**Constant Tooth Sensitivity? Understanding Why Root Canal Therapy is Important for Overall Health**

Constant tooth sensitivity is more than just a minor annoyance — it can be a warning sign that something deeper is wrong. While occasional sensitivity to hot or cold foods is common, persistent or worsening discomfort may indicate nerve inflammation or infection inside the tooth. When this happens, [root canal therapy](https://www.auburn.dental/auburn-al/root-canals/) becomes an important treatment not only for saving the tooth, but also for protecting your overall health.

Inside every tooth is a soft tissue called the pulp that contains nerves and blood vessels. Deep decay, cracks, trauma, or repeated dental work can damage this tissue and allow bacteria to spread. As infection develops, you may notice lingering sensitivity, pain when biting, swelling, or even a small bump on the gums. Ignoring these symptoms can allow infection to move beyond the tooth and affect surrounding bone and tissues.

Root canal therapy removes the infected pulp, disinfects the inner chamber, and seals the tooth to prevent further bacterial growth. This stops the source of infection and relieves discomfort while preserving your natural tooth structure.

Treating dental infection promptly supports your overall health by reducing inflammation and bacterial spread. If sensitivity doesn’t go away, a dental evaluation is the safest next step.
