Braces are orthodontic devices used to align and straighten teeth, improve dental health, and enhance a person's smile. They consist of brackets, wires, and bands that work together to apply gentle pressure to the teeth, gradually moving them into the correct position. Braces can correct a variety of dental issues, including crowded or crooked teeth, gaps, and bite problems. They are commonly used in children and teenagers, but can also be effective for adults. Proper care and maintenance of braces is important for achieving the best possible results.
