Best root canal treatment in kovilambakkam. Root Canal Therapy: Root canal therapy is a safe and common procedure used to save or retain a severely compromised tooth. The dental pulp, which is made up of blood vessels and nerves that provide nutrition to the tooth, is located at the core of your tooth. The pulp keeps the tooth alive. If you notice sensitivity to hot or cold stimuli, discomfort when biting, or swelling, the pulp may have become inflamed or infected. This can be caused by decay, cracks, trauma, deep fillings, or tooth wear. The treatment is intended to remove bacteria from the root canal system and to prevent reinfection. Root canal therapy allows you to keep your natural tooth, promoting normal function.
