If your teeth are having problems, the rest of your body has problems with needing to detox or just needing better nutrition with enough minerals to make your teeth healthy. The Natural Healing Paradigm is what detox on this forum is about. The feeding end of it is something you will have to figure out for yourself. Strive for simplicity and balance. Just as necessary as detox is feeding your body the nutrients it needs to stay healthy. You may be able to get your body cleaned up in a year. For some of us, it has taken a lot longer, but it's worth it. The quality of food is important if you are to stay healthy. We can't compromise by eating out of places like McDonalds and other places like that and stay healthy. If you possibly can, grow your own food.

The problem everywhere is broad spectrum. Go back to a healthy lifestyle. That will keep the health problems in general down.

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.
