Children’s teeth are mostly caries, which can be treated by fillings, extractions and other methods. 1. Fillings:Children’s teeth are usually called tooth decay. If the tooth is decayed, parents should take the child to the hospital stomatology department as soon as possible to check the specific condition of the tooth. If the tooth can be filled, every effort should be made to fill the tooth. If the tooth is in severe pain, it is usually due to tooth residue and plaque attached to the tooth, which affects the pulp of the tooth and requires root canal treatment. 2. Extraction:If a child’s tooth is so rotten that only the root is left, it needs to be extracted. After extraction, if it takes a long time for the permanent teeth to grow out, a gap retainer will be made to prevent the two teeth from growing in the middle, thus affecting the permanent teeth. Children with broken teeth should go to the hospital in time for examination and treatment under the guidance of the doctor.
