We like to see children as early as 3 years old if they are mouthbreathers or at about age 6 or 7. If, however, a child is a nosebreather and has good facial balance, we don't start orthodontics until all 28 permanent teeth are in the mouth. It is our philosophy to give someone the best orthodontic result as early in their life as possible with the least amount of effort on everyone's part! Many of these cases can be treated in a year to a year and a half.
