Alkaline works for me. I brush with a salt/baking soda tooth powder and use an alkaline mouthwash (Glyco-Thymoline or Alka-Thyme).

Back when Viadent was on the market with blood root it had a high PH.

My dentist recently told me that when I came to see him 40 years ago, he thought I was going to lose my teeth. I've kept my teeth 30 years longer than all the people in my father's family.
