There is good evidence that a small-headed counter oscillating electric toothbrush helps in removing dental plaque but they must be used correctly and your dentist or hygienist will advise.

Plaque
牙菌斑
Plaque is a sticky film of bacteria that covers your teeth and gums.
牙菌斑是覆蓋在牙齒和牙齦上的一層頑固細菌。
It develops constantly and you clean it off every day when you brush your teeth.
並會不斷增長，你需要在每天刷牙時清除掉這些菌斑。
Certain harmful oral bacteria feed on the sugars you eat to create acids that destroy the tooth enamel.
你攝入的糖分會“滋養”一些有害的口腔細菌，併產生有害牙釉質的酸類物質。
Cavities are a bacterial infection created by acids, that cause your teeth to experience a hole in them.
齲洞就是細菌侵蝕的表現，酸類物質會導致牙齒上逐漸出現孔洞。
The more sugar you eat, the more acid you will create in your mouth, and the more acidic attacks your teeth are exposed to, the higher the risk of developing tooth decay.
你攝入的糖越多，你口腔裏產生的酸類物質也就越多，牙齒也會隨之遭受更嚴重的酸性侵蝕，造成蛀牙的機率也會更大。
