Why do our teeth stain?
First of all, if your teeth aren't perfectly white it's normal! Some people may have naturally pearly whites, but it’s perfectly healthy for the rest of us to have teeth tinged with yellow or grey.
Tooth enamel is a thin blueish-white layer and it's translucent, so some of the colour from the dentin beneath shows through. Since dentin is dark yellow, it can give teeth an off-white or yellow appearance. So, your teeth may naturally be more yellow than white.
However, your tooth colour could also be caused by staining. Staining can generally be divided into three main categories:
- Extrinsic: staining caused by food, drink or tobacco that only affects the tooth's enamel
- Intrinsic: discolouration inside of the tooth, not just on the surface
- Age-related: enamel gradually wears away with age, exposing more of the yellow dentin underneath
So, now that we have discussed what causes the stains on our teeth, let's get stuck into how to whiten them!
What are Crest Whitestrips?
Crest 3D White strips are the most searched for brand of teeth whitening strips in the UK, even though they are not easy to buy here!
These strips are very similar to other teeth whitening strips. They are thin, usually transparent and made from a plastic called polyethylene. Each strip is coated on one side with a gel that contains a whitening agent, usually hydrogen peroxide.
There are generally two strips included that are safe for one-time use: one for the top teeth, and one for the bottom teeth. These strips are flexible and conform to the shape of your teeth, keeping the whitening gel in place.
How do Crest Whitestrips work?
Whitestrips use polyvinylpyrrolidone to make the strips stick to your teeth and stay in place. Polyvinylpyrrolidone is quite a mouthful and may sound suspicious, but the Environmental Working Group rates it as a safe adhesive that doesn't bioaccumulate or disrupt hormones.
Crest teeth whitening strips also contain carbomer to add more staying power to the gel. This ingredient is safe in the small quantities used in the strips, however, adhesives like this can cause irritation to gums in the case of overexposure.
The whitening ingredient in this brand, and indeed in many whitening solutions, is hydrogen peroxide. Hydrogen peroxide is effective in eliminating surface stains, and it can also lessen the yellow appearance of the dentin.
Unfortunately, hydrogen peroxide can also have a negative effect on your health. Your oral microbiome comprises bacteria, some of it very beneficial to your oral and overall health, and hydrogen peroxide kills the beneficial bacteria.
What are the ingredients in Crest whitening strips?
We've gone over a couple of the Crest whitening strips ingredients, so let's have a look at the rest. According to the Crest website:
- Water: Prevents teeth dehydration
- Glycerin: Thickens gel and helps it adhere to teeth
- Hydrogen peroxide: Whitens
- Carbomer: Makes gel adhesive
- Polyvinylpyrrolidone: Makes gel adhesive
- PEG: Thickens gel and makes it stick
- Acrylates copolymer: Thickens gel and keeps strip in place
- Sodium hydroxide: Makes pH neutral
- Sodium saccharin: Makes the strips taste better
- Pyrophosphate: Protects against tartar (only in Crest 3D White Whitestrips Stain Shield)
How to use Crest whitening strips
Top tip: Don’t brush your teeth before applying the strips, this will enable the whitening strips to stick to your teeth better.
- Apply the strips: To apply, peel off the liner from the back of the whitening strip, and then place the gel side of the strip along the front of your teeth, lining it up with your gum line. Press the strip against your teeth and fold the extra width of the strip behind your teeth. Follow this procedure for both upper and lower arches.
- Usage frequency: Make sure to read the instructions on the product that you are using. Some should only be worn once a day, while others require two uses per day.
- Application time: Always follow the instructions on your specific white strips. The recommended time frame can range from 5 minutes to 45 minutes. The time usually depends on the concentration of the whitening formula. Wearing them for more time than directed won't result in whiter teeth, and may cause damage.
- Treatment time: Wear your strips for the directed treatment time. Make sure to check the instructions as some treatments last just a week, while others can last for a month.

Where can you buy Crest whitening strips in the UK?

