Q. In the states, the dentist wants to do four root canals and then crowns on the lower 4 front teetch, as they are badly worn from a major overbite. The Costa Rica dentest says why ruin good teeth as the roots are very strong. I understand that porcelin does not do well on dentyn and needs to be on enamil which I don’t have any. He states that a hard composite veneer is better suited on teech with not enamil.,
