There are several factors that make the teeth dull and lose their bright white shine. Certain foods can stain your enamel, which is the outer layer of your teeth. In addition, the construction of plaque on the teeth can make them look yellow.
This type of discoloration can usually be treated with regular cleaning and whitening solutions. But sometimes things turn yellow because the hard enamel erodes and reveals the dentin underneath. Dentin is a natural yellow bone tissue underlying the enamel.
If you want to rock a sparkling white smile, here are the foods you need to eat!
1- Apples, celery and carrots
These healthy fruits and veggies act like natural stain removers by increasing saliva production, which serves as the mouth’s self-cleaning agent. They also may kill bacteria that causes bad breath, and their crunch factor works to scrub teeth clean.
2- Oranges and pineapples
Eating tart fruits such as oranges and pineapples may cause the mouth to produce more saliva, which washes teeth clean naturally. Beware of using lemons directly, because too much acidity can damage teeth.
They may stain your shirt, but they could work to whiten teeth. Strawberries contain an enzyme called malic acid. Try mashing up strawberries and rubbing them on your teeth. Leave for five minutes then rinse with water and brush and floss as usual.
4- Yogurt, milk and cheese
Dairy products contain lactic acid, which may help protect teeth against decay. A study in the journal Dentistry found kids who ate yogurt four times per week had less tooth decay than kids who didn’t eat yogurt. Researchers think proteins in yogurt may bind to teeth and prevent them from attack by harmful acids that cause cavities. Hard cheeses are best for whitening since they help remove food particles as well.
5- Baking soda
One 2008 study found kinds of toothpaste that contain baking soda — long considered a tooth-whitening home remedy — do a better job of removing plaque than kinds of toothpaste without the ingredient.
To try it, your best bet is brushing with a commercial paste that contains the mild abrasive.
Or, once in a while, you can just brush your teeth with baking soda straight from the box.
