The Truth About Tooth Infections

October 1, 2024

Is my tooth infected?

A tooth infection, also known as a dental abscess, can cause a range of symptoms like pain, tenderness/swelling, sensitivity, fever, or bad odor. If you experience any of these symptoms, it’s crucial to promptly seek care from your trusted dentist to prevent the infection from spreading and causing more serious complications.

How do teeth get infected?

A tooth can get infected anytime it’s exposed to bacteria for a prolonged period of time, typically after experiencing damage or tooth decay. A tooth infection can also develop due to:

Cavities: Diets high in acid and sugar, or ineffective oral hygiene can cause plaque buildup leading to cavities. If left untreated, the bacteria from the tooth decay will reach the tooth’s innermost layer and cause an infection.
Trauma or Injury: Accidents or injuries to a tooth (like from a fall) can cause severe damage. If damage to the tooth leaves the pulp exposed to bacteria, you could be at risk for an infection.
Periodontal Disease: Periodontal disease is an infection that causes bleeding and inflammation of the gums. As the disease progresses, the infection can reach the bone and tooth roots and cause an abscess.
Failed Restorations: Over time, dental restorations like fillings or crowns, can loosen, allowing bacteria to infect the tooth.

How are tooth infections diagnosed?

If you experience the symptoms of a tooth infection, like pain, tenderness, swelling, sensitivity, or bad odor, you should visit your dentist as soon as possible for a thorough evaluation. During your evaluation, you’ll have an opportunity to discuss your specific symptoms with your dentist.

To determine if the tooth is infected, your dentist will likely:

Visually inspect the tooth and supporting structures for redness, swelling, or a visible abscess.
Tap and press gently on the tooth to test for sensitivity, tenderness, and pain.
Apply heat or cold to the tooth to test the sensitivity of the tooth’s nerve.
Review a series of dental x-rays that reveal a detailed view of the internal components of the tooth and jawbone.

What’s the process for treating a tooth infection?

Tooth infections are treated based on the severity of the infection. An antibiotic may first be prescribed to reduce the infection and prevent it from spreading. Then, your dentist may recommend treatment options such as root canal therapy and a dental crown, or a tooth extraction with a dental implant.

In the case of root canal therapy, your natural tooth is saved. The infected pulp inside the tooth is removed and the root canals are filled and sealed. Depending on the complexity of the situation, this procedure may need to be referred to a root canal specialist, also known as an Endodontist.

Alternatively, if the tooth is too damaged to be saved, your dentist may recommend a tooth extraction. Once the extraction site has healed, an implant and dental crown may be placed to restore the function and appearance of your smile.
