Filling a tooth – what happens
A tooth may need a filling if it has a cavity, has been damaged or has an existing filling that has broken. Small areas of decay do not always need a filling. The dentist assesses which treatment is needed.
Examination and anaesthetic
The tooth is examined first. Sometimes X-rays are needed. Tell the dentist if you are anxious or have previously reacted to a material. You can be given an anaesthetic before treatment and should speak up if you feel uncomfortable.
The tooth is prepared and filled
The dentist removes damaged tissue and tries to preserve as much of the tooth as possible. For deep cavities, some of the damaged tissue closest to the inside of the tooth may be left under a well-sealed filling. This is an established treatment method chosen following an assessment.
Composite is a common tooth-coloured filling material. It is attached with a bonding agent and usually hardened with light. The filling is then shaped and polished, and the dentist checks how it fits your bite. For more extensive damage, a crown, for example, may be more suitable.
After treatment
Be careful when chewing until the anaesthetic has worn off so that you do not bite yourself. The tooth may feel sore or sensitive for a while afterwards. Contact your dental clinic if the symptoms get worse, do not go away or if the filling feels too high.
Keep brushing with fluoride toothpaste and cleaning between your teeth. A filled tooth needs the same daily care as your other teeth.
