Why do our teeth stain?

First of all, if your teeth aren’t perfectly white, it’s normal! Some people may naturally have 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 finding a place to buy them may feel pretty impossible!

Due to the high levels of hydrogen peroxide found in these whitestrips and the associated risks to oral health Crest whitestrips are banned in the UK.

These strips 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 Whitening strips work?

Crest 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 don’t fret. The Environmental Working Group rates it as a safe adhesive that doesn’t bioaccumulate or disrupt hormones. 

Crest teeth whitening strips are fortified with carbomer, contributing to the gel’s longevity. Though safe in controlled quantities, prolonged exposure may lead to gum irritation. The primary whitening agent, hydrogen peroxide, efficiently eradicates surface stains and diminishes dentin discolouration.

Unfortunately, the same hydrogen peroxide can compromise oral health by disrupting the balance of beneficial bacteria within the oral microbiome, which plays a crucial role in maintaining overall oral health.

Crest whitening strips ingredients

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 their products contain the following:

• Water: To prevent teeth dehydration
• Glycerin: To thicken the gel and helps it adhere to your teeth
• Hydrogen peroxide: To whiten the teeth
• Carbomer: To make the gel adhesive
• Polyvinylpyrrolidone: Which makes the gel adhesive
• PEG: To thicken the gel and make it stick
• Acrylates copolymer: Thickens gel and keeps strip in place
• Sodium hydroxide: Which makes the pH neutral
• Sodium saccharin: To make the strips taste better
• Pyrophosphate: To protect 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.

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, because 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.

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

Crest Whitening Strips contain ingredients such as hydrogen peroxide, sodium hydroxide, and PVP, which have the potential to cause damage if misused. In the UK, these strips are not widely available due to the high concentration of hydrogen peroxide. So, it is important to use these products as directed to minimise the potential for harm.

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.

Uneven whitening

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 Whitening strips in the UK

It hasn’t always been easy to source Crest whitening products in the UK, in particular their teeth whitening strips, but don’t worry there are lots of other teeth whitening strips on the market. Let’s get started with some alternative whitening strips.

Snow’s Magic Strips

Snow is well known for its popular whitening kit, but have you heard about their whitening strips? Snow’s whitening strips are officially called The Magic Strips, and they definitely live up to their name. According to Snow, 90% of customers get a whiter smile after just one use.

These whitening strips use Snow’s new P3 Technology and take only 15 minutes per treatment, unlike other brands that take 30 minutes. They also come in two flavours, lavender and mint, so they taste pretty good too.

The Magic Strips contain hydrogen peroxide, and they dissolve right onto your teeth. Other brands are usually the peel-off type, which leaves a gooey mess on your teeth. The full ingredients include the following:

Pectin, PVP, glycerin, hydrogen peroxide, water, peppermint aroma, pentasodium triphosphate, sodium hexametaphosphate, polysorbate 80, natural lavender aroma, sucralose, limonene, and linalool.

There are 28 treatments in a box of Snow Magic Strips (14 for top teeth and 14 for bottom teeth), and they cost $49, or roughly £35 which equals $1.75. or just £1.27 per treatment.

Hismile’s PAP+ Whitening Strips 

Hismile’s PAP+ Whitening Strips are peroxide free and instead contain Phthalimidoperoxycaproic acid (PAP) as the active ingredient. Hismile’s PAP+ formula is specifically formulated to not only safely whiten your teeth, but address pre-existing sensitivity and remineralise your enamel.

The PAP+ formula whitens teeth without causing irritation or sensitivity to your gums and teeth like other types of whitening strips. It also contains potassium citrate to help desensitise teeth and nano-hydroxyapatite to remineralise them.

To use these strips, make sure your teeth are dry, to begin with, and then apply the long strip to your top teeth and the shorter strip to your bottom teeth. Leave the strips on your teeth for 30 minutes while you do other tasks, or sit and relax while you wait. Then remove the strips, rinse your mouth with water and make sure you don’t swallow any of the residues in the process. 

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 aftertaste 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:

Product Summary

Let’s take a closer look at these alternatives, and compare and contrast them 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
• 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. 

Snow professional teeth whitening systems are produced in the USA and use hydrogen and carbamide peroxide in a formula designed to be suitable for sensitive teeth.

Rather than applying the gel using mouth trays, Snow’s revolutionary system lets you paint the serum directly onto your teeth. This means it uses a lot less gel and there is no risk of it squirting out and damaging your gums.

Included in the basic Snow home whitening kit is:

Snow’s Teeth Whitening Kit

• A mouthpiece with built-in LED lights
• 3 whitening wands (1 wand = 21 treatments)
• 1 extra-strength whitening wand
• Teeth whitening progress tracker

Check out our full write-up of Snow for more details, or read about the wireless kit.

Conclusion

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 not as easily sourced in the UK as they are in the US. This is because of the quantity of hydrogen peroxide in the ingredients creating a greater risk of enamel and dentin damage, increased tooth sensitivity or even pain when using the teeth whitening strips. However, these side effects are not exclusive to the crest whitestrips and a potential side effects of most whitening products.

However, this being said, 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.
