When we mention how to spice up your sex life or how to slim down, most people are all ears. But when we talk about your gums, you tune out like teenagers at the dinner table.

Well, here's why that body part is even more important than what everyone wore to the Oscars: In severe gum disease, the tissue involved is approximately the same size as the skin on the back of your hand. What would you do if the back of your hand were red and swollen, and bled at the slightest touch? You'd haul your buns to the doctor.

One way to keep yourself from getting anywhere near that stage of periodontal disease is by adding green tea to your daily menu (you're already brushing and flossing regularly, right?). In one study, the more green tea men drank, the better their gums fared during dental exams.

Catechins, natural compounds in green tea, may help prevent cavity-producing plaque from forming and protect teeth and gums from disease. Catechins also may help reduce gum inflammation (the nasty end result of that plaque).

Other reasons green tea gives you a great smile: It kicks enamel-busting beverages -- including sodas, citrus juices and sports drinks -- out of your fridge (and your mouth). Oh, and one more thing about the green stuff: It tastes great. Try it iced as well as hot.
