What problems should I be prepared for?

If part of the wisdom tooth has appeared through the gum and part of it is still covered, the gum may become sore and perhaps swollen. This is called ‘pericoronitis’. Bacteria and bits of food can collect under the gum edge, and it will be difficult to clean the area properly.

This is a temporary problem that can be dealt with by using mouthwashes, special cleaning methods and possibly antibiotics. If the problem keeps coming back, it may be better to have the tooth removed.
