What does it involve?
The decayed tissue is removed, the cavity is cleaned, and the shape of the tooth is rebuilt with a tooth-coloured restorative material.
The filling is then adjusted to your bite and polished, so that chewing feels comfortable and the surface stays smooth.
When is it recommended?
Signs that justify an appointment:
- a dark spot or visible cavity on a tooth
- sensitivity to sweet, cold or hot
- food repeatedly catching in the same place
- an old filling that is cracked or has come out
What to expect
Treatment is usually carried out under local anaesthetic so the procedure is comfortable. Mild sensitivity in the following days can be normal and gradually settles.
Frequently asked questions
Does a small cavity need treating straight away?
An early lesion can sometimes be monitored and controlled with preventive measures. The decision follows a clinical examination.
How long does a filling last?
It varies with the size of the restoration, chewing forces and oral hygiene. Regular check-ups help detect wear early.
Is treating a cavity painful?
With local anaesthetic the procedure is generally pain-free. You may feel pressure or vibration, but not pain.
