Eco-Dent toothpaste- tested and recommended

May 27, 2010 Reviewed by Marta 0 Comments
I have been blessed with having teeth that are naturally on the white side. Still, I have noticed with the passing years that they are losing their luster and this is not something I am going to let pass. Yellow teeth look old and age the rest of the face. My Philips Sonicare Toothbrush has been an absolute godsend and now I may have found a toothpaste to compliment it, Eco-Dent Res-Q-Dent ($8.99).

This toothpaste is aimed at those with sensitive teeth, which I don't have (mostly because the Philips does such a good job of keeping my gums healthy). But a sample of Res-Q-Dent arrived unsolicited and, as you can never have too much toothpaste, I started using it when my tube of Kiss My Face ran out. It turned out to be surprisingly good at whitening my teeth and enjoyable (that may be too strong a word, this is a toothpaste after all) to use.

Potassium nitrate used at a 5% concentration is the active ingredient for desensitizing teeth and there is research that suggests that a potassium nitrate toothpaste could help mitigate against discomfort caused by using teeth whiteners in tray or strip form. According the study, which used a 5% concentration of potassium nitrate, it blocks the action of the intradental nerves and decreases the perception of pain.

The whitening agent is baking soda and it gives Res-Q-Dent quite a strong taste of it (which I don't particularly mind). Grapefruit seed extract is included to prevent bacteria and infections, while research backs up aloe as a dental friendly ingredient. The study, published in General Dentistry, the Academy of General Dentistry’s peer-reviewed journal, looked closely at the use of aloe vera gel as an active ingredient to cleanse and soothe gums, as well as its use in toothpaste to help fight cavities.

Best of all, there is nothing nasty in Eco-Dent's Res-Q-Dent. Safe, non-toxic thickeners like carboxymethyl cellulose have been chosen and mild surfactants like sodium cocoyl glutamate. The only thing that is less than squeaky clean is sodium lauroyl sarcosinate, which should not be used in cosmetics and personal care products in which N-nitroso compounds may be formed.


Potassium Nitrate 5.0%, Sorbitol, Glycerin, Sodium Bicarbonate, Kaolin Usp, Carboxymethyl Cellulose, Sodium Cocoyl Glutamate, Sodium Lauryl Sarcosinate, Xylitol, Stevia Extract, Grapefruit Seed Extract, Aloe barbadensis Leaf Juice, Purified Water, Hydrated Silica, Menthol, Spearmint Oil, Sodium Ascorbate, Calcium Ascorbate, Boron Citrate, Zinc Citrate.
