"I’m a dentist. Here’s the lowdown on toothpaste.
As long as it has fluoride they are all basically the same.
When I was in dental school, the [Tooth paste brand] lady came by and said that everything that says [Toothpaste brand] on it is all exactly the same, the only difference is the packaging. So whether it says whitening, or gum protection, or whatever else, it is all exactly the same.
The exception is sensitivity toothpaste typically does have an extra active ingredient. KNO3, which helps with sensitivity.
Don’t ever feel obligated to buy the expensive toothpaste because you think it will be better for your teeth, just buy whatever you like best."
should we construe your statement as confession of your incompetence in the subject?
