What Are Lingual Braces?
Lingual braces are orthodontic brackets and wires bonded to the back (lingual, or tongue-side) surfaces of the teeth rather than the front. Because the hardware faces inward, lingual braces are the only truly invisible fixed appliance. Nothing shows when the patient smiles or speaks.
They correct the same conditions as conventional braces: crowding, spacing, overbites, underbites, crossbites, and open bites.
Popular lingual systems include Incognito (by 3M), Harmony, the now-defunct InBrace, and Brava by Brius (the newest entrant). Each uses custom brackets manufactured to fit the contours of each tooth's lingual surface. Treatment typically takes 18–36 months and costs between $7,000 and $13,000 at practices that still offer the category.
Roughly two to three times the cost of every other discreet option.
Clinical note: Bold Bite never offered lingual braces. The decision was made on demand and lab-cost grounds, with clear ceramic braces and aligners covering the discreet-treatment need.
