Getting a Root Canal in Los Angles Endodontic treatment, also known as root canal therapy, is a treatment for teeth that have been injured by a big cavity. If the pulp inside the root canal becomes inflamed and infected, dentists may recommend root canal therapy. A root canal dentist in Los Angeles would offer root canal therapy if your tooth is infected. A poorly infected tooth, or one that is likely to get infected, was once destined to be extracted, but nowadays, general dentists and endodontists use a technique known as root canal therapy to save infected teeth. Dentists have been able to recover and save teeth that were previously evicted to ease pain due to the availability of new cutting-edge dental equipment, which is truly a miracle of engineering.
