Persistent Pain

One of the most obvious signs of a root canal infection is pain that doesn’t go away. While it’s normal to experience some discomfort or mild pain immediately following your procedure, this should gradually diminish over time. Persistent or worsening pain, especially when you bite down or apply pressure to the tooth, could be a sign of infection.

Swelling and Tenderness

Any significant swelling or tenderness in the gums around the treated tooth could indicate an infection. The swelling may not be limited to the gums and can extend to your face or neck, depending on the severity of the infection.

Oozing or Unpleasant Taste

An infection in the root canal-treated tooth might lead to the oozing of pus from around the tooth, which can cause an unpleasant taste in your mouth or bad breath that doesn’t go away with brushing or mouthwash. This is a clear sign that something is not right.

Sensitivity to Heat and Cold

While some sensitivity to hot and cold temperatures can be normal after a root canal, if this sensitivity persists or worsens, it could be a sign of an infection. The tooth should gradually become less sensitive as it heals, not more.

Discoloration of the Tooth

A tooth that has undergone root canal therapy might change color, becoming darker or grayish. This could be a sign of an infection beneath the surface, especially if the discoloration develops well after the procedure.

Boil or Pimple on the Gums

The appearance of a boil or pimple-like lesion on the gums near the site of the root canal is a sign of a recurring or new infection. This pimple may disappear and reappear and can ooze pus, causing a bad taste.

What to Do Next

If you notice any of these signs, it’s important to contact your dentist or endodontist immediately. They can evaluate your symptoms and may take X-rays to look for signs of infection. Treatment for a root canal infection might include antibiotics, draining the infection, or in some cases, a second root canal treatment or surgery.

Prompt treatment not only relieves pain but also helps to ensure that your tooth can be saved. The goal of any follow-up treatment is to eliminate the infection, protect the tooth from future infections, and preserve as much of the natural tooth as possible.

Conclusion

While root canal treatments have a high success rate, being aware of the signs of an infection is key to addressing issues promptly and effectively. Remember, the earlier an infection is treated, the better the outcome for your tooth and your overall health. Don’t hesitate to reach out to your dental professional if you suspect something isn’t right. Your health is worth it.
