Crowns and bridges are needed to be bonded to supporting teeth underneath. From time to time, these crowns and bridges may fall out for one reason or another. Though most of the time people don’t experience any level of discomfort when this happens, the significant size of the restorations can dramatically impact the way your mouth feels and functions. The reasons these supports may fall out are usually due to new decay under or around the crown or bridge.
Even though crowns cover a majority of the tooth above the gum lines, there is still an exposed surface area along the margin of the crown. This means food, bacteria, acids, and decay-causing microorganisms can cling to the tooth; if the tooth is not properly cleaned every day, new cavities are sure to develop. These small cavities expand deeper into the tooth, causing it to decay to the point where there is nothing left for the crown to adhere to.
When a crown or bridge falls out, it’s important to save the restoration. Keeping it in a zip bag is adequate and can keep you from losing it before you can get to your dentist.
Be sure not to forget to bring your crown or bridge with you in case it can be bonded back into place. Your dentist will check the structure of the supporting tooth to see if it is sound enough to continue supporting the restoration. When at all possible, your dentist will simply cement the crown or bridge back where it was. If the supporting teeth are not stable enough, your dentist will most likely recommend re-treating the area with a new restoration or offering another type of tooth replacement.
