Behind-the-tooth braces are an orthodontic treatment used to straighten and align teeth. They work in a similar way to traditional metal braces, but are less aesthetically noticeable as they are bonded to the back surface of the teeth, on the tongue side. Therefore, they are a good option for patients with aesthetic concerns. Behind-the-tooth braces are a popular option among adults and teenagers with mild to moderate teeth straightening needs. However, it is important for the dentist to assess each patient's needs to determine an appropriate treatment plan.
