Although healthy, fruit juices such as orange or pineapple also have acidity. Its erosive effect on the enamel is similar to that of solid citrus fruits.
3. Carbonated drinks, even sugar-free
Both common and “light” sodas contain phosphoric or citric acid, which demineralizes the teeth.
Datum: Even a single can can alter the pH of your mouth for more than 20 minutes.
4. White and red wine
Both types of wine contain natural acids that affect the enamel. In addition, red wine stains teeth, and immediate brushing can further fix those stains.
5. Vinegar and pickles
Foods with vinegar, such as pickles or salad dressings, also temporarily modify the surface of the tooth.
Why is enamel so vulnerable?
When we ingest acidic foods or drinks, the pH of the mouth drops. This causes a softening of the tooth enamel, which can last between 20 and 40 minutes. If we use a toothbrush during this period, we will be rubbing a weakened surface, generating micro-wear. In the long term, this causes sensitivity, increased risk of cavities, and visible wear and tear on the teeth.
