Should you remove wisdom tooth if it doesn't bother you?

Consult a OMS. Consult a oral and maxillofacial surgeon. Just because a wisdom tooth does not hurt does not mean its not doing damage to other teeth. You can have bone loss and develop serious infections from wisdom teeth. Consult a oms and radiographs will be taken you can have a discussion about the risk benefits and alternatives of removing wisdom teeth.
Depends. If the wisdom teeth are in a poor position then they should be removed as they could adversely be affecting the other teeth.
