Dental braces are wire-based appliances that orthodontists use to correct crowded and misaligned teeth or jaws. Many people who need dental braces get them during their early teenage years. However, adults also may benefit from wearing braces. The goal of dental braces is to properly align your teeth and jaws to produce an even bite and pleasing smile.For teens or adults who need minor corrections, an alternative to fixed braces is a series of clear, customized, removable appliances called aligners or invisible braces." Clear aligners may be more expensive than fixed braces
