Endodontics is the branch of dentistry that is concerned with the morphology, physiology and pathology of the human dental pulp and periradicular tissues. Its study and practice encompass the basic and clinical sciences including biology of the normal pulp, the etiology, diagnosis, prevention and treatment of diseases and injuries of the pulp and associated periradicular conditions. In other words, it is the study of keeping your gums and mouth clean.

Endodontics is most concerned with keeping your natural teeth. Sometimes people will have teeth pulled or removed due to an unhealthy gum line. Endodontists specialize in root canals to keep your teeth in your mouth.

Root canal treatment, also known as endodontic therapy, is probably the most maligned of all dental procedures, but the reputation of pain typically associated with "having a root canal" is really not deserved. The majority of people who have undergone root canal treatment typically report that the process itself is no more involved than having a filling placed.

There are many misconceptions surrounding root canal (endodontic) treatment. The American Association of Endodontists wants you to have accurate information. As always, when considering any medical procedure, you should get as much information as you can about all of your options. Your dentist or endodontist can answer many of your questions, and if you still have concerns, it is often wise to seek a second opinion.

Most patients see their dentist or endodontist when they have a severe toothache. The toothache can be caused by damaged tissues in the tooth. Root canal treatment removes this damaged tissue from the tooth, thereby relieving the pain you feel. The perception of root canals being painful began decades ago when root canal treatment was painful. But with the latest technologies and anesthetics, root canal treatment today is no more uncomfortable than having a filling placed.

Nothing can completely replace your natural tooth. An artificial tooth can sometimes cause you to avoid certain foods. Keeping your own teeth is important so that you can continue to enjoy the wide variety of foods necessary to maintain the proper nutrient balance in your diet. Endodontic treatment, along with appropriate restoration, is a cost-effective way to treat teeth with damaged pulp and is usually less expensive than extraction and placement of a bridge or an implant. Endodontic treatment also has a very high success rate.  Many root canal treated teeth last a lifetime.
