Children’s dentists will explain patiently, calm the child and gently complete the operation. The structure of baby teeth is characterized by thin enamel and dentin, high pulp angle, and easy to pulp penetration. The professional pediatric dentist will apply chemicals to soften the discolored tooth tissue, use a sharp digging spoon to remove the decayed material and repair the cavity. Since the crown of the baby tooth is short and the filling material is not easily fixed, the pediatric dentist can make a resin or metal preformed crown to restore the anatomical shape of the baby tooth. If the child’s whole mouth has multiple decayed milk teeth and cannot cooperate with the treatment, the treatment can be completed in one time under general anesthesia.
