Will Rinsing with Hyrdrogen Peroxide Damage my Crown?

The hydrogen peroxide will not cause any problems with dental restorations (crowns, fillings, etc.).  If your dentist recommended that you use it, I would only use it sparingly in areas where there are periodontal (gum) problems.

Rinsing with hydrogen peroxide will not damage your crown or make metals rust! Follow your dentists instructions and use it as he suggests! I would not do it on a regular basis. Use an alcohol free mouth wash and brush and floss your teeth regularly to keep them free of food particles and bacteria.

No, but don't overdo it......................................................................
