Endodontic therapy is a treatment used to clear your tooth of disease and bacteria that has reached the pulp, which is inside of the tooth. Many people often call this procedure a root canal because the oral surgeon will clean out the roots of your tooth. The pulp of your tooth is underneath the dentin and tooth enamel, which is considered the hardest material in your body. If your tooth is cracked or develops a serious cavity, bacteria can reach this pulp and infect the inside of your tooth. Endodontic therapy is designed to get rid of all the diseased parts of your tooth and prevent any further infections from occurring. Endodontic therapy is very helpful in relieving the pain a diseased tooth can cause, but there are ways to avoid this altogether. Daily brushing and flossing can keep your teeth clean, and visiting your dentist regularly is essential as well. During dental checkups, your dentist can find and repair cracks in your teeth before the bacteria reaches the pulp.
