When most people think of metal braces they think of the big clunky braces of the past. They were extremely uncomfortable and more than capable of cutting your lips. From a cosmetic point of view they were, at best, unattractive and are wholly responsible for the stigma attached to braces today. However, times have changed and so have braces.
Modern braces are smaller and more comfortable than old fashioned braces. They have what is called a low profile design, which is less irritating to your lips. They also have special contours to make your orthodontic treatment go faster and be less painful.
Braces now use new plastics and bonding adhesives rendering metal bands a distant, somewhat painful memory. Wire and brackets can be “super-glued” directly onto the teeth making them far more secure. There are even some braces that seem “invisible”.
