I had a gold crown placed in Nov., then had a root canal 2 weeks ago because of increasing pain (but no infection). Seems to be successful so far. Should I get my gold crown replaced or just get an amalgam filling? I am concerned about the amalgam filling eventually leaking, especially since I grind my teeth. However I'm also concerned the tooth will be damaged during crown removal. Which risk is greater: amalgam filling leakage, or tooth damage during crown removal? Cost is not a problem.
