Sydney Tooth whitening helps lightens teeth and also helps to remove stains and then discoloration.

The outer part or outer layer of our tooth is called the enamel. The natural color of teeth is created by the reflection and scattering light off of the enamel, it is combined the color of the dentin under it. Our genes have an effect on the thickness and smoothness of enamel. Our thinner enamel allows more color of the dentin to show through. Having rougher or even smoother can also affects the reflection of light and color. Day by day, the thin coating or pellicle forms on the enamel and get stains because the tooth enamel contains pores that can hold stains.
The most popular and very well-known reasons why teeth get yellow or stained are:
– Using tobacco everyday
– Drinking dark-colored liquids like coffee or tea, cola and then red wine
– For not taking good care of your teeth
– And then aging also makes our teeth less bright when the enamel gets thinner then the dentin also becomes darker.
It is also not impossible to get stains inside the tooth, these called intrinsic stains. For example, intrinsic stains can be caused by to much exposure to fluoride like a child while the teeth start to develop. Then trauma also may darken a tooth.
