While good oral hygiene can improve your breath, keep your teeth white and make for a pleasant social experience for those around us, brushing and flossing is not necessary for preventing tooth decay. "Some groups of Indigenous people who had fermentable carbohydrates stuck on their teeth all of the time, without any brushing or flossing, were mostly or entirely free of tooth decay."
"You can minimize your tooth decay, prevent it entirely, and even heal tooth decay once a cavity has formed, if you make good choices for yourself based on the knowledge of the lifestyle led by decay-free Indigenous people." |

The fluoride becomes less effective as it does not bind well to tooth enamel, thus it loses its ability to brush away bacteria in the mouth and protect against cavities. Ingredients start to separate, including the flavoring so it becomes quite unpleasant to your taste buds. Toothpaste may just become too dried out and hard to squeeze through the tube. Read more. But don't throw it away; surprisingly, there are a ton of uses for toothpaste outside of the mouth. |
