This patient had gum recession (gingival recession) that exposed the underlying root structure. Enamel is the strongest structure in the body and makes the crown of the tooth. However, the material that makes up the root is not very strong. When we have recession and exposing the root, we can see notching of the root known as "abfraction." This patient was in the beginning stages of abfraction. Along with abfraction, sometimes this recession can cause the teeth to be very sensitive to cold. The before and after photo are three weeks apart and the patient had very minimal sensitivity.
