Why my crown keeps coming out, what can be done?

crown keeps coming out

1. Crowns keeps coming out because of lack of retention

The number one reason for dental cap keep coming off is lack of retention, and tooth structure is compromised to hold the dental cap. Your crown must have enough retention to stay on the tooth even without any cement. Unfortunately, your crown keeps coming out because the tooth might have been over shaped or prepared aggressively by your previous dentist, period. If there is not much tooth structure left the dental cap keeps popping off, there are possible ways to correct and add to the underlying compromised tooth structure. Porcelain crowns must last a minimum of 10 years.

2. Tooth decay

There could be decay, eating away the tooth structure, and yes a tooth that has been crowned can get a cavity, coming from the root, or possibly all the decays have not been cleaned up.

3.Porcelain crown is not fitting properly

Your porcelain crown fit is not perfect and it is not fitting your tooth properly, causing bacterial microleakage, bad breath, and halitosis.

4. Your Bite

Your bite on the crown is not adjusted, you are putting extra excessive forces on the crown while chewing, and the occlusion on the crown is wrong.

5. Dental cap cemented vs bonded

your dental cap has been cemented vs bonded to the tooth structure, or possibly you have a post and root canal which was not fabricated properly. There is a possibility depending on what kind of crown or cap you have, that you may bond the cap to your tooth vs just cementing, in which bonded restorations are much better than just cement.

6. Dental cap length

Crown to root ratio problem: Your dental cap length and width can not be supported by the root, meaning an unfavorable ratio! also meaning the existing crown is bulkier than your original tooth, if your crown is bulky and the tooth is not prepared properly by the dentist dental cap will exert unnecessary pressure on the tooth causing it either to come off, get loose or possibly damage the nerve.
