Why Do Teeth Become Yellow?

Many adults are obsessed with having the whitest teeth, and will undergo bleaching and expensive laser treatments to ensure they have the whitest teeth possible. These treatments only last for six months or so. Once the teeth are very white, even the slightest stain shows up and looks terrible. Whiteness of teeth depends on the color of the enamel and the underlying dentin in the tooth. Dentin is naturally yellow and begins to shine through the translucent enamel. Whitening agents like hydrogen peroxide diffuse through the enamel to actually bleach
the dentin. However, if we want to make our teeth whiter, one natural alternative is so re-mineralize our tooth enamel.

If we look at children, they often have perfectly white teeth. How can we retain our natural white teeth? Are there any natural ways of ensuring our teeth stay as white as they were when we were kids?

The first natural way is simply prevention. We avoid the foods that cause staining. Most children have the great advantage that they are not drinking red wine, tea, smoking, drinking coffee or eating curries. Avoiding foods that stain is critical to maintaining white teeth.

The second natural way is really not understood by most people. As we age, our teeth start losing enamel from the constant process of re-mineralization and de-mineralization that is occuring in our mouths. Enamel is the hardest substance in the body, and does an incredible job when it comes to large impact force and the constant chewing action. Teeth are very strong. However, mother nature did not count on the modern diet when we evolved our teeth with 96% mineral content. Over time, our acid diet leeches away at the minerals, causing de-mineralization.

Our thin layer of enamel is thinned further until the underlying dentin begins to appear underneath, causing discolouration of the tooth,

In many instances yellow teeth are not stained yellow, the lose enamel in the de-mineralization process and appear darker.

Stengthen the enamel by re-mineralization, and you can turn your teeth whiter naturally.
