A root canal procedure is used to save a ‘dead’ tooth from infection or damage caused by decay, dental procedures, or tooth trauma. Signs you may need a root canal include pain, sensitivity, tenderness when chewing, swelling, and tooth discoloration. The procedure involves numbing, removing the infected pulp, cleaning, and sealing the tooth, and finally placing a crown or filling on top. Temporary sensitivity may occur, but recovery usually takes a few days. Root canal procedures are typically comfortable and have a success rate of up to 95%, with long-lasting results. Root canal therapy is a great option to save your natural teeth, which would otherwise have to be pulled out and need replacement in the future.
