It is not recommended that children’s large milk teeth be extracted early when they are rotten. Early extraction of baby teeth may affect the growth of permanent teeth or chewing function. It is recommended to go to the stomatology department for filling treatment. Rotten baby teeth are usually caused by caries in children who do not pay attention to oral hygiene and love to eat sweets. It is not recommended to pull out the baby’s big teeth too early. If the caries has not damaged the pulp, it is recommended to go to the hospital stomatology department for filling treatment. Because children’s milk teeth will be replaced, but usually need to be about 14 years old to complete the replacement, such as premature extraction, may affect the growth of permanent teeth and affect the child’s normal chewing function. Early extraction should only be considered if the child is already close to the tooth replacement period or if caries affects the permanent teeth.
