Ingredients

Pureganic's Coconut Charcoal All-Natural Teeth Whitening Powder only contains three ingredients and the company is very transparent about them. They are organic mint oil for flavor, bentonite clay -- a mineral-rich clay composed of volcanic ash -- and activated charcoal. That last ingredient may raise alarm bells with some because some dentists have expressed concerns about the abrasive properties of activated charcoal and its potential to wear away tooth enamel. This can cause sensitivity and once enamel is gone, there's no getting it back.

This isn't guaranteed to happen to you, but it is something to be aware of before you purchase this product. If you have any concerns about using activated charcoal products on your teeth, consult with your dentist before doing so. You may prefer a less abrasive product if you intend to whiten your teeth often.

Effectiveness

Customers who have tried the Pureganic Teeth Whitening Powder have reported largely positive results, according to the reviews on the company's website. Sensitivity doesn't appear to be an issue for most users, so this product may be worth considering if you find traditional hydrogen or carbamide peroxide teeth whitening products too uncomfortable.

Pureganic's product has not been approved by the American Dental Association. Few teeth whitening products carry the ADA Seal of Approval because gaining approval is a long and often costly process.

Ease of Use

Using the Pureganic teeth whitening powder is as simple as brushing your teeth. It's not a replacement for toothpaste. The company recommends brushing with the teeth whitening powder for two minutes first and then following up with regular toothpaste to ensure your teeth are clean as well as pearly white. Most teeth whitening products require you to wear them anywhere from 10 minutes to 30 minutes per day, so the Pureganic powder is a nice alternative for those who have trouble setting aside that kind of time.

Pureganic suggests you use the powder three times per week to start and then once per week as needed after that. If you'd like to whiten your teeth by several shades and you intend to whiten your teeth regularly, you may be better off going with a more traditional teeth whitening product that you can use several days in a row.

Price

The Pureganic teeth whitening powder is one of the most affordable teeth whitening products on the market and should fit comfortably into just about everyone's budget. The manufacturer doesn't list the size of the container, so it's difficult to compare it with others based on price per ounce, but it's likely that this powder will last you quite a bit longer than most traditional gel- or strip-based products, which typically only include enough product for a week or two of treatments.
