回複：我以前有類似問題，現在完全消失。方法非常簡單，請參看以前的帖子（見 link：）

Thank you for the link.  I also use 衝水清牙器 after each meal. (not every time but most of the time). I have tried my best to take care of my teeth, however, still have more cavities. I have measured the PH of my mouth and it is not acidic. Now my son will have brace but orthodontist suggests "interproxmal reduction" which means they will trim very thin layer of the teeth in order to get enough space. That makes me very worried since I am afraid it will damage the tooth  enamel. I don't want him having straight teeth but will have cavity in the future easily. Already paid the deposit for his treatment but still think about to cancel the treatment.

• 個人經驗，對我而言 waterpic 不是主要因素，不用牙膏才是關鍵。其原因那篇 -欲千北- ♂ (23 bytes) () 01/21/2014 postreply 09:50:12

• 隻要早晚都刷，不會變黃。請選用軟牙刷，水溫高一些，並不時含水在口裏。 -欲千北- ♂ (0 bytes) () 01/21/2014 postreply 12:14:19
