At Linn Orthodontics, we often see children between 12 and 14 years of age. However, our orthodontist also provides early treatment and orthodontic screenings in Williamsport, Wellsboro and Lock Haven, Pennsylvania, for children at age 7. Every child should have an orthodontic screening. To plan your child’s appointment with Dr. Heister Linn, call one of our conveniently located offices.
