Thanks for posting your query,
Temporary crowns or bridges are placed to protect the teeth while the custom restoration is being made. Since the teeth will be anesthetized, the tongue, lips and roof of the mouth may be numb. Please refrain from eating and drinking hot beverages until the numbness
has completely worn off.
Occasionally a temporary crown or bridge may come off.
To keep your temporaries in place, avoid eating sticky foods and candies, hard foods or ice, or chewing gum. It is important to brush normally, but floss carefully and don’t pull up on the floss which may dislodge the temporary.
I hope this information has been both informative and helpful
