Braces are devices which are used to straighten teeth, correct bite problems and fix irregular teeth.
They are made of three basic parts:
– Bonding (or band)
– Arch wire
The bonding is used to fix the brackets to the teeth.
The arch wire goes through the brackets and is held in place with small rubber bands.
The brackets and arch wire work together to move the teeth into new positions to straighten the teeth.
The arch wire works by putting pressure on the brackets to help move the teeth into the desired new position.
When pressure is applied to your teeth like this, they loosen slightly from the gums. Bone grows in to support the tooth in its new position but this takes time so the process needs to be done slowly.
That’s why you may have to wear braces for about two years and adjustments are only made every few weeks.
The arch wires work because they want to keep their original shape and will exert a great deal of pressure to do this. It is the combination of this aim of the arch wire and the person’s body heat that puts pressure on the teeth.
Braces are not always enough on their own to complete the task so the orthodontist may also use rubber bands or other devices to help pull the teeth in the correct direction.
After you have finished with the braces, you may need to wear a Retainer for a few months to hold the teeth in position until the bone has fully grown into place.
