Is it possible to put too much glue in a crown when placing it on a tooth? Can it harden and make the crown 'tall'?

There is no need to wait more than the 2-3 days you've waited; if your crown feels high, then you should return to have your bite adjusted.  This is something that takes about 5-10 minutes in the dental chair, but can be easily fix the problem.  If you continue to wait, the tooth will eventually start to hurt.  Good luck and I hope this helps.

Sometimes when a crown is inserted, especially if you are anesthetized, the bite can be off a bit after the anesthesia wears off. We try to check it at the time of insertion with a special bite paper. I would return to your dentist to have it adjusted. It only takes a few minutes.
