Root canal treatment becomes necessary when the dental pulp—the soft tissue inside your tooth—becomes infected or inflamed due to deep decay, trauma, or repeated dental procedures. Symptoms prompting the need for a root canal include persistent tooth pain, sensitivity to hot or cold, swelling, and tenderness in the surrounding gums. Without treatment, the infection can spread, leading to abscess formation and potential tooth loss. Opting for a root canal allows you to preserve your natural tooth, maintain your bite, and avoid the complications associated with tooth extraction. With a high success rate, root canal therapy is a reliable solution to alleviate pain and save a tooth that might otherwise be lost..
