Does insurance cover teeth whitening?

Teeth whitening form a part of cosmetic value; so many insurance companies do not cover it. The very nature and principle of insurance companies is to cover only health risks that are contingencies and uncertain and not those that are certain like the whims and fancies of people to improve their personal appearance. It is supposed that insurance companies would have to raise their premium considerably if they had to cover the growing interest of cosmetic procedures that has gathered momentum in the recent days.
