Whitening Toothpaste?
Does this have a detrimental affect to the teeth in chemical form? Just wondered how it worked and if all is good with it.
Answers
It works partly by physical means (extra coarse abrasive to scour stains away) and partly by chemical means (very weak peroxide bleach- so weak that it can't have much effect). The worst you can do is use it too often and very vigorously- you'll wear the enamel away quicker!
