BETTER BUT WITH SIDE EFFECTS
The other night I swished with drug store hydrogen peroxide to see if it would indeed remove the tea and coffee stains from my teeth. The peroxide was 3% (the kind that says it's for oral use) mixed with an equal amount of water. The directions say to swish it for at least a minute, I did it for ten minutes. There was no apparent difference immediately afterward. The next day (or was it the day after that?) I made a recipe with turmeric in it and immediately after eating it brushed my teeth with baking soda. I was surprised because then the teeth suddenly seemed whiter. But now my gums are very sensitive to my toothbrush and bleed a bit. I have been using a hard bristle brush with baking soda once a day at night, and never had a problem like this before. They were not sensitive prior to this incident. Just a word of caution.
