Invisalign® · Laura E.

After seeing several orthodontists for consultations, I almost gave up on correcting my smile. Then I met Dr. Grinbaum, who was referred to me by a co-worker. Her credentials were great and her professional manner was a relief. She reviewed the treatment options with me. I chose her treatment plan because I trusted her. I could not be happier with my decision. She was gentle, knowledgeable, proficient and straightforward. I can’t stop smiling!

Doctor’s Notes

Laura was nearly finished with her law degree and had many job interviews on the horizon. She wanted to launch her career with straight teeth. Visible braces were not an option, so she sought a discrete correction. Her choice was Invisalign® – clear plastic aligners that are removable for eating, and for interviews.

Chantal M. · Mother of two · Tongue-tie, laser

My son couldn’t latch for the first month. Days after Dr. Liel treated it, he nursed like he’d always known how.

In their words

For the first month of his life, my baby couldn’t breastfeed at all. Dr. Liel found the tongue-tie and released it with a laser, as gently as I can imagine — my son didn’t even cry. A few days later he was nursing with no trouble at all. It worked for my daughter too. I only wish we’d come sooner.

Incognito™ · Eric O.

Gaps in my teeth embarrassed me as an adult. When I was ready to fix the problem, I reached out to Dr. Grinbaum. It was such a pleasant experience. I was comfortable and at ease from our initial consultation. Dr. Grinbaum talked me through the process at every appointment. The office was welcoming and extremely accommodating with my unpredictable schedule. Thank you, Dr. Grinbaum!

Doctor’s Notes

Eric is a young professional in the financial sector. He was always concerned about his open bite — a gap between his upper and lower teeth. Eric felt insecure during client meetings and sought to correct his smile and bolster his confidence. He chose Incognito™ braces for a full bite correction without anyone knowing he was in treatment.

David R. · Father · Filling

A small filling that turned into a genuinely great morning.

In their words

I brought my son in for a small filling and braced myself for the usual struggle. There wasn’t one — no pain, no drama, just an easy, reassuring visit from start to finish. We drove home with a happy kid. We’ll be back for every check-up.

Clear Ceramic Braces · Naomi W.

As a new high school student, I was nervous about getting braces, since most of my friends had already had them in middle school. Dr. Grinbaum told me about clear ceramic braces, and she made the process super easy and very fast. She was always very kind, and she always took care of me by explaining what she was doing and why it was important. Dr. Grinbaum has been the best orthodontist and I’m sad I’m done having appointments with her, but without a doubt, I recommend her to everyone!

Doctor’s Notes

Naomi relocated from Ohio to NYC and enrolled in a new high school. She decided on clear ceramic braces to help her craft the perfect smile. It was exactly the confidence boost she was looking for in a challenging new environment.

Ceramic Braces · Fatima B.

I have never felt happier with my smile than I do now, and that’s all thanks to Dr. Grinbaum. I had a bad experience with braces before I met Dr. Grinbaum, but she made sure the process was painless and fast this time around. My braces were comfortable during the entire treatment. Everyone should have that feeling at the orthodontist! Choosing Dr. Grinbaum for my braces was the best decision, and I can’t stop smiling.

Doctor’s Notes

Fatima is a college business student who always wanted to fix the crowding of her front teeth, as well as a crossbite. A smile plays a major role in a first impression, Fatima believes, and she needed her smile to be its very best. She chose ceramic braces because they are more discrete than metal brackets.

Invisalign® · Harriet K.

Dr. Grinbaum is terrific. She is patient, and explains everything in detail, so you know what to expect during the entire process. No surprises is a good thing, and I am totally pleased with the results.

Doctor’s Notes

Harriet sought an esthetic orthodontic treatment to retract her teeth and close gaps. Her goal was to fix her teeth without making her many co-workers and friends aware of the process. For Harriet, Invisalign® was the perfect fit.

Incognito™ · Vaia P.

My treatment with Dr. Grinbaum exceeded my expectations. I was never comfortable with my smile because of my overcrowded teeth. But as an esthetician, I refused to get visible braces. Dr. Grinbaum introduced me to lingual braces, which changed my life forever. She was extremely helpful throughout this journey and treated me with the utmost respect. Now I receive compliments on my perfect smile all the time. Thank you so much!

Doctor’s Notes

An owner of a beauty and esthetic business, Vaia believes “the perfect smile” is absolutely essential. She had dental crowding to correct, but a treatment visible to her many clients was not an option. Vaia chose Incognito™ Lite, which are small hidden braces placed behind the teeth.
