If the baby’s tongue ligament is rotten, the following measures can be taken to relieve it: 1. The mucous membrane of the tongue ligament can be rinsed with saline, disinfected with iodophor, and sprayed with less irritating anti-inflammatory drugs such as rehabilitative new liquid to speed up the healing, and oral antibiotics if necessary. 2. If the milk teeth have formed deep cavities, the baby should go to the stomatology department for treatment in time. If the milk tooth has formed residual root or crown, it should be extracted as soon as possible to avoid stimulating the lingual tether. 3.After the lesion area is completely healed, the shorter lingual tether can be trimmed under local anesthesia to prevent the recurrence of ulceration.
