The root canal is the innermost passage of a tooth, the space in between its pulp and roots. Due to damage, disease, or decay, this space can become infected. To preserve the tooth and prevent further spread of infection, a dentist will need to remove the affected nerve. Here are four indicators you need this service.

How to Tell You Need a Root Canal

1. Darkening of the Tooth

When the infection spreads in the root canal, it cuts off the blood supply, ultimately causing the tooth to die. Thus, you may notice a single tooth beginning to darken in appearance.

2. Sensitivity to Coldness & Heat

Many people have some sensitivity to cold foods such as iced drinks and ice cream. But if you experience severe discomfort when coldness comes into contact with a certain tooth, bring it up to your dentist. Sensitivity can also occur with hot foods and drinks. Take note of any aggravation when you’re sipping your tea or coffee. Worsening sensitivity is a common sign of an infected tooth nerve.

3. Tenderness at the Gum Line

Are you experiencing tenderness along a section of your gums? While this could also be attributed to a variety of conditions, such as gingivitis, it may also be an early warning sign of infection.

4. Swelling

Swelling may occur near the infected tooth. If you experience swelling of the soft tissue, including the gum line, surrounding a tooth, which cannot be explained by an injury or preexisting condition, contact your dentist. In the meantime, as long as your teeth aren’t too sensitive, eat some cold foods, such as frozen grapes, to relieve discomfort.
