牙垢主要是食物残渣、口腔黏膜脱落的上皮、唾液中的粘液素及细菌等混合堆积而成的,它比较软,容易通过刷牙等方法清除掉。牙结石主要是在软垢的基础上加上矿物盐类,如钙盐沉积而逐渐形成的,是附着在牙面上的矿化的菌斑和其它沉积物的总称。它比较硬,与牙齿附着很紧,一般是刷不掉的,必须用器械才能刮除掉。牙石大都是由于口腔不卫生而造成的,多见于不经常刷牙,或刷牙方法不正确者,牙齿排列不齐或因有牙病不敢咀嚼的废用牙。

It is relatively hard, and teeth attached very tight, generally can not afford to brush, you must use the device to scratch off. Most of the dental calculus is caused by unhygienic oral hygiene. It is more common in those who do not often brush their teeth, or who brush their teeth incorrectly, have irregular teeth, or have teeth that they can not chew.
