两侧牙齿均衡进食防龋齿

来源:华人健康网 | 发布时间:2010-12-17 10:53:08 | www.chinesejk.com

有些儿童由于龋齿不敢咬颌或单侧咀嚼等不良习惯,用一侧进食咀嚼。长期用这种方法进食,会使咬颌侧的颌骨和面部肌组织发育,而废用侧上下颌骨发育不良,面部肌肉欠发达,形成一侧脸大、一侧脸小的面部不对称现象。因此儿童必须养成两侧均衡进食的好习惯。

儿童患龋率从1岁开始逐年增高,7岁时达高峰。有些家长认为乳牙能退,不需治疗,到换牙时就好了,这是一种错误观念。儿童龋齿也应尽早治疗,如果发展成根周炎、牙槽脓肿,并反复感染,就会对下方恒牙胚造成影响,使恒牙萌出后牙釉质发育不全,极易患龋齿。
