Hello and welcome to HCM Eruption of wisdom teeth causes problem in majority of people due to lack of space in the jaw. They may get impacted or infected. In such case they have to be removed surgically. However, it is not necessary that all people will face problem. People who do not develop these problems can continue without removal. So, removal is done only when the wisdom teeth eruption is associated with symptoms of pain, infection and impaction. Else they can be left as such. Thanks and take care Dr Shailja P Wahal
