What is the purpose of replacing a crown on a tooth with a root canal already done? What are the benefits for my tooth? I thought he might be money-hungry.

If you have decay under your tooth's crown and want to retain or keep the tooth, it will positively require a new crown. If the decay is not treated you will eventually lose the tooth as it will become non-restorable. Once a tooth has had a root canal (and you will never feel any discomfort or pain in that tooth again), it drys out inside, becomes brittle and has lost its primary source of resistence to decay ... that of moisture. Therefore it is imperative that you get this tooth restored sooner rather then later. Your dentist is not money hungry but merely has your best interests at heart. _______________________________________________________________________________ Q: Gold Crown and Floss: I have a gold crown and when I floss the crown it leaves a black stain on the floss.
