I do this twice a day:
mix Hydrogen Perioxide with water (50/50 of each), swish around in mouth for 2 mins (or until it gets too foamy to swish..)
then i brush my teeth with CREST Dual Action Whitneing toothpaste for 3 mins. then rinse.
been doing this since i was 14-never ONCE had a cavity or any other problems!!!!!!!
