Minimize exposure to TV and CRT screens. Use vegetable-based soap. Clean fruits and vegetables well before peeling or eating. Store cooked food in airtight containers. Use an oral irrigator after every meal.
Oral irrigation is more effective and gentler than flossing.
Brush your teeth twice a day with an electric toothbrush. Use a non-fluoride natural toothpaste. Speak to your dentist about using composite fillings and porcelain crowns and bridges. See a periodontist for scaling and root-planing, but try to avoid periodontal surgery. Rinse your nose with lukewarm slightly-salty water every day.
