There are two related reasons why your teeth slowly turn from white to yellow. The first well known one is foods and drinks that stain them directly and the 8 worst offenders for doing this will be covered ahead.
1. Black Tea
2. Cola, Soda and ‘Sports’ Drinks
3. Sugary Sweets
4. Red and White Wine

2 Simple Ways to Prevent Yellow Teeth
You might be tempted, after reading about how staining and acidic to your teeth some of your favorite foods and drinks can be, to reach for your toothbrush straight after eating them. That would be a mistake.
Dental enamel actually becomes softer after eating one of these foods or drinking one of these drinks for at least half an hour afterwards. Brushing during this time may actually make things worse by wearing away the weakened enamel. Fortunately it should harden again within the hour so you can brush your teeth with a soft bristled toothbrush then if you like.
A better way is to remember to do 2 simple things after eating or drinking any of the suspects on the list above.
The first is to have a big sip of water after you’ve finished your meal or drink and swirl it around your mouth to clear away any acids or staining compounds. Just remembering this alone can make a big difference to how white your teeth stay.
The second is to actively try and get more saliva into your mouth after eating and let it move over your teeth. It’s easy to do after a sip of water and saliva is your mouth’s natural defense against enamel erosion, staining and cavities.
You’ve probably heard of chewing sugar-free gum after a meal for the same reason, but it isn’t needed (most sugar-free gum contains potentially dangerous aspartame so it’s best avoided). As long as you swirled water around first, you should be easily able to build up a little extra saliva and do the same again with it.
Before long this will become a habit that will keep your teeth strong, white and protected, even if you eat and drink some of the things on the list fairly often.
