The tooth and Gum Spray has the best side effects of the sprays if your a man, if your a woman, the other sprays have the side effects of lessened period pains.....ormaybe the tooth and gum has this also, but we need a woman to use ONLY the tooth and gum for a few months and nothing else to know that. The tooth and gum seems to have the side effects of better coordination of the hands.
As far as liquid tooth and gum goes, the spray is liquid and I also make a "squirt" bottle of it that has a little maple syrup in it for Trevor, so the squirt formula is like cany to him, in that he loves the taste.
