Braces do not hurt at all when placed to the teeth. At worst, there might be a few days of soreness or discomfort after the orthodontic wire is engaged into the brackets.
Two common types of fixed dental braces used to realign the teeth: ceramic and metal fixed braces, both of which include brackets affixed to each individual tooth and an archwire that fits into the bracket slot to gently move the teeth into proper alignment. Elastic or wire ties are then applied to hold the wire in place.
It is possible that some teeth may have to be extracted to increase the amount of available space for properly aligning the teeth if it is determined that malocclusion has caused overcrowding . Fixed dental braces are used to treat a wide variety of malocclusions, including overbite, underbite, crossbite and overcrowding.
