to composite bonding.

Chipped, cracked and worn teeth

Teeth can chip after a fall, a sports injury or biting something hard. Edges can also wear down gradually, for example from grinding. If the damage is small to moderate and the tooth is otherwise healthy, composite bonding can often rebuild its shape so that it looks and works normally again.

See a dentist soon after a tooth chips or cracks, even if it does not hurt. The dentist will check whether the crack goes deeper and whether the nerve has been affected. If a tooth is painful or the damage is large, other treatment may be needed first. If you need to be seen urgently, call the practice and ask for an emergency appointment.

How a bonding repair is done

1. Your dentist examines the tooth, and may take an X-ray to check the damage.
2. A resin shade is chosen to match the tooth.
3. The surface is cleaned, lightly roughened and treated with a bonding agent.
4. The resin is applied in layers and shaped to rebuild the tooth.
5. Each layer is hardened with a curing light.
6. Your dentist checks your bite, then shapes and polishes the repair.

Many repairs take one appointment. A local anaesthetic is not usually needed unless the damage is close to the nerve.

How does bonding compare with other options?

• Crowns cover the whole tooth and are stronger, so they are often recommended for heavily broken or root-treated teeth. They involve removing more tooth.
• Porcelain veneers are more resistant to staining and can last longer, but usually involve removing some enamel and more appointments. See composite bonding vs veneers.
• Teeth whitening changes colour only, not shape. It does not change the colour of existing bonding, so it is usually done first. See composite bonding or teeth whitening.
• Orthodontic treatment such as clear aligners may be better if teeth are crooked or crowded, sometimes followed by a small amount of bonding.

Is bonding right for you?

Bonding may suit you if:

• The damage or change you want is small to moderate.
• Your teeth and gums are healthy, or any problems have been treated first.
• You are happy to look after the bonding and have it checked and maintained over time.

It may be less suitable if you grind your teeth heavily, have a bite that puts a lot of force on the front teeth, or want a large change in colour or position. Your dentist will discuss this with you.

How long will a repair last?

With good care, bonding commonly lasts several years, often quoted as between 3 and 10 years. It depends on the size of the repair, your bite and your habits. Bonding can chip or stain over time, but it can usually be polished, repaired or replaced.

Signs your bonding needs attention

• A rough or sharp edge.
• A small chip or a piece that has come away.
• Staining or dullness that does not polish off with brushing.
• A change in how your teeth meet when you bite.

If you notice any of these, book a check-up. Small problems are usually simpler to put right early.
