Teeth stains

What causes them: Beverages such as red wine, coffee, and dark soda can do a number on your pearly whites. 

What to do: Crush a strawberry to a pulp and mix it with baking soda until blended. Use a soft toothbrush to spread the mixture onto your teeth, and leave on for five minutes before brushing it off. (Just be sure not to do this more than once a week, as too much acid from the fruit can damage your teeth's enamel.)
