Imagine you are enjoying a nice meal when you suddenly notice a strange space open up in the front of your mouth. To your horror, a crown on one of your front teeth has fallen off! Every dental office sees two to three cases like this yearly- as with this patient today. Fortunately, we were able to replace the missing space with a cosmetic Emax lithium disilicate crown. The end result was fabulous- we saved the tooth and improved on the esthetics of the previous crown!
Dental crowns can come loose for a number of reasons. Most commonly, cavities start at the margin between the tooth and the crown and undermine the seal. Once this seal is broken, the crown quickly loses the adhesive and retentive properties that bond it on the tooth. Other common causes of crown loss include trauma, chewing sticky foods and post/core failure.
If you ever lose a crown, do NOT try to re-cement it (even using temporary crown cement from the drug store). You run the risk of creating a bond so strong that the dentist cannot remove it without damaging the tooth or a bond so weak that it causes the crown to become a choking hazard. Rather, call our office as soon as possible and let us know what happened. Depending on how the crown fell off, what was underneath the crown and if there was any damage to the tooth we may be able to recement it with little modification.
Unfortunately, there is no way for us to determine if the crown or tooth is savable over the phone. Your best bet is to schedule an emergency appointment at your earliest convenience. The longer your tooth stays exposed without a crown, the more likely it is to become damaged through daily use. If you would like to know more about lost crowns and how to protect your teeth, please give our office a call!
