What is Supersmile?

Supersmile is a brand of at-home oral care products and whitening toothpastes.

The founder, Dr. Irwin Smigel, is the “father of aesthetic dentistry” who created the company 40 years ago. 

All of the products are made with safe, clean ingredients that are gentle on your teeth. The whitening formula does not contain any harsh abrasives (that can cause sensitivity) or silica, which scratches tooth enamel and makes it porous.

Supersmile has 15 different whitening toothpastes to choose from, which means they have a product to fit every need. For example, if your teeth are severely discolored, you can buy the extra strength whitening toothpaste. 

If you are just looking for a daily whitening toothpaste for upkeep, many other options are available. Supersmile also has fluoride-free options and all-in-one kits. 

How Do Teeth Become Discolored?

Tooth discoloration is a normal part of aging, and teeth can stain for many reasons.

The most common way is from consuming dark-colored foods and beverages like coffee, red wine, tea, curry powder, tomato sauce, and berries. Thinning enamel, tooth injuries, and medications (certain antibiotics) can also cause discoloration. 

Fortunately, there are many at-home and professional whitening treatments available to fix these issues. Supersmile is a great option if you are looking for an affordable, quick, and effective way to whiten your teeth at home. 

How Does Supersmile Whitening Toothpaste Work? 

All of Supersmile’s products whiten teeth and improve enamel strength. They are also packed with ingredients that remineralize enamel and dissolve bacteria, biofilm, and plaque to keep your smile healthy and cavity-free for years to come.

In addition, every product is vegan, kosher, cruelty-free, and BPA-free. They are never made with silica, parabens, sulfates, known allergens, animal by-products, or charcoal. 

Supersmile does not use silica because it is a harsh and grainy abrasive that damages tooth enamel. Instead, they use Calprox®, a safer and less abrasive substance capable of removing deep stains.

Supersmile products are 75 to 94% less abrasive than the limit set by the American Dental Association (ADA). 

Lastly, many of the whitening toothpastes are sweetened with Xylitol, a sugar alternative that is actually beneficial for teeth health. Studies have shown that Xylitol can inhibit plaque and suppress decay-causing bacteria.2, 3 The sugar alternative is also sucralose-free, preservative-free, and vegan. 

What is Calprox? How Does it Whiten Teeth?

Supersmile's oral care product line is the first to include Calprox®, a proprietary form of calcium peroxide. This ingredient works by dissolving protein pellicles on teeth (a thin layer of protein that attracts plaque, bacteria, and stains). By removing this layer, your teeth are left looking and feeling cleaner for a longer period.

One study found that patients treated with calcium peroxide showed improved enamel hardness, color, and calcium uptake compared to conventional whitening agents.1, 4

Is Calprox Safe on Dental Restorations?

Calprox is safe to use on bonding, laminates, dentures, and veneers, among others. However, these restorations will not whiten like your natural teeth. 

How Often Should You Brush With Supersmile Toothpaste? 

Supersmile recommends using the whitening products twice a day. Brush your teeth for at least two minutes when you wake up and two minutes before bed. 

How Does the Subscription Service Work?

Supersmile offers a subscription service where you can get your favorite products delivered straight to your door every one, two, or three months. You can cancel this service at any time.

Review of Supersmile’s 5 Best Selling Toothpastes

Based on our research, here are five of Supersmile’s best selling whitening toothpastes: 

Professional Whitening Toothpaste 

Best Overall (Editor’s Choice)
Waterpik Sonic Fusion

This is Supersmile’s original whitening formula. Developed 40 years ago, the whitening toothpaste can still lighten teeth up to six shades in five days (on average). 

It contains Supersmile’s unique Calprox® formula to gently whiten and clean teeth without sensitivity. The Professional Whitening Toothpaste also goes through a 72-hour production process (versus about three hours for traditional toothpaste). This ensures quality is kept high. 

This toothpaste is safe to use every morning and night. It also remineralizes and restores enamel, effectively removes plaque, and is 75% less abrasive than the ADA’s limit (it scores a 65 on a scale of 0 to 250). 

Relax Whitening Toothpaste | Hemp

Best Overall: 1st Runner Up
Waterpik Sonic Fusion

The Relax Whitening Toothpaste is similar to Supersmile’s original whitening formula except with added ingredients like hemp, melatonin, valerian, and other calming herbs. These ingredients work together to provide relaxation, making this toothpaste a perfect addition to your nighttime routine.

The formula is designed to supercharge your senses and provide a minor ‘buzz’ that is 100% safe and healthier than coffee. 

Awake Whitening Toothpaste | Caffeine

Best Overall: 2nd Runner Up
Waterpik Sonic Fusion

The Awake Whitening Toothpaste contains all of the same ingredients as the original toothpaste but with added ingredients like green tea, caffeine, matcha, and other naturally energizing ingredients. 

Fluoride, calcium, and phosphates help build enamel strength while protecting your teeth against cavities. Like the original toothpaste, this product is also 75% less abrasive than the ADA’s limit (it scores a 65 on a scale of 0 to 250). 

This toothpaste is fluoride-free but includes calcium and phosphates to help build additional enamel strength and prevent cavities. 

Extra White Premium Set

Best Bundle Option
Waterpik Sonic Fusion

Supersmile’s Extra White Premium Set includes two powerful whitening products. The first is a high-performing professional whitening toothpaste. The second is an accelerator formula with triple the Calprox®, which safely and effectively brightens and remineralizes teeth without sensitivity.  

The Extra White Toothpaste gently dissolves the sticky biofilm on your teeth where plaque, stains, and bacteria accumulate.

The Extra White Accelerator removes deep stains on teeth and below the enamel, providing lasting whitening results.

The whitening toothpaste and accelerator are 94% less abrasive than the ADA’s limit. 

Extra Whitening System - Deluxe Travel

Best Bundle Option
Waterpik Sonic Fusion

This set includes travel-sized versions of Supersmile’s Extra Whitening Toothpaste and Whitening Accelerator. These products have been shown to whiten teeth up to nine shades within 30 days (with minimal to no sensitivity). 

The Extra Whitening Toothpaste also includes an added boost of calcium, phosphates, and fluoride to strengthen enamel even more (and prevent cavities) on the go. 

When used as directed, this TSA-approved set provides you with a 3-month supply of whitening.
