Do Crest White Strips Really Work? Pros, Cons and Results

Crest White Strips are the world’s number 1 rated teeth whitening brand and can whiten your teeth considerably. But do they really work?

We’ll take a look at Crest White Strips and see if the science matches up.

What are Crest Whitening Strips?

Crest White Strips are pairs of strips coated on one side with a peroxide-based whitening gel. They are placed on your teeth for 30 minutes a day, and they gradually whiten your teeth.

How do teeth whitening strips work?

Teeth whitening strips brighten and whiten your smile by bleaching stains with carbamide peroxide or hydrogen peroxide. The former is a molecule that becomes hydrogen peroxide when it’s touched by water.

These peroxides penetrate your tooth’s outer layer (known as enamel) and move into the deeper dentin layer. Once there, they bleach chromogens, the pigmented molecules inside and outside the tooth that cause staining.

Do Crest White Strips really work?

In short, yes! They are seriously good, to be fair, but it depends on how you use them and the severity of your stains.

Most people will see a decent difference in their teeth within a few days of using Crest Strips. Full results take 20 days, which is one full retail box (20 pouches). If you do the full course, the results are really impressive.

Are teeth whitening strips effective?

Generally speaking, teeth whitening strips are effective, but you need to buy high-quality strips with the best ingredients to get the full effect. While they usually contain the peroxides mentioned above, some may contain chlorine, which is promoted as a safer alternative but is actually controversial and may make your teeth more prone to re-staining and sensitivity.

We recommend using trusted teeth whitening products, like Crest 3D White Strips Glamorous White and Crest 3D White Whitestrips – LUXE Edition.

Pros and cons of teeth whitening strips

While teeth whitening strips are definitely effective, there are advantages and disadvantages to using them. Understanding both sides of the coin will help you make the right decision for you and your (soon-to-be) pearly whites.

The pros

✓Affordability

Compared to whitening services and products offered by dentists, teeth whitening strips are certainly cheaper. Whether you don’t have the funds for in-practice treatments or simply aren’t prepared to spend hundreds (if not thousands) on a brighter smile, strips give you the confidence boost of whiter teeth without breaking the bank.

✓Readily available

You can buy whitening strips almost anywhere, including online from us at Advanced Whitening. We provide the highest-quality whitening strips on the market, so you can achieve the smile you deserve.

✓Easy to use

Whitening strips are exceptionally easy to use. Simply peel off the cover and press the strips firmly onto your upper and lower teeth. Leave them for 30 minutes (or the time stated on the packaging), then remove them.

The cons

✕Risk of weakened or damaged enamel

If you overuse whitening strips (i.e. don’t follow the instructions), they can damage or weaken your enamel through excessive bleaching. When this happens, your teeth may look grey, blue, or even translucent.

✕Tooth or gum sensitivity

Some people who use whitening products like strips notice mild tooth sensitivity afterwards. Others experience gum irritation or erosion of fillings. Luckily, you can minimise this risk by following the packaging instructions and using only high-quality strips.

✕Uneven results

Do you have cramped or crooked teeth? If so, you may not get even results from whitening strips, as they won’t fit perfectly over every tooth. You could end up with white blotches on your enamel rather than an even brightness. To counteract this, take your time when applying them to cover the entire surface of every tooth.

Tips for the best results with whitening strips

Whitening strips are easy to use, affordable, and effective, but to get the best possible results, follow our tips and tricks below:

✓Start with clean, dry teeth

Don’t brush immediately before applying whitening strips. If you brush, wait about 30 minutes, then make sure your teeth are dry.

✓Be precise with application

To avoid uneven whitening, be precise when applying the strips, because they only whiten the areas they cover. Take your time and give every tooth the attention it deserves.

✕Don’t overuse

Teeth whitening strips are safe to use in moderation, but never exceed the recommended frequency and duration. If you overuse them, you risk permanent damage and erosion of your protective enamel, which can ultimately lead to tooth loss.

✕Avoid your gums

While the peroxides in whitening strips aren’t as strong as the bleaching agents in dentist-supervised treatments, they can still damage the soft tissue of your gums. So make sure the strips don’t touch your gums. You may need to cut the strips so they match your teeth exactly.

✕Avoid dark food and drink

Avoid tea, coffee, berries, sweets, and other dark-coloured foods and drinks for a few hours after whitening to avoid re-staining your teeth.

Where to buy Crest White Strips

Crest White Strips are available online in the UK and Ireland, but you’ll need to do your research and buy them from reputable sites like Advanced Whitening.

Additional tips for teeth whitening strips

In addition to using the strips, here are some other tips:

✓Brush and floss regularly

✕Avoid smoking and excessive alcohol

Especially the smoking.

✕Limit coffee, tea and red wine

I know that’s hard!

✓Use a whitening toothpaste

Colgate, Oral-B, etc.

✓Visit your dentist and hygienist

For regular cleanings.
