I am on vacation and I suddenly got terrible pain in my tooth. The pain didnt go away and kept getting worse. I was maxed out on Advil and couldnt find a Dentist. So I put the M1 on my face with two coils and wore it all day long. By Day 3 the pain was nearly gone. I could tap the tooth and stopped taking Advil. I notice I still feel something, but when I wear the M1 for awhile the low level pain goes away. I cant wait to see what my Dentist says this week… The M1 saved my vacation and maybe my tooth.
