First let me state that in my practice, often I give exams on patients of record for an entire month without finding a single cavity. My patients simply do not get cavities. It is not by accident. My team and I spend an enormous amount of time teaching prevention because we believe that nature is the best dentist. What I tell them is this: 1. Use an electric toothbrush two minutes daily, 2. Floss at least every other day, 3. Avoid carbohydrates between meals including fruits, grains, dairy and starches, 4. Have your teeth cleaned and examined twice yearly. Typically I only mention mouthwashes in unusual situations. For example patients who have had dental implants should rinse with an antibiotic mouthwash daily. This would be either chlorhexidine or Tooth and Gum Tonic. For patients with uncontrolled tooth decay such as those with diabetes or prediabetes I recommend a mouthrinse with fluoride such as Fluorigard, ACT or Listerine purple. For all others who want to use mouthwashes I suggest after you have done the above prevention routine, rinse once or twice daily or as needed for fresher breath.
