Buying guide for最好的牙齿美白条
Ask ten different people what makes a person beautiful, and you’ll probably receive ten different answers. But if there’s one aesthetically pleasing feature nearly everyone can agree upon, it’s pearly white teeth. Case in point: the teeth whitening industry is estimated to make more than $10 billion annually.
Fortunately, you needn’t pay anywhere near that amount to treat your teeth at home. In fact, you could spend around $1 or $2 per day for results. Teeth whitening strips safely remove certain stains from the teeth, leading to a much-improved smile.
If you’re ready to start whitening at home, please see our product list above, where we’ve outlined the best teeth whitening strips available. If you’d like to learn more about teeth whitening strips, please continue reading this shopping guide.
牙齿美白条如何工作
Teeth whitening strips are typically made of a thin plastic called polyethylene. This plastic makes the strip flexible enough to fit the teeth yet tough enough to avoid tearing.
The chemicals found on whitening strips break down stains on the teeth. The strips also contain an adhesive that ensures continuous contact between the chemical and the teeth during therapy.
The chemicals
现代牙齿美白条应包含两种化学物质之一：过氧化氨基甲酸酯或过氧化氢。基于过氧化物的化学物质消除了表面污渍和嵌入式表面污渍。同时，这些化学物质不被认为会损害搪瓷。
Older teeth whitening strips may have used other chemicals that aren’t as safe as carbamide peroxide and hydrogen peroxide.
The adhesive
不同的带状品牌使用不同类型的粘合剂。粘合剂的质量可能会影响美白过程的成功。值得注意的是，并非所有的美白条具有相同水平的牙齿。
当评估牙齿whitening strips, we look at the cost per strip as well as the number of strips per package to ascertain value.
一些美白条可以快速易于应用，而另一些则可能有些棘手。在评估牙齿美白条时，我们考虑申请过程的简单程度。
在我们的研究过程中，我们考虑了美白条是否具有任何明显的特征或成分，例如敏感牙齿或天然成分的温和配方。

安全of whitening strips
如上所述，牙齿美白条通过将化学物质放在牙齿上来工作。每种产品都包含其自己的一套应用和使用指示。确保精确地遵循这些指示。以下是一些需要理解的其他安全问题：
Concentration of chemicals
美国牙科协会（ADA）建议在美白条中的化学物质浓度有限。具体而言，条带应含有10％或更少的过氧化氢或35％或更少的碳胺过氧化氢。产品框或文献应提供有关化学物质浓度的信息。必威体育娱乐app
牙龈和组织
The chemicals used on teeth whitening strips can be dangerous if used improperly.
For example, they shouldn’t touch areas of the mouth other than the teeth.
Avoid touching your gums with whitening strips for extended periods.
Tooth sensitivity
如果您的牙齿通常对寒冷或热量敏感，它们也可能会对美白剥离化学物质做出反应。
Teeth have different layers that protect the dentin layer and the root. Enamel and cementum are the primary protective layers. If these layers are damaged through cavities, micro-fractures, or gum disease, the dentin layer is exposed, causing pain.
对于这些产品而言，对化学物质敏感性的敏感性是一个常见的问题。
Overuse
Don’t exceed the prescribed amount of wear time for these strips. You can find the recommended amount of wear time in the packaging.
Excessive whitening strip use could damage the tissues of your mouth. Do not use whitening strips more than once per day, and do not wear them for too long. You could permanently damage the enamel on your teeth through overuse.
可以理解的是，有些人对根据盒子上的说明不满意自己的能力。如果这描述了您，您可能需要花费多余的钱才能在牙医办公室执行该过程。
为了你的安全
You may be tempted to skirt the directions to achieve faster results, but the threat of tooth damage is real, and it’s not worth it.

美白条实际上有效吗？
对美白条是否有效的问题的简短答案是肯定的。但是，消费者应考虑以下因素：
染色的原因
出于不同的原因而发生牙齿染色。例如，喝茶，咖啡和红酒可能导致牙齿染色。使用烟草也会引起重大染色。有时，随着年龄的增长，牙齿会弄脏。
Whitening strips should provide at least some benefits for people with these types of stains, but they’re not necessarily a cure-all.
"Whitening strips with carbamide peroxide break down into hydrogen peroxide and urea. So in reality, all teeth whitening strips today make use of hydrogen peroxide in some form."

