Near the back of the mouth on the molars or premolars is a band of metal. There are different sizes, and the tightest fitting band is selected. Using dental cement they are sealed to the teeth, fluoride is mixed in with the cement so there is no damage during the treatment. These bands keep the metal wire tight against the back teeth.
Each tooth will have a bracket, which holds the wire against the teeth. The wire fits into a tiny slot on the bracket and is held there securely. The brackets are sometimes cemented right to the teeth, or they are attached to a band instead.
This is the wire that is going through the brackets, it is specifically shaped to fit the mouth of the child and to fit into the brackets used. The pressure which guides the teeth into the right position comes from the arch wire.
These are tiny rubber bands. Their purpose is to tie the arch wire to the bracket. This keeps the wire in place and secures it.
Depending on the placement of the teeth, sometimes hooks are found on the brackets. Rubber bands are then attached to the hooks to help guide teeth into place. The rubber bands will have different strengths depending on the amount of movement needed. They may no longer be necessary by the end of treatment.
These are commonly used for children who still have teeth coming in. The coil spring fits over the arch wire and creates space for teeth. If a tooth is coming in but there is not enough room for it, a coil spring will help make space.
These are some of the common parts of modern braces. Some kids may need additional parts on their device to treat specific problems. Understand how this dental device works and enjoy a beautiful and healthy smile!
