When a tooth has a cavity, the decayed part is removed and the space is filled to restore the tooth's shape and function. Leaving a cavity untreated can allow decay to spread.
Tooth-coloured fillings are made from a material that is matched to the shade of your natural teeth, so they are much less noticeable than traditional metal fillings.
After a filling, you will be given simple aftercare advice. Regular brushing, cleaning between your teeth and routine check-ups help keep both the filling and the rest of your teeth in good condition.
