According to the ADA (American Dental Association) sugar in soft drinks, fruit juices, and sports drinks can lead to tooth decay. Acid is produced each time sugar comes in contact with the bacteria in your mouth. This acid eats away at your teeth for about 20 minutes after yo u take a sip and this acid can result in cavities. Unfortunately, diet soft drinks and carbonated water are not any better.
The ADA says that most soft drinks also contain phosphoric and citric acid, which can cause tooth erosion. To improve your dental health, you should try to limit your soft drink consumption and instead snack on nutritious foods. Other dental health tips include making sure you brush twice a day, floss once a day, and see your dentist regularly for a check-up.
