A root canal is needed when the inner pulp of the tooth becomes infected or inflamed. This infection cannot heal on its own and, if left untreated, can lead to severe pain, abscess formation, or even tooth loss.
Common Reasons You May Need Root Canal Treatment
Deep tooth decay reaching the nerve, Severe or untreated cavities, Cracked or fractured teeth, Repeated dental procedures on the same tooth, Trauma or injury to the tooth, and Long-standing sensitivity or pain.
Root canal treatment is a safe, effective procedure that removes infected pulp, cleans and disinfects the tooth from the inside, and seals it to prevent future infection.
Tooth pain usually occurs when bacteria enter the pulp (the soft tissue inside the tooth containing nerves and blood vessels).
Causes of Root Canal–Related Pain:
Infection inside the tooth, Pressure buildup due to inflammation, Nerve damage or irritation, Swelling around the tooth root, and Abscess (pus formation).
