Board-Certified Orthodontics That Looks Beyond Straight Teeth
Crooked teeth, crowding, gaps, or a bite that doesn't feel right can affect more than photographs. They can influence how comfortable you feel smiling, speaking, and interacting with other people.
Create a more balanced smile by improving tooth position, proportions, symmetry, and overall smile design.
Feeling comfortable with your smile can make it easier to smile, speak, and show up with confidence.
A properly aligned bite helps your upper and lower teeth work together more comfortably and efficiently.
Better-aligned teeth can be easier to brush and floss, helping you maintain a cleaner, healthier smile.
Healthy jaw development and proper oral function can help support a more open airway, better breathing, and healthier growth.
At Beyond Smiles, we don't begin with the question, "Which braces should you get?" We begin by understanding the problem. Dr. Isaak Yelizar evaluates tooth position, bite relationships, jaw development, facial proportions, smile aesthetics, and airway-related concerns when relevant. From there, treatment is designed around what you actually need.
Orthodontic Problems
Sometimes the first sign of an orthodontic problem isn't a crooked tooth.









Nobody should have to experience embarrassment caused by their smile or feel less confident in public when taking selfies with friends. In order to create highly artistic smiles that exude energy and confidence, our orthodontist has perfected specific protocols that allow us to achieve life-changing, inspiring results. The main focus of our treatment is not to “align” your teeth, but to find a unique balance between the art and science of orthodontics, and apply it towards creating your stunning, aesthetically pleasing smile.
Like you, we are frustrated by people or nearby companies that over promise and under deliver. We are not a franchise, we are a privately owned orthodontic clinic. From the moment you call us, and until your last farewell retainer check visit, our goal is to give you the best patient experience possible! Every aspect of your visit has been carefully considered, and your satisfaction made our top priority. We won’t let you graduate from our clinic until we are completely satisfied with your final smile result.
Have you ever been told your option are metal braces on the outside of the teeth? Most of the time, the options offered to the patients are dependent on the practitioner’s experience and expertise in using certain orthodontic techniques. As specialists in orthodontics, rather than limiting to one type of braces, we believe in offering all of the treatment options to you. Hidden braces (Brius, Inbrace, Incognito), Clear porcelain braces, and lastly metal traditional or self-ligating braces are all the options offered at our practice. Rest assured the option recommended by Dr. Yelizar and chosen by you, will result in the best treatment outcome and a beautiful, stunning smile.
We understand that everyone’s time is of the essence. That’s why we offer after-school, evening, and weekend appointments in order to accommodate your or your child’s busy schedule. Specific times are allocated for each appointment, allowing us and you to run on time. Our goal is to always meet your expectations.
Confidence, trust, and clinical skills of the provider are some of the most important factors that should be considered when choosing an orthodontist in your area. One of the ways Dr. Isaak demonstrated that was by reaching the pinnacle status of his profession. Dr. Yelizar is very proud to be a Board Certified Orthodontist. This accomplishment is rare, while all orthodontists have to complete an accredited residency and are licensed, only about 30% of orthodontists are board-certified. This devotion to his profession is what will make your smile memorable.
No one likes any surprises. At our practice we believe in honesty and transparency. Once you begin the journey with us we will guide you every step of the way. With this promise from the beginning and without any surprises along the way, the patient always knows the services they’ve acquired. We understand “things happen” and it’s our mission to always be there for you. A tranquility that is now, more than ever is appreciated.
At our practice we realize the importance of providing the best value for your money. We believe that everyone deserves a beautiful smile and finances shouldn’t be a smile breaker. We offer multiple, customizable, interest-free, in-office payment options that can make financing your orthodontic treatment affordable. Our team is ready to work with your dental insurance provider to help you exhaust your benefits. FSAs and HSAs can be applied towards your treatment allowing you to use your pre-tax money. Patients can apply for Lending Point, and other third-party financing agencies that can extend their payments with low interest for up to 60 months. Are you budget ready to transform your smile?
Let’s face it, our daily lives are very hectic. There will be times when you will forget to wear your retainers which will cause your teeth to shift. Our Smile Guarantee Program will allow you to come back and receive re-treatment at a fraction of the cost of the original treatment. You will no longer need to worry about paying thousands of dollars, you’ve initially paid.
Dr. Isaak Yelizar is a board-certified orthodontist whose approach goes beyond simply aligning teeth.
Every patient begins with a diagnosis. That means understanding how the teeth fit together, how the jaws relate, how the smile fits the face, and whether growth, airway, or functional considerations should influence treatment.
That comprehensive approach allows Dr. Yelizar to treat everything from straightforward crowding to complex bite and jaw-development problems using traditional braces, clear aligners, hidden orthodontics, MARPE, and other advanced techniques.

