A root canal therapy results in the saving of the tooth instead of extracting it. In the past, if you had a tooth with a root tip infection, you’d probably lose that tooth. Through a root canal therapy, now we have an opportunity to save the affected tooth without an extraction. When a tooth is cracked or has a deep cavity, bacteria can enter the pulp causing an infection inside the tooth. Without a proper treatment, an infected tooth can result in painful abscess, swelling, and bone loss. An untreated infection can cause subsequent sinus infections or other severe infections that can spread to other parts of the body. In most cases, a root canal therapy is a relatively simple procedure with little or no discomfort, involving one to two visits. Thus, it is crucial to seek dental care right away if you think or suspect that you might have a dental infection.