在所有情况下，条不起作用
尽管美白条适合大多数人，但它们并不适合所有人。这取决于牙齿的变色类型。
For example, if you have suffered a significant injury that damaged the dentin layer of a tooth, it may turn gray. This type of stain isn’t fixable with a whitening strip.
Additionally, some medications can cause permanent staining that strips cannot alleviate.
专家提示
牙齿美白条是否适合您，在很大程度上取决于您的变色背后的原因。某些变色问题无法通过条带纠正。

比较费用
When comparing the cost of one type or brand of whitening strip to another, don’t just look at the price on the box. Instead, we urge potential buyers to “do the math” to determine the cost per strip.
When you read the box, look for the following key information to determine your overall cost:
不同产品每盒或包装都带有不同数量的条带。盒子应显示其包含的条带的总数。请记住，如果盒子包含20条条，则意味着上牙有10条带有10条条带，下牙有10条。
有时，产品包装会列出其包含的日子数量。因此，如果盒子有足够的条带供10天使用，则意味着它具有20个总条。
Once you’ve determined the number of strips included, divide the price of the box by the number of strips so you can compare the cost of different brands. For example, if a box with 20 strips costs $25, the cost per strip is $1.25, and your daily cost would $2.50.
你可知道？
美白条将不适用于冠状，假牙或馅料。他们只白牙齿。

尖端
每个品牌的美白条规定了自己的应用技术。因此，即使您以前使用过其他条纹，也要仔细阅读指示以获得最佳结果。
如果您过去的牙齿有问题，例如奇怪的染色或灵敏度，请在使用这些产品之前先检查牙医。
请勿将条带入牙科工作。
请勿比规定更频繁或更长的时间使用条。过度使用可能导致牙龈或其他组织损坏。

FAQ
Q. How fast do strips work?
A.美白条可能对某些人很快起作用。一两次治疗后，您甚至可能会注意到一些美白益处。例如，我们的入围名单上的Crest 3D白色专业效应条通常很快。
但是，在一些条带和某些类型的牙齿的情况下，需要进行多种应用，然后才能看到差异。
Q. Are the whitening effects of strips permanent?
A.Because staining occurs naturally from food and drink, the whitening from strips isn’t permanent. Over time, the teeth will yellow and stain again. You’ll most likely want to repeat the whitening process at some point down the road.
Q. Why do some teeth whitening strips have different directions for use?
A.The instructions for use on any given package relate to the chemicals on the strips. Some strips use a lower chemical concentration, so they need to adhere to the teeth for longer periods to be effective. This type of low-concentration strip may also require a 20- or 30-day regimen for best results.
Strips with a higher chemical concentration may provide maximum whitening within seven days. Read the product directions carefully to understand the time period you must wear them.
问：我怎么知道是否牙齿美白条产品安全使用吗？
A.在过去十年左右的时间里，牙齿美白条发生了很多变化。早期的美白条带来了安全问题，因为一些产品用二氧化氯损害了牙齿的牙釉质。但是，大多数现代产品都比二氧化氯使用更安全的化学品混合物。（给买家注意：不要购买使用这种化学品的美白产品！）
And don’t panic if your whitening strips don’t carry the American Dental Association (ADA) seal of approval. As a matter of fact, no whitening strip products are on the ADA’s list at the time of this writing.
FDA也不调节牙齿美白条产品。
Q. What is the biggest problem with using whitening strips?
A.One common problem people experience with these strips is pain from a sensitivity to the chemicals. A messy application or removal process is another common complaint. Some strips don’t stick well to the teeth, making it difficult to talk while using them. Others stick so well that they’re difficult to remove without making a huge mess. Some strips must be scraped off the teeth.
阅读客户评论是洞悉特定品牌在牙齿上百度必威下载保持或脱离牙齿的最佳方法之一。
Q. How do at-home whitening strips differ from those at the dentist’s office?
A.牙医办公室的条和凝胶通常比在居住的条上具有更高的化学物质浓度。这使牙医办公室的美白产品可以更快地工作。牙医使用这些高度浓缩的化学物质，因为它们能够保护您的组织免受化学物质的侵害。
如果您要在家中使用更高浓度的化学物质，则可能会损坏牙龈。在不触摸牙龈的情况下，将牙齿上的条完全对齐是太难了。这种乏味的行为最好留给专业人士。
