Children’s teeth fall out a few months have not grown out may be due to premature loss of milk teeth, which is normal. Special circumstances are congenitally missing permanent teeth, obstruction, shedding of permanent teeth is not normal, it is recommended to go to the stomatology department in time to take pictures for examination and treatment. Premature loss of milk teeth, permanent teeth roots have not yet developed to the degree of eruption, did not reach the root length of more than 1/2, permanent teeth generally do not erupt, this is normal, you can patiently wait for the teeth to erupt. If you have congenitally missing permanent teeth, they will not erupt after the loss of milk teeth, you can take pictures to confirm. If there are multiple blocked teeth or malpositioned permanent embryos that are congenitally inverted, this is an abnormal condition and requires intervention to erupt. In addition, it is necessary to confirm whether the lost tooth is a permanent tooth. If a permanent tooth is lost due to trauma, etc., a new tooth will not erupt in the same position.
