Does any one in the world wants a yellow teeth? or
Any one in the world does'nt want a white teeth?
These are the two wishes makes the tooth paste business as number one in the world.
Every one should know why there are so many shades of teeth.
Does a yellow teeth means ugly teeth.
The colour of your teeth is an optical phenomenon. It depends on the thickness of the enamel. The inner layer of the tooth is called dentin, which is yellow in colour. If the overlying enamel is thin the colour of dentin is visible through the enamel giving the tooth yellow colour. If the enamel is thick the underlying dentin is not visible so tooth appears white. The whiteness of tooth depends on the thickness of enamel. Genetic also plays a role. Usually a fair complexioned person will have yellow shade and a dark complexioned person will have white shade.
So the colour of your teeth is not going to be changed permanently by your tooth paste.
Yellow or white teeth keep it clean.
