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.
Clear aligners are likely useful for moderate front-teeth crowding. In those with teeth that are too far forward or backward, or rotated in the socket, the aligners are likely not as effective as conventional braces.
