Canines 犬牙
Canines are the pointed teeth next to the incisors at the corners of your mouth.
Each adult has four canines—two on the top and two on the bottom.
We use canines to help tear and hold food, especially meat or tough bread.
Canines are longer and sharper than other teeth, making them strong tools for biting and tearing.
When you eat tough foods, your canines work with your other teeth to break it into smaller pieces.
If a canine is missing, it can be harder to hold and tear food when you eat.
犬牙是位于门牙旁边、口角两侧尖尖的牙齿。
每个成年人上下各有两颗犬牙，一共四颗。
我们用犬牙帮助撕裂和固定食物，特别是肉类或有嚼劲的面包。
犬牙比其他牙齿更长、更尖，是用来咬断和撕开食物的有力工具。
吃较硬食物时，犬牙会和其他牙齿配合，把食物分成更小块。
如果缺少犬牙，吃东西时咬住和撕开食物会变得更难。
