Wisdom teeth are also known as third molars. Wisdom teeth do not erupt through the gums until people are in their late teens, twenties or even older and are usually the last teeth to come through the gums. Most people have four wisdom teeth and some people have none. In many people, there is not enough space at the back of the jaws for wisdom teeth to erupt through the gums and if there is not enough space, the tooth will become wedged in or ”impacted”.
Some impacted wisdom teeth remain in place and cause no trouble, whereas other impacted wisdom teeth may cause severe problems. Often one or more wisdom teeth will cause problems and must be removed. If one (or more) of your wisdom teeth causes problems, your dentist may recommend that it be removed.
If your wisdom teeth are likely to be very difficult or complicated to remove, your dentist may refer you to an oral and maxillofacial surgeon.
