Question:
How do they test the long term safety risks of dental products?
Like teeth whitening, or fluoride? How do they know it's not going to make your teeth fall out in a few years?
Answers:
They have a group of people who are willing to try it for a certain amount of time, and these people are paid. However, much of what their research is based on is products that already exist, or the ingredients within. If you read the labels, you'll find that most "new" products along these lines are made of the same things that were already available in another form, only they label it differently.
