My temporary crown fell off and I can't see my dentist for the next few days, what should I do?

In a pinch, toothpaste helps and has fluoride.  The grocery stores and pharmacies sell cements that are nearly identical to what WE use, so for longer wait times to get back in, those work well.  3 days is a non issue, not much will happen.  All should be fine.One caveat, though, is trapping saliva.  If you simply replaced the temp without a cement or liner, you have trapped bacteria inside.  If you can't brush or rinse, decay can initiate.  If time passes and you don't see a dentist soon enough, there IS risk of damage to the tooth.  Simply putting back and ignoring is not enough.

I agree that it's best to keep your temporary in place.The denture adhesive works well, but a thick paste made from flour and water works as well. Especially if it's only a few days.Sincerely,Dr. Reiser

The temp crown preferably should be on the tooth to prevent shifting.  If the crown stays on when u place it back on that is great but sometimes it can come off too easy.  If the crown keeps coming off you can try getting some denture adhesive from the store, place a very small amount in the crown and press back into place (make sure to wipe up the excess at the gym line).
