Reviews of Supersmiles 5 Best Selling Toothpastes

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

Supersmile Professional Whitening Toothpaste 

Best Whitening Toothpaste

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). 

The Supersmile Professional Whitening Toothpaste also goes through a 72-hour production process, ensuring high-quality.

This toothpaste is safe to use every morning and night. We chose Supersmile Professional Whitening as the best toothpaste because it:

  • Remineralizes tooth enamel with ADA-recommended fluoride as an active ingredient
  • Effectively removes plaque
  • Contains baking soda (sodium bicarbonate) for healthy gums and fresh breath
  • Is 75% less abrasive than the American Dental Association limit 
  • Comes in icy mint, green apple, mandarin mint, rosewater mint, jasmine green tea mint, Tahiti vanilla mint, or original mint flavor

Relax Whitening Toothpaste

Best for Bedtime

The Relax Whitening Toothpaste is similar to professional whitening but has calming ingredients like hemp, melatonin, and valerian. 

These ingredients help you relax, making this toothpaste a perfect addition to your nighttime routine.

Awake Whitening Toothpaste

Best for Morning

The Awake Whitening Toothpaste contains naturally energizing ingredients like green tea, caffeine, and matcha. The formula is designed to supercharge your senses and provide a minor ‘buzz’ that is 100% safe and healthier than coffee.

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

Extra White Premium Set

Best Bundle Option

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. 

Professional Extra Whitening System Travel Size

Other Supersmile Products

Aside from toothpaste, Supersmile makes a whole line of products to whiten teeth. These include:

How Does Supersmile Whitening Toothpaste Work? 

Supersmile’s products are formulated to give you a whiter smile and stronger teeth. They’re packed with ingredients that remineralize enamel and keep your smile healthy and cavity-free for years.

Clean Ingredients

All Supersmile whitening toothpaste products are made with safe, clean, gentle ingredients for your teeth. These toothpastes are:

  • Vegan
  • Kosher
  • Cruelty-free
  • BPA-free

Supersmile whitening toothpaste products don’t contain ingredients like:

  • Silica
  • Parabens
  • Sulfates
  • Known allergens
  • Animal by-products
  • Charcoal

Gentle Whitening

Supersmile whitening toothpaste gently whitens teeth without harmful bleaches, harsh abrasives, or silica. Unlike other toothpastes, Supersmile doesn’t use silica. This harsh and grainy abrasive damages tooth enamel. 

Supersmile products are clinically proven to be 75 to 94% less abrasive than the limit set by the American Dental Association (ADA).6 

Patented Formula with Calprox

Their patented formula contains Calprox®, a safer and less abrasive substance that removes surface stains without sensitivity. Calprox is a proprietary form of calcium peroxide. This ingredient works by gently dissolving the protein pellicle on teeth. 

The protein pellicle is a sticky film to which plaque, stains, and bacteria attach. Removing this thin layer leaves your teeth white and clean for longer. 

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


Supersmile whitening toothpaste is sweetened with Xylitol. This sugar alternative is beneficial for teeth health. It’s also sucralose-free, preservative-free, and vegan.

Studies have shown that Xylitol can inhibit plaque and suppress decay-causing bacteria.2,3
