One of the big developments of the past few decades is the combination of cosmetic and medical. We see this most clearly in the rise of plastic surgery – it's a procedure that needs a doctor to carry it out, but it is not specifically necessary – at least not for the purposes of staying alive and healthy. Teeth whitening is one of these things – a cosmetic dentistry procedure that may not be absolutely necessary, but with results desirable enough to make it worth spending what it takes to have the benefit.
There is a lot of debate about teeth whitening – is it a matter of pure vanity, or something more? Someone who has had cosmetic dentistry may well receive some mockery from friends. Outwardly, it seems to be a vain thing to do. On the other hand, having your teeth whitened is something which has genuine positive benefits. It can be beneficial for your employment prospects, and not only if you are an actor or a model.
Sitting in a job interview, you want to be as confident as possible, and exude an air of control. One of the things that you will particularly want to do is smile at the people across the table from you. If you feel confident to do this, you can be reasonably liberated in the interview and give the best account of yourself. This in itself can be a financially beneficial situation – so having good, white teeth is about more than just looking good – it can be about feeling good and advancing your life.
