We’ve reviewed teeth whiteners for the past five years. In our most recent testing, we compared eight products for over 20 hours to see which were the most comfortable to use, offered the easiest whitening techniques and had the best customer support options. Hollywood Smiles is the best overall treatment because it offers lasting effects, doesn’t cause blisters and comes with tools to help you whiten hard-to-reach back molars. You can also find instructions and a FAQs page on the company’s website should you have any questions.

Best Overall

Hollywood Smiles

Hollywood Smiles provides comfortable and quick treatments. The gel is designed to prevent blisters and gum irritation so the treatment process will be more pleasant than some other kits.
The gel is also engineered to have a pleasant taste which, makes it easier to keep the mouthpiece in for the full treatment session. While the mouthpiece doesn’t mold to your teeth, it provides a snug fit and only needs to be used for seven consecutive days before you see results. Unlike some kits in this comparison, Hollywood Smiles provides lasting effects as long as you don’t stain your teeth with things such as coffee, cigarettes or soda. This kit comes with all of the tools you’ll need, including a whitening light to help your teeth brighten, a whitening pen so you can touch up dark spots, and a shade guide that allows you to track your progress from start to finish. Some kits do not provide these tools and can make the treatment session less effective. Some users have reported that the gel applicators broke and leaked during transit, so be sure to look out for that. Should you have any questions about how to use the whitener, you can contact customer representatives via phone or email, or you can use the instructions and the FAQs page on the company’s website. Be aware that the company can take up to 72 hours to respond to your emails.
Pros
  • This kit can make your teeth 20 percent brighter.
  • This kit creates lasting effects.
  • The gel is designed to be pleasant tasting.
Cons
  • It doesn't come with a moldable mouthpiece.
  • If you contact Viatek it can take up to 72 hours to get a response.
  • Sometimes the gel applicators leak during shipping.

Cool Teeth Whitening

Cool Teeth Whitening provides fast, long-lasting results but at a much more affordable price than many other whitening kits in our comparison.
Treatments last seven days, which is longer than some other kits but also much shorter than others. While the gel doesn’t have a pleasant flavor, it isn’t unpleasant. Perhaps most importantly, there shouldn’t be any lingering aftertaste when your treatment session is done. The gel did cause slight irritation and soreness for our testers. You mold the mouthpieces to your teeth so they have a very snug fit and shouldn’t come off easily. Unfortunately, this set doesn’t include a whitening pen so you won’t be able to touch up hard-to-reach places. However, this kit does come with a whitening light to help your teeth brighten faster, and it also comes with a shade guide so you will be able to track your teeth’s progress. Overall, this kit can help you brighten your teeth up to 20 percent. If you want to contact the company’s customer representatives, you will need to do so via email since they do not offer assistance through phone. You can also find instructions, a FAQs page and additional information on the company’s website.
Pros
  • The gel does not have an unpleasant taste.
  • Your teeth can be 20 percent brighter in seven days.
  • The mouthpiece molds to your teeth.
Cons
  • You will feel more discomfort during treatments.
  • It doesn't come with touchup tools.
  • You cannot contact customer representatives via phone.

Rembrandt

Rembrandt’s teeth whitening treatment only takes a couple hours to complete and is best if you need results fast.
Unfortunately, our testers found that these results only last for a few days, but if you only need your teeth to be whiter for a special event or activity this can help you get the temporary results you want within just one day. The mouthpieces don’t mold to your teeth and unfortunately the gel has a relatively unpleasant, lingering taste. However, the mouthpieces are designed to be comfortable and the gel shouldn’t irritate your gums or cause any blistering. Our own testers found that their teeth became 20 percent brighter using this kit, which is one of the best results we had. This kit does not come with a whitening pen for touchups, nor does it come with a shade guide so it can be difficult for you to track your teeth’s progress. Considering how long the brightening lasts, the cost is relatively high, but if you need to lighten the shade of your teeth in a hurry the price might just be worth it. If you want additional information, you can find a FAQs page and instructions on Rembrandt’s website.
Pros
  • This kit gives results in just two hours.
  • The kit is designed to be comfortable to use.
  • There is a FAQs page and instructions on the company's website.
Cons
  • The gel doesn't have a pleasant taste.
  • It doesn't come with a shade guide or whitening pen.
  • This kit doesn't provide long-lasting results.

Why Trust Us
We have tested teeth whitening kits for the past five years. In our most recent testing, we compared eight products to see which whitened most effectively, was the most comfortable to use and offered the best tools to track your progress. We paid particular attention to which gels irritated teeth and gums, and we also noted whether a gel had an unpleasant taste. We wanted the best ranking teeth whiteners to only take a small number of whitening sessions and to be comfortable. We had a tester assigned to each product so we could better understand the whitening process and how long the effects lasted for.

How We Evaluated
We had a tester for each product and had them track their progress and experiences. We noted each tester’s initial tooth shade and then when the treatment period ended we compared it against the final shade to see how well it worked. The best products brightened teeth by 20 percent while less powerful products only brightened by 10 percent. We scored products higher that provided better results. Additionally, after the treatments ended, we tracked each user’s teeth to see which whiteners lasted the longest. Products that provided long-term results scored higher in our testing.

Gels that cause minimal irritation and taste good scored higher than gels that create soreness or blisters or that taste unpleasant. Kits that come with whitening pens scored higher since they allow you to touch up dark spots. And products that come with shade guides also scored higher since they make it easier for you to track your progress.

We contacted each company to see how easy it was to communicate with them. Companies that responded to our inquiries quickly and respectfully scored higher. We also gave more points to companies that offered online assistance like instructions, FAQs pages and video tutorials.

Teeth Whiteners: What to Look For
When you are looking for the best teeth whitening options, you want a product that provides results quickly and doesn't require a large amount of effort. The best teeth whitening kits include everything you need to achieve a pearly white smile with no extra purchases. Below are the criteria we used to evaluate the best teeth whitening products.

Performance
Performance and quality are vital aspects of the best teeth whitening products. Look for testimonials and satisfaction guarantees as well as products that are clinically proven. Also, make sure the product states that it is safe on your teeth's enamel, gums and other areas of your mouth, with a snug-fitting mouthpiece or strips. The best kits keep your smile looking bright longer than just a few days after treatment.

Comfort
Drastically improving the color of your teeth won't happen in a matter of minutes. It will take time. However, many of the best home teeth whiteners make the teeth whitening process simple. They include mouth trays or strips that you wear for just a few minutes every day. The whitening gel should have a pleasant taste and shouldn’t cause any burning or blistering.

Tools

Most of the teeth whitening kits we reviewed provide all the tools you need to whiten your teeth, and some kits provide many additional items beyond gel and trays. Whitening lights can add a lot more brightness, and whitening pens can help you get hard-to-reach areas under control. Some provide a shade guide so you can accurately gauge the difference the whitening kit is making. Not all the tools are essential, so you must decide which are important to you and find a product that offers the items you want.

Help & Support
Teeth whitening makers should provide you with the information you need to use your product safely. It should also be easy to contact them without having to break down too many walls. A phone number and email address are usually enough to keep you informed, but the best manufacturers go the extra mile by interacting via social media and putting up FAQs sections with instructions.

By using the above criteria and our in-depth reviews, you can find a high-quality teeth whitening kit that gives you a Hollywood-style smile in no time.
