At Bay Area Orthodontics at our Sunnyvale office we offer a variety of braces Metal braces are now lighter in weight and structure than they used to be. They are made from high-grade stainless steel and have metal brackets that are attached to each tooth using a type of cement. The brackets are linked to each other with a thin archwire, which puts pressure on the teeth to cause them to move slowly into the correct position. The archwires are connected to the brackets using tiny elastics known as ligatures or o-rings, which will change each time the braces are tightened.
