Our Orthodontic Services in O'Fallon

Amazing Smiles offers many orthodontic services to fit our patients' needs. Our treatment options include:


· Invisalign®: If you want straight teeth without braces, Invisalign® treatment is a popular way to align your teeth. Children, teens and adults enjoy this treatment due to the transparent appearance of the aligners. The orthodontists at Amazing Smiles are also Diamond Providers — they are in the top 1% of Invisalign® providers worldwide.
· Ceramic braces: Our ceramic braces use clear or tooth-colored brackets for a discreet way to align your smile. Patients who choose ceramic braces will experience the effectiveness of braces without a metallic appearance.
· Metal braces: As the most common orthodontic treatment, metal braces are known for their effectiveness and durability. Patients can customize their braces with a wide array of colored elastics.
· TMJ: Temporomandibular Joint Disorders or TMJ/TMD cause face and neck pain for many patients. Our practice uses cutting-edge digital diagnostic technology to create a personalized treatment plan.
