Usually, wisdom teeth removal is not necessary when the wisdom teeth are healthy, fully erupted, can be cleaned easily, they are in a normal position and do not impact other teeth.

However, wisdom teeth extraction is recommended if:

1. The wisdom tooth remains completely hidden underneath the gum. This can cause an infection or a cyst that can cause further issues.
2. If the wisdom tooth is partially erupted. This might cause for some food to be trapped underneath the gum, which can attract bacteria and cause infection. Sometimes cutting the gum covering the partially erupted wisdom tooth can relieve pain.
3. If the wisdom tooth crowds other teeth. This can cause damage to the other teeth.

Your dentist will be able to advise on the best treatment option for your wisdom teeth.
