Teeth that have root canals can fracture more easily than other teeth because they are weaker and somewhat dehydrated. They can sometimes be as brittle as glass. In the past the best available treatment was to remove the tooth and file down the adjacent teeth and make a bridge – caps on the adjacent teeth with an attached “dummy” tooth in between. Sometimes this still is the only way. However, in many cases an implant can replace the fractured tooth and no teeth need to be ground down at all.
