Some parents ask: children’s milk teeth will be lost anyway, do you still need to fill the cavities? We would like to remind you that children with cavities in their baby teeth should go to the hospital actively for treatment, and the earlier the better. Because the cavity is shallow and small, it can be filled once and save time and cost. Otherwise, the cavity will become bigger and deeper from small to shallow. After that, it will invade the nerve of tooth, and the pain will be unbearable, so that the child can’t eat and sleep well, which will directly affect the child’s study and physical health. At this time, it will take several times of follow-up consultation to fill the cavity, and the cost is also high. In addition, the untreated caries can continue to develop and even combine with local infection, causing facial swelling, fever, lymph node enlargement, etc., which will produce adverse consequences. Sometimes the caries of the child is serious, such as only the root of the tooth is left, and also repeatedly red and inflamed, so the bad tooth can only be pulled out. If the baby teeth are missing prematurely due to serious caries, one of them will affect the normal development of permanent teeth; the other one is that the neighboring teeth will be inclined to the gap of missing teeth, which will affect the eruption and arrangement of permanent teeth and cause malformation of teeth and jaws. The serious caries or missing teeth will affect the chewing function of the affected side, resulting in unilateral chewing, which will affect the jaw bone development of the child in a long time, and even the asymmetry of both sides of the face, affecting the facial beauty of the child. In view of the above reasons, if your child has cavities in milk teeth, you should go to hospital to repair them in time.
