Burst vs Crest White Strips: What’s Better for Whitening?

It’s a fact that our teeth get darker as we get older. Even for the oral hygiene all-stars out there, the longer we live, the more our teeth are exposed to things that will stain them. Genetics do play a part in natural yellowing or greying, along with what we eat (hello, coffee!).  But while whitening used to be limited to a service you would receive in the dentist’s chair with complicated molded trays and gels, it is now easier than ever to whiten your teeth quickly, comfortably and affordably from home and on the go.

 

The home-whitening wave began with strips, but now anything from LED light devices to whitening gels to charcoal powder have become popular ways to brighten your smile. Just like any new health trend, it can be hard to understand:

 

  1. Which products are effective at whitening your teeth?
  2. Which whitening products are safe to use?

 

Because when we whiten we are technically messing around with the enamel on our teeth, it is important to be careful about product choices. And just like many of the health products that we love and use daily, whiteners are not actually regulated by the FDA.

 

In this piece, we’ll take a closer look at whitening strips from two of the leading brands and compare them detail by detail: Crest Whitestrips, the long-standing market leader, and Burst, a new product that adds a natural health element to traditional whitening methods.

 

 

How do at-home teeth whitening kits work?

 

We all probably understand the concept of bleaching to clean something, and so using peroxide to remove stains seems like a pretty simple idea as well. But teeth are actually pretty complicated! The first layer on our teeth, or the enamel, is actually a tiny network of tubes. Staining actually happens in the next layer below, or the Dentin. Whitening works by traveling through this tubular superhighway in the enamel to reach the Dentin. In this process, the peroxide breaks up into two other compounds: oxygen and hydroxyl radicals. Now these two chemicals go to work breaking up, or oxidizing, any stains on the teeny tiny pores in Dentin, and releasing them from the tooth.

Here, the peroxide hits the outside of your teeth, or the enamel layer, and then turns into oxygen and something called hydroxyl radicals. These two compounds can then do what’s called oxidation to the stain- breaking up the substance that is causing the stain and releasing it into pieces into the mouth. For bigger and deeper stains, the more times this is done, the better.

 

 

Is peroxide safe for teeth whitening?

 

Hydrogen Peroxide is safe for home health use, just as long as it’s diluted enough. Most teeth whitening products are going to have levels of peroxide between 3% and 15%, with the lower amounts generally considered more safe. (As a point of reference, household peroxide you might keep in your medicine cabinet is usually 3%).

 

Since tooth enamel is extremely tough- the hardest substance on the body, actually- it is not easy to damage, and so it is not permanently hurt by the whitening process. What does happen is that the enamel gets dehydrated and temporarily unable to do its job of protecting the dentin. During that time your teeth are extra susceptible to new stains, and sensitive to hot and cold since the nerves aren’t protected. About two thirds of whitening kit users report having some level of sensitivity soon after using whitening products. 

 

For some people with weak or previously damaged enamel, the whitening process will make this sensitivity much worse. Those people should work with a dentist to make sure they choose a whitening product that works for them, or choose a product with a lower concentration of peroxide to use over a longer period of time. So if you have sensitive teeth, you should consult your dentist before trying DIY whitening.

 

Similarly, those who are developing an all-over gray or yellow hue to their teeth that doesn’t seem to be linked to consuming coffee, soda or wine should talk to their dentist. This is likely to be genetic (or some other condition) and might not respond to at-home whiteners like the ones in this article. Your dentist might be able to provide a service that does help, however.

 

Overall though, the research shows that most people do not have any long term sensitivity or damage from using peroxide based whitening products. The key here is to use them as directed, with time in between to let your enamel recover.

 

So now that we know how they work, let’s take a look at the differences between Burst and Crest Whitestrips whitening strips.

 

 

Burst whitening vs Crest Whitestrips: How do these teeth whiteners compare?

 

Crest has long been a household name, and so it follows that their whitening strips have held the spot for most popular home teeth whitening since day one. But a newer startup Burst has recently gained a following for its toothbrushes, floss, and whitening products that use more natural ingredients like charcoal and coconut oil. Which one should you trust? Let’s see how they compare:

 

 

Crest vs Burst Whitening

Time Commitment Peroxide Strength Additional oral health benefits ADA Seal of Approval



30 minutes 14% No Yes



10 minutes 6% Yes No

 

The main differences between the two brands are:

 

  • Peroxide strength (the concentration used)
  • Time commitment needed to see results
  • The addition of coconut oil.

