MAXIMUM TEETH WHITENING IS THE BEST AT HOME TEETH WHITENING SYSTEM AVAILABLE. HERE'S WHY... Convenience . Unlike many teeth whiteners on the market, Maximum Teeth Whitening only requires 15-30 minutes for an application rather than hours by most other at home teeth whitening kits. There are no animal byproducts used in our glycerin. We use only the very highest quality Kosher grade glycerin. Why Kosher? Studies have shown that animal byproducts can be harmful and irritating on the soft tissue. No fluoride. Most teeth whitening products have fluoride so that they can promote that ingredient to an uneducated market. Many people now know the truth about flouride and know to avoid it. Reduced teeth sensitivity. Our quality formula actually reduces teeth sensitivity. 22% carbamide peroxide and optimized ph formula for maximum teeth whitening performance. No propylene glycol. Virtually all other brands have this potentially harmful ingredient. The American Academy of Dermatologists have warned for more than 20 years that propylene glycol should be avoided due to a significant number of reactions and as a primary irritant to the skin even at low levels. We use natural orange oil. Maximum Teeth Whitening is made from a unique formula exclusively by Trusted Health Products, Inc. and the highest quality ingredients available. It cannot be found anywhere else. There are a lot of very cheaply made imitations on the market. This product is going in your mouth. It matters. .
