How many times have you seen an advertisement for a toothpaste telling you that unless you have shiny white teeth, you need to take care of your dental hygiene? Sparkling white teeth have always been the standards for dental hygiene with multiple brands using this image to sell their products. 

But according to a report in Science Focus, the strongest teeth are slightly yellow in colour.

People often believe that unless their teeth are white as paper or piano keys, they don't have great teeth. This has been proven to be scientifically wrong as the natural colour of teeth is slightly yellow or a little grey-ish shade of it. Due to heavy smoking, you might end up with slightly darker teeth. 

The enamel is blueish white colour, but it is also somewhat translucent, so the yellow of the dentine beneath it shows through to make the overall colour of the teeth either light grey or light yellow. Glowing white teeth may look better but they're not as resistant to decay as the yellow ones.

Using products to whiten up the teeth may strip it of the yellow layer but they also put you at risk of terrible dental hygiene. It increases the chances of getting a cavity. As you grow older, the enamel gets scraped off and the teeth seem yellow but that has nothing to do with the health of your teeth. 

This is proof how a particular industry has set up a notion in our heads and now it's popular belief that you're not leading a healthy life if you don't adhere to their standards.

Next time before you judge someone for yellow teeth, always remember that they may have healthier teeth than you do.
