Wisdom teeth, the last or third set of molars in the back of your mouth may not be removed in the following cases:
- If they are totally healthy
- If they are grown or fully erupted
- Positioned and aligned properly with their opposite teeth
- Are easily cleanable with daily hygiene practices
However, all these cases are very rare to occur or happen. Erupting wisdom teeth can grow at uncomfortable angles in your jaw causing extremely severe pain of swelling.
