these three types form from a mass of epithelial cells known as the epithelial cuff between the tooth and the mouth.
the gingival epithelium is not associated directly with tooth attachment and is visible in the mouth.
the junctional epithelium, composed of the basal lamina and hemidesmosomes, forms an attachment to the tooth.
this leaves a small potential space between the gingiva and tooth which can collect bacteria, plaque, and calculus.
plaque is a biofilm consisting of large quantities of various bacteria that form on teeth.
if not removed regularly, plaque buildup can lead to dental cavities (caries) or periodontal problems such as gingivitis.
