One of the primary effects of acidic drinks on teeth is enamel erosion. As suggested by the Academy of General Dentistry, tooth enamel, which is the hard outer layer of the teeth, can become soft and thin with prolonged exposure to acidic drinks and some herbal teas. Although saliva helps strengthen the teeth after exposure to small amounts of acid, this action does not occur when there is excessive acid in the mouth. There is an increased possibility that the teeth will chip or crack with enamel erosion.
Additional dental problems, such as discoloration and tooth sensitivity can occur when acidic drinks erode tooth enamel. As the enamel weakens, the second layer and largest part of a tooth, known as the dentin, becomes exposed. When the tiny tubes that comprise dentin lack a protective covering, the teeth appear yellow. In addition to discoloration, the nerves in the exposed dentin tubules are vulnerable to hot and cold drinks, resulting in tooth sensitivity and pain.
Although eating sugary foods and improper oral hygiene are primary causes of cavities, consuming acidic drinks can also result in tooth decay. Cavities, which are tiny openings or holes in the teeth, can develop because of enamel erosion. When there is less enamel, the teeth are more vulnerable; it is easier for bacteria to penetrate and cause decay. Toothaches, tooth sensitivity and visible holes in the teeth or pus around the gums are signs that tooth decay is occurring. If left untreated, cavities can result in infection, intense pain and tooth loss.
There are several ways to protect the teeth from acidic drinks. First, limit your daily intake of carbonated drinks and use a straw. The straw helps the teeth avoid contact with the acid by directing the fluid to the back of the mouth. Prolonged exposure to acid increases the rate of enamel erosion. As such, consume acidic drinks quickly and do not swish them around in the mouth. Good oral hygiene such as brushing twice a day and regularly seeing the dentist also help protect the teeth.
