Dental erosion is the irreversible loss of tooth structure due to acids from foods and beverages. Signs may include tooth sensitivity, transparency of the biting edge of teeth, and discoloration near the gumline of the teeth.
On a pH scale of 1-14, water is neutral at 7. A lower number indicates more acidity. Carbonated beverages and sports drinks can have a pH around 2.5 and any beverage with a pH lower then 5.5 can cause dental erosion.
Extreme cases may require fillings or crown restorations to treat. Prevention is better though. Minimizing exposure to acidic beverages and/or drinking them through a straw will help. Minimizing abrasive forces is good too. A soft bristled toothbrush will not erode dental enamal.
Ask your dentist or hygienist about specific question dental issues.
