Got 2 teeth needing attention. Dentist says she won't know till going in, but they'll either need a root canal, a crown, or extraction. Not worried about the crown, but got some feedback today regarding the canal and how bacteria can gather "underneath" which goes to the heart (I sometimes wonder what condition my heard is in already). I think of just asking her to pull them, but I thought that messed with teeth alignment?

Any feedback?

Also how do things like Bactrim feed into such things as crowns & canals - prior & post?
