I need to correct what i said about h202 that you buy in the store, as I'm sure everyone caught it. H202 is diluted to 3% @ drug stores etc.,not 35%.I am still looking for a website connected to this product to give more accurate info , Sorry ,I should have been more prepared to give info. However I do have the website for the GSE. It is nutribiotics.com this is such a good antibacterial agent Iuse it alot, as I said before. One more goody ,when you combine 1/pt baking soda w/1pt celtic seasalt & add a little of your favorite oil eg,/ peppermint or clove etc. It makes a fantastic tooth whitener. Not to mention freshener and disinfects as well. Some people I know use it everyday without any abrasion problems, But use to your own discretion.Then rinse with peroxide and it can be a very effective cavity prventative. My dentist says cavities are caused alot from bacteria as well as other things. Thanks for all the great posts everyone!
