It is normal to have some sensitivity after a new filling is placed. The level of sensitivity depends on the size and depth of the cavity being filled. Minimizing very hot and cold foods can help with the sensitivity in the first several days.
The composite fillings we place are fully hardened or cured before you leave the office so you can chew normally on these restorations as soon as the anesthetic has worn off.
Please remember to call our office if you have any concerns at all. We are always here to answer your questions.
