Rub on some fruits:
Grab a few of your favorite red fruits (strawberries and tomatoes to be exact) and rub them on your teeth. Let the juice stand on your teeth for five minutes to soften the buildup. Rinse your mouth with baking soda and warm water for a brighter smile. Other foods that work well include bell peppers, berries, lemons and oranges, according to Positive Med.
In addition to these simple recipes, a few changes in your routine may help too. Ditching the tobacco, brushing and flossing regularly, and upping the spicy foods in your diet (to promote saliva build up and the natural cleaning process) will drastically change your oral health in the right direction.
