Orthodontist Serving Commack, NY

Smithtown Orthodontics provides braces and clear aligners to Commack families from 200 E Main St. in Smithtown, about twenty minutes east on Jericho Turnpike. Dr. Duane Shank is a board-certified orthodontist. Consultations are free and payment plans run in-house with no interest, starting around $150 a month.

The town line runs through Commack

Most people who live in Commack know this and most people who do not, do not: Commack is split down the middle between the Town of Huntington and the Town of Smithtown. Commack High School is on the Smithtown side. So is Hoyt Farm Nature Preserve, the 133-acre park on New Highway with the sugaring shack and the trails, which the Town of Smithtown bought in 1965 and still runs. If you have taken a child there for the maple festival, you were in a Smithtown town park in Commack. That is the honest basis of this page. Smithtown Orthodontics is not around the corner from you. It is a specialty practice serving the town half of Commack is in, and it has been there for over thirty years.

Getting here from Commack

Roughly twenty minutes, and it depends which end of Commack you start from. Jericho Turnpike east is the direct route. Jericho becomes Route 25, which becomes East Main Street through Smithtown village; the office is at number 200 past Town Hall. From the northern end of Commack near the high school, Commack Road north to 25A and then east is often smoother. From the southern end near the Long Island Expressway, taking 454 across to Route 111 and north into Smithtown avoids the Jericho lights entirely. We will not pretend it is a five-minute trip. It is a twenty-minute one, made every four to eight weeks during treatment, and plenty of Commack families decide the specialist is worth it.

Clear aligners, braces, and how to choose

If you are weighing the two, here is the short version. Clear aligners, including Invisalign, are removable, close to invisible, and comfortable. They handle crowding, spacing, and rotation very well. They require you to wear them 20 to 22 hours a day, and they are less predictable for real bite correction, significant vertical movement, and closing extraction space. Braces are fixed, so compliance is not a variable, and they handle the difficult mechanics more reliably. Ceramic brackets make them far less visible than most adults expect. Dr. Shank treats with both and has no reason to sell you either one. At the consultation he examines the case and tells you which tool it calls for, including when aligners would be the wrong choice. That judgment is what two to three years of specialty residency after dental school actually buys.

Payment plans, in plain numbers

The practice runs its own payment plans with no interest. Monthly payments start around $150, with the down payment and schedule agreed at the consultation. There is no outside lender and no credit check, and because there is no interest, what you pay in total is what you were quoted. One fee covers records and X-rays, all appliances, every appointment including emergency visits, and your first set of retainers. The practice accepts most dental insurance plans and is not in-network with any carrier, which we tell you before you commit. HSA and FSA funds can be applied to your balance. Published Long Island price ranges are on the orthodontic financing page, and Invisalign specifically on the cost of Invisalign page.

Who Dr. Shank treats

Children from about age seven for a first evaluation, teenagers, and adults, including adults being re-treated after an earlier round of braces has drifted. 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 orthodontic residents. He examines, plans, and adjusts every case in the practice himself.

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.

Frequently Asked Questions

We understand that choosing an orthodontist is an important decision. Below are answers to some of the most common questions we receive from patients and families in Commack about braces, Invisalign®, financing options, insurance coverage, and orthodontic treatment.

Smithtown Orthodontics serves Commack with Invisalign and other clear aligners, and runs its own no-interest payment plans starting around $150 a month with no credit check. The office is at 200 E Main St. in Smithtown, about twenty minutes east on Jericho Turnpike, and consultations are free. Dr. Duane Shank is a board-certified orthodontist.

Published ranges for this part of Long Island run roughly $3,000 to $7,000 for metal braces and $4,000 to $8,000 for ceramic, depending on how long treatment takes and how much movement is needed. Your own fee is quoted in writing at a free consultation. At this practice one fee covers the whole course of treatment, including retainers.

Start with what the case needs rather than what you would prefer. Aligners suit crowding, spacing, and rotation, and need 20 to 22 hours of daily wear. Braces are more reliable for bite correction, extraction cases, and anything where compliance is uncertain. An orthodontist can tell you which applies after examining the teeth, which is a fifteen-minute answer at a free consultation.

Partly. Commack is split between the Town of Smithtown and the Town of Huntington. Commack High School and Hoyt Farm Nature Preserve, a Town of Smithtown park at 200 New Highway, are both on the Smithtown side of the line.

About 7.3 miles and twenty minutes, mostly along Jericho Turnpike heading east, which becomes East Main Street through Smithtown village. There is parking at the building.
