Dental braces are orthodontic devices used to correct misaligned teeth and jaws. They consist of brackets bonded to the teeth, connected by wires and elastic bands that gradually move the teeth into proper alignment. Braces can address issues such as crooked teeth, overbites, underbites, and gaps between teeth, improving both function and appearance. Treatment typically lasts between one to three years, depending on the severity of the misalignment and the individual's age and response to treatment. Modern options include traditional metal braces, ceramic braces, and clear aligners like Invisalign.
