Like cheese, yoghurt is high in calcium and protein, which makes it a good pick for the strength and health of your teeth. The probiotics, or beneficial bacteria, found in yoghurt also benefit your gums because the good bacteria crowd out bacteria that cause cavities. If you decide to add more yoghurt to your diet, choose a plain variety with no added sugar.
Leafy Greens
Leafy greens typically find their way onto any healthy foods list. They're full of vitamins and minerals while being low in calories. Leafy greens such as kale and spinach also promote oral health. They're high in calcium, which builds the enamel on your teeth. They also contain folic acid, according to the Indian Academy of Sciences. Folic acid is a type of B vitamin that has numerous health benefits, including possibly treating gum disease in pregnant women, according to the International Journal of Health & Allied Sciences. If you have trouble getting leafy greens into your diet, add a handful of baby spinach to your next salad or throw some kale on a pizza. You can also try adding some greens to a smoothie.
