Do You Brush Your Teeth After Whitening Gel?

It is completely safe to brush your teeth after using a whitening gel and it should not impact the effectiveness of the treatment. For best results, it is recommended to brush your teeth prior to using even the strongest teeth whitening gel. When you brush your teeth after a whitening treatment, be gentle and use a soft bristle brush to avoid irritating your gums.

What Is The Strongest Hydrogen Peroxide For Teeth Whitening?

Are you stressing over deep set-in stains on your teeth from years of drinking coffee, wine, soda, or simply living life? Rest assured, hydrogen peroxide teeth whitening gel can erase all of this and more. Even the strongest teeth whitening gel should contain no more than a 10% hydrogen peroxide in order to protect your pearly teeth. You might be wondering if simply buying a bottle of hydrogen peroxide will do the trick. While your average store-bought bottle contains an average of 3% hydrogen peroxide, making it safe to swish around in your mouth, you don’t want to risk swallowing it as it can cause damage to your throat and esophagus. Your best bet is to use a teeth whitening gel that contains hydrogen peroxide.

Does Teeth Whitening Gel Expire?

Most teeth whitening gels expire within a year of purchasing them. Over time, hydrogen peroxide breaks down and dissipates. Without this key ingredient the gel will not provide the results you are looking for.

What Percentage Of Hydrogen Peroxide Is Best For Teeth Whitening?

According to the American Dental Association, hydrogen peroxide teeth whitening gel that utilizes up to 10% peroxide concentrations are considered safe. If you use a solution that contains more than 10% hydrogen peroxide you are at risk of damaging the protective enamel on your teeth - and once that’s gone there’s no getting it back. That’s why it’s so important to use a reputable and safe teeth whitening gel.

How To Use Teeth Whitening Gel?

From teeth whitening pens to teeth whitening trays, the exact usage directions for teeth whitening gels vary from product to product. Always be sure to follow the manufacturer guidelines carefully for best results.

What Is The Strongest Teeth Whitening Gel Percentage?

Hydrogen peroxide offers the strongest teeth whitening gel when compared to carbamide peroxide, not because of percentages per say, but because hydrogen peroxide breaks down quicker than carbamide. Typically, hydrogen peroxide will break down and release the majority of its whitening power in just thirty to sixty minutes. By comparison, carbamide peroxide only releases 50% of its whitening agents within two hours and will continue to release additional whitening power for as long as six hours. Therefore, if you were to use carbamide peroxide you would have to leave the teeth whitening gel on for much longer to yield the same results.

How Long To Leave Teeth Whitening Gel On?

This question is subjective to the exact product you are using. We are all pressed for time so shorter is obviously better when it comes to how long you need to leave a product on your teeth. That’s why GLO Science uses innovative technology to whiten teeth in short 8 minute sessions.

How To Tell If Whitening Gel Is Expired?

First, check the use by date. If the product does not have one, a key indicator that teeth whitening gel has expired is if it appears cloudy or foggy in color. This means it has oxidized and is therefore expired.

What Strength Of Hydrogen Peroxide Do Dentists Use?

Most American dentists use gels that contain between 10 - 40% hydrogen and carbamide peroxide, further activated by light technology. This is why the best and strongest teeth whitening gels are available through your dentist.

Does Saliva Ruin Teeth Whitening Gel?

It is highly unlikely that your saliva will dilute teeth whitening gel, even if you experience a build up of spit while applying the solution- this is completely normal!

What Happens If You Swallow Teeth Whitening Gel?

While you wouldn't want to swallow hydrogen peroxide, swallowing some teeth whitening gel is perfectly safe. When using our whitening gels you may continue to swallow as you normally would, making the process as easy and comfortable as possible.

Can I Put Whitening Gel In My Invisalign Trays Or Retainer?

You do not want to put whitening gel on your Invisalign trays or retainer. It might seem like a good idea in theory, but using your liners or trays as a whitening device aid will not provide the best results. Most liners end below the gum line and lack a tight seal, allowing the gel to escape and mix with saliva. Along with lackluster results, you may also experience burning gums.

Can You Leave Teeth Whitening Gel Overnight?

No, you should not leave teeth whitening gel on overnight. Not only could this damage your teeth but there’s no benefit to doing so. Hydrogen peroxide teeth whitening gel works within a much shorter period of time, especially when paired with warming lights.

Can I Close My Mouth With Whitening Gel?

You can close your mouth, swallow and act as you normally would while the whitening gel goes to work breaking down stains and discoloration.

Can Teeth Whitening Gel Damage Gums?

It is always possible for teeth whitening agents to irritate your gums, usually this irritation is only temporary and is often a result of misuse or overuse.
