Patient Education
These videos — produced by the American Association of Endodontists — explain root canal treatment, specialist care, and common endodontic conditions in plain, easy-to-follow language.
A 3D animated walkthrough of every stage of root canal treatment — diagnosis, anesthesia, accessing the tooth, cleaning and shaping the canals, disinfecting them, and the final seal that protects the tooth. The video shows why a microscope-aided procedure is comfortable, predictable, and almost always faster than patients expect. Watch this before your appointment to know exactly what to expect.
Watch on YouTubeEndodontists complete two or more years of advanced training beyond dental school and focus exclusively on saving teeth. The video explains how their specialized techniques, surgical microscopes, and CBCT 3D imaging produce more reliable outcomes than a general-dentist root canal. It also covers what to ask when your dentist refers you to a specialist.
Watch on YouTubeEndodontists address common patient concerns about root canal safety. The much-quoted claim that root canals "cause disease" originates from a 1920s study that has been thoroughly disproven by modern research. Millions of root canals are performed safely every year — they relieve pain, preserve natural teeth, and are far healthier than extracting and replacing the tooth.
Watch on YouTubeCracked teeth are now the most common cause of tooth loss in adults — and one of the hardest problems to diagnose, because the pain comes and goes and rarely shows on a normal X-ray. The video explains the five recognized types of cracks, the symptoms (sharp pain when biting, lingering sensitivity to cold), and how a specialist uses a microscope and CBCT imaging to confirm the diagnosis. Catching a crack early is the difference between saving the tooth and losing it.
Watch on YouTubeCBCT provides three-dimensional information about teeth and surrounding bone when conventional images are insufficient. Dose depends on the equipment, field, exposure settings, and patient. It is not universally equivalent to a few days of background radiation. Dr. Kung uses J. Morita CBCT for selected diagnostic and treatment-planning questions. Editorial radiation correction, October 18, 2026; this revised statement has not been clinically reviewed.
Watch on YouTubeResorption is the gradual loss of tooth structure caused by the body’s own cells dissolving the tooth from the inside or outside of the root. The video explains the three main types — internal resorption, external surface resorption, and external cervical resorption — what causes each, and which can be treated and which cannot. Early detection (often only visible on CBCT) is critical, so prompt referral to a specialist matters.
