If a tooth is severely broken or decayed, a tooth extraction may be the best course of action.
There are many reasons why a tooth may need extracting. Impacted or misaligned wisdom teeth can cause infection or they can also cause your other teeth to shift which can damage the teeth, gum and bone. In preparation for orthodontic treatment, your orthodontist may recommend a tooth extraction to help reduce crowding. If gum disease is left untreated, periodontal disease can cause a tooth to loosen and extraction will be required.
