How to Choose Teeth Whitening Products

May 26 2020

With dozens of products on the market, choosing the best product for teeth whitening at home can seem like a daunting task. So, what's the good news? It doesn't have to be overwhelming or difficult. You can narrow down your choices by looking at different aspects of each product until you land on the best teeth whitening product that suits your needs as well as your lifestyle.

What are the Ingredients?

The first thing you want to know is what's in the whitening gel and where was that gel made.
The best teeth whitening product will have ingredients readily listed on their website or product packaging for your review, including where the gel is manufactured. You'll want to make sure that the gel is made in a country you trust.

Look for active ingredients that have been proven to be both safe and effective, keeping in mind that hydrogen peroxide is a top choice. Hydrogen peroxide is proven both safe and effective for teeth whitening. When used as directed at safe levels of concentration, it will not damage tooth enamel and it breaks down safely into oxygen and water molecules in your mouth.

Hydrogen peroxide is the active ingredient in GLO Lit Teeth Whitening Vials with a special formulation that adheres to your teeth and penetrates as it whitens. Just brush the gel on your teeth and go about your day. (No messy strips needed, and you don't even have to rinse!)

Many companies use carbamide peroxide, which can be effective, but it is not without notable drawbacks. Carbamide peroxide breaks down into urea and ammonia inside your mouth, and all we can say to that is yuck.

Companies choose carbamide peroxide because it's more stable than hydrogen peroxide, meaning it doesn't break down as quickly when exposed to air. This means that it doesn't require a special delivery system, which would be more expensive. GLO Science's whitening gel is packaged inside patented GLO Vials, which were designed by the company especially to keep the hydrogen peroxide whitening gel fresh and active, even after they are opened.

Carbamide peroxide is also less effective than hydrogen peroxide in equal concentrations. Because carbamide peroxide doesn't break down as quickly as hydrogen peroxide does, it requires longer contact time with the teeth in order to whiten. It also requires three times the concentration of hydrogen peroxide (so you would need 18% carbamide peroxide whitening gel to be equivalent to a 6% hydrogen peroxide whitening gel).

A number of other so-called "active" teeth whitening ingredients may also show up in different gels, but those ingredients often aren't proven to actually be effective. Look up published, peer reviewed studies from a trusted source if you're ever in doubt as to how effective and safe an active whitening ingredient is.

Does it Cause Sensitivity?

Sensitivity is the most common complaint people have with teeth whitening. Sensitivity can be caused by a number of factors. Biology is one of those factors, as some people are simply more prone to have sensitive teeth. Additional factors include the condition of the teeth and gums, whitening gel ingredients, contact time with the teeth, and whether or not the gel runs onto the gums or soft tissue.

Look for teeth whitening products that are specially designed and formulated to minimize or eliminate sensitivity, like those from GLO Science. Whitening gels that include Potassium Nitrate are less likely to cause sensitivity because it acts as a desensitizer. A thick whitening gel that sticks to the teeth, instead of a drippy gel that can run all over your gums, is also less likely to cause sensitivity.

This is also where the whitening technology comes in. A mouthpiece that uses both gentle warming heat and LED light will allow you to amplify the whitening results of the gel in a relatively short period of time. GLO teeth whitening devices are the only ones to use this patented heat and light technology so the gel is only on your teeth for eight minutes at a time. Teeth whitening products that require you to wear the gel for many minutes or even hours at a time are much more likely to cause sensitivity problems.

Will it Fit into Your Lifestyle?

Unless you can afford to spend hours sitting idle with a product in your mouth, you'll want to look for a teeth whitening product with features that work with your routine:

  • Easy to use
  • Allows you to multitask while whitening
  • Has a manageable treatment time

The full recommended treatment time is based on four factors: contact time, strength of the gel, acceleration by heat and repetition. Both the GLO Brilliant Teeth Whitening Device and GLO Lit use LED light and warming GLO heat to accelerate the hydrogen peroxide whitening formulation for easier, faster and more effective whitening. Application time is just eight minutes, and the hands-free device lets you easily include whitening as part of your regular morning or evening routine.

Will It Provide Your Desired Shade ?

Some products may be designed for intense whitening, while others are good for occasional touch-ups. The best product for teeth whitening at home gives you both options in one.

If your teeth are pretty white and you just need a touch-up now and then, you can probably use GLO Vials, which you simply brush onto your teeth without the need for messy strips or inconvenient trays. For a more complete whitening treatment, you can amplify the whitening gel by using it with the GLO device for a full five to seven days. You can follow this with another five to seven days of treatment if you want even whiter teeth.

Even after a complete treatment, whitening is not a one and done deal. No matter how effective, no system will give you permanent results that last forever. You'll need maintenance and regular treatments to keep your teeth white, so you want to make sure you're getting a good value for your money. The best teeth whitening products are high-quality devices that last through numerous treatments. .

Can You Trust the Brand?

You might see a lot of celebrities using different products online, but that's not necessarily proof of anything. Celebs get paid to create those posts and ads, so all that means is they agreed to a money-making deal. Maybe they researched it, maybe they didn't, but you definitely should so you know you're treating your smile right.

Things you want to look for include:

  • Who developed the system? Was it invented by a practicing dentist who understands the science and safety concerns of whitening, or was it just sourced from a generic factory somewhere?
  • Where is it sold? Is it sold at trusted retailers, or is it only available direct from the company?
  • Is the brand used by dental practices and trusted by dentists?
  • Do the brand's satisfaction policies just give you more gel if you aren't happy, or will they refund your money if there is a problem?

For the record, the GLO device was created by a practicing dentist, is used and trusted by dentists and sold at trusted retailers as well as direct from GLO Science. The device also comes with a 30-day money-back guarantee and one-year limited warranty to boot.

Now that you know how to choose teeth whitening products, your choice should be that much easier to make. The GLO device and GLO V ials meet all the above criteria to come in as the best product for teeth whitening at home, hands down. Shop GLO Science for yours now.
