Yes: It is very common to have the tooth change colors because it no longer has a blood vessel. This makes the tooth brittle and easy to fracture so it is a good idea to place a crown over the tooth if it is a back tooth. If it is a front tooth, your dentist can bleach the tooth from inside the tooth. This does not hurt.

Yes: Teeth tend to become darker after root canal therapy. In most cases this is treated with a crown, but sometimes in the anterior it can be bleached.

OLD WIVES TALE: Many years ago when one of the components of root canal cements was silver root treated teeth typically turned black. This is no longer the case.
