Repair of decayed or damaged teeth with tooth-coloured composite or other filling materials.
What it involves
A filling replaces tooth structure lost to decay or damage. The dentist removes the decay, cleans the cavity and fills it with a material such as composite resin, glass ionomer or, less often today, amalgam. Tooth-coloured materials are most common.
Who it suits
Suits teeth where the damage is limited and enough sound tooth remains. Larger cavities may need an inlay, onlay or crown instead. Very deep decay can require root canal treatment.
How it usually works
Local anaesthetic, removal of decay, cleaning, placement of the filling in layers and a light to set the material. The dentist shapes it and checks the bite. Most fillings are done in one visit.
Risks and things to consider
Teeth can be sensitive for a short time afterwards. Fillings can leak, chip or wear and decay can start again at the edges. Deep fillings may irritate the nerve and later need root canal treatment.
Questions to ask before you decide
What material is used and why? Would a larger restoration be wiser for a tooth this damaged? What follow-up do you suggest?
General information, not medical advice. A dentist decides what suits you after examining you.
