What are Crest Whitening Emulsions?

Crest Whitening Emulsions is Crest’s entry into the at-home teeth-whitening market. It’s an award-winning water-resistant gel designed to be applied to your teeth in seconds and left on all day. 

Crest promises its 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 a day. That makes it helpful for clearing up stains after drinking wine or coffee.

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

Crest Whitening Emulsions comes 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 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 useful for when you’re out of the house or traveling.

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

How Do Crest Whitening Emulsions Work? 

Unlike many teeth-whitening products, Crest Whitening Emulsions doesn’t cause tooth sensitivity.

This is a common side effect of many tooth-whitening products, which use 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 actually uses a high amount of hydrogen peroxide (9.5%). But it does so in a different way than other brands.

To understand how this works, it’s important to know what an emulsion is. 

An emulsion is a way to keep liquids from separating. Emulsions are often used to make beauty care 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.

This is what makes Crest Whitening Emulsions different from other whitening products. It whitens more intensely and for a longer time while causing virtually no sensitivity.

Crest Whitening Emulsions vs. Crest Whitestrips 

Crest Whitestrips was introduced over twenty years ago. It’s well regarded by both consumers and dentists alike. 

As the name implies, it’s a series of strips you press firmly against your teeth. You wear them for thirty minutes and then remove them.

Because it’s been around so long, Crest Whitestrips has some advantages over Crest Whitening Emulsions. 

One of those is the Seal of Acceptance from the American Dental Association. That means it's certified as safe and effective. 

Being relatively new, Crest Whitening Emulsions doesn’t have this at the moment.

Crest Whitestrips also has more Amazon reviews - over 51,000 reviews, at the time of writing, and nearly all positive. 

By comparison, Crest Whitening Emulsions has just over 4,300 reviews. Crest Whitestrips also has a slightly higher overall rating.

One common complaint about Crest Whitestrips is teeth and gum sensitivity. It also takes longer to see results, whereas the emulsions noticeably whiten teeth with just one treatment. 

Some reviews also cite Crest Whitening Emulsions as having a less overpowering mint flavor than Crest Whitestrips.

What are the Best Alternatives to Crest Whitening Emulsions?

If you’re curious as to what other options there are, here are four 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 gently whiten your teeth. 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 so far, it doesn’t use hydrogen peroxide, pens, LED lights, or trays.

Here’s what’s included:

  • 14 whitening strips
  • Fluoride-free Whitening Toothpaste
  • Whitening Mouthwash
  • Bamboo toothbrush

It comes at a price comparable to Crest’s Built-In Applicator option. Reviews say it will whiten your teeth without causing sensitivity. 

One thing to keep in mind is that two whitening strips are used each day - 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.

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 so far, it will remove surface stains. It’s also the most affordable option by far, making it great for those on a budget.
