But why do you need braces spacers and why spacers hurt so much? The answers are right here. Once you decide on getting braces, the first thing your dentist do is place spacers back in your teeth. Braces spacers are placed mainly to create enough room for the anchors used to join the braces. The role of anchor is to slide over your back teeth smoothly and get attached to braces for extra support.
You may not need spacers, but, if you do, having the rubber bands between your teeth will hurt for the first few days. A week after you get your rubber band spacers, your orthodontist will put on your braces [1]. First, your orthodontist will place bands on your back molars, which might cause some pressure or slight pinching. Then, your orthodontist will use special glue [5] to attach a bracket onto each of your teeth.
