What you need to know when you have a temporary crown
When you leave your crown appointment, your tooth will be numb and it will have a temporary crown. While your tooth is numb, do not eat anything that you have to chew. After the numbness wears off there are a few things to be aware of. First, the tooth may be cold sensitive, this is normal to an extent. If the tooth is extremely sensitive, or the sensitivity lingers and turns into a toothache, this also should be reported to the doctor. If the temporary crown hits first when you bite down, this also should be reported and is usually easy to correct with a simple adjustment.
The temporary crown is made with temporary materials and is cemented with temporary cement. For this reason you need to be careful that the temporary does not come off or break. The best way to do this is to follow some simple rules. Do not floss around your temporary. Flossing can dislodge the temporary. Do not eat anything sticky like gum, gummy bears, or hard candies. These foods can grab a hold of the temporary and pull it off. Also, hard foods like hard candy, pop corn or raw crispy vegetables may break the temporary crown. It is good to avoid these types of foods entirely.
If your temporary does come off, you have a good temporary cement in your bathroom. You know how the toothpaste gets hard in the bottom of the sink if it is not rinsed clean? It does the same thing in the temporary crown holding it secure, and it has fluoride which helps with sensitivity. If you can clean the cement from inside the temporary crown and put some tooth paste in the crown and bite down for several minutes until it sets up, you can avoid a trip to the office.