 

What exactly does coconut oil have to do with teeth whitening? We dug a little deeper to see what dentists think.

How does Burst use coconut oil for teeth whitening?

 

Burst includes a special ingredient — coconut oil — in their whitening strip formula but why? Coconut oil has been used to boost dental health for literally hundreds of years. As a traditional Indian folk remedy, oils like coconut have always been used in a method called “oil pulling,” or basically using the oil as a mouth wash. This was believed to fend off tooth decay, bad breath, gum disease, dry mouth bleeding gums, dryness of throat, and cracked lips. Since a time long before toothpaste, oil pulling was even believed to strengthen teeth, gums and even the jaw.

 

But in recent times oil pulling has seen a popular comeback. Research suggests that oil pulling therapy shows a reduction in plaque, healthier gum lines, and lowered bacterial counts for people with gingivitis. The way that it is supposed to work is that oils are able to pull bacteria from all the nooks and crannies of your mouth, which then can be spit out with the oil– hence the term “pulling.” Coconut oil also has the added benefit of lauric acid which is a known antimicrobial, and a recent study found that it may also help prevent tooth decay. So by adding the coconut oil to its strips, Burst may be adding a long list of beneficial effects along with whitening.

 

 

What is the monthly cost for Crest Whitestrips and Burst?

 

Affordability goes a long way when it comes to choosing a product that you plan on using long term. When we break down the monthly cost, Burst does come out a little bit cheaper by about a dollar. It’s also sold in smaller quantities, so the $20 price tag doesn’t sting quite as badly as shelling out over twice that much for Crest Whitestrips’s six-month supply.

However, if we look into what we are getting for the money, there’s more to the story.

 

Since Crest has almost double the peroxide strength as Burst, you would in theory have to use Burst for longer to get the same results. In fact, studies do show that using a 5% peroxide product gives you the same amount of whitening as one of a higher strength if used for a longer period of time. Thus Crest Whitestrips might actually be more bang for your buck as far as how many times it has to be purchased and used, and how quickly it works.

 

Ok, now that we have a general sense of how these products work and how much they cost, let’s dive a bit deeper into what using them is like to give you a better sense which is right for you.

 

What is it like to use Crest Whitestrips White Strips at Home?

 

Source: Crest

 

Crest Whitestrips are meant to be used for 30 minutes, every day, for a period of 20 days. They work best on clean teeth without plaque, so brushing first is not a bad idea.

 

They are thin, transparent, and don’t cause excessive salivation, so they can be worn while relaxing as well as during most household activities. They aren’t super visible from a few feet away either, so it’s possible to make errands if need be too.

 

 

Whitestrips are small and are only meant to cover the front teeth. The top strip is what you would imagine: long and rectangular, covering all of the top teeth except for the molars. But the bottom strip is smaller, and its shape is a combination of two rectangles, which could take a little bit to figure out. The larger side of the bottom strip is actually meant to cover the visible front side of your bottom teeth, and the smaller one to anchor the strip in the back.

 

Once you’ve had them on for thirty minutes, it’s not a bad idea to either rinse with water or go for a full toothbrushing, based on your comfort level and how much of the sticky whitening gel from the strips remains on your teeth.

 

Crest whitestrips come in packs of 20, and the recommended use is for 20 days every 90 days. So out of three months, you can choose a time where you are able to whiten for 20 consecutive days. Ideally, you won’t be drinking coffee, dark soda or wine very much during this time period, especially just after whitening.

 

 

Whitestrips should not affect crowns, caps, or other dental work, but it’s a good idea to check in with your dentist if you have specific concerns about using whitening products.

 

 

What is it like to use Burst whitening strips at home?

 

Similar to Crest, Burst’s whitening strips are designed to be used once a day. But with Burst, you only whiten for seven days instead of twenty. And instead of waiting 30 minutes, you only need to take 10 out of your day for Burst whitening strips. So the whole whitening process takes much less time than with Crest Whitestrips.

