When Is a Root Canal Needed?

Root canal therapy is a necessary treatment when the soft tissue inside your tooth, known as the pulp, becomes infected or inflamed. This is often caused by deep decay, a cracked tooth, or a severe injury. The infection can spread and, if left untreated, can lead to a painful abscess and even tooth loss. You may need a root canal if you experience:

•   Severe, persistent tooth pain
•  Prolonged sensitivity to hot or cold temperatures
•  Swelling and tenderness in the gums near the affected tooth
• A pimple-like bump on the gums
• Darkening or discoloration of the tooth

 What to Expect from Root Canal Therapy

The prospect of a root canal can be intimidating, but thanks to modern techniques and anesthesia, the procedure is no more uncomfortable than getting a standard filling. During your treatment, the infected pulp is carefully removed from the tooth’s interior. The inner chamber is then thoroughly cleaned, disinfected, and filled with a special material to help prevent re-infection. Finally, the tooth is sealed with a filling, and in most cases, a crown is recommended afterward to protect the tooth from future damage and to restore its strength.
