So you might wonder, can I superglue my tooth back on if it falls off? This is definitely not a good idea, and if you read the back label of a tube of superglue then you’ll see there are all sorts of dire warnings about the effects of this glue
Purchase Temporary Dental Cement Until You Can Get To Your Dentist
If you can’t get to see your dentist immediately then visit your local drug store to purchase some temporary dental cement. You can mix up some of the cement and use it to temporarily fix your crown back in position, but this is not a long-term solution. It is important to get proper professional dental care as there might have been some reason as to why your tooth fell off in the first place. In addition you are unlikely to be able to re-cement the crown completely accurately, and there is the possibility that bacteria could enter the tooth causing infection and decay.
Dental Crowns Do Not Last Forever
If the tooth was crowned quite a few years ago then it is likely to have reached the end of its life and will need replacing. If the crown is relatively new then it might be possible for your dentist to cement it back in position. If your crown is continually falling off then it could be that there is not enough of the natural tooth left to hold it in position, and your dentist might need to build up the remaining tooth in some way to provide more support for a new crown.
The Consequences of Not Replacing Lost Crowns
Perhaps your crown is in a less visible part of your mouth? If so you might be tempted not to get it replaced or properly re-cemented. This would be a big mistake, and would increase the likelihood of that tooth becoming decayed and eventually needing root canal treatment or even extraction.
When a tooth is shaped for a crown then the protective outer layer of dental enamel has to be ground away to create sufficient room for the crown. Once dental enamel is removed then the tooth will always need to be covered up to protect it from bacteria in the mouth. Dental crowns are designed to form a tight seal around the margin of the tooth. If this seal is broken, or if the crown is removed, then bacteria will be able to attack the unprotected tooth. Why take this risk? It is far better to have loose dental crowns properly sorted out by your dentist than to have to deal with the consequences of losing a tooth.
