If this sounds familiar, you are not alone. Many people experience some type of sensitivity after having teeth filled. According to Nancy Long, a registered dental hygienist and former dental assistant,approximately 15-20% of patients report sensitivity after having teeth filled. Filling teeth involves preparing the tooth (drilling-ugh!) or use of lazers or air-abrasive units to remove active decay. If tooth-colored fillings are to be used ,the tooth is "acid etched" in order to bond the filling to the tooth. Both of these procedures can temporarily aggrevate the tooth, producing sensitivity.
Another reason teeth can become sensitive is due to the size of the decay (cavity) and size of the subsequent filling. A cavity that is close to the nerve will be sensitive before and after filling. Many times your dentist will use a medicated filling to help prevent sensitivity and "calm" the tooth down.
After the tooth is prepared (drilled-there's that word again) the filling is placed and shaped to fit the tooth and fit together with the surrounding teeth. The dentist will make the necessary adjustments by having you "bite your teeth together" for him. Now, because most of the time you have fillings done your mouth is numb, you won't be able to feel if you're biting together correctly. You may experience sensitivity to hot and cold temperatures or find it "hurts" to bite down on something hard. This generally means the filling needs some minor adjustments-so do not hesitate to call your dental office. Your dentist will advise you on what steps need to be taken. A filling that is too "high" can further irritate the tooth and eventually lead to more problems.
Many things contribute to sensitivity after a tooth is filled. Having some slight sensitivity is normal, but when the sensitivity increases, and does not improve within a few days, it is best to call your doctor-you may need an adjustment!
Happy Flossing!
