What does gingival recession refer to?

1. Increase in gum tissue**

2. Migration of the gingival crest away from the crown of the tooth

3. Formation of new gum tissues

4. A dental surgery to reposition gums

The correct answer is: Migration of the gingival crest away from the crown of the tooth

Gingival recession refers to the movement of the gingival crest, or gum tissue, away from the crown of the tooth, leading to exposure of the tooth's root. This condition typically results from factors such as periodontal disease, aggressive brushing, or genetics. When the gums recede, it can lead to increased sensitivity and a higher risk of tooth decay in the exposed areas. The other options do not accurately represent gingival recession. An increase in gum tissue would suggest a different dental condition, possibly related to gum hypertrophy, and the formation of new gum tissues would not align with the definition of recession, which is characterized by the loss rather than the gain of gum tissue. Lastly, while there are surgical procedures that can address gingival recession, this choice describes a treatment rather than the condition itself. Thus, referring specifically to the migration of the gingival crest away from the tooth’s crown captures the essence of gingival recession accurately.
