International Health and Health Network reported recently that Professor Baez of the Department of Orthopaedics and Rehabilitation Medicine at Temple University in the United States found that using drinking straws to drink soda can reduce the risk of tooth decay and protect dental health, but the straw must be placed correctly local. The carbonated drinks that youngsters like very much because they contain a lot of acidic substances, often drink easily lead to tooth decay.

Even canned iced tea contains organic acids such as malic acid, which are quite corrosive to teeth. Prof. Baz’s statistical analysis of those who have a drink habit found that the frequency of drinking and the amount of beverages that remain in the mouth each time can influence the type, location, and severity of tooth decay.

Professor Baez pointed out that drinking carbonated drinks directly from the mouth would make the mouth look like a pool filled with carbonated drinks. The teeth are completely “soaked” with acidic substances, which can easily lead to tooth decay; placing the straw on the front of the incisor tends to cause tooth decay near the front teeth. Placement of the straw behind the incisors, pointing to the esophagus of the drink, minimizes the contact of acid with the teeth. But even if you drink it with a straw, your teeth will still come in contact with the sugar acid liquid. Therefore, it is best to gargle with water after drinking, and brush your teeth with fluoride toothpaste.
