Sagging teeth can be treated by orthodontic treatment, using orthodontics to depress the teeth and restore them to their normal position. 1. Sagging teeth are mainly due to the long-term absence of teeth in the opposite jaw, resulting in the loss of normal occlusion and the symptoms of sagging and elongation of the teeth; sagging teeth will mainly cause food blockage and caries and even toothache, and affect the restoration of missing teeth in the later stage of treatment. 2. The better way to treat sagging teeth is through orthodontic traction, the elongated teeth using orthodontic arches or springs to depress the teeth to the normal position; compared with other methods such as grinding away the sagging part of the root canal treatment and then full crown restoration, this method of damage to the teeth is relatively small and does not damage the dental nerve, so it is the preferred way to treat sagging. It is recommended to go to a professional hospital for treatment.
