Composite fillings are made from microscopic glass particles embedded in a resin. They are used to restore decayed or previously filled teeth. The advantage of composite fillings, as compared with other dental materials, is that they require less healthy tooth structure to be removed to hold the filling in place. This is due to the composite filling’s ability to bond and adhere to the tooth.
Some patients may experience sensitivity to hot and cold temperatures in the newly filled tooth for a few days or as long as a week. If the sensitivity continues beyond that time, please contact your dentist.
