A dental crown or bridge may dislodge and come out. You may be chewing gum, biting down, or even speaking. In this situation, you should hold on to the crown or bridge and contact your dentist without delay.
Why does a dental crown or dental bridge come out? A wide range of causes exist:
- Dental caries: Tooth decay (aka dental caries) may develop where the dental crown or bridge meets the natural tooth structure. A cavity may form underneath, eventually causing the crown or bridge to dislodge.
- Traumatic blow to the tooth: Trauma can knock a dental crown or bridge off the tooth.
- Too much force: Biting forces are extremely strong and can sometimes cause a dental bridge or crown to loosen and dislodge.
- Temporary cement: When a final crown or bridge is being made by the dental laboratory, a temporary one is used in the meantime. This temporary is put in with temporary cement for easy removal when the final one is finished. Thus, temporary crowns and bridges are more prone to come off.
What can you do if you are unable to immediately visit your dentist?
As a temporary solution, you can visit your local pharmacy and purchase dental cement. Clean the inside of the crown or bridge and follow the directions printed on the product. In some products, the cement needs to be mixed, while other cements are activated upon opening. I would like to emphasize that you should dry the teeth as much as possible before using the store-bought dental cement. The longevity of the dental glue drastically increases if the area is dry. Also, you should really try to clean up any excess cement around the teeth after the cement hardens. Even if you do re-cement the crown or bridge yourself, you should still contact your dentist quickly to schedule an evaluation.
