5 Common Signs You May Need a Root Canal Severe Tooth Pain: Intense, throbbing pain—especially when chewing or applying pressure—often indicates an inflammation or infection deep within the tooth's nerve. Discoloration of the Tooth: A single tooth turning dark grey, brown, or black can mean the internal blood vessels and nerves have died due to trauma or deep decay. Persistent Gum Pimples: Small, raised bumps on the gums (dental abscesses or fistulas) can form near an infected tooth, often draining pus and leaving a bad taste or odor. Gum Swelling: Swollen, tender, or inflamed gums around a specific tooth signal that infection from the root has spread into the surrounding tissue. Prolonged Sensitivity: Lingering pain or discomfort after consuming hot or cold foods and drinks—continuing long after the trigger is removed—points to damaged nerve tissue. Note: If you experience any of these symptoms, schedule an evaluation with a dentist right away to prevent further damage or tooth loss. Are you currently experiencing any of these symptoms yourself?
