Swish apple cider vinegar
This tip is admittedly controversial. The acid in apple cider vinegar can whiten teeth and remove stains, but it can also cause erosion. It’s especially hard for dentists like Estafan to gauge its risks and benefits without knowing the acid concentration, how long a person swishes it, and how often he or she swishes. Use caution until researchers make definite conclusions about this method. And consider these other uses for apple cider vinegar.
Chew sugar-free gum
Conquer coffee breath and clean your teeth at the same time. Chewing gum increases the amount of saliva in your mouth, and saliva washes away acids and plaque from your teeth. According to the American Dental Association, chewing sugarless gum for 20 minutes after eating can help prevent tooth decay.
