Keep reading to learn how it works, where to buy, and alternative tooth whitening products.

What are Crest Whitening Emulsions?

Crest Whitening Emulsions is an award-winning water-resistant gel designed to be applied to your teeth in seconds and left on all day.

Crest promises this product will leave your smile fresher and whiter. Most importantly, it causes virtually no tooth sensitivity (as verified by the Better Business Bureau).5

Its non-toxic ingredients are gentle on enamel, meaning it can be applied up to four times daily. That makes it helpful for clearing up stains after drinking wine or coffee.

And because it’s a gel and not toothpaste, there’s no need to rinse. Application takes one minute, making it perfect for those with busy schedules.

Crest Whitening Emulsions come in three varieties: 

  1. With LED Accelerator Light — Their newest addition, this comes with an 18g tube, wand, counter stand, and an LED light for faster whitening
  2. With Wand Applicator — Comes with a 25g tube, wand applicator for at-home application, and a counter stand. The wand helps reach teeth in the back of the mouth.
  3. With Built-in Applicator — Includes a 10g tube and built-in applicator for applying on the go. It’s a convenient size for when you’re out of the house or traveling.

Crest Whitening Emulsions has strong customer reviews. Allure magazine even gave it the 2021 Best in Beauty Award.3

How Do Crest Whitening Emulsions Work? 

Unlike many teeth-whitening products, we found that Crest Whitening Emulsions doesn’t cause tooth sensitivity. This is a common side effect of many tooth-whitening products using a whitening agent called hydrogen peroxide

While safe and effective, it can temporarily dehydrate teeth by leaching minerals from pores in the enamel. This exposes the sensitive layer of dentin underneath, causing sensitivity.  

Crest Whitening Emulsions uses a high amount of hydrogen peroxide (9.5%). But it does so in a different way than other brands. To learn how this works, it’s important to understand the definition of ‘emulsion.’

What’s an Emulsion?

An emulsion is a way to keep liquids from separating. Emulsions are often used to make beauty products like moisturizing creams and lotions. 

In Crest’s case, this lets their product do two things:

  1. It rehydrates your teeth by filling in the pores in the enamel, preventing sensitivity.
  2. The water-resistant base forms a protective layer for the hydrogen peroxide that keeps it from being diluted by saliva. This allows more contact time on your teeth.

The emulsion process sets Crest Whitening Emulsions apart from other whitening products. It’s a hydrating whitening treatment that allows more intense whitening for longer.

Crest Whitening Emulsions vs. Crest Whitening Strips 

Crest’s version of teeth whitening strips, the Crest Whitestrips, was introduced over twenty years ago. It’s well-regarded by both consumers and dentists alike. 

Because it’s been around so long, Crest Whitestrips has some advantages over Crest Whitening Emulsions. But in other ways, Emulsions are the superior product. 

Here’s how they differ:

ADA Seal of Acceptance

Crest Whitestrips have the Seal of Acceptance from the American Dental Association (ADA). This means it’s certified as safe and effective. 

Being relatively new, Crest Whitening Emulsions doesn’t have this currently.

Customer Reviews

Because Whitestrips have been around for so long, they have far more reviews than Emulsions.

Here’s a comparison of Amazon reviews for both products at the time of writing:

  • Crest Whitestrips — More than 73,600 reviews, nearly all positive
  • Crest Whitening Emulsions — Just over 8,000 reviews with a slightly lower rating

Sensitivity

One common complaint about Crest Whitestrips is teeth and gum sensitivity. This isn’t an issue with Emulsions. 

Treatment Time

Whitestrips take longer to see results. In contrast, Emulsions noticeably whiten teeth with just one treatment.

Flavor

Some reviews note Crest Whitening Emulsions have a more pleasant mint flavor than Crest Whitestrips.

Here’s the information presented in a table format:

Best Alternatives to Crest Whitening Emulsions

If you’re curious about other options, here are six alternatives to Crest Whitening Emulsions:

Snow At-Home Teeth-Whitening

Snow At-Home Teeth-Whitening is a bleaching tray with a built-in LED light to whiten your teeth. It comes highly reviewed and won’t cause teeth sensitivity.

Two drawbacks are price and usability. Snow’s kit currently retails for over three times the price of Crest’s own LED option. The LED also has a nine-minute application time to Crest’s three minutes. 

Auraglow Teeth-Whitening Pen

Auraglow’s Teeth-Whitening Pen is a fast and convenient way to whiten your teeth gently. Because it’s a pen, it can be used on the go, making it ideal for busy people.

It comes at a very affordable price and comes with a subscription service for added convenience.

Lumineux Oral Essentials Teeth-Whitening Kit

This complete system uses ingredients such as coconut oil and sage to whiten teeth naturally and gently. This makes it a good option for those concerned with microbiome health.

Unlike the other products mentioned, it doesn’t use hydrogen peroxide, pens, LED lights, or trays. It comes at a price comparable to Crest’s Built-In Applicator option. 

One thing to keep in mind is that two whitening strips are used daily—one for the top and one for the bottom teeth. At 14 whitening strips, that’s only seven treatments, making this a relatively pricey option.

Hismile VIO405™ Teeth Whitening Kit

The Hismile Teeth Whitening Kit is the winner in our list of the Best Teeth Whitening Products of 2024. Hismile causes zero sensitivity, even for people with extremely sensitive teeth.

However, Hismile costs about three times as much as the Emulsions + LED kit, and the application takes 10 minutes.

Crest 3D Whitestrips for Sensitive Teeth

If you love the tried-and-true Whitestrips but can’t handle the sensitivity, Crest 3D Whitestrips for Sensitive Teeth may be right for you.

They work the same as the original Whitestrips but with a new, enamel-safe whitening formula.

Colgate Optic Advanced Whitening Toothpaste

For traditional tooth-whitening toothpaste, this is a good option. This product comes with the dentist-recommended amounts of fluoride and hydrogen peroxide. 

While not as effective in whitening as the other products mentioned, it will remove surface stains. It’s also the most affordable option, making it great for those on a budget.

Summary

Crest Whitening Emulsions use a breakthrough formula to whiten teeth without causing sensitivity. The hydrating base forms a protective layer over your tooth enamel during the whitening process.

Because Whitening Emulsions are new, they lack the long-term research, customer reviews, and ADA Seal of Approval of Crest Whitestrips. However, Emulsions work faster, taste better, and are easier to use.
