Consumption of starchy foods in combination with sugar has also been found to increase the risk of tooth decay. Regular consumption of small amounts of sugar has been found to be more damaging to teeth than an occasional sugar-rich frenzy. Although dairy products can be beneficial because they are a natural source of calcium, the lactose in dairy products is a type of sugar that can be harmful to teeth. Sugar interacts with bacteria by breaking down the enamel, which can weaken teeth and cause cavities. The balance between starchy foods and the absence of added sugars can make a significant contribution to healthier teeth. Reducing the amount of milk in your diet or switching to lactose-free milk can help reduce the demineralization of your teeth. We all grew up with our parents who told us that if we wanted healthy teeth, we had to drink a lot of milk and avoid consuming too much sugar. Tooth demineralization occurs when minerals such as calcium are removed from the hard tissues of teeth. While it is important to consult an emergency dentist if necessary, it is also important to maintain a healthy diet to prevent tooth decay. Eating the right foods can go a long way toward keeping teeth strong and healthy. In addition, people who are sensitive to lactose may have difficulty absorbing the minerals and vitamins they need for their teeth if they consume a lot of dairy products. Simple carbohydrates increase fermentable sugars in the mouth, which can lead to tooth erosion. Acidic foods can be extremely harmful to dental health. Some foods can delay remineralization of teeth. Surprisingly, there are other foods that have a low pH, including coffee, wine, tomato products, and cucumbers. Fruit juices and citrus fruits such as oranges, blueberries, lemons and apples are acidic and can cause dental erosion.
