You should brush and floss around your crown daily, just as you would a natural tooth. If you grind or clench your teeth while you sleep, you should wear a custom nightguard to protect your crown from excessive forces. You should not bite down on any hard objects, like shells or pen caps, with your crowned tooth, or use your teeth to open packages or bottles. You should also see Dr. Santoro every six months for a check-up, so she can ensure your crown’s integrity and identify any problems early on.
