Does the pain of an impacted wisdom tooth go away on its own?

Probably yes: After removal of the impacted wisdom tooth.

That depends --: Sometimes it doesn't and things get worse including inability to open your mouth; and sometimes it resolves and then you go through bouts of flare-up and resolution. Best to be seen by your dentist. Hope this helps.

Variable: If there is enough room for the wisdom to come into its intended position, the pain or discomfort will usually subside as it erupts more, but this process may wax and wane. If there is insufficient room for the wisdom tooth, the pain will usually not go away although it may come and go until it eventually does become a serious problem that requires treatment. Your own dentist can evaluate/treat.

Wisdom tooth: If tooth is impacted, it may be causing damage to surrounding teeth/tissues. The presence of pain is an indication that there is a problem. Even if pain subsides surrounding tissues may still be at risk. Have your Dentist or an Oral Surgeon examine and image the area to determine your risk factors and appropriate treatment.
