Preventing Yellow Teeth
If you want to keep your teeth nice and white, avoid smoking and cut back on coffee and soft drinks. Get into the habit of using a straw when drinking dark-coloured and acidic beverages to further help prevent yellow teeth. Drink milk or tap water after eating or drinking something acidic to help reduce the acid's eroding effect.
Brushing and flossing also help, as well as avoiding snacks between meals to allow your saliva to dilute the acids in your mouth. Make sure to use dental products with fluoride to protect your teeth, and get any dry mouth symptoms treated with the help of your dentist.
When brushing twice a day and flossing doesn't help improve the appearance of your yellow teeth, it might be time to consider these whitening options. With so many ways to treat yellow teeth, there's no reason to hide a beautiful smile.
