I have a molar (#18) on lower left side of jaw whose side was broken off (half of the inside facing side extending to half of the front end) to below the gum line, exposing the filling which also goes below the gum line. It does not hurt and I have an emergency appointment to have it pulled within 24 hours. There was no decay involved, the tooth material over the metal filling was thin. Can that kind of injury be saved with a crown if that can be done quickly?? I want to avoid the risk of infection, so I'm not going to wait past tomorrow.
