Frequently consuming foods with a low ph value, such as soft drinks, fruit, juices, pickles, and yogurt can lead to irreversable 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 that helps maintain the tooth's structure and shape while protecting it from decay.
Ph (potential of hydrogen) is a standard way to measure the acidity of a substance. It is measured on a scale of 1-14. A lower ph means that a solution contains more acid. The higher the ph, the more alkaline (or non-acidic) the solution. When a solution is neither acid or alkaline, it has a ph of 7, which is neutral.
When acidic foods or drink are consumed, the enamel will soften for a short amount of time. Typically, saliva slowly helps to restore the natural balance of the acid in the mouth. If foods high in acid are consumed on an excessive basis, the mouth can't repair itself and there is a greater chance f
