Onions
You may not love post raw onion breath but the sulfur compounds within it make them powerful in terms of dental health. Bacteria present in the mouth that can cause tooth decay and periodontal disease can be eradicated simply by chewing on some raw onions. It may be unrealistic for you to take an onion and tuck into it right away, but it can be liberal with slices of raw onion on your salads and sandwiches.
