I have been doing this for awhile. I use organic coconut oil. And I do it once or twice per week. I'm obsessed with teeth and the whiteness of mine but I do not use commercial whitening on them. I get a lot of comments on how white my teeth are and recently my extended family had pictures made and the photographer asked if she could shade my teeth because compared to the others in the picture my teeth were cosmic white lol. I brush my teeth with Colgate and I floss and use Listerine blue. I mostly drink water and soon from a straw anything that might damage my white teeth. I don't know if it will hwlpbyou but I also know I've had no dental concerns.

I the second was toss I swallow little worst thing I throw all of it up its hard but I'll get us to it I last it longer first day was five mins today almost nine mins I am doing it because my gums bleed. i am with you I drunk only water as well

I've heard about coconut oil and bakingsoda. Yet to try
