Shark’s teeth is the correct term for retained milk teeth, which belongs to the category of diseases, generally due to abnormal root resorption of milk teeth, as follows.
1. Shark’s teeth is a common name for “double rows of teeth” caused by retained milk teeth. “Double rows of teeth” refers to the symptom of two rows of teeth appearing in the child’s mouth when the milk teeth have not been lost and the permanent teeth have already erupted.
2. Usually due to the lack of effective stimulation of jawbone development by consuming too fine food, the jawbone is underdeveloped, resulting in the abnormal eruption direction of inherited permanent teeth, and the roots of milk teeth are not resorbed or partially resorbed, so that they can not fall out automatically.
It is recommended to go to the hospital in time when there is a stagnant milk tooth, with the help of the doctor to clarify the cause for targeted treatment.
