龋齿是如何发生的?
龋齿的产生是一个非常缓慢的过程。人们吃的食物中含有糖和各种营养元素,口腔细菌利用它们来分解代谢产生一种,这种酸就会腐蚀牙齿。牙齿的主要成分是各种矿物质,受到腐蚀后慢慢地就会形成一种洞,也就是虫牙。


龋齿应该怎么判断?
我们可以通过色、形、质三个方面来判断是否出现龋齿。
一、色。牙齿表面出现黑褐色斑点、斑块或者颜色变暗
二、形。龋齿发展到一定程度后,牙齿表面会变得不完整,并形成龋洞或缺损


三、质。健康的牙齿质地很坚硬,若牙齿变软或脱钙,就有可能发生了龋齿,很多时候我们需要医生用探针来判断牙齿是否变软了。
当然,牙齿出现黑斑或发黄,也有可能是牙齿清洁不彻底,而不是龋齿。如果自己无法判断是否是虫牙,要尽快就医,以免耽误治疗。
