Orthodontist Serving St. James, NY

Dr. Duane Shank lives in St. James and has practiced orthodontics eight minutes away, at 200 E Main St. in Smithtown, since 1991. Dr. Shank is a board-certified orthodontist treating children, teens, and adults with braces and clear aligners. Consultations are free.

The short version: he is your neighbor

Dr. Shank, his wife, and their four children live in St. James. He drives down 25A to work the same way most of his St. James patients drive to see him.

There is a version of this page that a practice anywhere in Suffolk County could have written, with a stock photograph and the words “proudly serving St. James.” This is not that. Dr. Shank’s children grew up here, and he has sponsored local Little League for thirty years.

In a place like St. James, that is not marketing. It is just the reason people already know where his office is.

Eight minutes down 25A

St. James to the office is 2.7 miles, about eight minutes.

Take Lake Avenue south to Route 25A, then follow 25A west into Smithtown, where it merges with Route 25 to become East Main Street. The office is at number 200, in the Colonial Building past Town Hall. From the north end of the hamlet near Harbor Country Day and Head of the Harbor, Moriches Road to 25A is the straighter run.

If you have ever driven from the General Store to Smithtown Town Hall, you already know the way. It is the same trip.

Families in the Smithtown school district

Saint James Elementary and Nesaquake Middle School are both Smithtown Central School District schools, and orthodontic treatment tends to begin somewhere between them.

The recommended first evaluation is around age seven, during the Saint James Elementary years. Most children examined at that age do not need treatment yet. What the visit does is catch the smaller group whose crossbite, narrow arch, or crowding is much easier to correct while the jaw is still growing. That appointment is free, and Dr. Shank will tell you plainly if the answer is to wait.

Harbor Country Day families are welcome on the same basis, and the practice also serves Head of the Harbor and Nissequogue, which share the 11780 zip code.

The practical benefit of a shared district is scheduling. Half-days, holidays, and the sports calendar are the same ones we are already working around for Smithtown families, so an appointment that avoids a school morning for one child avoids it for the other.

What treatment looks like here

This is a solo specialty practice. Dr. Shank performs the examination, writes the plan, and makes every adjustment himself; you are not passed between rotating associates over two years of treatment.

Treatment options include metal and ceramic braces, Invisalign and clear aligners, early and two-phase treatment for growing children, retainers, and adult treatment including re-treatment of results that have drifted since a first round of braces years ago.

Dr. Shank is a Diplomate of the American Board of Orthodontics and a Clinical Assistant Professor at Stony Brook University School of Dental Medicine, where he teaches residents in the specialty.

Cost, plainly

One fee covers records, all appliances, every visit including emergencies, and your first set of retainers. In-house payment plans have no interest and start around $150 a month, with no credit check and no outside lender. The practice accepts most dental insurance plans and is not in-network with any carrier, and we say so at the consultation rather than in the small print. HSA and FSA funds can be applied to your balance.

Published Long Island price ranges and the full breakdown are on the financing page.

If you know, you know — Dr. Shank is amazing!! Before my daughter got braces two years ago, we went to several consultations. Every orthodontist suggested removing teeth, using a palate expander, and then braces. Then we met Dr. Shank. He was so patient and confident in allowing her adult teeth to come in naturally before starting treatment. Two years later — almost to the date — her braces are off, and we never had to remove teeth or use a palate expander. He is absolutely amazing. Moms, be patient and listen to Dr. Shank’s advice! Sometimes the best plan is the one that takes a little patience.

We had an excellent experience with Smithtown Orthodontics from start to finish. The entire team is professional, welcoming, and truly cares about their patients. The office is clean and runs on time, which we really appreciate. Dr. Shank took his time to thoroughly explain my child's treatment options and made sure we both felt comfortable and informed every step of the way. Throughout my treatment, we saw consistent progress and felt confident we were in great hands. What really stood out to me was their flexibility and dedication. My college student is only home for a few days at a time which leaves very little room to get everything done however Dr. Shank agreeded to come in on a Saturday during a holiday weekend to accommodate us. That level of care and commitment is truly above and beyond. The staff is also amazing—friendly, helpful, and always willing to go the extra mile to accommodate scheduling or answer any questions. My child's results exceeded my expectations, and I couldn’t be happier with the final outcome. I highly recommend this practice to anyone looking for high-quality orthodontic care!

We just finished a two-year journey with Dr. Shank. We couldn’t be happier with the experience for our child. From the very beginning, the team was personable, warm, and incredibly attentive. One of the things we appreciated most was his honesty—he never over-promised or exaggerated the prognosis, giving us a realistic and clear plan from day one. Scheduling was also a breeze; whenever we needed an appointment, they were flexible and made sure we were seen quickly. After two years in braces, we had a seamless transition into six months of full-time retainer wear. We are now on a ‘need to call’ basis, and our child has a great smile to show for it. We highly recommend them to any parent looking for a team that truly meets your needs. Thank you Dr. Shank for making this a great and easy experience!

We cannot say enough good things about Dr. Shank and his office staff at Smithtown Orthodontics. Dr. Shank is thorough, professional and delivers a great smile! He evaluated our daughter for orthodontics while she was in middle school and gave us a tentative date to come back to see him for further evaluation. When our daughter was ready, his office staff met with us to discuss a payment plan that was right for us and the cost was surprisingly reasonable. Our daughter presented with some complications, such as spacing issues as well as an impacted tooth that went sideways. She had to have oral surgery so that Dr. Shank could work to bring the tooth down into place. In the end, when the braces were taken off, our daughter had a picture-perfect smile! She is so incredibly happy with her new smile. We are very pleased with the entire experience from beginning to end. Any questions or concerns that we had along the way was met with kindness and detailed explanations. We were walked through the entire process feeling as if we knew what was going on every step of the way. Thank you Dr. Shank and your wonderful office for a wonderful experience overall! We would happily recommend you to all of our family and friends for orthodontic care!

My daughter had such a great experience with Dr Shank and all of his staff. Everyone is friendly and helpful all the time. The office always runs on time and gets you in and out quickly. Can’t say enough good things. Dr. Shank asked that we trust him from the beginning and give him time to get her teeth looking their best. He exceeded our expectations. At one point, a wire came loose and we needed an emergency appointment on a Sunday. Dr Shank never hesitated and met us at the office when it was convenient for us. Looking forward to bringing my younger daughter when it’s her turn. Thank you again to everyone in the office.

I found Dr. Shank through the the recommendation of a friend who raved about her daughter's experience and could not say enough positive things about Smithtown Orthodontics. After my first visit to the office, I understood why. There just is something special about Dr. Shank and his staff that sets Smithtown Orthodontics apart. There are so many things I could say about the practice: the staff is lovely, Dr. Shank is wonderful, the office is warm and inviting, making appointments is a breeze. But, what really makes this office special is that Dr. Shank makes you feel like family. He is so kind and compassionate, and he really cares about his patients. It was an absolute pleasure working with him, and I am so pleased with the results on my oldest son's teeth that I just had my middle child in for a consult with Dr. Shank today.
