It is no secret that Hollywood is first of all appearance, and there is nothing more important than a smile. Many famous actors paid a ton of money to perfect their teeth. The reasons why they resort to this type of service are different. Someone was unlucky since childhood (a vivid example is Tom Cruise), someone just damaged his teeth.
Most celebrities do not admit that smiles are “artificial, ” but it’s pretty easy to notice that they are too perfect to be real.
