Celebrating 25 years in East Cobb

Here at Johnston Orthodontics, we strive to provide the highest quality of orthodontic care to our patients in and around the East Cobb and Marietta area. Dr. Mark Johnston knows what a significant difference in health and self-esteem a beautiful smile can make, which is why Johnston Orthodontics is dedicated to giving each of our patients the beautiful smile they deserve!

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 or patients who’d like to discreetly straighten their smile.

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.
