Doctor Prosterman, Orthodontist

Undergoing orthodontic work is like embarking on a journey. Children, adolescents, and adults experience this journey in different ways. However, they all benefit from an orthodontist who is both highly skilled and genuinely compassionate. If you are searching for an orthodontist for your kids, teenagers, or an adult, consider how these two key criteria combine to place Doctor Beth Prosterman at the top of your list of orthodontists.

Dr. Beth Prosterman is a second-generation orthodontist who followed in her father’s footsteps. Having been exposed to orthodontics her whole life, she could not wait to join her father’s profession.


Following dental school, she completed a one-year multidisciplinary residency program at the Jewish General Hospital. She participated in AIDS research, and published an article on early oral manifestations of HIV. As well, she participated in one of the earliest uses of implants in orthodontics. Subsequently, she began her orthodontic training at the prestigious Ivy League University of Pennsylvania. Upon her return to Montreal, she became an associate professor at McGill University, teaching orthodontics to the residents at the Jewish General Hospital.

Dr. Prosterman attended McGill University where she studied anatomical sciences. She was granted early acceptance to McGill dental school where she finished top of her class.

Doctor Prosterman’s Hands-on Approach

Dr. Prosterman performs the majority of the orthodontic work by herself or with her assistant. She strongly believes that each patient should reap the benefits of her extensive knowledge, skills, and experience in orthodontics.

Young children can be anxious in the face of orthodontic treatment and greatly comforted when they sense the maternal compassion that comes naturally to Doctor Prosterman. Likewise, Dr. Prosterman relates very well to teenagers, having teens herself. Adults who seek orthodontic treatment need a special kind of support and understanding, to which Dr. Prosterman is sensitive.


A beautiful smile can have positive psychological benefits that will last a lifetime.

Her mission is to offer you not only an aesthetic and healthy smile, but an occlusion that is ideal and functional. Dr. Prosterman is passionate about her work and provides a hands-on approach, actively treating every patient at each appointment.

By combining state-of-the-art technologies, professionalism, and kindness, she consciously ensures that the orthodontic experience will be enjoyable, while achieving an excellent treatment result.

It is most rewarding to observe the transformation of a shy, self-conscious child/adolescent into a smiling self-assured person projecting high self-esteem.
