I have had a very bad abscessed tooth, so I have been trying all kinds of things on here because I cannot afford a dentist.
I took coffe filters, cut them up into small pieces, filled them with charcoal from charcoal pills, wetted them lightly, then pressed them around my problem areas, they did great for maybe 15 mins. , tried this twice with the same results. Also, my pain was extreme after they stopped working.
