Why does it hurt under your tongue after root canal?

It is uncommon for patients to experience pain underneath their tongue after a root canal. However, there are a few potential causes of this discomfort:

- Residual inflammation: After a root canal, there can be some residual inflammation in the area around the treated tooth. This inflammation can cause pain or tenderness in the surrounding tissues, including the tissue underneath the tongue.

- Nerve irritation: During the root canal treatment, the dentist may have inadvertently irritated a nerve near the treated tooth. This irritation can also lead to pain or discomfort in the area underneath your tongue.

- Infection: In some cases, a bacterial infection can develop in the area around the treated tooth. This infection can cause pain, swelling, and tenderness in the surrounding tissues, including the tissues underneath your tongue.

If you are experiencing pain underneath your tongue after a root canal, it is important to see your dentist as soon as possible. They can determine the cause of your discomfort and recommend the appropriate treatment.
