龋病开始时，牙齿质地变得松软。继而出现一个洞，出现刺激痛，继续发展下去就会侵入牙髓，引起自发性痛或夜间痛。病变继续发展可引起根尖周炎等。龋病如不治疗是不会自愈的，因此，要注意预防，如果发现蛀牙应该及时治疗，即“补牙”。
怎样才能防止蛀牙呢？在日常生活中对牙齿的保健就变得尤为重要了。为此，我们应做到以下十方面：
一、选择保健牙刷。值得推荐的是带有柔软圆头刷毛的牙刷，电动牙刷能够消除更多的牙菌斑。
二、选用含氟牙膏。用带有氟化物的牙膏刷牙，能使牙齿釉质变得坚硬，修补失去矿物质的牙齿表面，还有利于阻止牙菌斑的形成。
这就对防护牙齿起到了重要保证
三、借助振动技巧刷牙。先从牙齿内壁刷起，然后再刷牙齿外侧。牙刷要与牙齿以及牙龈成四十五度角，让牙刷振动式运动，从牙根开始，后及全牙，小学五年级作文《作文 假如没有蛀牙》。
四、刷牙不要用力太大。很多人认为刷牙力量越大，刷出牙齿上的污垢就越多，其实不然，力大反而会磨损到牙齿。把牙刷放在家用天平上，用力按，天平显示150克时就是刷牙时的`最大用力。一些电动牙刷会自动限制压力。
五、别忘了睡觉前刷牙。至少在早晨和睡觉前尽可能彻底刷牙，刷2～3分钟。睡前刷牙非常重要，因为晚上产生的唾液较少，口腔里细菌更容易粘在牙齿上。
六、舌头也要一起清理。每天可用舌头清理器或者牙刷清理一次舌面。因为舌面聚集着细菌和食物残渣，它们会导致口臭。
七、使用刷牙辅助器。如果牙龈健康，每周使用两次丝制牙线；如果牙龈萎缩，可用特制的牙线；如果牙缝很宽，就用牙间牙刷。也可以结合自己的具体情况向牙科医生咨询，医生会告诉你使用哪种刷牙辅助器更好。
八、增加唾液。吃口香糖能促进唾液分泌，其含有多种酶和能够修复牙齿表面的矿物质。
九、少吃薯片和爆米花。因为薯片和爆米花中含有丰富的碳水化合物，龋齿细菌能从中获得营养。
十、每半年到医院作一次关于牙齿健康方面的检查
蛀牙英语作文【三】
When I was a freshman in college I watched the film Gua Sha Treatment for the first time, now I am a junior student and I come back to review the movie from a multicultural aspect, I have many different feelings after watching the film again.
At the beginning of the film, XuDatong is given an award and later he delivers a speech. What makes me impressed most is in his speech he says “one day I will become one of you, a truly successful American, today this award proved that America is a true land of opportunity and I am the living proof of that.” At that moment Xu thinks he has realized his American Dream totally with his lovingly wife and adorable son. However, I think it is ironical that to make a speech like that and I assume it is made on purpose to hind a clue for the story's development. How many non—American people have such a beautiful American dream? One of my classmate studies in American now and before he went aboard he told me his American dream is he can stand at the top of the New York. To be honest, I also dream that one day I can get the Green Card living there happily and successfully maybe working at the Wall Street. When Xu gets the award he thinks he entirely melted in the melting pot neglecting the multicultural obstruct, later the plot goes against the way he thinks. And later Quinlan asked Xu'why you be the scapegoat of your father?' Xu answers 'because he is Chinese.' Then maybe Xu knows that there is always a wide gap between Chinese and American cultures.
The second scene is Xu hit his son Denis because Denis hit the son of xu's boss, at the middle of the film xu tells his boss that he hit his own son is only to show his respect to his boss John Quinlan, that time Quinlan feels puzzled “what a Chinese logic”,yes, American can never understand such a logic full of Chinese characteristic, because they respect everyone including the children, they won't beat a child to please the boss, and there is no such a conception of degree between employee and employer, they feel everyone is equal, which is quite different from china.
Connected to the second scene, the third difference I want to analyze is the care for the children. In America, people pay more attention to the right of children which can be seen from the law—leaving children alone at home is illegal, while in China it is so common that almost everyone may experience such loneliness. And Children Welfare Agency does work in America which shows the importance Americans attach to children's right. What's more, I remember a line 'No one won the case, especially the child.' In my opinion, it also manifests the universal concern from the American public to the children.
The fourth aspect is following the procedure, in the film, more than there times, the people focus on the rule, the law, the procedure. At the Christmas Eve Xu wants to return back to his home pretending as a Santa Claus, what a pity, the security recognizes him and persuades 'you are always a good tenement, never causes troubles for me.' And another scene is at the end of the film , the judge says 'I have to follow the procedure.' However, in China people always have to ask for a favor to do something, and later you have to pay back the favor,for myself, I prefer the American style, strict to the procedure.
The fifth and the last point is the humors, Quinlan says 'you can't fall, your health security is the company paid.' 'Datong, welcome home, maybe next time, you can come from the front door.' 'dady, why you come from the window' ' because we don't have a chimney.' I really adore this distinguished American humor, especially in dangerous situations, which is quite rare in China.
That's my whole reaction to Gua Sha Treatment.
蛀牙英语作文【四】
走在大街上，看见小孩子拿着棒棒糖正香甜地咀嚼着，张开嘴巴时，却有许多的蛀牙和牙洞，我想为什么会有蛀牙和牙洞呢？
据我的调查显示：儿童蛀牙病因学说是四联因苏学说，主要包括细菌，口腔环境，牙齿和时间，其基本点为：导致蛀牙的食物（特别是蔗糖和精致碳水化合物）在糖，紧紧贴附于牙面由涎液蛋白形成的获得性膜上，在这种由牙齿表面解剖结构和生化，生物物理特点形成的不仅得以牢固地附着于牙面，而且可以在适宜温度下，有足够的时间在菌斑深厚产酸，侵蚀牙齿使之脱矿，并进而破坏有机质，产生龋。
据我几次反复试验证明：原来，当食物的残渣长时间附在牙齿上。里面的细菌就会对食物残渣进行分解，产生出很酸的物质，然后慢慢地把牙腐蚀成一个个小洞。唾液中的蛋白质、细菌及食物碎属等在牙面上形成一层粘性薄膜，成为细菌生长繁殖的环境，此称为菌斑。食物中的蔗糖分子进入菌斑被细菌利用，可以分解成葡萄糖。这些糖被细菌发酵，产生酸，酸则将牙齿内的矿物质容解，从而发生龋。所以千万别以为小虫子在里面作怪哦！
终于弄懂这一切了，原来蛀牙的发生有一段较长的过程，从初期龋到临床形成龋洞一般需二至五年，因此即使致龋细菌，适宜的环境和易感宿主同时存在。所以以后我们要好好地爱护牙齿，多刷牙，少吃甜酸类的食品，不要让牙齿受到伤害。
瞧吧！只要我们去发现，去追问，小小的蛀牙里竟然蕴含着这么多的学问！我以后一定要努力学习，天天向上，学到更多的知识，以后才能发现更多的奥秘！
