If the gum recession is caused by the pressure of calculus, it can be restored after removing the calculus. However, if the gum recession is caused by the resorption of the alveolar bone due to calculus, it cannot be recovered in general. For patients with gum recession caused by calculus pressure, diligent brushing, reasonable diet, ultrasonic scaling and scaling can be used to remove calculus and relieve the pressure of calculus on the gums, thus promoting the recovery of gum recession. If brushing and scaling cannot get rid of calculus, tartar dissolution treatment is also available. If calculus leads to periodontitis, alveolar bone resorption, and severe gingival atrophy, the gums cannot recover even after getting rid of calculus, lateral gingival flap transfer or free gingival flap transplantation can be taken. If the teeth have related complications such as dentin sensitivity and wedge-shaped defect, symptomatic treatment is also needed. In addition, it is important to learn to prevent the occurrence of calculus in ordinary life so as to avoid the appearance of gingival recession. Pay attention to maintaining oral hygiene, brush your teeth in the morning and evening, rinse your mouth after meals, and drink more water. If there is a small amount of calculus on your teeth you can use dental floss and other utensils by yourself and carefully remove it. If there is more calculus, you need to go to a regular dentist for scaling.
