Abfraction teeth are a kind of defect that manifests itself as a violation of integrity of the hard tooth tissues after they erupt. She will receive brighter porcelain crowns later.

This area of enamel is most vulnerable to delamination from the underlying supporting dentin because the enamel shell progresses to a thin "feather-edge" of enamel rods or prisms. The relative dentin abrasiveness (RDA) of toothpastes ranges from the low end of the spectrum, with toothpastes such as Sensodyne's True White (RDA 13) or CloSYS (RDA 53), all the way up to highly abrasive toothpastes such as Crest Pro Health (RDA 155) and Colgate Tartar Control (RDA 165).
