Sip water between cups of coffee
A swig of water can wash away staining liquids quickly before they start to set into your teeth. Even though science shows coffee isn’t dehydrating, this is still a great way to stay hydrated throughout the day.
Drink it quickly
Let’s say you and your coworker both grab cups of coffee when you get into the office. You drink your whole cup in five minutes, but your coworker takes his time and finishes the same amount of coffee in two hours. Lucky for you, Estafan says that your teeth will be the less-stained ones. Since your coworker exposed his teeth to the coffee for a longer period of time, his will be more stained. Wash even more particles away by following that quick cup with a glass of water. Just don’t burn yourself.
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.
