Why do we need tooth whitening?

The natural white colour of teeth is derived by the reflection and scattering of light in the enamel. The smoothness and thickness of the enamel is affected by your genes.

Daily a thin layer forms on the enamel and results in stains. Consuming tobacco, drinking dark coloured liquids like wine and not taking proper care of your teeth are some of the most common reasons for teeth getting stained and de-colored.

Another reason for losing the brightness of teeth is aging as it makes the enamel thinner and the dentin becomes darker.

Intrinsic stains exist inside the tooth. It is caused by either too much fluoride exposure as a child while teeth are developing or tetracycline antibiotics. It can stain a child’s teeth if it’s taken by a mother during the second half of pregnancy or by a child who is younger than 8 years. Tooth whitening is most effective on surface stains i.e. extrinsic stains.
