Cavities are small holes in the enamel caused by excessive sugar consumption, poor dental hygiene, and cigarette smoking. Once a cavity is formed, it is permanent and can result in tooth loss if left untreated. To protect the health of the affected tooth, dentists will fill the cavity with some form of metal or resin. Following this dental procedure, it is not uncommon for you to experience some pain or sensitivity at the site of the filling. However, if the sensitivity persists, it could be a sign of something more dangerous.

Below, the dental team from Stafford Dental Associates in Stafford Springs, CT, lists some of the most common reasons for sensitivity following a filling, and what you can do to treat it.

4 Reasons Why Your Filling May Be Sensitive

1. Allergic Reaction

Swelling, sensitivity, or pain near the site of your filling could be a sign of an allergic reaction. Allergies to the metals and other materials used in fillings are not entirely uncommon and can be avoided by informing your dentist of them before the procedure happens. If you discover the allergy after the filling, contact your dentist as soon as possible to have it replaced with a different material.

2. Damage to the Filling

If the filling cracks, comes loose, or is pulled out in any way, it will re-open the cavity and expose the inner dentin. This can occur with new fillings, although it is more common among older ones. You may experience persistent sensitivity, and some people can feel the crack with their tongue. Most damaged fillings can be replaced, however, if there is damage to the tooth as well, your dentist may recommend a crown.

3. Nerve Damage

Sharp pain or sensitivity to cold or heat following the placement of a filling could be a sign of nerve damage. This nerve damage could potentially be irreversible, so it is important to seek emergency dental care as soon as possible.

4. You Need a Root Canal

Persistent, throbbing pain which does not go away after getting a cavity filled could be a sign of an infected pulp or damaged nerve root. If you are experiencing either of these conditions, you will need a root canal as soon as possible. The root canal will help stop the pain and save your tooth from further damage.
