Fig.8 After the upper left lateral incisor (#10) is extracted, the gums and bone in the root area (*) become very small (ditching in), affecting appearance.  By contrast, the root of the corresponding tooth (* above #7: upper right lateral incisor) is bulging out. This is natural appearance.  We are going to make slices through the teeth #7 and 10 and their roots (long axis) to see how small the bone is after extraction, or return to original article
