Because temporary dental crowns are just that — a temporary fix until a permanent crown is ready — most dentists suggest that a few precautions. These include:
Avoid sticky, chewy foods (for example, chewing gum, caramel), which have the potential of grabbing and pulling off the crown.
Minimize use of the side of your mouth with the temporary crown. Shift the bulk of your chewing to the other side of the mouth.
Avoid chewing hard foods (such as raw vegetables), which could dislodge or break the crown.
Slide flossing material out-rather than lifting out-when cleaning your teeth. Lifting the floss out, as you normally would, might pull off the temporary crown.
