Whitening Yellow Teeth
OTC products such as Toothbrush and Whitening Pen can lift yellow tones in your teeth by removing stains and providing a mild bleaching effect when used as directed. Other products include whitening trays and even mouthrinses.
Discolorations are generally responsive to bleaching procedures, and dentists can advise on how to whiten yellow teeth depending on your case. Your dentist can provide bleaching kits to take home and use over a period of time, as well as in-office bleaching procedures. However, he or she might recommend waiting until all your child's permanent front teeth have appeared before using a bleaching treatment, so that newer teeth aren't a different color than bleached baby teeth.
With so many ways to treat yellow teeth, there's no reason to hide a beautiful smile.

ssing doesn't help improve your yellow teeth, it's time to consider other options. Teeth become yellow due to stains – both deep and surface-level – as well as other causes that sometimes aren't under our control. Whether the discoloration is due to staining or other factors, several over-the-counter (OTC) products can improve tooth color, and your dentist can also offer preventative advice on how to whiten yellow teeth.
What Causes Yellow Teeth?
Although coffee and cigarettes leave stains on your teeth over time, thin tooth enamel also makes teeth look yellow. Tooth enamel is the hard, white surface of your teeth, and underneath it is a pale brown substance called dentin. Thick enamel looks white, but thin enamel allows dentin tones to show through, making teeth look yellow from the outside. Enamel naturally wears thin as people age, but acids from foods and drinks such as sour candies, oranges and soda also thin the enamel by eroding its surface. Carole Palmer, head of the Division of Nutrition and Oral Health Promotion at Tufts University, tells Tufts Now that even chewable vitamin C tablets are acidic.
Saliva neutralizes acid and washes it away, but people suffering from dry mouth miss out on this protective effect. For example, children who breathe through their mouths due to blocked nasal passages can prevent saliva from remoisturizing the mouth when it's closed – putting them at risk of developing thin tooth enamel. Medline Plussays that in rare cases, inherited diseases also cause very thin enamel.
