Hi, Andrew -

My dentist/prosthodontist said to leave them in for 10 minutes (at night, after brushing and flossing) and then not to eat or drink at all after that. He knows some dentists say it's okay to drink water an hour after, but my guy prefers that I don't.

You've gotten a lot of good advice from others here, too. It sounds like everybody does it a little bit differently!
