怎么保护牙齿的英语作文【一】
这学期我们抓了蜗牛观察，蜗牛很小就看到一个壳还有软软的身体。它喜欢吃青菜，我把它放到青菜叶上，过一会儿去看它，青菜叶少了一个小角。我产生了疑问：蜗牛和我们一样有牙齿吗？如果有，它的牙齿在哪里呢？如果没有，它又是怎么吃叶子的呢？
我仔细观察蜗牛吃叶子的样子，感觉蜗牛就是吞着吃下去的，没有牙齿。妈妈告诉我：“蜗牛本身就是没有牙齿。”我听完妈妈说的话，半信半疑。
后来，我到网上查了一下，原来蜗牛是有牙齿的，但是我们看不见。它的牙齿小得不能再小了。蜗牛不仅有牙齿，而且有成千上万颗。它的牙齿都在舌头上，上面长着无数细小而整齐的角质牙齿，因此它们的牙齿可以达到一万颗以上。所以，蜗牛是世界上牙齿最多的动物。
说到蜗牛的牙齿最多，那它到底有多少颗呢？它的嘴巴大小和针尖差不多，但是它的牙齿有两万五千六百颗牙齿。啊，蜗牛的牙齿真是数量惊人呀！想不到，一张小小的嘴巴，却有这么多的牙齿，我真是不敢相信啊！
我终于知道了一只蜗牛一共有两万五千六百颗牙齿，真是数量惊人啊！

昨天晚上，小鳄鱼金刚睡前吃了一颗糖。半夜的.时候，他的牙齿突然疼起来，一下子从床上滚了下来，躺在地上一直尖叫着，声音大得森林里的每个角落都能听见。
牙医也听见了，他知道这是金刚的叫声，“他肯定是牙疼了。”牙医心想：“我可不想见到他，但是我必见不可，不然我要被扣工钱了。”
天亮了，金刚的牙齿仍然疼痛难忍，他暗暗想到：我可不想去见牙医，但我必见不可，不然我都吃不下饭了，会被活活饿死，要么是被疼死。
于是，金刚大步流星地向牙医家里走去，他刚按响门铃，牙医就透过玻璃门看见了外面的小鳄鱼，他被吓得半死不活，战战兢兢地把门打开，让金刚进来坐在椅子上。
牙医开始工作了，他拿起电钻，刚刚把电钻伸进鳄鱼的嘴里，还没碰到金刚的牙齿，就听见“啊”的一声尖叫，只见金刚迅速地闭上了嘴，死死地咬住了电钻。牙医用力一拔，电钻一瞬间就变成了两截。牙医被吓出来一身冷汗，他只好给金刚打了麻药。牙医用他的钳子迅速地拔出了蛀牙，在金刚合上他的嘴之前，快速拿出了钳子……
牙医摸着金刚的头说：“你以后一定要认真刷牙，不然明年又要来找我了，我可不想再被你咬坏什么东西。”
从此以后，金刚变得越来越勤快了，他牢记牙医的话，每天坚持刷三次牙呢，而且每次都刷得非常认真，再也没有一颗蛀牙了。
