Epic in scale and intimate in approach, White Teeth is an ambitious novel. Genetics, eugenics, gender, race, class and history are the book's themes but Zadie Smith is gifted with the wit and inventiveness to make these weighty ideas seem effortlessly light.

The story travels through Jamaica, Turkey, Bangladesh and India but ends up in a scrubby North London borough, home of the book's two unlikely heroes: prevaricating Archie Jones and intemperate Samad Iqbal. They met in the Second World War, as part of a "Buggered Battalion" and have been best friends ever since. Archie marries beautiful, buck-toothed Clara, who's on the run from her Jehovah's Witness mother, and they have a daughter, Irie. Samad marries stroppy Alsana and they have twin sons: "Children with first and last names on a direct collision course. Names that secrete within them mass exodus, cramped boats and planes, cold arrivals, medical checks."

Big questions demand boldly drawn characters. Zadie Smith's aren't heroic, just real: warm, funny, misguided and entirely familiar; reading their conversations is like eavesdropping. A simple scene, Alsana and Clara chatting about their pregnancies in the park: "A woman has to have the private things--a husband needn't be involved in body business, in a lady's ... parts."

Samad's rant about his sons--"They have both lost their way. Strayed so far from what I had intended for them. No doubt they will both marry white women called Sheila and put me in an early grave--acutely displays "the immigrant fears--dissolution, disappearance" but it also gets to the very heart of Samad.

White Teeth is a joy to read. It teems with life and exuberence and has enough cleverness and irreverent seriousness to give it bite. --Eithne Farry --This text refers to an out of print or unavailable edition of this title.

査蒂査蒂·史密斯（Zadie Smith 1975— ）当代英国最具影响力的作家之一，奥兰治（Orange）奖得主,入选2003年英国著名文学杂志《Granta》10年评选一次的“英国20位最佳青年作家”。在多族裔混居的北伦敦长大，父亲为英国白人，母亲带有牙买加黑人血统。

査蒂6岁就开始写诗，创作短篇小说。不过，她童年时的梦想并不是当作家，而是做跳踢踏舞的舞蹈家。

中学时，査蒂似乎不是那种有远大抱负的好学生。她把绝大部分课余时间都用在阅读和交友上，还抽过大麻。当她告诉老师自己想申请剑桥时，老师直接告诉她这想法太荒谬，太不切合实际。然而，她果真如愿来到了剑桥大学研究英语文学。在剑桥国王学院，她整天沉浸在小说的世界里，从她喜爱的作家如福斯特、塞林格和冯内古特那里学习写作的技巧和审美情趣。上高中和大学时，她还曾靠在酒吧做爵士乐歌手打工赚钱。

在剑桥读书时，査蒂遇到了尼克査蒂·赖尔德。赖尔德当时正在研修诗歌并且编辑诗集。两人于2004年结婚。

査蒂·史密斯是一位喜欢挑战正统的个性作家。她的这一性格从年少时改名一事就已显露出来。她原来叫Sadie，14岁时自作主张改成了Zadie，在英语中，S音更柔和，而Z音则响亮些，更有个性，也更有异国情调。

当所有人都对査蒂的处女作《白牙》叫好的时候，有一个人却在“阴阳怪气”地说，这部作品出自少年老成、故作姿态者之手，“书中一些片断如杂草丛生，不堪一读。”这个人就是査蒂•史密斯本人。她是自己最猛烈的批评家。她指出：“我怀着写一本巨著的巨大野心，但是我不认为它就是那本巨著。”

此外，媒体对《白牙》的过分反应也让她觉得难以承受。她说：“我希望可以继续乘地铁，我希望拥有正常的生活。我不喜欢被人盯着看的感觉。”

2002年，为了获得精神上的清净，盛名之下的她选择离开英国来到美国哈佛大学攻读硕士学位，继续从事写作。

主要作品有：《白牙》（White Teeth）、《搜集签名的人》（The Autograph Man）和《论美》（On Beauty），三部作品三次入围布克奖，并各自斩获诸多文学奖项。

“小说是一条双向道，两边的人都需要付出努力。正确的阅读，和写作一样，都是非常有难度的事情。” ——査蒂·史密斯
