In this video, Dr. Yazzi shares why our antioxidant-powered formulas are designed to support gum health, comfort, and long-term wellness — without harsh ingredients or unnecessary fillers.

A novel approach to teeth whitening

Our teeth whitening products combine potassium nitrate with carbamide peroxide. The former is for teeth sensitivity, and the latter is the gold standard for teeth whitening. Its whitening effect is further enhanced by the use of blue and red LED light – for teeth that will appear brighter almost immediately! To minimize tooth sensitivity, our teeth whitening products contain a low yet highly effective concentration of potassium nitrate. But if you are particularly sensitive to teeth whitening, try our pre-treatment routine to further reduce tooth sensitivity. For the complete package, combine our LED2 teeth whitening system with our post-whitening oral care system for maximum oral health and your brightest smile. Enjoy free domestic shipping and a 10% discount on your first order. Plus, if you subscribe, you'll receive a 15% discount on all future orders.

Maintaining the effects of teeth whitening treatments

Our post-teeth whitening products are designed to boost whitening treatments to last longer. They contain ingredients known to have antibacterial and antioxidant properties to provide a natural approach to soothing your teeth and gums after teeth whitening.

To better maintain your brighter smile, try our post-whitening oral care system, formulated to enhance teeth whitening by lifting stains, polishing teeth, and freshening breath. Free of alcohol, sodium lauryl sulfate, parabens, and artificial sweeteners, it contains powerful antioxidants like phloretin and ferulic acid that support and nourish your oral tissue.

Our post-whitening toothpaste gently polishes and thoroughly cleans surface stains while removing unhealthy build-up, helping you keep your teeth whiter for longer. Follow it up with our post-whitening mouthwash that soothes oral tissues after whitening procedures, freshens breath, and boosts whitening treatments to last longer.

Why use pre- and post-whitening treatments?

A key ingredient in whitening treatments is carbamide peroxide. The way it works is that, upon coming into contact with your teeth, it releases free radicals that break down organic compounds staining the surface of your teeth. While this helps to whiten your teeth, it has the unfortunate side-effect of burning your gums and causing teeth sensitivity.

And that’s where our pre- and post-whitening treatments are so helpful. Antioxidants neutralize free radicals. Our teeth whitening pre-treatment and our post-whitening oral care system are specially formulated and contain powerful antioxidants – like phloretin and ferulic acid – that put a stop to pain or sensitivity induced by free radicals.

Our post-whitening maintenance products not only extend the effects of whitening treatments, they also soothe and refresh your mouth.

    Why Are My Teeth So Yellow? Causes And Treatments

    Teeth naturally have a white-yellow hue to them. This is because the enamel, the protective layer outside your teeth, is white, but can be thinner for some people and even translucent. The layer directly under the enamel is light yellow. Therefore, it is perfectly natural to have a light yellow color on your teeth, and it is not caused by poor oral health.

Frequently Asked Questions

+ What do dentists recommend to whiten teeth?

There are a lot of products available in supermarkets that claim to whiten teeth. Often, they contain a high percentage of hydrogen peroxide or carbamide peroxide. While both whiten teeth, they can also cause pain, sensitivity, and even damage to your teeth’s enamel in high concentrations. This is why our specially formulated teeth whitening products contain a low yet effective concentration of carbamide peroxide. They also contain potassium nitrate, for teeth sensitivity. Read our teeth whitening guide to learn more.

+ Can yellow teeth become white?

Are yellow teeth bad? Not necessarily, no. Teeth naturally have a whitish yellow tint – this is because the layer under the enamel is yellow. That being said, teeth can become darker yellow as a result of various factors, such as diet, smoking, and poor oral hygiene. There are plenty of ways by which you can get rid of excessively yellow teeth. You can visit the dentist to ask about whitening treatment, or you can try dentist-recommended teeth whitening products such as our whitening kit.

+ Why do my teeth hurt after a whitening treatment?

The key ingredient in teeth whitening treatments is hydrogen peroxide or carbamide peroxide. The higher the concentration, the quicker the whitening action. However, high concentrations cause greater pain and sensitivity in your teeth and gums. The highest concentration peroxide gels are found in dental clinics, and require a rubber dam to protect the soft tissue of your mouth from the gel. This is why our whitening kits contain lower, yet still effective, concentrations of carbamide peroxide, along with potassium nitrate for teeth sensitivity. If you are experiencing discomfort after a teeth-whitening treatment, we recommend our clinically proven sensitive toothpaste, or our post-whitening oral care system to alleviate your symptoms.

Can I use your whitening pre-treatment before professional or at-home whitening kits?

Yes. For optimal sensitivity relief, use our whitening pre-treatment for 3 days prior to your whitening treatment. We recommend the pre-whitening treatment first thing in the morning, after lunch, and before bed.

What’s included in the Whitening Oral Care System?

The system includes a trio of products - our Post-Whitening Toothpaste, Teeth-Whitening Mouthwash, and our AO ProVantage Dental Gel. The trio work together to offer maximum whitening benefits that go beyond simple cleaning to brighten teeth, extend your whitening results, and nourish your oral tissues.

Will these products help if I already have sensitive teeth after whitening?

Yes, absolutely. Our Post-Whitening Toothpaste includes nano-hydroxyapatite and potassium nitrate, both of which are shown to reduce sensitivity following bleaching procedures. Plus, the whole system uses non-abrasive, peroxide-free ingredients to remove stains gently.

Can I use these products daily even if I’m not actively whitening my teeth?

Yes, they are intended for daily use, twice a day. Our teeth whitening products help maintain your brightest smile by fighting surface stains and include maximum fluoride to fight cavities and strengthen teeth.
