Enamel erosion is the gradual wearing away of the tooth's protective surface by acid. Unlike decay, it is caused directly by acids, often from diet.
Quick answer
Enamel erosion happens when acids from foods and drinks (citrus, fizzy drinks, wine, vinegar) or from reflux dissolve the enamel over time, making teeth sensitive, yellowish and thin. Enamel does not grow back. Protect it by limiting acidic foods, drinking water, using a straw, not brushing for 30 minutes after acid, and using fluoride toothpaste.
Common causes
- Acidic foods and drinks: citrus, fizzy drinks, wine, vinegar.
- Frequent sipping of acidic or sports drinks.
- Acid reflux or frequent vomiting.
How to protect enamel
- Limit acidic foods and drinks; rinse with water after.
- Use a straw for acidic drinks.
- Wait 30 minutes before brushing after acid.
- Use fluoride toothpaste and see a dentist if you notice sensitivity.
