Orthodontics is the dental science of straightening crooked or misaligned teeth to create beautiful smiles! In traditional braces, brackets are placed onto your teeth and wires move them to the desired position. A modern technique called Invisalign® uses “invisible aligners” to create tooth movement. The average treatment time is about 18 months depending on your condition and age. The best time to start treatment is after all the adult teeth have come into the mouth, at about age 11 to 13.
