Dental braces are devices used by orthodontists to correct alignment issues in the teeth, such as crooked teeth or misaligned bites. They consist of brackets that are attached to the teeth and a metal archwire that connects them, applying constant pressure to gradually move the teeth into the desired position. There are different types of braces, including metal, ceramic, and clear aligners. While treatment can last from several months to a few years, the results often lead to significant improvements in oral health and aesthetics, providing a more aligned and functional smile.
