What comes out of the gums is toxic stuff already present in the body that you need to clean out. What dentist knows what we do here on this forum? I might say ZERO, so get your body cleaned out. kill the bugs, clean out the colon and liver that will let the blood and lymph clean out. The last of the detox is the tissues, but by the time you get there your body may have already done a lot of tissue cleaning. Anything on-the-spot when you are having problems BEFORE cleaning out your body that will help seems to me to be like a good thing to do. I only agree with the re-mineralization of the tooth. Barefoot has tooth and gum formula. http://www.oldfashionedspices.com
I have no knowledge of the other 2 things you mention. Any foreign object that enters the body becomes a place for biofilms of bugs to form, so I'd say "no, I wouldn't do them".
Bug biofilms have infection in them, then the object has to be removed and the area cleaned up. Don't waste your money.
