In a health-conscious world, the word “soy” receives mixed reviews. Some praise soy for its health benefits as an alternative to such foods as milk and meat, while some consider it useless, if not downright harmful, to our physical wellbeing. A new study from University of Melbourne’s Dental School in Australia suggests that soy milk may actually be more harmful to your teeth compared to cow’s milk. Your Corona dentists explore the study and what it may mean for soy milk consumers.
Production of Acid
Bacteria constantly form in your mouth and accumulate into a biofilm known as plaque, which coats your entire mouth. The bacteria is a mix of helpful and harmful microbes, and in a healthy mouth, the bacterial population can be controlled by natural defenses like saliva and tooth enamel. When you eat or drink, the bacteria metabolize sugars and carbs and excrete lactic acid on the surface of your teeth. Acids weaken your enamel, and sap minerals from your tooth so the enamel cannot regain its strength. When the enamel is sufficiently weakened, bacteria have access to the interior of your tooth, where they can cause decay and severe sensitivity. Cow’s milk contains high volumes of calcium and phosphate, the same minerals your enamel is made of, and that acids siphon from your tooth. By drinking milk, you can assist your enamel in remineralization by providing a source of calcium and phosphate. Cow’s milk also has the added benefit of neutralizing acids, lessening their attack on your teeth. (more…)
