A baby with a fleshy growth on the gums can undergo an oral examination and have a full-mouth surface tomogram taken. If prolonged gnawing on hard objects causes the fibrous tissue to proliferate and form a thick gingival flap, the proliferated part can be removed under local anesthesia to separate the soft tissue and ensure that permanent teeth can erupt smoothly. If the adjacent space of the milk molar is often filled with food residue and causes alveolar abscess, the abscess can be incised under local anesthesia, rinsed with hydrogen peroxide solution, and applied with iodine glycerin to speed up anti-inflammation. If an acute apical abscess occurs in a milk tooth, the pulp can be opened and drained, the infected pulp removed, the root canal thoroughly cleaned, and disinfectant medication placed. After the inflammation subsides, a calcium hydroxide paste is applied to seal the canal cavity.
