A tooth extraction, or exodontia, is the removal of a tooth. Reasons for a tooth extraction include decayed or broken teeth. They may also be removed to make room for other teeth or an orthodontia treatment.
Wisdom Teeth Extractions
Third molars, also called wisdom teeth, are the last teeth to surface, usually between ages 17-25. Most people have four wisdom teeth, some don’t have any, and in rare cases people have more than four. Your dentist observes your wisdom teeth with x-rays as part of regular examinations.
The Canadian Association of Oral & Maxillofacial Surgeons estimates that 85% of wisdom teeth will eventually require removal. Wisdom teeth are often impacted; they do not properly emerge through the gums, instead growing crooked or even completely sideways. Left untreated the impacted teeth can cause many problems including crowding or misalignment of the other teeth and jaw, headaches and infections. Even if not impacted, wisdom teeth can be difficult to clean and may require removal to reduce the risk of decay and infection.
Wisdom teeth extraction is performed under local or general anesthetic and does not require an overnight stay.
