Enamel hypoplasia is a condition that affects the development of tooth enamel in both primary and permanent teeth. Enamel HypoplasiaĪlthough enamel hypoplasia is not as common as the other two causes, it can also lead to translucent teeth. Celiac’s disease is another medical condition that can contribute to translucent teeth because it affects the development of tooth enamel. Since stomach acid has a low pH, it is highly corrosive and erodes the surface of your teeth. These conditions include heartburn, acid reflux, bulimia, morning sickness, or any other condition that causes frequent vomiting. There are also certain medical conditions that cause the teeth to be exposed to more acid than usual. While some demineralization is normal, too much demineralization can quickly lead to tooth decay and enamel erosion. In fact, tooth enamel begins to demineralize around a pH of 5.5 or lower. Generally speaking, the more acidic foods and beverages you consume, the faster your enamel will erode since these foods and beverages lower the pH concentration in your mouth, making it more acidic. Foods that are highly acidic, such as citrus fruits, as well as beverages that are highly acidic, such as sodas, can cause the enamel to erode over time.
