Consider using a straw so the liquid bypasses your front teeth.
Brush or rinse immediately after consuming stain-causing beverages or foods. I use 'extra white sugarfree gum' after porridge and a cup of tea in the morning.

And now to the good part—home remedies:
Mix a quarter teaspoon of baking soda with a little toothpaste. Brush your teeth with this gritty mixture and rinse with warm water. Use it once or twice a week.
Rub orange peel over your teeth every night before going to sleep. The vitamin C and calcium in the orange peel will combat the microorganisms throughout the night.
Grind a few strawberries into a paste. Rub the paste on your teeth gently. If done twice daily for a few weeks, the yellow tinge on your teeth will vanish. Another option is to mix the pulp of one strawberry with one-half teaspoon of baking soda and spread the mixture onto your teeth. let it sit for a few minutes. Rinse out your mouth and brush your teeth with toothpaste to get rid of any residue.
Mix together a few drops of lemon juice and some salt. Apply the mixture on the stained teeth and rub the paste vigorously over your teeth and gums. Leave it on for a few minutes and then rinse your mouth thoroughly with water. Do this twice daily for about two weeks to get rid of tartar and the yellow tinge.
You can use common salt regularly each morning as a tooth powder instead of toothpaste. Take care not to damage your teeth. You can also mix common salt with baking soda and gently rub it on your teeth.
There are a few good suggestions to consider with this lot. I like the idea of orange peel and will definitely give that a try. In the meantime, I'm off to rub the stained snaggly teeth, hiding behind others, with a finger dipped in salt. How about you? Would you consider using any of these home remedies?
