Hi Dr. Manhart, Success! I brushed two evenings ago with the calcium tooth brush, then in addition I did the chips yesterday evening. This morning, no blood, for the first time in a very long time. I usually bleed more in the evening when I brush, and it’s always so much, like from an open wound, this morning no blood at all! I am amazed! I didn’t experience a blood free morning before the calcium therapy. Thank you for your kind advise and caring guidance. I would love to come and see you one day. ~ Nina in FL
