Is there a best way to keep a crown glued on to a molar? i think my dentist took out too much tooth structure when giving me a crown recently, and as a consequence the crown keeps coming off. is there some material i can use to make sure it stays on the l

Unfortunately : Unfortunately there is not too much that can be done if a crown keeps falling off despite being permanently cemented. One option is to perform a root canal on the tooth and then use the nerve chamber to anchor a new, larger filling. Once that is done a new crown can be made. The second option is to remove the tooth and place a dental implant.

Therre : Therre are many reasons why a crown might not stay cemented to a tooth including insufficient tooth structure to retain the crown, a crown that does not fit well on the tooth, a weak cement or perhaps some of the tooth broke off inside the crown after it was originally cemented on. I would suggest that you discuss the problem with your dentist as to the reason why there is a problem and what might be the possible resolutions to fix the problem. If you do not get an answer that you are happy with, you might want to go to another dentist for a second opinion.

Conventional : Conventional cements depend on mechanical retention to hold a crown in place. If there is insufficient tooth structure left, cements that bond the crown to the tooth can be effective. Let your dentist know that you are not pleased that the crown keeps coming off and ask for an explanation and a different fix. If you are not hapy with the answers get a second opinion.

More treatment: If a crown keeps coming off, go to a prosthodontist for a second opinion to see what needs to be done to make the tooth properly prepared to receive a retentive crown.
