Tooth extractions or tooth removal is necessary when a tooth becomes so heavily broken down or mobile due to gum disease or tooth infection. They are the least preferred option and last resort treatment for an unsalvageable infected tooth. Local anaesthetic is used for your comfort to make the experience more pleasant.
Wisdom teeth or third molars are the very last teeth in your jaws. Individuals can have up to four wisdom teeth but can also vary by having none, one, two or three wisdom teeth. They usually appear between the ages of 17-25.
Removal of wisdom teeth is required if they are prevented from erupting properly. This means that the wisdom teeth may be growing sideways, into the tooth in front, partially under the gum or even fully submerged under bone. These can potentially cause problems such as bacteria/plaque build-up, swollen gums, cause decay to the adjacent tooth and in some cases, development of cysts.
Most wisdom teeth can be removed at the dentist but for more difficult cases, patients may require referral to an oral surgeon.
