How can I figure the expiration date?

Our products are manufactured and packaged fresh, within 2-3 weeks of the date of your purchase.
It is safe to assume that you have at least 11 more months after the purchase date. This period can be 23 months if you keep the gels in your fridge – not the freezer.
It is hard to put a specific expiration date on the product, because it  depends on the storage conditions.
Even if they expire, they are not harmful, so there is no need to worry about using expired gels. An expired teeth whitening gel loses the whitening ability and turns into water with a lot of oxygen molecules inside. Keep using your whitening products until they turn into water.

How often should I use the product?

This really depends on your comfort level and sensitivity.

The best way to whiten your teeth would be the slow and steady process. Start slowly and with short sessions.  There is no rush and you have a lot of gel that will last a year.

After your first whitening session, wait for a 24 hour period and if you do not feel any sensitivity you can do another session.

We do not recommend back to back sessions for more than 3 days even if you feel comfortable. Your gums need some time to tolerate the treatment.

 

 

What do I do when I’m done with the process? Do I rinse the gel off or leave it on?

After the whitening process, please take off the trays and rinse your mouth thoroughly.  Use your finger tips to get any residual gel on your teeth or on your gums. You can brush your teeth very lightly.  If you leave any gel on your teeth, it will continue working and that may cause sensitivity.

You should also clean your trays for your next session.

Stay away from staining food and drinks for 24-48 hours.  If you must consume some, brush your teeth immediately.

 

 

I ordered “Cool Teeth Whitening” which is 44% Carbamide Peroxide but the ingredients list has Hydrogen Peroxide

Hydrogen Peroxide is the main active ingredient of Carbamide Peroxide.  The ingredients list has only the very basic elements, one of them being hydrogen peroxide.  Hydrogen peroxide is combined with other elements and becomes Carbamide Peroxide.
The amount of hydrogen peroxide used and the way it is combines determines the % off the carbamide peroxide.
In summary:
Carbamide peroxide contains hydrogen peroxide at a ratio of 1:3.  For example, a product with 44% carbamide peroxide has about 15% hydrogen peroxide.

I used the whitening products, but 2 days later my teeth are yellow. What happened?

Most probably you consumed staining foods and drinks right after the whitening process.  According to the teeth whitening experts, the first 24-48 hours after teeth whitening is critical. After the whitening process, the pores or dental tubules on your teeth are open and they are very susceptible to staining. You should give your teeth a chance to recover before consuming food and beverages that may stain your teeth. Anything that stains your white shirt will stain your teeth. You may want to wait at least 36-48 hours to consume food or beverages that may stain teeth, such as coffee, tea, green tea, wine, etc. Maintenance with at-home trays is very important to keep up the whiteness.
