Extractions of teeth involve the removal of the crown and root of a tooth. If you require extraction, please discuss all replacement options prior to treatment. If you decide not to replace the tooth, be mindful that in time, teeth may drift into the gap – this may change your bite and chewing ability. Loss of a tooth also concentrates the load onto the remaining teeth.
Please tell the dentist of any medical conditions, medications or allergies. A radiograph of the tooth is always required (by law) prior to extraction to view the roots of the teeth. Today’s anaesthetics are extremely effective in making the procedure as comfortable as possible.
For particularly difficult extractions or some wisdom teeth extractions, referral to a trusted specialist oral surgeon may be required.
OK. So who came up with the name “wisdom teeth?” I mean, they’re anything but wise and often cause problems at the worst possible time.
Wisdom teeth usually erupt between 17 and 25 years of age. There is no “normal” number of wisdom teeth, although most people have somewhere between zero and four. Many wisdom teeth never erupt. Where there is space, wisdom teeth may erupt without incident. However, sometimes wisdom teeth can be difficult.
Why do I need my wisdom tooth/teeth out?
- Limited space: This is the most common reason for removal of a wisdom tooth. Many wisdom teeth start to push through partially, but cannot come through completely. This can lead to a problems and discomfort.
- Persistent infection/pericoronitis: When a tooth partially comes through the gum, it leaves a flap of gum half covering the tooth (called “operculum”). Plaque and bacteria can multiply here and cause pericoronitis – a painful localised gum infection.
- Traumatic bite: Wisdom teeth can often lead to biting of cheeks and gums at the back of the mouth. This can cause continuous ulcers and pain.
- Neighboring damage: This takes two forms;
- Decay: Impacted or crowded wisdom teeth can lead to more plaque, food and bacteria being trapped making the area more difficult to clean. This can cause decay to start between the teeth.
- Resorption: Sometimes the wisdom tooth may partially resorb the side of the adjacent tooth.
- Damage to the tooth: As with any tooth, if a wisdom tooth suffers excessive damage to it from decay, trauma or periodontal disease, it may need to be removed.
- Pathology: In rare cases un-erupted wisdom teeth can be associated with pathology like cysts or tumours.
