Has anybody used baking soda to make a paste to whiten your teeth?
I've recently discovered the taste for coffee and in return had my teeth stained.
I want to try some sort of cost effective and safe teeth whitening, I thought about the whitening strips but thought baking soda would be more safe as a first timer.
I've read that it can make your teeth sensitive but mine are anyway and I use sensadyne, some say use every other day and some say once a week.
Do you brush every part of you teeth or just the visible areas?
Has anybody tried this?
