Dental recession is the exposure of the tooth root surface. We can talk about a gingival recession when the gingival margin is below the enamel - cement border. This leads to the exposure of the dental root, and thus to its exposure to harmful external factors. The root exposed in this way is characterized by sensitivity and lack of resistance to damage. Teeth covered by gum recession are particularly susceptible to caries. Sagging gums are not only painful dental necks, but also periodontal bone atrophy, which is not well protected and nourished. In some cases, dental recession is associated with pulpitis, and hence the need for endodontic treatment. In the worst case, recession can lead to loosening of the tooth and its loss.
