Excessive use of food with low pH value can cause dental and oral health issues. Low pH foods include, but not limited to, alcohol, cola and soft drinks, fruit juices, fresh fruit, tea, coffee, pickle and yogurt. One of the damages of such food is dental erosion. Dental erosion is the breakdown of tooth structure caused by the effect of acid on the teeth. Dental enamel is the thin, outer layer of hard tissue. This tissue helps in maintaining structure of tooth and shape. It also protects it from decay.
