Natural And Harmless Ways To Whiten Your Teeth
I saw these tips from Dr. Wright and thought I'd share. Foods have natural chemicals in them that can actively affect stains and your teeth. I know people who suck on lemons or pickles frequently and for long periods of time. The results is I've seen their enamel dissolve away, never to return. Don't think that because it's natural, it's harmless.
All acids will dissolve enamel when the pH goes below 5.5, but our teeth are made to handle short-term exposure to acids, followed by long periods of natural remineralization from the rebuilding minerals in your saliva. Otherwise we wouldn't be able to enjoy all the wonderful foods with low pH.
So with the ideas mentioned here, we're dealing with acids so it's important to use these techniques for just long enough to brush them into the teeth, and then rinse them off to raise the pH back up above 5.5 to normal mouth levels. Your teeth were made to handle short-term acid application so whiten away, the natural way.
