When "Happy Days'" Ralph Malph - aka Mouth - bragged that his teeth were so straight folks thought he was a movie star, he ID'd one of the perks of a great smile. But there are even more benefits!

A healthy mouth means you're helping make sure you avoid cognitive problems, diabetes and heart disease, as well as tooth decay.

You know you should brush twice a day, floss once a day and see your dental health professional every six months. But here are more ways to stay healthy and keep that beautiful smile!

1. Eat a tooth-friendly diet: Canned salmon, almonds and dark leafy greens are loaded with tooth-building calcium.

2. Take 1,000 IU of vitamin D-3 a day (D helps build strong teeth), until you get your blood level measured; then take the amount that's right for you.

3. Drink tea. It's got natural fluoride to help prevent cavities.

4. Avoid foods and drinks with added sugars or sugar syrups - not only does sugar decay teeth, it contributes to obesity, which is associated with dental problems.
