Root canal treatment is often necessary when a tooth has a deep cavity, a cracked or broken tooth, or has been injured in a way that has damaged the dental pulp. Symptoms that may indicate the need for root canal treatment include severe tooth pain, sensitivity to hot or cold, swelling or tenderness in the gums, or a discoloration of the tooth.
