Your dentist may recommend an extraction in the following situations
A tooth is too badly damaged from trauma or decay to be repaired.
Advanced infection has damaged a large portion of a tooth and surrounding bone tissue.
The tooth is poorly positioned in the mouth (e.g. where teeth are crowded).
A tooth cannot break through the gum (erupt) as there is no room for it in your mouth.
This procedure will be fully discussed and explained depending on your indidual needs.
