Full Answer

If wisdom teeth develop, they are usually fully formed by age 14. However, most do not start to break through the gums until a person is at least 17. Sometimes there is not enough room for wisdom teeth to erupt. In these cases, the teeth emerge only partially or even remain stuck in the jaw, or impacted. Because of such problems, some people have their wisdom teeth extracted.

  • Q:

    What should you expect when getting your wisdom teeth pulled?

    A:

    In general, a wisdom tooth extraction involves either local or sedation anaesthesia, according to Mayo Clinic. The dental surgeon makes an incision in the gum to extract the tooth. Recovering patients should expect some localized pain and swelling after a wisdom tooth extraction. These symptoms usually last for about two days or up to a week after the operation, notes RCS.
