Clinical diagnosis and treatment process, I often encounter some small patients, due to pulpitis caused by apical abscess, inflammation spread to cause intermaxillary infection, parents often say, usually not too concerned about the child’s milk teeth caries, think it’s not a big deal, anyway, milk teeth are also to be replaced, do not need to consult the clinic, but also save a lot of time and money, who knows the consequences of so serious. I really regret it. I think this reflects that our parents’ awareness of the protection of milk teeth needs to be improved, but also reflects that our dental workers do not have enough efforts to educate. Only through the joint efforts of doctors and parents can we save our children from the torment of caries and have a happy childhood. I still want to talk to parents about the importance of maintaining healthy milk teeth. First of all, healthy milk teeth are conducive to normal chewing, digestion and absorption of food. Secondly, premature decay or even early loss of milk teeth will easily cause low self-esteem. Moreover, the chewing of milk teeth can stimulate the development of jawbone and guide the eruption of inherited permanent teeth. Premature loss of milk teeth leads to poor jawbone development and abnormal eruption of permanent teeth, causing crowding of teeth, which affects the aesthetics and is not conducive to the cleaning of teeth. Therefore, it is very important to maintain the integrity of the milk teeth, do not take it lightly, so as not to regret. Jinan Military General Hospital Stomatology Department, Xu Jianzhu
