Erodes tooth enamel

Although diet soda doesn't have as much sugar as regular soda, it is still quite acidic and might harm your smile if you drink a lot of it frequently.

Regular and diet Coke had a substantial impact on the tooth enamel's surface roughness, according to a test-tube study, which suggests that both can cause tooth erosion. Another study found that both regular and diet soft drinks' acidity might harm the enamel's surface, causing erosion. But keep in mind that tooth enamel damage caused by acidity is not the same as a higher risk of cavities caused by sugar content. According to one research, children's dental cavities are not caused by diet Coke. Additionally, a study conducted on adolescents revealed that regular intake of carbonated soft drinks was linked to bad eating patterns and worse dental health. However, this might be due to the association between soft drink intake and other bad eating habits and poor dental health in general.
