These are also known as ‘ligatures' or ‘o-rings'.

The wire plays a big part in controlling how your teeth move, so those elastics have an important job to do. Ligatures are usually available in a wide range of colors.ĭentists use a special tool to fit and remove these little bands, as you'll see in the video below. Larger rubber bands may also be placed between the upper and lower jaw to help with alignment. This is more often the case with children's braces. They are connected to special hooks on the brace brackets.

These are known as ‘inter-arch elastics' and look more like the rubber bands you would use at home. They are less commonly offered in different colors, but they are usually placed on the sides of the mouth so are less visible. If your braces need inter-arch elastics you will need to learn to fit these yourself as they have to be replaced several times a day. Here is a short video showing how a dentist fixes the archwire in place using ligatures:ĭr Claudia karkia is showing how the wire is placed on the braces and then how the color ties are put on. The wire is actually the way the teeth are moved. at the adjustment appointments the wire may be reshaped or changed to a thicker one. There is one type of metal brace which doesn't use colored bands. Self-ligating braces (like Damon teeth braces) have a different style of bracket which lets the wire move automatically, so no elastics are needed to keep the wire in place.