- 3D Whitestrips Glamorous White
- Whitestrips Arctic Mint
- Whitestrips Charcoal Mint
- Crest Whitening Strips Supreme Flexfit
Can you buy Crest whitening strips on Amazon in the UK?
No, sites such as Amazon don't sell Crest whitening strips in the UK due to the fact that the quantity of hydrogen peroxide in the ingredients is too high for the UK regulations. It's worth double-checking the ingredients of Crest whitening strips sold in the UK against the ingredients in those sold in the US, as it may change the level of efficacy.
Crest whitening strips UK review
Jen Garside reviews Crest 3D Professional Effects
“The strips promise visible effects in just three days, and I wasn’t disappointed. After five strips, I was extremely pleased with the effects.”
In this Glamour article, Jen's aim was to review teeth whitening products with hydrogen peroxide as the main ingredient. She reviews Crest 3D Professional Effects Whitestrips first and found she was incredibly pleased with the results. Jen explains that she has always struggled with keeping her teeth the right shade of ivory, and has even gone as far as to apply more fake tan to her skin to make her teeth appear whiter!
In her review, Jen starts with applying the strips. She says they are easy enough to apply, you just need to be careful to avoid your gums so that you don't cause unnecessary irritation. Telling the strips apart is also a simple matter of the longer one being for the upper teeth and the shorted strip for the lower teeth.
Jen was very happy with the effects, saying that after just 5 days she could see a difference already.
Jen's review of Crest 3D Professional Effects
Jen also reviews Crest 3D Whitestrips 1 Hour Express Treatment and found that they were great for use before a big event, such as a wedding. But, due to the fact they were uncomfortable and left her with a dry mouth, she would save the rest of the box, and only use them for very special occasions.
Crest whitening strips USA review
SimplyPop's Crest Whitestrips Luxe reviews
Shawn has a beautiful smile, but his teeth are a touch yellow which is the issue he wants to address. He takes us through a three-month journey of his experience:
Shawn opted for the Crest Whitestrips Luxe, which also came with a whitening express treatment as well. He says he really likes them because they work really well, but, cautions his viewers to be careful with coffee, wine and general oral hygiene. This is because, as Shawn reminds us in his review, teeth whitening is not just a quick fix, you have to be dedicated to taking care of your smile.
You can watch the rest of his review in the video below:
Do Crest whitening strips cause any problems?
There's always at least some risk of causing harm to your teeth or gums with any whitening treatment, and Crest White Strips are no exception.
Damage to gums
In the UK, Crest whitening strips are a banned product due to the amount of hydrogen peroxide in the ingredients. However, in the USA, the ADA has given their Seal of Acceptance to some of the Crest teeth whitening products but caution that overuse of these products can cause tooth sensitivity and gum damage. Damage can be caused by hydrogen peroxide, sodium hydroxide and PVP, all of which are ingredients in these strips.
Damage to teeth
A study by Experimental Biology found that hydrogen peroxide, a key ingredient in these and other over-the-counter whitening options, can harm the dentin that resides under your tooth's enamel. The results found that one of the major proteins in dentin was breaking down with the use of strips, and that collagen actually disappeared.
Additionally, whitening products may cause damage to the tooth's enamel, which can result in tooth sensitivity and pain, as well as increase the risk of cavities.
Crest 3D whitening strips can only do so much when it comes to whitening your teeth, they are only able to whiten the surfaces that they completely cover and adhere to. It can be difficult to ensure full coverage with flat strips, especially as in the hard to reach areas between your teeth.
It can also be hard to fully cover the contours where your teeth meet your gums without causing damage to your gums. The result is sometimes a white centre with yellow or grey edges.
Disrupting your oral microbiome
Hydrogen peroxide, the main whitening agent in these strips, also kills bacteria. That might sound like a good thing, but there is a lot of bacteria in our mouths that we need to stay healthy. Without a proper balance of these beneficial bacteria, you have a higher chance of infections and cavities, as well as bad breath and other general health problems.
