    Orthodontic therapy is a relatively new branch of operative dentistry; and although it has existed as a discipline in the United States of America and Canada for many years, its existence in the United Kingdom has become possible as a result of recent legislative change.

    Orthodontic Therapists gain higher qualifications and are trained in programmes accredited by the General Dental Council and the Royal Colleges of Surgeons. They see patients in conjunction with, and under the supervision of Orthodontists.

    The presence of an Orthodontic Therapist brings in fresh energy, makes the practice more efficient and organised for our valued patients. Their experience and qualifications enable them to carry out some orthodontic procedures, while the Orthodontist makes decisions about treatment. The role involves the implementation of treatment plans prescribed by the Orthodontist.

    The Orthodontist can devote more time to diagnosis and treatment planning; patients will get more personal attention from the clinician, thus further enhancing the quality of care we provide; offering more focus on helping patients maintain excellent standards of oral hygiene, more cover for emergencies, additional appointments and flexibility for patients at peak times. Our Orthodontic Therapist helps us remain a modern practice, which provides the highest standards of orthodontic care.
