Orthodontist in Londonderry, NH

Dr. Polgrean and her highly trained staff have been creating beautiful smiles in Londonderry, Derry, Hudson, Salem, Manchester, Litchfield, Windham, Candia, Raymond, Hooksett, and surrounding areas for over 25 years. Our doctor and staff attend numerous continuing education courses throughout the year as part of our commitment to providing you with the highest quality of care.

Our dedication to providing extraordinary personal service with compassion and consideration to the unique needs of each of our patients is our top priority. We feel open communication is extremely important in creating a positive environment for our patients and insuring a successful treatment outcome.

At Apple Tree Orthodontics we utilize the latest technological advances in the profession to achieve unsurpassed results for our patients. In addition to “clear” braces, Invisalign clear aligners, and Teen Invisalign clear aligners, we offer low radiation digital radiography, and a “no impression” intra-oral scanner eliminating the need for traditional impressions. We have extensive experience in treating more complex cases which may require orthodontics in conjunction with jaw surgery. Our team works closely with several oral surgeons in the Boston area.

Here at Apple Tree Orthodontics, we recognize that each patient has unique needs, and we pride ourselves in tailoring our treatment to meet these requirements. Whether you are an adult, adolescent or child, our knowledgeable team is committed to helping you achieve the smile you deserve – a healthy, beautiful, self-confident one that will last a lifetime!"
