Food can be categorized as “smile-challenging” or “smile-friendly” explains Jonathan Levine, DMD, spokesperson for ProNamel toothpastes. Smile-challenging foods are acidic and lower the pH level in your mouth, threatening your teeth with too much acidity; whereas smile-friendly are alkaline foods that raise the pH level in your mouth to a healthier level for your teeth. (These are the best hygiene tips for healthy, white teeth.) Apples are a great alkaline fruit, says Dr. Levine. Not only do they raise your mouth’s pH, but apples also act as “a natural exfoliate to take stains off the teeth,” says Dr. Levine. (Brushing with a toothpaste like ProNamel Strong & Bright can help build a protective barrier on teeth to guard against acid erosion.) Read more about the many health benefits of apples.
Herbal tea or unsweetened fruit juice
You may love carbonated sodas, both the diet and regular kind, but they threaten the health of your teeth. Carbonic acid is found in all carbonated beverages, and produces a nasty acidic environment for your teeth, explains Dr. Levine. Instead, opt for herbal tea, non-sweetened fruit juices, or just plain ol’ water. Found out more health benefits of herbal tea.
