What Is a Dental Filling and How Is It Done?

A dental filling is a procedure used to repair decayed or damaged teeth and restore their function.

A dental filling is a procedure used to repair decayed or damaged teeth and restore their function. By filling the cavities or damaged areas in the tooth, a filling returns the tooth to its original form and restores chewing function, while also bringing back a natural, aesthetic appearance.

In filling treatment, the decayed or damaged tissue is first removed to create a suitable environment. To ensure the filling is durable and long-lasting, certain techniques are applied to the tooth surface, after which the filling material is placed into the tooth in small increments and hardened with a special curing light. The procedure is completed after bite height adjustment, general shaping, and polishing.

Frequently Asked Questions

Is cavity treatment painful?

Generally, no. Because the procedure is usually performed under local anesthesia, pain is not expected during treatment. Mild sensitivity lasting a few days may occur afterward; this is usually normal and fades quickly.

How many sessions does cavity treatment take?

It varies. Early-stage cavities can often be completed in a single session with a filling, while more advanced cases, such as those needing root canal treatment, may require one or several sessions. The exact number of sessions is determined after an examination and an X-ray.

How long does pain last after a filling?

In most cases it subsides within a few days. With deep fillings, sensitivity may last a little longer. If the pain continues for more than a week, gets progressively worse, or wakes you from sleep, you are advised to see your dentist.
