Your teeth are at risk every time you eat or drink something acidic such as orange juice or fizzy drinks. There are many factors which influence how your teeth erode such as:
• The pH level or acidity of the food or drinks that you consume
• The total level of acid in the food or drink
• The type of acid that you consume- food and drinks contain many different types of acids
• The structure of your teeth and the saliva in your mouth can even have an effect on how your teeth erode