“I recently finished my orthodontic treatment with Dr. Isaak Yelizar and his amazing team after almost two years, and I am so happy with the results! From day one, Dr. Yelizar was attentive, patient, and genuinely passionate about helping me achieve the smile of my dreams.
Growing up, my teeth were one of my biggest insecurities. I was so self-conscious that I rarely smiled with my teeth showing. Now, I can’t stop smiling because I love how they look! Beyond the physical results, I just feel so much more confident, and I’m incredibly grateful for that. I’m so glad I chose you for my orthodontic treatment.
If you’re considering braces or orthodontic treatment, I truly can’t recommend Dr. Yelizar and the team at Beyond Smiles Orthodontics enough. They gave me a smile I’m proud to show off!”
Ruby S., Syosset, NY
“First off, the staff is super friendly, and I always felt comfortable in the chair I dreaded most (I always hated the dentist)! Second, Dr. Isaak Yelizar was the only dentist that agreed to fix my teeth without pulling any out or without major surgery. I wore regular metal braces for 16 months, and the difference in my smile is incredible. For a long time, I always covered my teeth when I smiled or laughed. Now I’m all smiles and always showing my teeth off. I cannot believe how straight they are! I highly recommend Dr. Yelizar… he’s very informative, professional and knows what he’s doing. The results were worth every penny! Thank you so much!”
Andreia D., Syosset, NY
“I was highly recommended by my general dentist to go see Dr. Isaak and his beautiful, state-of- the-art office. His staff is very welcoming, and everything is explained to you. Dr. Isaak is an amazing person, and he took his time explaining everything to me. I’ve had a previous ‘bad’ experience with another orthodontist, so I was a little skeptical, but let me tell you… as soon as Dr. Isaak examined my teeth, he told me he was going to give me that perfect smile. I immediately felt I could trust him without even knowing him! I went in for a consultation and I walked out with braces, all done the same day with zero wait time. I would truly recommend Beyond Smiles to anyone in a heartbeat.”

Braces, Clear Aligners & Lingual Braces in Syosset

These are the most common type of braces, the ones you are likely familiar with, and the ones that are most easily recognizable. Brackets are low profile and are glued on the front surface of the teeth.

Aligners are removable and are fabricated out of clear custom made plastic. When worn in sequence, they result in gradual tooth movement to achieve desired results. Unlike Braces aligners are removable when eating or drinking.

Clear, transparent braces are brackets that also get bonded to the front surface of the teeth. These appliances provide higher esthetic appeal than traditional metal braces and can provide the same fantastic results within a short period of time.

Hidden braces are positioned behind the teeth, making them truly invisible. There is no need to remove them and with the invent of the modern techniques lingual braces allow for the fastest, most predictable movements.

The curvature of upper teeth should follow the curvature of the lower lip in a posed smile. This relationship is unique in all of the picturesque smiles.

The facial midline is a starting point of any smile design. In an optimal smile upper and lower front teeth should be aligned with the facial midline. When everything is aligned properly, harmony is created.

A broad smile arch eliminates the dark spaces between the upper teeth and corners of the lips, therefore creating a much more youthful, attractive smile.

Upper front teeth should be maximally displayed when smiling. Full teeth display provides the most aesthetically pleasing and youthful smile appearance.

The position of the teeth is one of the main reasons for seeking orthodontic care. The main focus of the treatment is not to “align” the teeth, but to find a unique balance between the art and science of orthodontics. Applying this balance will ensure the creation of a stunning, aesthetically pleasing smile.

An early orthodontic evaluation can help identify developing problems with tooth eruption, bite relationships, jaw growth, and available space. An evaluation does not necessarily mean your child needs treatment right away. In many cases, we simply monitor growth until the timing is right.
We look beyond whether the teeth are simply straight. Dr. Isaak Yelizar considers tooth position, bite relationships, jaw development, facial balance, smile aesthetics, and airway-related concerns when relevant. This allows treatment to be designed around the complete orthodontic problem rather than a single appliance.
Beyond Smiles offers traditional metal braces, clear ceramic braces, clear aligners, hidden orthodontic systems such as Brava and C5, MARPE, growth-focused treatment, and other advanced orthodontic techniques. The right option depends on your diagnosis, age, goals, and lifestyle.
Yes. When appropriate, our orthodontic evaluation considers factors such as jaw development, palate width, tongue space, bite relationships, and other structural concerns that may be relevant to breathing and airway health. When a concern requires care outside the scope of orthodontics, we may recommend evaluation or coordination with another healthcare provider.
No. Adults can successfully undergo orthodontic treatment as long as their teeth, gums, and supporting structures are healthy enough for treatment. We offer several discreet options for adults, including clear aligners, ceramic braces, and hidden orthodontics.
Orthodontic treatment costs vary depending on the complexity of your case, treatment length, appliance, and insurance benefits. After evaluating your needs, our team will provide a personalized estimate and explain your available payment options before treatment begins.
