Does Apple Cider Vinegar Damage Your Teeth? How to Protect Your Enamel

Yes, apple cider vinegar can damage tooth enamel if you drink it undiluted or often, because it is acidic. You can lower the risk by diluting it well, drinking it in one go, rinsing your mouth with water afterwards, and waiting about 30 minutes before brushing.
Why vinegar affects teeth
Enamel is the hard outer layer of a tooth. Acidic foods and drinks, including vinegar, citrus juice and fizzy drinks, can soften it for a short while. Repeated exposure over time can wear it down. This is why dentists suggest keeping acidic drinks to mealtimes and not sipping them all day.
How to protect your teeth
- Always dilute. Use 15 ml (one tablespoon) in a full 250 ml glass of water, never undiluted.
- Drink it in one go rather than sipping for an hour.
- Use a straw if you like, to reduce contact with your teeth.
- Rinse with plain water straight afterwards.
- Wait about 30 minutes before brushing, because brushing softened enamel can wear it.
- Keep it to one serving a day.
What about sensitive teeth?
If you already have sensitive teeth, worn enamel or gum problems, speak to your dentist before taking vinegar in drinks. You may be better using it only in cooking, where it is mixed into food.
Gentler ways to use vinegar
- Salad dressings and marinades
- Chutneys and quick pickles
- A splash in soups or lentils for brightness
Signs to stop
Stop and speak to a dentist if you notice new sensitivity to hot or cold, a rough or chalky feeling on your teeth, or a change in how your teeth look.
If you use it, Mevva Raw Apple Cider Vinegar with Mother (5% acidity, 250 ml) should always be diluted.
