Invisalign®
Invisalign® and Invisalign® Teen are series of clear, plastic aligners that straighten your teeth without the usual noticeable, bulky materials involved with traditional braces. No one will know you’re improving your smile unless you tell them!

Adult Treatment
Think you’re too old for braces? Think again! We are experts at providing orthodontics to patients of all ages, even adults. We provide an assortment of aesthetic adult orthodontic treatment options for patients who’d like to discreetly straighten their smile.

At Johnston Orthodontics, we’re changing lives – one smile at a time!
