An infected tooth doesn't always result in a toothache. In many cases, the symptoms of infection are much more subtle. You may not even be sure which tooth is infected. Know these signs so you can get to a dentist promptly.

1. Recurring Canker Sores

Canker sores are small red or white sores that form on your cheeks, tongue, or the inside of your lips. A sore can develop for many reasons, and typically they are harmless and clear on their own within a few days to a week. If you have sores that are lasting longer than that, or if they keep coming back, then there may be an infection in your gums or in the roots of one of your teeth.

2. Persistent Metallic Taste

Tasting metal has two common causes, and both indicate something is wrong with your gums or teeth. If you have any fillings, then you may taste metal if the filling begins to fail. If you don't have it replaced promptly, an infection can set into the affected tooth. The other cause is bleeding. Bleeding from the gums around an infected tooth can also result in a coppery, metallic taste in the mouth.

3. Bite Numbness

When you bite down with your teeth firmly pressed together, pay close attention to the sensation. If you have a tooth infection that has damaged the roots and nerves in a tooth, you may have an odd sensation of numbness or pressure on the infected tooth. In some cases, you may sometimes feel pain when biting down, and at other times feel the pressure or numbness. This numb feeling is a symptom of a progressed infection, so you should see your dentist as soon as possible.

4. Gum Bumps

Raised bumps that form on your gums are called abscesses. An abscess is a pocket of infection that fills with bacteria, blood, and pus. It can be small, or it may be large and painful to the touch. You will need to see a dentist so that they can safely drain the abscess and properly treat the underlying infection.

5. Bleeding Gums

Your gums should not regularly bleed. If you experience bleeding gums after brushing or flossing, then there is an infection. Extensive bleeding can indicate periodontal disease or gingivitis, while bleeding from just around one tooth may indicate a tooth infection.

If you experience any of these symptoms, a family dentist can provide services to relieve them.
