Root Canal
A root canal is a dental procedure performed to treat an infected or damaged tooth. It involves removing the infected or damaged pulp (the soft tissue inside the tooth) and cleaning and disinfecting the inside of the tooth's root canals. The root canals are then filled and sealed to prevent further infection.
Root canal treatment is typically necessary when the pulp becomes infected or inflamed due to deep decay, repeated dental procedures on the tooth, or trauma. Symptoms of a damaged or infected pulp may include severe toothache, swelling, sensitivity to hot or cold, and a pimple on the gums.
During the root canal procedure, the dentist or endodontist (a dentist who specializes in root canal therapy) will first numb the tooth and surrounding area with local anesthesia. They will then create an opening in the top of the tooth to access the pulp chamber and root canals. The infected or damaged pulp is removed using small instruments, and the inside of the tooth is cleaned and shaped. Finally, the root canals are filled with a biocompatible material, such as gutta-percha, and sealed to prevent bacteria from re-entering.
After a root canal, the tooth may need to be restored with a dental crown to strengthen it and protect it from further damage. With proper care, a tooth that has undergone a root canal can last a lifetime. Root canal treatment is often preferable to tooth extraction, as it allows the patient to retain their natural tooth and avoid the need for more extensive dental work, such as dental implants or bridges.
