It is not always necessary to remove wisdom teeth that have not caused you any pain or difficulty, but it is possible that could start to give you trouble in the near future as they develop. Thus it is worth having your teeth examined by your dentist so that he or she may give you proper advice about treatment and prevention.
However, it is very common for wisdom teeth to cause problems, and most often these are extracted (removed). Your oral surgeon will remove any gum tissue that might be covering your tooth to access and remove it. After it has been extracted, you might need stiches to close up the wound.
There are some steps that you can take at home in order to reduce the pain and swelling you experience before you have your tooth extracted, such as taking an over-the-counter pain medication, using ice on your cheek, and occasionally rinsing your mouth gently with warm salt water.
