What is it?
Composite bonding means applying composite resin, a tooth-coloured filling material, directly to the surface of the tooth and shaping it. The material is bonded to the tooth, built up in layers, hardened with a special light and polished.
In most cases very little or no tooth tissue is removed. It can therefore be considered a more conservative option than other covering methods.
Who may it suit?
- Small chips or cracks in front teeth
- Small gaps between teeth
- Short or irregularly shaped teeth
- Stains and limited discolouration
- Wear at the gum line
Extensive loss of tooth structure, severe clenching and grinding or bite problems may make bonding unsuitable. In these cases options such as crowns, veneers or orthodontics are considered together.
How does the process work?
- Examination and planning. The condition of the teeth and your expectations are discussed and the shade is chosen.
- Preparing the surface. The tooth surface is cleaned and prepared for bonding.
- Application. Composite is placed in layers, shaped and hardened with light.
- Finishing and polishing. The bite is checked and the surface is polished.
The procedure is usually completed in a single visit and generally does not require anaesthesia.
Frequently asked questions
Does composite bonding change colour?
Composite can discolour over time with tea, coffee, smoking and similar factors. Regular polishing helps keep the surface shiny.
How long does bonding last?
Durability depends on where it is placed, biting forces and habits. Composite can wear over time or small pieces may chip; in that case it can usually be repaired.
What is the difference between bonding and veneers?
Bonding is done directly in the mouth with composite and usually requires no reduction of the tooth. Porcelain veneers are made in a laboratory and are more resistant to staining, but usually require a thin layer of the tooth to be removed.
What should I watch out for after bonding?
It is advisable to avoid nail biting, chewing pens and biting off hard things with your front teeth. Regular brushing and check-ups continue.
Whether it is suitable for you is determined by an examination.
