Your A to Z guide to vitamins and minerals for great oral health 

What’s the first thing you think about when it comes to maintaining a healthy mouth? Brushing your teeth twice a day? Maybe it’s flossing daily. Or seeing your dentist regularly.

Of course, those are all vital to good oral health. But have you considered how important your diet and nutrition are to a healthy smile? Here are key vitamins and minerals that can have an influence on your oral health. 

What you don’t eat also makes a big difference to your dental health. Try to avoid sugary, starchy and acidic foods and drinks that can lead to tooth decay. Watch out for food and drinks that seem healthy but are full of sugar or carbs, including pretzels, dried fruit, crackers, granola bars, fruit juices and sports drinks.
