一出生就有牙是怎么回事？
有些宝宝一出生就长牙，称为“诞生牙”，还有些宝宝出生30天内萌出乳牙，称为“新生牙”。“诞生牙”和“新生牙”往往出现在下颌前牙。由于牙根尚未发育或者牙根发育很短，这种牙特别松动，如果摇摇欲坠者就有误吸入呼吸道的风险，还有些会摩擦舌系带导致深大溃疡，影响小婴儿吃奶，常需要拔除，应尽快带宝宝到医院就诊，由医生判断治疗方案。
专家提醒
河北省儿童医院中西医结合院区口腔科副主任郝庆慧提示家长，保护口腔健康，要从娃娃抓起。从孩子出生的那刻起，口腔健康保卫战就已拉开帷幕，“长牙”则是这场持久战中的第一场战役。从第一颗乳牙开始，家长应帮助孩子养成良好的口腔习惯，树立正确的健康观念，为孩子未来的口腔健康打下坚实的基础。