Best alternatives to Crest Whitestrips in the UK
Although it's possible to source Crest whitening products in the UK, we can’t be sure if they would be a genuine product or a fake. Which could mean they might be ineffective or even contain harmful ingredients. And we can’t be sure if the ingredients would be the same or different to comply with UK law.
Not to worry though, there are plenty of alternatives that you can buy in the UK that do comply with UK health regulations.
Here are some alternative products that you can check out:
Spotlight Oral Care Whitening Strips
Spotlight has an extensive range of dental products but is best known in the UK for its whitening products. The whitening strips are an alternative to Crest Whitestrips that also uses hydrogen peroxide. However, these strips comply with UK health regulations and have less than 0.1% hydrogen peroxide, so can be legally sold over-the-counter.
Spotlight Oral Care Whitening Strips come with a complimentary tube of Spotlight Toothpaste for Whitening. Together, these products are known as the Spotlight Oral Care whitening system. There are 14 days worth of treatment in each pack, to be used in conjunction with the toothpaste.
The downside of these strips is that they are a little more expensive than other brands, costing £39.95. And, each set of strips must be worn for an hour, which is longer than other whitening strips.
Fairywill Gentle Whitening Strips
Fairywill Gentle Whitening Strips, are just that, gentle. They don't use hydrogen peroxide as an ingredient yet are still tough on stains with their effective teeth whitening ingredient. They claim their gentle strips won't irritate your gums and are low sensitivity.
Fairywill whitening strips use new v-shape technology which they say fit your teeth better making them more comfortable to wear on the go, and more easily removed afterwards. They are very cost-effective, as you get 44 strips (22 treatments) in each pack which works out at about 70p per treatment.
These whitening strips remove all types of stains, including coffee, wine, tea and carbonated drinks.
Mr Blanc Teeth
Mr Blanc Minty Fresh Teeth Whitening Strips confidently claim their non-peroxide product is safe and effective. Let's have a look at what they say.
The first point they make is that the strips will noticeably whiten teeth without causing any teeth sensitivity. They state that their product will achieve a “clinically proven average of 3 shades whiter in 14 days”.
Minty freshness and no weird after taste is another positive feature. However, the taste does not seem to be a point that is mentioned very often in the Amazon reviews. People seem to mention the quality, rather than the taste, more often than not.

Pro Teeth Whitening Co Charcoal Whitening Strips
These activated charcoal teeth whitening strips have quite a unique feature in that, they are black in colour. Don't let that put you off, activated charcoal is used in quite a number of teeth whitening products.
Pro Teeth Whitening Co Charcoal whitening strips were formulated by dentists, and are made from 100% naturally derived ingredients including coconut oil and cellulose gum. They are made and packaged in the UK and Pro Teeth Whitening Co guarantees quality in every batch. They have no added hydrogen peroxide or fluoride and claim to not cause gum irritation or damage to teeth enamel.
In each box, you get 28 strips (14 day supply) that will remove tough stains from the usual culprits, including coffee, tea, wine etc.
They are easy to apply, and nicely fit the contours of the teeth. But, make sure you brush your teeth afterwards to make sure you don't leave any black gel on your teeth!
So, now that we have had a brief chat about the Crest whitening strips alternatives, let's take a closer look and compare and contrast them to in the table below:

Best alternatives to teeth whitening strips
Teeth whitening strips are not the only method for whitening teeth. There is a wide variety of alternatives at different price points, to choose from, some options include:
- Laser teeth whitening at the dentist
- LED whitening (e.g. Philips Zoom)
- Professional bleaching kits
- At-home whitening kits
- Treatments combining in-office and at-home whitening (e.g. Enlighten)
If you want the best result possible when it comes to whitening your teeth, we recommend that you get your teeth whitened in practice by a dentist.
If you are looking for a less expensive option, that still provides good results then we recommend an at-home whitening kit.
