Lessen Stains : Cut Back some foods
Its not needed to cut all teeth-staining food and drinks out of your diet. Some of them like blueberries, blackberries, and tomato sauce are rich in antioxidants. So keep eating them, but ease up a bit or try to have cauliflower, apples, grapefruit, and melon.
Use Straw as a tool
Sip stain causing drinks like sodas, juices, and iced tea through a straw. This will help you to keep the liquid away from your teeth.
Swallow food Swiftly
Don’t let stain causing foods and drinks linger in your mouth. Swallow them. When it comes to food, though, chew it well and don’t gulp to make sure you don’t choke.
Rinse & Brush After Eating
Swish your mouth with water right after you eat or drink something that can stain. Wait an hour before you brush. If you can’t get to your toothbrush, chew a piece of sugarless gum as soon as you’ve eaten.
