Two Important Teeth Whitening Ingredients

Teeth Whitening Ingredients Carbamide Peroxide and Potassium Nitrate Fluoride

There are numerous active ingredients in a tooth whitening gel (Serum).

A few well-known ingredients are Carbamide Peroxide and Hydrogen Peroxide.

What are these ingredients and are they safe?

What are the ingredients in the Celebrity Smiles teeth whitening products compared to other teeth whitening products?

When you continue reading, as a dental hygienist, founder of Celebrity Smiles, former clinical USC dental school professor and preventive care specialist, I will answer these questions. 

Teeth Whitening Ingredients

What are the Main Ingredients in the Celebrity Smiles Teeth Whitening Products?

The main ingredient in Celebrity Smiles Teeth Whitening Products is 35% Carbamide Peroxide.

The second and unique ingredient to tooth whitening gels (Serum) is 6% Potassium Nitrate Fluoride.

Keep reading and I will explain why these ingredients are important to your dental health and prevention of tooth sensitivity.

Carbamide Peroxide Teeth Whitening Ingredient

  1. Carbamide Peroxide

Carbamide Peroxide is a water-soluble compound and it has many applications.

It works to sanitize and it can also remove earwax to treat infections. It is also very popular for whitening teeth.

Carbamide peroxide doesn’t bleach your teeth but it dissolves stains on your teeth to help brighten your smile.

Carbamide peroxide is only partially made of hydrogen peroxide, it doesn’t oxidize (breakdown into Oxygen) as quickly as pure hydrogen peroxide. As a result, hydrogen peroxide releases most of its whitening power within the first half-hour to an hour of use, while carbamide peroxide can continue to release whitening power for up to 8 hours.

Because Carbamide Peroxide breaks down more slowly, we have found (we’ve been selling this formula to dental offices for over 10 yrs.) it is less likely to cause tooth sensitivity and it tends to work longer on your teeth.

For example, after you have used your Celebrity Smiles LED mouthpiece you will notice your teeth continue to whiten for hours after you have removed your mouthpiece.

You think your whitening session is complete but the serum applied to your teeth continues to work for hours after your whitening session.

For this reason, Carbamide Peroxide is an excellent ingredient to consider for your whitening treatments.

Is Carbamide Peroxide Safe for Tooth Enamel?

Carbamide peroxide is considered safe. Carbamide Peroxide breaks down into hydrogen peroxide and urea which is a naturally occurring protein in humans.

Urea is safe to swallow and usually does not cause harm. Please do take into consideration that it is crucial to use the correct dosage and application to prevent side effects. Always read the user guide enclosed in your Celebrity Smiles teeth whitening kit. We also have a section on our website that you can read the “How to Use” instructions.

Teeth Whitening No Sensitivity Potassium Nitrate Fluoride

  1. Potassium Nitrate Fluoride

Potassium Nitrate is a salt of the potassium ions K⁺ and nitrate ions NO₃⁻and is therefore an alkali nitrate. It occurs in nature as a mineral, niter. It is a source of nitrogen, and nitrogen was named after niter. 

Why is Potassium Nitrate Used?

Potassium nitrate decreases the fluid flow through the tubules (microscopic pores inside the enamel of your teeth) by plugging them, (imagine placing a fur coat over each tooth) decreasing the level of activity of nerve inside your tooth and this reaction prevents or reduces the sensation signals (That ZING!) from reaching the brain.

Also note that potassium serves as a companion to magnesium in the body's efforts to regulate your blood acidity. When your blood becomes too acidic, these acids can remove calcium from your teeth and jawbone, weakening them. A diet rich in potassium can, therefore, help your teeth and bones use calcium more efficiently.

Potassium is part of Potassium Nitrate Fluoride and this does help to build strong teeth and bones. One of these bones is the jawbone.The jawbone is what holds your tooth in place.

Hydrogen Peroxide Teeth Whitening Ingredient

Hydrogen Peroxide Vs. Carbamide Peroxide for Teeth Whitening

Both hydrogen peroxide and carbamide peroxide are considered very safe when used as directed.

Most dental offices use Carbamide Peroxide because it will breakdown more slowly and there is less chance of tooth sensitivity.

We have had amazing clinical results from customers who used the combination of 35% Carbamide Peroxide and 6% Potassium Nitrate Fluoride.

 The Carbamide Peroxide does continue to whiten your teeth for hours after you have completed your teeth whitening session with the LED mouthpiece. The Potassium Nitrate Fluoride does seal the microscopic pores inside your enamel so our customers never experience tooth sensitivity.

If you do experience tooth sensitivity using the Celebrity Smiles ingredients, there is most likely a different dental issue occurring and you should schedule an appointment with you dentist.


Teeth whitening has gained huge popularity since the pandemic of 2020. If you are looking for a safe way to whiten brighten your smile without causing tooth sensitivity, consider Celebrity Smiles whitening formula which are dental-grade ingredients.
