Work very good

So, far it has worked for me . I bought it , because  a piece  of chip cut my gum & it got swollen . And it was even causing jaw pain & ear pain. When I got the charcoal  powder it worked very good by the next day the swelling was reduced  by a lot. The only bad thing I used to much powder  it made my teeth black .it takes alot of rinsing & alot of rinsing  of my toothbrush.  Just rinse as much as you can out & rinse off toothbrush, because you will need it to take off what is left on teeth & gum line . I gave up on it ,because of the messiness,  but I shouldn't  have ,because my gum situation  didn't  get better 100%and it is bothering me again. So, I will start back up till it gets all the way better
