6. Make a Homemade Tooth Whitening Paste
Coffee drinkers can whiten their teeth at home with an easy homemade paste made of two common household ingredients — hydrogen peroxide and baking soda. Be careful, though, as a mixture with too much baking soda might damage tooth enamel.
For easy home tooth whitening, mix three or four drops of hydrogen peroxide with a little bit of baking soda. If the mixture is gritty, add more liquid or start over. An overly gritty paste could permanently scratch the enamel of your teeth.
Add the homemade paste to your toothbrush and brush as you would with toothpaste. Rinse and spit out the DIY whitening paste without swallowing it.
5. Drink Through a Straw
The less coffee that coats your teeth, the fewer stains will be left behind. Using a straw when you drink coffee is an easy hack for keeping your teeth whiter. We don’t just mean with iced coffee, either.
Yes, even hot coffee can be drunk easily through a straw. If you’re a die-hard coffee lover, consider investing in reusable metal straws. They’re affordable and stand up to the hottest cup of coffee. They’re also handy to have for drinking coffee from tall travel mugs.
4. Drink Coffee with Milk
The casein in milk could lessen the stain power of your cup of coffee. A 2014 study in the International Journal of Dental Hygiene showed that tea mixed with milk “significantly reduces the ability of tea to stain teeth.”
Mammal milk naturally has casein. Adding dairy-free, plant or nut milks might not have the same effect for preventing coffee stains.Related: 10 Home Remedies for a Tooth Abscess
