Premolarsare teeth found between the canines and the molars in adults.
There are usually fourpremolarsin the top row and four in the bottom row of teeth.
Premolarshave flat surfaces with ridges, which help in crushing and tearing food.
These teeth often have two points, making them different from the sharp canines and the flat molars.
When people eat,premolarsbreak down big pieces of food before the molars finish chewing.
Withoutpremolars, it would be harder to eat foods like apples or carrots.
前磨牙是成年人犬牙和磨牙之间的牙齿。
通常上下各有四颗前磨牙。
前磨牙表面平坦且有突起，可以压碎和撕开食物。
这些牙齿一般有两个尖头，形状既不像犬牙那样尖，也不像磨牙那么平。
吃东西时，前磨牙先把较大的食物块咬碎，再由磨牙彻底咀嚼。
如果没有前磨牙，像苹果或胡萝卜这样的食物会很难咬断。