The Burst strips themselves are very similar to Crest with one long rectangular strip for the top teeth, and a smaller double rectangle for the bottom. You simply press them on until they adhere, and go about your normal business for 10 minutes.

Just like Crest, it’s a good idea to brush first, and rinse after for best results. But with Burst, rinsing afterwards each time is more strongly advised to maximize the effects of the coconut oil. Burst says that since the coconut oil is working so hard to pull the bacteria and toxins from the corners of your mouth, it’s best to rinse and spit afterwards, just like using mouthwash. Then after your seven days of whitening with Burst, you’ll want to repeat every 90 days.

Burst comes in packs of 14 strips, meant to be replaced every 3 months. Reviewers say that they see results within a one week, and the reviews on Burst’s website average 4.9 out of 5 stars.

 

 

Do Crest Whitestrips work?

 

Users report seeing results within about 3-7 days of using Crest Whitestrips. Results will vary depending on the level of staining for each individual of course, but Crest is known for pretty quick results. Your teeth should be a shade or two lighter each time you use them.

 

But continuing to use Whitestrips for the full twenty days should both improve your results and make them last longer. For some, this initial effect can last for up to two years, and may report about 6 months. But the suggested schedule for maintaining your whitened teeth is to repeat the 20-day whitening period every 3 months.

Beyond strips: What other whitening products do Crest and Burst offer?

 

Now that we know the ins and outs of Crest and Burst’s whitening offerings, let’s take a look at the various products available from both companies. Crest now offers a blue LED light along with many of its Whitestrips kits, which they guarantee will boost the effects of using the strips as directed.

 

 

 

The LED light is worn for the last 10 minutes of wearing Whitestrips. The way it works is that the light penetrates enamel to weaken stains, accelerating the action of the peroxide in the strips. Colgate has a similar LED whitening offering ShopSmiles that we’ve previously reviewed, and we’ve also covered brands like Glowup in the past if you want to compare the top LED whiteners.

 

 

Burst may only have one line of whitening strips, but they do offer some other interesting dental products! Their claim to fame is actually a charcoal based toothbrush, but they offer charcoal floss as well.

 

 

Just like coconut oil, charcoal has a long history of being used for dental health, both to absorb toxins and whiten. And Burst is not the only company to dig into ancient history for ingredients: charcoal whitening is definitely trending.

 

 

 

What are customers saying about Crest Whitestrips and Burst?

 

Both Burst and Crest have very positive reviews. Because Crest Whitestrips have been around longer, there are generally more reviews out there. They are also sold via many websites other than their own, like Amazon, CVS, walgreens… even Ebay! So it is much easier to find positive user testimonials about Whitestrips. But that doesn’t mean no one is singing Burst praises… users seem to really like the coconut taste of their strips. They are generally considered easy and pleasant to use without much of a chemical taste.

 

 

The biggest theme we see with Burst reviews is that they do not seem to cause sensitivity or pain, and so people with sensitive teeth can safely use them. (Again, this is what the Burst reviews are saying). As far as the more natural products go, Burst strips are much easier to use than other charcoal products, and because they contain that magic ingredient, peroxide, users do see results after a few uses.

 

For Crest, people review them as easy to use with fast and dramatic results:

 

 

Crest Whitestrips are cost effective to maintain a white smile over many years, and are reliable for touch-ups before a big event or photoshoot.

 

 

The Verdict: Which at-home teeth whitener is right for you — Burst or Crest Whitestrips White Strips?

 

So which whitening strips do we ultimately recommend trying? 

 

Well, we know that Crest is a more powerful product due to its higher peroxide strength, and so it is going to work faster. So if there is an event coming up and you need a strong effect quickly, you’re going to want to reach for the Crest Whitestrips.

 

However, if you have dental health issues or are worried about enamel, or even just want to up your oral health game Burst offers more with fewer risks. The additional coconut oil and  lower peroxide content make Burst a better choice for long term use. It’s cheaper, and used for a shorter amount of time as well, making them a more convenient choice as well.

 

Like anything, the best product for you will depend on your personal needs. That includes how sensitive your teeth are, how much whitening you need and how quickly you need it done, and, as always, your budget.
