Orthodontist Serving Lake Grove, NY

Smithtown Orthodontics treats Lake Grove patients from 200 E Main St. in Smithtown, about eleven minutes west along Route 347. Dr. Duane Shank is a board-certified orthodontist providing braces and clear aligners to children, teens, and adults. Consultations are free and payment plans carry no interest.

One road, eleven minutes

Lake Grove and Smithtown sit at opposite ends of the same corridor. Route 347 runs from Smith Haven Mall west through Nesconset and into Smithtown, where it meets Route 25 at the village. Turn east onto East Main Street and the office is at number 200, past Town Hall, in the Colonial Building. It is 4.4 miles, and 347 is a road most Lake Grove residents are on several times a week anyway. If you have driven from the mall into Smithtown for anything else, you have already made the trip. From the Hawkins Avenue and Moriches Road side of Lake Grove, Middle Country Road west to 347 is the straighter approach. From the neighborhoods south of the mall, Alexander Avenue to 347 avoids the retail traffic entirely, which matters more on a Saturday than a Tuesday.

Lake Grove is Brookhaven, and we will not pretend otherwise

Some practices near a town line write as though every nearby hamlet belongs to them. Lake Grove is in the Town of Brookhaven, and its children attend Middle Country Central School District schools, feeding up to Centereach High School. That is a different town and a different district from Smithtown. What Lake Grove and Smithtown share is the road, and the fact that a specialty orthodontic practice does not exist on every corner. Lake Grove has dentists. For an office limited to orthodontics, most Lake Grove families drive, and eleven minutes is a short drive for two years of care.

The people you will actually see

This part is worth more than any list of appliances. Smithtown Orthodontics is a solo specialty practice, and it is small on purpose. Dr. Shank performs every examination, writes every treatment plan, and makes every adjustment himself. Around him is a team that has been in place for a very long time: its two most senior members have twenty-five and thirty years in this office, including the coordinator who will walk you through your treatment plan and the financial arrangements before you commit to anything. Lake Grove families searching for an orthodontist have been finding this practice through our team page for a while now. This page exists so the geography lands in one place and the people keep their own.

Treatment for Lake Grove patients

Children, teens, and adults, with a first evaluation recommended around age seven while the jaw is still growing. Options include metal and ceramic braces, Invisalign and clear aligners, early and two-phase treatment, retainers, adult treatment and re-treatment for results that have drifted since an earlier round of braces, and emergency appointments for loose brackets and poking wires, which are covered by the treatment fee rather than billed on the day. 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.

Fees and scheduling

One fee covers records, all appliances, every visit, and the first set of retainers. In-house payment plans have no interest and start around $150 a month. Most dental insurance plans are accepted; the practice is not in-network with any carrier and says so up front. HSA and FSA funds can be applied. Detail is on the financing page. Appointments start at 8:00 AM Monday and Thursday and run to 8:00 PM on Tuesday, with Wednesday and Friday morning sessions.

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.