Let’s look at some of our favourites:
Smile Avenue whitening kit
The Smile Avenue whitening kit is a safe and effective alternative to Crest whitening strips in the UK. It can be sold and bought in the UK because the active ingredient is Phthalimidoperoxycaproic Acid (PAP) rather than hydrogen peroxide. PAP is not banned for use in products in the UK, and it's proven to be effective at whitening teeth.
Smile Avenue claims to be great for sensitive teeth, as it is more gentle than other teeth whitening kits. One of its main ingredients, Hydroxyapatite, works to remineralise your enamel. This is a great feature as other whitening treatments can make teeth feel more sensitive, and even damage the teeth.
The LED technology utilised in this home whitening kit helps to speed up the treatment timescale. The kit comes with four pens of gel that will last 24-30 days of treatment. When you need to buy more pens, the refills are at affordable prices.
If you're not happy with your purchase, Smile Avenue will give you a full refund with their 30-day money-back guarantee. And, they offer free shipping, and if you use discount code DENTA10 you get 10% off your entire purchase!
If you want to know more about this product you can read our full review of Smile Avenue.
Snow whitening kit
Snow is an innovative system that uses a professional-strength whitening gel and an LED mouthpiece to speed up results. There are two main product options with Snow, their Original kit, and their Wireless kit. Both kits come with an LED mouthpiece and whitening wands with advanced whitening serum. It also includes a wireless kit which means you can use it in the shower or on the go!
There are myriad reasons that make Snow our recommended at-home whitening kit, but here are just a few:
- Fast whitening: You only have to use your Snow kit for 9 minutes per day to see results. And full results come after the 21-day treatment period.
- Lasting results: The whitening offered by Snow lasts for over a year.
- Easy on gums: With Snow, you paint the whitening gel directly onto your teeth. With other brands, you put the gel into trays or fit strips along your gum line as best as possible. Both of these methods can result in excess gel getting onto your gums and causing damage. With Snow, the gel stays where you apply it.
- Refills: When you want to refresh your results, you don't need to purchase a whole new kit. Instead, you can order refills. This is both eco and wallet-friendly.
- Affordability: Snow is one of the only at-home systems that offers professional-level results at a fraction of the cost.
As you can see from these Crest 3D white strips reviews, Whitestrips are an effective method to whiten stained teeth. They provide a relatively simple way to whiten your teeth from home, and for a fraction of the price of professional, in-office whitening.
Crest White strips are hard to come by and are actually banned in the UK. Not only this, they cause a risk of enamel and dentin damage and increased tooth sensitivity or even pain when using this or any other kind of whitening product. However, the American Dental Association has given Luxe Whitestrips their Seal of Acceptance, so you can feel confident knowing that the professional community stands behind this product.
If you are concerned that the product is banned in the UK and would like to use something that is potentially safer, and easy to buy then we recommend trying an at home whitening kit like Smile Avenue, or Snow.
White strips alone won't be able to provide the same level of whitening that you would get at the dentist's office, which is why we recommend Smile Avenue's whitening kit. Smile Avenue is an at-home kit that uses a professional-strength whitening gel and an innovative LED mouthpiece to drastically whiten teeth with results that last for more than a year. You can read more about Smile Avenue to find out if it's a good option for you.
Can you buy Crest Whitestrips in the UK?
It is illegal to sell Crest Whitestrips in the UK due to the quantity of hydrogen peroxide in the ingredient. However, you can still find them for sale if you search online. It is possible to find most of Crest's whitening strips products on eBay and a few other websites.
Do Crest White strips work after one use?
You won't see any noticeable results after one use unless you use the Express whitening strips. These work in just an hour to remove surface stains for a noticeably whiter smile. Standard treatments will gradually produce results, and to get full results, you should stick with the entire treatment course.
How often do you use Whitestrips?
Whitestrips are meant to be used once per day, every day. You can potentially use an Express whitening strip to supplement this, but, make sure to follow the manufacturer's instructions. If you skip days, you may not see the same results as you would if you were consistent with the whitening treatment.
