去除牙齿污渍的好方法

去除牙齿污渍的好方法

Given the rise in popularity of vlogging and social media platforms, where a picture or video is worth a thousand words — and perhaps a thousand new followers — people are more conscious about their appearance than ever before. This, of course, includes the appearance of their teeth.

随着视频博客和社交媒体平台的流行，一张照片或一个视频胜过千言万语，或许还有一千个新粉丝，人们比以往任何时候都更加注重自己的外表。当然，这也包括你的牙齿看起来好不好。

The pursuit of whiter teeth has also been on the rise due to the increase in online meetings on platforms, like Zoom. Teeth improvement has now become such a focus that it has been described as "the new boob job" (via The Guardian). It has even become enough of a phenomenon that it has sprouted a niche of "dental influencers" (via Get The Gloss).

由于Zoom等平台上在线会议的增多，人们对美白牙齿的追求也在上升。牙齿改善现在已经成为人们关注的焦点，以至于被称为“新隆胸手术”(《卫报》)。它甚至已经成为一种现象，并且出现了一个“牙科影响者”的利基市场。

"Zoom has been amazing for our industry," Dr. Uchenna Okoye, owner of a dental practice and dental influencer, told The Guardian. "People are staring at themselves and they see angles, like the side view of their face, what other people see of them."

“Zoom对我们的行业影响是不可思议的，”牙科诊所和牙科专家乌钦纳·奥科耶博士告诉《卫报》。“人们开始从各个角度盯着自己看，就像别人看到的他们的侧脸。”

Anna Middleton, the founder of London Hygienist, told BDJ Team that the best way to remove stains from teeth varies from person to person. She adds that teeth naturally vary in color and shading due to the thickness of tooth enamel, so it's important to identify what is causing the discoloration before taking any whitening action.

London Hygienist 的创始人安娜·米德尔顿告诉BDJ团队，去除牙齿上污渍的最佳方法因人而异。她补充说，牙釉质的厚度决定了牙齿的颜色和阴影的自然变化，所以在采取任何美白行动之前，确定是什么导致了牙齿变色很重要。

Middleton also points out that there is a difference between stain removal and whitening. Stain removal is what is typically achieved at the dentist when you get your semi-annual cleaning. The hygienist uses special dental instruments to remove plaque deposits, followed by polishing. Whitening, on the other hand, is a process that involves hydrogen peroxide and carbamide peroxide, which break the carbon bonds of the yellow stains on your teeth.

米德尔顿还指出，去除污渍和美白之间是有区别的。当您每半年进行一次清洁时，牙医通常会去除污渍。卫生员使用特殊的牙科器械去除牙菌斑沉积物，然后进行抛光。另一方面，美白是一个涉及过氧化氢和过氧化脲的过程，它们会破坏牙齿上黄色污渍的碳键。

However, Middleton states that the only way to really whiten teeth safely and effectively is by getting professional treatment. Whitening toothpaste can have some whitening effects, but it can be abrasive and damage enamel. The experts at the Mayo Clinic align with this view, noting that whitening toothpaste can't change the natural color of your teeth. It also can't lighten a stain that goes deeper than a tooth's surface.

然而，米德尔顿表示，真正安全有效地美白牙齿的唯一方法是接受专业治疗。美白牙膏可以有一定的美白效果，但它会磨蚀和损伤牙釉质。梅奥诊所的专家同意这一观点，他们指出美白牙膏并不能改变牙齿的自然颜色。它也不能减轻比牙齿表面更深的污渍。

To maintain a bright smile, Middleton recommends brushing with an electric toothbrush, rinsing after you drink dark foods and liquids, chewing gum to increase saliva flow, avoiding smoking, and dialing back on red wine and coffee — and, of course, go for a cleaning at least once a year.

为了保持灿烂的笑容，米德尔顿建议用电动牙刷刷牙，在喝了深色食物和液体饮料后漱口，嚼口香糖以促进唾液流动，避免吸烟，少喝红酒和咖啡——当然，每年至少要清洁一次。
