Tooth-coloured resin shaped onto a tooth to repair chips, close small gaps or change its shape.
What it involves
Composite bonding builds up a tooth with a resin that is shaped, set with a light and polished. It is usually done in one visit and often needs little or no removal of tooth structure, which is why some people consider it a more reversible option than veneers.
Who it suits
Suitable for small chips, minor gaps, slight changes in shape or length and some discolouration that whitening cannot fix. Large changes, heavy biting forces or habits such as grinding can make resin less suitable.
How it usually works
The dentist chooses a shade, lightly roughens the tooth surface, applies the resin in layers and sets each layer with a curing light. The shape is refined and polished. Many people need no anaesthetic. A visit commonly takes under an hour per tooth or small group.
Risks and things to consider
Resin can stain, chip or wear faster than porcelain and may need repair or replacement over time. Results depend on the dentist's skill in shaping. Grinding your teeth can shorten its life, and a night guard may be advised.
Questions to ask before you decide
How long might this last for my bite? What will repair or polishing cost later? Is a veneer or a crown a better choice for my case? Will you adjust it if I am not happy with the shape?
