Dentists often warn against red wine and dark berries as they tend to stain the teeth. Strawberries are an exception to the rule. These bright red fruits contain malic acid, an enzyme that can naturally whiten your teeth. Dr. Irwin Smigel, president of the American Society for Dental Aesthetics, explains that this acid possesses astringent properties which remove discoloration on the surface of teeth. Strawberries are also rich in vitamin C which whitens teeth by removing plaque. Strawberries can remove stains caused by acidic, dark-colored beverages such as coffee, soda, and red wine.
Still, experts say you should be careful with these natural teeth whiteners. Dr. Adina Carrel, a dentist from New York, recommends using them only once a week because their acidity damages tooth enamel with frequent use. Not to mention, these fruits contain plenty of natural sugars. All of which spell bad news for your dental health by making you prone to tooth decay.
How to whiten your teeth: Crush 1 ripe strawberry into a pulp and add some baking soda. Blend until you get a paste. Spread the paste evenly throughout your teeth with a soft toothbrush and leave it on for 5 minutes. Brush your teeth afterwards with toothpaste and rinse with water, or gargle with a mixture of warm water and baking soda. Use dental floss to get rid of any strawberry seeds stuck in between your teeth. Repeat once a week.
