In fact, enamel is the hardest substance in the human body. But despite its strength, it has one big weakness - once it's worn away, your body can't grow it back. That's why looking after your tooth enamel is one of the best things you can do for your smile.
Foods and drinks that can wear down enamel
The good news is that you don't have to avoid your favourite foods altogether. It's more about how often your teeth are exposed to acids and sugars than eating or drinking them occasionally.
Citrus fruits
Oranges, lemons, grapefruit and pineapple are packed with vitamins, so there's no need to cross them off your shopping list. However, they're naturally acidic, so frequent exposure can soften tooth enamel. Drinking water afterwards helps rinse away acids and gives your mouth a helping hand.
Soft drinks
Whether they're regular or sugar-free, soft drinks are highly acidic. While sugar-free versions don't feed the bacteria that cause tooth decay, they can still contribute to enamel erosion because of their acidity. Water remains the best choice for keeping both your body and your teeth happy.
Sports and energy drinks
These drinks are often surprisingly acidic and can wear away enamel, particularly if they're sipped over long periods.
Fruit juice
Even 100% fruit juice contains natural acids. Enjoy it in moderation rather than sipping it throughout the day, as repeated acid exposure increases the risk of enamel erosion.
Lollies
Hard, chewy and sour lollies can all be bad news for your teeth. Sugary lollies feed the bacteria in dental plaque, which produce acids that attack tooth enamel. Sour lollies are even tougher on teeth because they combine sugar with high levels of acid.
Signs your enamel may be wearing away
Enamel erosion usually happens gradually, so the early signs can be easy to miss. Watch out for:
- Increased sensitivity to hot, cold, sweet or acidic foods and drinks.
- Teeth that appear more yellow as the enamel thins and the layer underneath becomes more visible.
- Edges of the teeth that become rough, chipped or more jagged.
- Teeth that look smoother or shinier than usual.
If you notice any of these changes, it's a good idea to book a dental check-up.
How to protect your enamel
Looking after your enamel doesn't have to be complicated. A few simple habits can make a big difference.
- Drink plenty of water throughout the day.
- Keep soft drinks, sports drinks and fruit juice to occasional treats rather than everyday drinks.
- Avoid sipping acidic drinks over long periods.
- Rinse your mouth with water after acidic foods or drinks.
- Wait at least 30 minutes before brushing after consuming acidic foods or drinks, as enamel is temporarily softened by acid.
- Brush twice a day with fluoride toothpaste and have regular dental check-ups.
Your enamel works hard every day to protect your teeth. With a few tooth-friendly habits, you can help keep it strong for many years to come.
