What are narrow 'slit-like' areas of gingival recession over the roots of teeth called?

Fissures
Clefts
Cavities
Grooves

The correct answer is: Clefts

Gingival recession refers to the process of gums shrinking and moving away from the teeth, exposing more of the root surface. These narrow 'slit-like' areas of recession are called clefts. Fissures are narrow cracks or grooves in the surface of a tooth, typically present in molars. Cavities are small holes or decay in the teeth and do not refer to gum tissue. Grooves are shallow lines or furrows in the surface of the tooth, typically found on the chewing surface of molars. Therefore, the only option that accurately describes the narrow 'slit-like' areas of gingival recession is clefts.
