i have not tried the hydrogen peroxide. are you suggesting the 3% or the 35% strength peroxide? i think the latter - one needs a prescription.
i did try using a clay as a tooth cleanse. it did something. but not enough. i just have to try some of your suggestions. this thursday i will have my teeth cleaned by my periodontist. it should be an interesting adventure. i have been doing oil pulling for the past 6 weeks. my gums feel really good.
and please let me know about the peroxide question.
