Biocorrosion: Gum Line Notching and Environmental Damage to Tooth Root Surfaces
A very common condition that many people have is notching or tooth structure loss right above the gum line on some upper and lower teeth. This notching can leave the gum tooth interface unsightly due to discoloration, it can produce sensitivity to hot and cold, and can ultimately compromise the integrity of the tooth structure. This notching is a result of prior gum recession exposing the root surface to the oral environment. Root surfaces do not have the hard enamel covering protecting the tops of the teeth rendering them vulnerable to environmental conditions. Once exposed this surface can be compromised from a combination of chewing forces, acids from the stomach, ...
