Lingual braces function much like traditional braces by straightening and aligning teeth. Unlike standard braces, their brackets, wires, and elastics are fixed on the back of the teeth. This makes them virtually unnoticeable to others. They can fix overcrowded teeth by applying pressure onto each tooth and gradually moving them into position.

Lingual braces can come customized for patients with more complex cases. The lingual braces can just be attached to the top front teeth for minor defects. Lingual braces are also known to be less likely to break off compared to traditional braces. However, not everyone is a suitable candidate for this treatment. For example, severe overbites can cause the brackets to fall off frequently. 

Lingual braces treatment begins with taking X-ray scans and examinations of the mouth.  These help to assess the strength of the teeth and gums. Dentists also take a mold of the mouth before creating a personalized treatment plan for each patient. Usually, patients can avoid tooth extraction unless the overcrowding is too severe. Orthodontists insert the lingual braces about four weeks after the initial appointment, and patients visit their clinic every weeks for wire tightening. In the beginning, patients may have some issues with speech and tongue irritation, but gums and cheeks should not be affected.

Patients need to avoid hard foods that could break the braces, or sticky, chewy foods that may get stuck to the wires and bracket. Since the brackets are placed behind the teeth, patients need to brush the area properly to prevent a build-up of bacteria. The typical treatment length for lingual braces is 18-24 months.
