Teeth Whitening Strips: The Basics

What Are Teeth Whitening Strips?

Teeth whitening strips are thin, flexible plastic strips with a layer of peroxide-based whitening gel on one side. They are designed to gradually remove stains and discoloration from your teeth.

They’re a popular at-home solution for stained teeth caused by coffee, tea, or smoking. They’re also an affordable alternative to expensive in-office whitening treatments.

How Do You Use Whitening Strips?

Using whitening strips is as easy as brushing your teeth or using teeth whitening mouthwash!

To apply the strips, just peel back the backing paper and firmly press them onto all surface areas of your top and bottom teeth. Make sure to keep the gel side against your teeth for the best results.

Leave the strips on for as long as it says on the packaging—usually around 10-30 minutes. Then peel them off and marvel at the results!

But what happens if you swallow teeth whitening strips? No need to worry too much. At worst, your stomach feels a little funny. At best, you’ll get white teeth. 

Most people ask: “Should you dry your teeth before applying whitening strips?” Based on our hands-on experience, drying your teeth beforehand helps the gel stick better and provide more even coverage. That’s why drying your teeth before applying white strips using a clean towel or washcloth works wonders.

But are teeth whitening strips permanent? No, teeth whitening strips aren’t permanent. Even the best whitening strips, like the Magic Teeth Whitening Strips, don’t last forever. You have to use them again if your teeth darken or yellow over time.

Learning how teeth whitening strips work is important. They’re designed for easy use, and you’ll already see results after one treatment. With precision and patience, you can get your teeth looking phenomenal!

How Long Does It Take Before You See Results with Teeth Whitening Strips?

Consider this to see results after using teeth whitening strips: 

Ingredients Matter

Ingredients play a big role in how quickly you see results. Look for strips containing hydrogen peroxide or carbamide peroxide. Drawing from our experience, they’re the two most effective ingredients in teeth-whitening products. They break down into oxygen molecules, penetrating your tooth enamel and removing discoloration.

The best teeth whitening strips, like Sensitive Snow Strips™ Dissolvable Teeth Whitening Strips With Snowactives, also contain hydroxyapatite, a naturally derived mineral that promotes enamel remineralization.

Risks And Precautions

There are some risks associated with teeth whitening products, like:

Tooth-Colored Restorations

What about putting in dental restorations or you already have them? Do whitening strips work on bonded teeth? Do you have to whiten your teeth before getting a crown

Unfortunately, whitening strips don’t work on bonded teeth because they’re primarily designed to whiten natural teeth. That’s why you also have to whiten your teeth before getting a crown to avoid a patchy whitening effect. 

Bleached Gums

All gums aren't created equal, so what may be a whitening bonanza for some could cause irritation for others. 

Using strips that don't fit quite right or applying too much pressure can result in "bleached" gums—an unpleasant stinging or burning sensation. 

To avoid this, follow the instructions on the label and don't force the strips onto your teeth.

Splotchy Whitening (Spots On Teeth)

Bad news for coffee and tea enthusiasts: your favorite beverages give your teeth a distinct flair for the dramatic, leading to uneven staining. In some cases, teeth whitening strips can magnify these theatrics, creating splotchy whitening patterns. Don't despair, though. Spots usually even out eventually, so long as you keep up your whitening routine.

So, after contemplating the precautions and pitfalls, how long does it take for teeth whitening strips to work? 

Most products advertise visible results after three days, but the full whitening effect may take 14-21 days depending on factors like tooth staining severity, strip concentration, and your intrinsic tooth color.

Is Follow-Up Care Necessary at Home After Using Teeth Whitening Strips?

Absolutely! Teeth whitening strips are a great way to brighten your smile, but once you've reached the desired level of whiteness, always do follow-up care at home. 

This includes brushing with a whitening toothpaste at least twice daily, flossing regularly, avoiding certain foods and drinks that stain teeth like coffee, tea, and red wine, and not smoking or chewing tobacco products.

There are also other products that help enhance and maintain your newly whitened teeth, including:
