2. Cheese or milk
Acid from the foods we eat can eat away at our teeth. But many dairy products can actually reduce the acid in your mouth. And a glass of milk or a piece of cheese is filling. “It satisfies you as far as hunger goes, and sugar found in milk doesn’t contribute to tooth decay,” says Dr. Ron Smith, president of the Canadian Dental Association and a practicing dentist in Duncan, B.C.
3. Raw onion
Try a slice or two of fresh onion on your sandwich. Research at a Korean University showed that raw onions have powerful antibacterial properties. In an experiment, onions wiped out four strains of bacteria that can cause cavities and gum disease. Of course, after eating raw onions you may end up with killer breath!
Cashew nut shell oil has been shown to have microbe-fighting properties against bacteria that lead to tooth decay. Not only can these nuts help keep your teeth clean, they may also clear your skin – research shows cashew nut shell oil helps to fight one of the bacteria that cause acne.
