If your teeth are a little crooked or crowded, you might think it’s too late to do anything about it. After all, when we think of braces, we think of that awkward teenager, too self-conscious to smile and show a mouthful of metal. But increasingly, people of all ages are asking their dentists to fit braces – or aligners – to help them achieve that perfect smile. Some dentists report that 50% of the patients they fit braces on are adults, with 60, 70 and even 80 years olds coming in for treatment. And the good news is that you don’t have to look like the geek from an eighties movie to achieve the desired look.
