The value of a perfect smile applies to almost any situation. Don’t you want to nail that next interview, impress your love interest or feel confident in the next family photoshoot?

But what makes a perfect smile? Your teeth.

Various things can stain teeth and some can be removed. But is there a better alternative than going to the dentist?

That’s the motivation behind the lucrative market of whitening strips. But do they actually work? Crest Whitening Strips are favorite options for many consumers but will they work for you? We’ll help you find out.

What Are Crest Whitening Strips?

Inside a Crest box, you’ll find small, flexible strips coated with a substance that’s meant to whiten the teeth. This happens when the chemicals remove:

  • Stains on the surface
  • Stains below your teeth’s enamel

Peroxide is a main component of the whitening process as well as:

  • PVP
  • Peg-8
  • Acrylates Copolymer
  • Sodium Hydroxide
  • Sodium Saccharin

You place one strip on each row of teeth and leave them on for 30 minutes at a time. (Note that the brand has different products and timelines may differ depending on the strength of the particular item). You can use them daily for the best effects.

The strips mold to the shape of your teeth so the chemicals can reach all surfaces. This also makes it possible to still speak and even drink water while you wear them. After a half hour session, you simply peel them off.

Note that they’re not reusable.

Do The Strips Work?

The brand’s research gives you the following stats:

But here’s what’s important: The effects are situation dependent in terms of timelines and results. You’ll have your own unique experience.

How Fast Do They Work?

There’s no telling how your teeth will respond to this treatment since your staining and coloring are unique. You may see results as soon as after two treatments. However, some users need to use an entire box of strips (they’re available in boxes of 14 or 21 treatments). And unfortunately, they don’t always work.

Note, that it’s easy to see the changes on much-stained teeth. If your teeth are relatively white already, the difference will be harder to notice.

Who Do They Work For?

Are the stains you have relevant to what Crest strips are designed to do? The strips can mostly help with stains caused by:

  • Coffee
  • Wine
  • Smoking

For other problems—such as fluoride levels or stains caused by medication—you may need more professional, cosmetic help.

What are the Risks?

Even with these small strips, you’ll come across a few risks which may influence your decision of whether you’ll try them out.

Risks to Teeth

Note that some harsh chemicals are used—such as peroxide—which can be harmful to your body. Though whitening is the common effect, some users’ teeth can become stained even though it doesn’t result in structural damage to enamel or teeth.

Some people also complain of a toothache though this can be related to ineffective tooth hygiene. The chemicals in the strips may enhance existing problems.

Risks to Gums

Because the chemicals are bound to travel onto your gums, be prepared to experience:

  • Sensitivity
  • Irritation

It should disappear when you stop using Crest Whitening Strips and note that the brand does have products for sensitive users too.

The one comfort of using Crest strips is that this brand is the only one approved by the ADA (American Dental Association). This could mean that using this brand is safer than most similar products. Ready to give them a try?
