Root Canal Questions - 1st one kind of urgent
Any help with these questions would be appreciated, especially with the first one.
1. How long can a back molar go without a crown after a Root canal? I'm going out of town so I'll have to wait for 4 months before I can get my tooth crowned. I'd hate for it to break.
2. My dentist recommends metal crowns (as opposed to porcelain I suppose) for my root canaled molar. But I personally don't like the way it looks. Are there any alternatives or ways to make the crowned tooth look better?
3. In relation to the 2nd question, is a gold crown better than a metal crown? My dentist says the metal crown he's going to give contains a small amount of mercury. Does gold contain mercury too?
