There may be some sensitivity and irritation after your visit once the temporary crown is placed and anesthtic has worn out. This is normal and will subside after the soft tissue heals. Rinse with warm salt water ( cup of warm water with a teaspoon of salt) 2 to 3 times a day for the first 3 days. You can also take Advil or Tylenol if the pain does not go away the same day you had treatment. Your temporary crown or bridge is not as sturdy as the permanent one, so you should be careful when cleaning and eating. You should brush and floss the area gently when flossing do not pull up on the tooth instead pull it through in between your teeth. You should avoid sticky or chewy foods while you have the temporary crown. When the permanent crown or bridge is placed it may feel a little awkward for a few days. Your mouth needs to adjust to the new tooth, and it should feel like one of your natural tooth in less than a week. If your bite feels abnormal in any way, let us know as soon as possible so we can adjust it for you.
