The lower permanent incisors erupt to the tongue side of the baby incisors. What to do?
A. The most common abnormality (not to worry about) is the lower incisors erupting to the tongue side of the baby incisors, or the upper incisors erupting in front of the baby incisors. Usually just waiting six months solves the problem. Typically the retained baby teeth loosen and fall out. The permanent tooth erupts vertically enough to become a “paddle,” pushed into position by the natural forces of the tongue and lips.
