The Best Whitening Toothpastes - and the Worst
Which whitening toothpastes are the best to use?
The best whitening toothpastes for home use must be both safe for prolonged use and safe for the environment.
Here's a look at what's available, what's good... and what's probably best avoided! Which are the very best whitening toothpastes is a personal choice. I hope this page can help make it an informed choice!
Whitening toothpastes can be just simple toothpastes with mildly abrasive ingredients which gently clean the teeth from stains accumulated from foods and drink. There are also plenty of more "advanced formulas" which offer to actually whiten the enamel of your teeth. Some of these wonders are not really that safe and they may also include some ingredients which impact upon the wider environment.
