The smiles of most folks are a tad more monotonous while stars and models may sport pearly white teeth. But this shouldn’t be overly surprising: that dreaded yellow hue cans change the color of your teeth and turn them.
Most causes of tooth discoloration fall into two broad categories: intrinsic and extrinsic blots.
You’ll locate extrinsic spots at first glance of the enamel, the hard, outermost layer of your teeth. These stains usually grow because of your diet.
Unsurprisingly, dark-colored foods and beverages — including coffee, colas, black tea, red wine, dark sauces and assorted fruits, like grapes, blueberries and pomegranates — have the best possibility to stain teeth. These things are high in chromogens, pigment-producing materials with a penchant for sticking to tooth enamel.
Drinks and acidic foods can worsen matters by making it easier for chromogens to latch onto the teeth and eroding tooth enamel. A bitter compound found in wine and tea, tannin, also helps chromogens attach to tooth enamel.
Furthermore, smoking and chewing tobacco are well known culprits behind extrinsic spots, as is inferior dental hygiene, allowing dental plaque to accumulate on the teeth.
Inherent spots occur inside the tooth, when the light change -conducting properties of the enamel as well as the underlying dentin.
Numerous medicines may cause intrinsic spots. If kids take the antibiotics tetracycline and doxycycline while their teeth are still growing (before the age of 8), their teeth may turn brownish yellow.
During maturity, chlorhexidine, an antiseptic used in prescription-strength mouthwash to treat gingivitis, can cause discolorations. Likewise, the acne-fighting drug minocycline, a derivative of tetracycline, spots teeth. Even relatively common drugs, like blood pressure medications and antihistamines, can sometimes yellowish teeth.
Excessive fluoride ingestion and chemotherapy directed in the head and neck also result in stains that are intrinsic.
Aside from intrinsic and extrinsic spots, two other factors can contribute to yellow teeth: genetics and aging.
Similar to your complexion or the color of your eyes, you could just be born with teeth that appear more yellowish (or more white) than other people’s teeth. A part of this has to do with all the thickness of your enamel, which will be semi-translucent. In other words, for those who have thin enamel, the true color of your yellowish dentin will glow through.
Similarly, your enamel thins as you age, making your teeth appear yellow.
