乳牙迟早要换，坏了不用补……是真是假？| 谣言终结站
一些家长认为“乳牙迟早要换，坏了不用补”，这种观念是错误的。
乳牙出问题，不仅直接影响孩子的咀嚼功能，还可能间接影响营养吸收，进而对身体发育造成不利影响。
同时，乳牙还是恒牙萌出的“向导”。如果乳牙坏掉或者过早脱落，可能会造成恒牙萌出异常，比如萌出位置歪斜、萌出延迟，甚至无法萌出的情况。
此外，一口健康的乳牙有助于儿童正常发音，若乳牙尤其是乳前牙过早缺失或者发生大面积龋坏，会影响孩子发音的准确性与学说话的进程。部分孩子还可能因牙齿外观问题羞于开口，长期可能影响其心理健康。
不少成年人也存在错误观念，认为“缺失一两颗牙齿并不影响进食，无需处理”。
实际上，牙齿一旦缺失，两侧的邻牙会因失去支撑逐渐向空缺处倾斜、移位，与之相应的对颌牙也会因失去正常咬合力约束，向空缺处过度伸长。这些变化容易引发食物嵌塞，进而导致龋坏、牙周病、咬合创伤等一系列口腔问题，严重损害口腔健康。
