每天使用含氟牙膏，在家長的協助下刷牙兩次，被證實可以有效地預防蛀牙。
三歲以下的孩子大多還不會自行將口水吐出，因此使用米粒大小的牙膏即可。

在飲水未加氟的地方，例如：台灣，建議使用1000ppm的含氟牙膏。
若是居住地區飲水內有含氟，或您不確定是否含氟，請向您的牙醫師先行諮詢。

Using fluoridated toothpaste twice a day with parents' assistance has been proven to be effective in caries prevention.
Most children under 3 can't spit out water on their own and therefore use only a pea-sized amount of toothpaste.
In countries where fluoride is not added in drinking water, ie. Taiwan, it's recommended to use fluoridated toothpaste containing no less than 1000ppm of fluoride.
In countries where fluoride is added, or if you are unsure, please consult your dentist first.
