Not sooo….root canaled teeth tend to be brittle and are much more prone to fracture than “normal” or “live”teeth…They can crack or fracture at any time without warning through no fault of yours and infections can develop through vertical cracks. These cracks or fractures can go from the top of the tooth (crown) through the root and into the supporting bone. Root canaled teeth can also become infected through extra “lateral” canals that are often not seen on x-rays. Gum disease that travels along the side of the tooth can also be a source of infection for a root canaled tooth. Unfortunately, root canaled teeth are a common problem that we see in this office everyday.
