Why Us

Our patients choose us because they can clearly notice our true passion for creating beautiful, healthy smiles that will last a lifetime. It is our goal to provide all of our patients with a positive experience that builds confidence, trust and empowers them with knowledge.

Our patients feel as if they are part of our Udis & Sethi Orthodontics community because they are treated just like family. This is best exemplified by the fact that over the decades we have proudly served as the orthodontists of choice for multiple generations within the same families.

High-End, Boutique Practice

​It is becoming far too common in healthcare that when you go into an office, you have no idea which doctor you are going to see for your care. We pride ourselves in being a family-owned and operated small business. In our office, you are not just another number. We are committed to ensuring that you feel as though you are receiving service of the highest quality possible. Even when you need to see another provider, our practice works with the best dentists and dental specialists around to make sure our patients’ health is taken care of the right way.

What does all that mean? It means that you will see your doctor every single visit, you will be taken care of by our wonderful staff, if you have an emergency you will be able to speak directly to the doctor even after hours, there will be little to no wait times when you come in for appointments, there will be flexibility in making your appointments, flexibility in payment plans with NO INTEREST, ease in submitting to insurance (our front desk will submit for you), you will receive a FREE electric toothbrush in your Braces Care package when you start full treatment, monthly contests for our patients where you can win prizes, and you take home a surprise gift when you get your braces off!

We want to be high-end in every single way, except the cost. 

Customized Treatments and Superior Results

Patients choose us for our superior treatment outcomes, strong passion for perfection, and endless commitment to our patients’ care. Being a high-end boutique practice allows us to take our time to carefully create customized treatment plans for each patient that makes sense for their health and lifestyle. We don’t just tell, we emphasize showing and teaching our patients so they know the “why” — our doctors are teachers just as much as they are orthodontists. 

Even after your treatment is finished, we offer our patients a two-year retention program to make sure your perfect smile lasts.

Personalized Attention and Care

Our patients have the doctor’s undivided, personal attention during every visit. We prioritize spending time with our patients and learning about them. When you come for your visits, you will see a doctor every time, and Dr. Sethi or Dr. Udis will spend quality time treating you, listen to any concerns you may have, and answer all your questions.

Starting from the very first visit in our office, you will quickly see why our patients love us. The initial exam and consultation is one of Dr. Sethi’s favorite appointments because that is when he likes to teach his patients and parents all about what makes a good bite and a beautiful smile. He takes his time with you in a way you will not find at other offices. That’s the bar we want to set for the rest of your care. Come see the Udis & Sethi Orthodontics difference.

Flexibility and Convenience

We offer flexible weekday appointments, including evening hours so that we can accommodate our patients’ schedules. We value your time, which is why we always make an effort to see our patients within five minutes of their scheduled appointment (and get them out the door on time too!).

We want our patients to live their lives without worrying about their teeth – so they can count on our full-time emergency coverage on-call service which connects you directly with our doctor.

We also don’t want our patients to worry about paying for orthodontics, so we handle submitting to your insurance company, and work with our patients to build individualized payment plans with ZERO interest.

Where Dentists Take Their Kids

When our area’s dentists and their staff choose an orthodontist for their children, they choose Udis & Sethi Orthodontics! Come see why. 

Highest Quality Doctors

Our patients know that they are in good hands. Our doctors are dual-ivy league educated, board-certified orthodontic specialists with training and experience in today’s most technologically-advanced treatment techniques. The practice has been consistently selected as a “Top Dentist” in the Greater Philadelphia area for nearly 15 years in a row!

Our doctors are teachers and mentors just as much as they are orthodontists. Both Dr. Udis and Dr. Sethi are on staff at Abington (Jefferson) Hospital as faculty attendings and are teaching and training the next generation of dentists.


Advanced Technology

Our patients benefit as we utilize the latest technology, employ the most advanced techniques, and use only the most effective appliances in the industry. We offer traditional metal braces, more esthetic premium gold/champagne-colored braces, Invisalign Clear Aligners, retainers, growth appliances, and more.

We use iTero 3D digital scanners (no more GOOPY impressions for all) and state-of-the-art digital imaging (which minimizes radiation exposure and allows for more accurate diagnosis).

We are the only practice in the area that is part of Oral-B’s OrthoEssentials Program, and we give you a FREE Oral-B electric toothbrush and a care package with superfloss, Fluoride mouthwash and other goodies the same day you get your braces on with every comprehensive braces treatment!

iTero Digital Scanner: No more Goopy Impressions!

Thankfully, old-school GOOPY impressions are no longer the only option. We were one of the first practices in the area to use the iTero 3D digital scanner many years ago. The digital scanner is all about keeping you comfortable, while delivering precise imagery without the goop associated with the older impressions.
