A wisdom tooth is a third molar that shows up later in life. It can grow completely or impacted. There are people free of any problems with their wisdom teeth, but there are others who suffer from pain and discomfort because of them.
There is no need for wisdom teeth removal if they grow in the right position, meaning they don’t affect the gums, the other teeth or any other part of the mouth. However, if they become impacted and cause a crowding inside, they may have to be removed.
