Can a dentist grind my crown down to adjust its height and my bite?

Hello there,I do not recommend attempting dentistry at home.  There is a reason that your crown came off.  While it is possible that the adhesive failed, other factors include underlying decay. I would recommend scheduling a complete evaluation with your dentist.  Delaying seeing your dentist may cause additional problems. Good luck and I hope this helps.

You may be able to temporarily glue the crown on your tooth but it will not be perfect.  It sounds like the glue that you used has too much of a thickness and you were unable to press/seat the crown all the way down over the tooth.  You need to see your dentist, have the crown removed off, clean off the inside of the crown as well as your tooth and have the crown re-cemented with a permanent dental cement.  If the bite was not high on the crown previously it should not be high on the crown after it is put back on.  

You should talk to your doctor. You might paste it the other way around or in the wrong position. Somethimes is necesary send to make a new one but this depends on how much you put glue and shape.Good luck!
