I have noticed that many dental patients believe that it is okay to drink soda and sugary drinks – if these are marketed as “diet” drinks. Although diet drinks may not have the sugar content which can cause decay, the acidic content will cause significant erosion on the teeth which will eventually be attacked by bacteria and turn into cavities. A research project done at the University of Michigan showed that there is no difference in the amount of erosion between diet and non-diet soda and both cause the same type of erosion of the teeth.
You can also refer to the mouth healthy website to learn more about sugary drinks. Most drinks, even those that claim to be healthy, contain sugar.
Dentist’s advice: Make sure you limit the amount of sugary drinks per day and always brush your teeth two to three times a day and drink water after eating or drinking sugary food or drink.
