Sugar and carbohydrates are not the only things we ingest that have the potential to damage teeth. Many of us also eat foods and drink beverages that contain acids that contribute to “dental erosion.” This underappreciated problem, which affects as many as 20% of the population, begins with softening (demineralization) of the enamel and underlying dentin, which results in diminished tooth structure. Dental erosion can also result from brushing too forcefully, tooth-grinding, and medications taken by older patients that reduce saliva flow. To prevent dental erosion from occurring, patients are urged to consume fewer acidic beverages, limit consumption of citrus fruits, and use toothbrushes with soft bristles. They should also try to at least rinse teeth after eating.
P.S. By chewing sugarless gum, you can increase the flow of saliva, which helps to mineralize teeth.
