Tooth neck defects can develop for a range of reasons. In our opinion, one of the main factors is that teeth bend under severe functional stress, which has been shown in studies. Simultaneously, the tooth enamel begins to become thinner and anamorphically structured, meaning that there is no longer an equally distributed crystalline structure. This leads to tooth neck defects in these areas and increased sensitivity or susceptibility to carries, which requires treatment.
The stress placed on the tooth through bending causes fracturing and loss of the tooth enamel. This exposes the soft and sensitive tooth pulp below. This leads to the development of tooth neck sensitivity and cuneiform (wedge-shaped) defects above the gum margin. Inlays can be used to cover the tooth necks without the tooth having to be fitted with a crown. Our experience has shown that the progression of tooth neck defects, which are often somewhat incorrectly referred to as “cleaning defects”, and the subsequent gum loss on the visible tooth surface can be halted using tooth neck inlays. The preservation of the attached gingiva ensures the joining of the gums to the tooth neck as well as the structural preservation of the bone below. This inhibits the development of bone and gum recession and the corresponding gingival pockets without the need for surgical intervention.
