With 92% of American adults estimated to be affected by tooth decay, most people can expect to visit a dentist for a filling at some point during their life. But while this safe and effective procedure is extremely common, it’s normal to have questions about the treatment—especially if you’ve never had a filling before. If you’re curious about this dental care practice, here are a few frequently asked questions that patients have about treating a cavity.

4 FAQ About Dental Fillings

Why are fillings important?

Fillings help replace decayed materials to restore the structural integrity of the tooth. When left untreated, oral bacteria will continue to wear away at the tooth and cause the cavity to become larger and more problematic. If a filling is not placed quickly, infection may occur and require you to have root canal therapy or have the tooth extracted.

What happens during the procedure?

The filling procedure can generally be completed in under an hour. After applying local anesthesia, your dentist will use a drill to gently remove all areas of decay while taking care to preserve healthy portions of the tooth.

After a deep clean, your dentist will fill the cavity with a moldable material—such as porcelain or composite resin—that will harden in place. Sometimes, a curing light is used to assist the setting process. Finally, your dentist will shape and polish the tooth.

Do fillings hurt?

Fillings are designed to relieve pain—not create it. Using local anesthesia, your dental care provider will numb the area, so you don’t feel any pain during treatment. Eating carefully and using anti-inflammatory medication can help prevent discomfort directly after the procedure.

If you experience dental anxiety, you can help reduce stress by making enough time for the procedure to avoid rushing, avoiding caffeine before the appointment, and distracting yourself with music or in-office television while you’re in the chair. Your provider might also offer sedatives—such as nitrous oxide—to calm your nerves.

How long does a filling last and how should I care for it?

The longevity of a filling will depend on the material. Porcelain, for instance, lasts up to 20 years, whereas composite may need to be replaced within seven years. To get the most of your treatment, you’ll need to maintain a solid dental care routine that involves twice-daily brushing, daily flossing, healthy food and drink choices, and biannual dentist appointments.
