Cavity fillings
Treating a cavity early by removing the decay and restoring the tooth with a filling.
What it is
A cavity is damage to the tooth caused by bacteria and sugar. The dentist removes the decayed part and fills the space with a suitable material, often the colour of the tooth. Treating a cavity early is usually simpler and helps keep your natural tooth.
How it usually goes
- 1The dentist locates the cavity, with an X-ray if needed.
- 2The area is numbed with a local anaesthetic.
- 3The decayed part of the tooth is carefully removed.
- 4The tooth is filled and shaped to fit your bite.
Frequently asked questions
Will I feel the treatment?
The area is numbed beforehand for your comfort. Tell the dentist at any time if you feel something.
Can a cavity go away on its own?
No, once a cavity has formed it needs treatment to stop it progressing. Early treatment is usually simpler.
What if the cavity is deep?
A deep cavity sometimes needs root canal treatment or a crown. It depends on your situation; the dentist explains the options at the consultation.
