Legend has it that comedian Rodney Dangerfield once asked his dentist for advice. “Doc – my teeth are yellow. What should I do?” To which his dentist replied: “Wear a brown tie!” Fortunately, these days we can give much better advice than that. Most of us begin life with beautiful sparkly white teeth, but just as the years bring wrinkles, sags, bags and more – the age fairy can make our teeth much more yellow or brown than they used to be.
