So far I am pleased. I have been using this product for two weeks now along with the mouthwash. I have terrible teeth. I have a lot of previous dental work….many crown and fillings, root canals etc. My teeth are sensitive to cold. My gums have really receded in the past few years due to multiple pregnancies and nursing babies for years. I also had a tooth crack and a large piece broke off the molar when I bit down on a sucker. I was in Florida when it happened and had no access to my dentist. Anyway, since using the powder and the mouthwash I have noticed the following: teeth feel clean and smooth, breath is better, my gums no longer bleed(that stopped after just one week of use), my teeth are whiter and the best part….the gum area around my crowns is slowly coming back up to the level it should be and not exposing the root of the tooth. I still have some small cavities(little black dots on a couple of teeth)but I firmly believe this will heal them. My back broken molar remains ok for now…it is slightly sensitive but doesnt hurt. I just put the powder down in the cracked part and let it sit. We dont have money for all the expensive dental options for me and I always have to be sedated due ti past dental trauma. I am a lot of work arent I? LOL!! I will report back as time goes on but I am really pleased so far.
