If there is enough room, wisdom teeth will usually come through into a useful position and cause no more problems than any other tooth. Often there is some slight discomfort as they come through, but this is only temporary and will disappear once the tooth is fully in position.
If there is not enough room, the wisdom tooth may come through, but will get stuck against the tooth in front of it. The wisdom tooth will be at an angle and will be described by the dentist as ‘impacted’.
If you have pain and discomfort which does not settle, then the best thing to do is visit your dentist.
Persistent or recurrent problems may be best treated by having the tooth removed.
