  1. What is the Connection between Anaerobic Metabolism and Dental Plaque? By, Jill Johnston

  2. Dental Plaque • Bacteria • Polysaccharides form sticky colonies • Plaque formation • Anaerobic metabolism

  3. CAUTION! • High Sugar Diets • Carbohydrates: Sugars, Starches • Examples: Candy, Fruit, Cake, Soft Drinks, Ice Cream

  4. How it works… Carbohydrates (Sugars and Starches) Bacteria present in mouth utilize sugars ex: Sucrose Acids (waste products) ex: Lactate & Pyruvate

  5. Over time… Overtime acid destroys tooth enamel, even dentin rapid bacterial growth in holes made Causes ToothDecay and/or Gingivitis long term Plaque on tooth roots, under gum, can cause breakdown of bone and tooth support (Periodontal Disease)

  6. Bacteria uses fructose to get energy Lactic acid creates extra acidity to decrease the pH, which can dissolve the calcium phosphate in the tooth enamel leading to the start of a cavity.

  7. Over-view Sugar, Saliva, and Bacteria lead to tooth decay over time.

  8. Treatments • Flossing • Brushing • No Tobacco use • Good Diet • Fluoride • Home tests • Yearly exams/cleanings (PIC.) • Holistic treatments

  9. Dangers • Gum Disease (Gingivitis) • Tooth Decay • Severe Gum Disease (Periodontal Disease) • seems to be associated with: • *Heart Disease • *Diabetes • * Dementia • *Heart attacks • *Premature birth • *Rheumatoid • Arthritis
