Why Wisdom Teeth Can Cause Problems
Wisdom teeth are the last teeth to come through, usually in the late teens to mid-twenties, and not everyone has all four. Because they come through at the back of the jaw, where space is often limited, they can sometimes emerge at an angle or only partly break through the gum — described as impacted. This can occasionally lead to problems such as discomfort, swelling, or difficulty keeping the area clean.
When Removal May Be Considered — and When It Isn't
An impacted wisdom tooth that isn't causing problems is often simply monitored, rather than removed as a matter of routine. Where a wisdom tooth is causing pain, recurrent infection, or is affecting a neighbouring tooth, removal may be considered instead. This is a decision made through individual assessment, not something this page decides in advance, and removal isn't presented here as something that prevents all future problems.
How This Differs from General Tooth Extraction
This page covers considerations specific to wisdom teeth — including the option of monitoring rather than removal, and the anatomical position at the back of the jaw. For extraction of teeth generally, see Tooth Extraction.
Assessment and Planning
Because wisdom teeth sit at the back of the jaw and can be angled or partly covered by gum, imaging is often used to assess the tooth's position and its relationship to nearby structures before any decision is made about monitoring or removal.
What to Expect in General Terms
Where removal is considered appropriate, the specific approach — including how the tooth is accessed and what, if anything, is used to keep you comfortable — is a decision made individually with your dentist, based on the position and difficulty of the tooth. This page doesn't set out a specific surgical method, sedation approach or referral pathway in advance, since these depend entirely on your own assessment.
Considerations and Limitations
As with any extraction, there are general risks and considerations your dentist would discuss with you individually. Removing a wisdom tooth doesn't guarantee that no further dental problems will occur, and healing varies between individuals. Recovery time isn't stated in general terms here, since it depends on the individual case.
