Low lip ties are commonly seen in young children, and a few are seen in adults, and can be treated surgically. The treatment method is related to age and function. Generally, no special treatment is needed for low upper lip ties in young children under 6 years old; if the low condition still exists after 6 years old and affects normal function, surgical treatment is recommended.1. No treatment needed: If the child is under 6 years old, low lip ties can be observed, and if they do not affect function, no treatment is needed. The labial tether will tend to recede as the child grows older, the alveolar bone will develop, the teeth will gradually erupt, and the position may gradually rise and leave the alveolar ridge to the normal position. 2. Surgical treatment: If the labial tether is still too low when the child is over 6 years old, and it affects the closure of the middle gap between the two newly erupted incisors, it is recommended to go to a regular hospital for labial tethering surgery. If the labial tether is too low, it is recommended to choose whether to have surgical treatment according to the age to avoid the normal function being affected.
