EMMAUS- When you look in your mouth you may see teeth that need whitening, but a dentist may see signs of heart disease. A study published in theJournal of Dental Research found that many dental problems can be signs of serious health complications. University of Washington School of Dentistry professor Philippe P. Hujoel, DDS, PhD, says the sugar and carbohydrates in food, known as “fermentable carbohydrates,” are to blame. Found in sugary drinks, snack foods like potato chips, and simple grains like white bread and corn, these carbs are fermented by bacteria in your mouth, which produces the acids that cause tooth decay. “Those dental diseases are a marker for an unhealthy diet, and an unhealthy diet may predict future health complications,” Dr. Hujoel notes.
