Bad news: Americans aren’t exactly diligent with brushing their teeth. While most people know that brushing their teeth twice a day is necessary, an informal survey conducted on Reddit (and published on Yahoo.com) found that only 44% of men and 37% of women follow this rule of thumb.
Perhaps it isn’t surprising, then, why 70% of the population is missing at least one tooth. While your pearly whites are one of the toughest parts of your body, they aren’t impervious to damage. Neglect them long enough, and before long they’ll develop cavities that might cause toothache–and eventually, tooth loss.
