If your teeth are sensitive very soon after getting fillings, this is to be expected.

That’s because this naturally sensitive area of the mouth was manipulated by the dentist. Some post-procedure soreness or sensitivity is quite normal.

However, what if this problem persists for days after the procedure? What’s causing this?

“Fillings today are more commonly tooth colored and not the metal fillings that were traditionally placed years ago,” says Donald R. Tanenbaum, DDS, MPH, Clinical Assistant Professor, Dept. of Oral & Maxillofacial Surgery, School of Dental Medicine at Stony Brook University  and author of “Doctor, Why Does My Face Still Ache.”

Dr. Tanenbaum explains, “In the placement process of tooth colored (resin) fillings, there are a number of steps that may cause transient sensitivity.

“This can include the chemical agents that allow for bonding (adhesion) of the resin to the tooth, the drying of the tooth before the filling is placed, and the trauma to the tooth that occurs when cutting the preparation.

“These factors can produce short-term sensitivity of a couple of days and are commonplace.

“Also, a filling that is left a bit high can produce some sensitivity, especially when exposed to cold fluids. This will resolve when the filling is adjusted.”

In the meantime, eat soft foods and avoid cold foods, as well as foods that are typically very hot like soup, rice and the cheese on pizza.
