What the practice treats

Dr. Shank treats children, teenagers, and adults, and he plans and adjusts every case himself. This is a specialty practice, so orthodontics is the only thing done here.

The area we serve

Most patients come from Smithtown itself, and from the hamlets around it: St. James and Nesconset, both under ten minutes; Kings Park and Hauppauge, in the Town of Smithtown; Lake Grove down Route 347; and Commack to the west. Nearly every family in the Smithtown Central School District is inside a fifteen-minute drive. The office sits close to several schools. Smithtown High School East is about a mile and a half away. Accompsett Middle School and Great Hollow Middle School are both within two miles, Smithtown High School West about four, and St. Patrick School under a mile. Dr. Shank sponsors teams at four of those schools and has sponsored local Little League for thirty years.

What a first visit costs

Nothing. The initial consultation is free, and it is a real examination rather than a sales appointment. Dr. Shank looks at the teeth, tells you whether treatment is needed, explains the options, and gives you the fee in writing. If nothing needs doing yet, he will say so and ask you to come back in a year. If treatment is right for you, the practice runs in-house payment plans with no interest starting around $150 a month, accepts most dental insurance plans (though it is not in-network), and accepts HSA and FSA funds.

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.
