牙斑会使牙釉质中的钙与磷溶解，形成小洞，这就是龋齿的开始。龋齿对人的健康危害很大，严重者会导致全身性感染。
牙齿腐蚀牙齿开始腐蚀而不加治疗，酸会破坏牙釉质，损伤牙釉质下面的牙质。牙质含有通往牙髓的细小管道，细菌最终会使牙髓发炎。身体此时会产生反应，将更多的白血细胞送往牙髓去对抗细菌。牙齿四周的血管因而扩大，以容纳这些额外的血液及白血细胞。扩大的血管压挤到进入牙齿的神经，造成了牙痛。酸也会进入神经，造成牙痛。这种情况在腐蚀进行到牙质中的神经末梢时会特别显著。如果有大量的细菌侵入了牙髓腔，牙齿的神经可能会死亡，此时即使有白血细胞对抗感染也没有用。到了这个时候，牙痛消失，但却可能导致脓肿。症状在发生腐蚀的初期通常是没有症状的。稍后出现的主要症状，是在吃甜、酸、冷或热的食物时，会有轻微的牙痛。如腐蚀继续下去，口腔中会发出一种很难闻的气味来，这种气味是塞在龋洞里的腐败食物及细菌所造成的。到了腐蚀的最后阶段，牙髓会发炎。如果发生这种情形，在吃了甜、酸、冷或热的东西之后，会发生持续性的牙痛。有时候，会在龋齿上面或下面的颔骨部位发生尖锐的刺痛。
牙齿腐蚀发现得早并及时治疗，一般而言对身体健康不会有严重的危害。但如果细菌从龋齿进入了血液，病情就可能会恶化，甚至有可能导致感染性心内膜炎。而且，如果患有诸如血友病等出血性疾病，在拔牙之前，应先跟医生商量一下。
首先，预防很重要，每天要彻底刷牙，将牙缝里的污垢完全清除掉；少吃糖，少吃点心；使用含氟的牙膏及漱口水，饮用加氟的水；定期去牙医那里洗牙，并做检查。在这种疾病发生的早期，牙医通常会立刻将龋洞清洗干净，并且把它填塞进来。如果腐蚀情况已经很严重，牙医也许会采用一种牙根管手术，将发炎的牙髓组织除掉，并把牙根管填塞起来。在极少数的情况下，医生会将病牙拔除。
1. 注意饮食卫生，少吃酸性食物
2. 平时应该选用含优质摩擦剂的牙膏和保健牙刷，用正确方法刷牙，避免牙齿磨损
3. 如已经有轻度牙齿敏感，可以选择专业的抗敏感牙膏来缓解症状。
建议你平时避免吃一些，甜是酸，是腐蚀牙齿，要注意口腔卫生，饭后漱口，早晚刷牙，多吃一些清淡易消化的食物，不要吃生冷的食物，每个人牙齿情况都是不一样的，可以去医院咨询下医生
