Hi, the best treatment for a wisdom tooth problem is to get them removed. There is no point in having the wisdom tooth treated by root canal
because of the following reason:
1. Reach/access: since wisdom tooth is the last tooth in the mouth, the reach or access for the dentist
is very difficult. Because of this the instrumentation may not be proper.
2. Anatomy: the structure of the wisdom unlike other teeth is in most of the cases malformed. It becomes very difficult for the dentist to assess the number of canals and the root canal treatment
may go for a failure.
3. Crown: again due to inaccessability it is very difficult for us to put a cap or a crown onto it. Probably the reason why your dentist has done a silver filling. I would suggest that you get your wisdom teeth
