INBRACE® is a convenient new treatment that improves your smile without anyone knowing. You'll start seeing visible results in just weeks!

InBrace® Hidden Braces


No wires or brackets, Invisalign® uses nearly invisible plastic, removable and comfortable aligners. They're a popular aesthetic choice for teens and adults.



Modern ceramic, clear or metal braces are smaller and much more aesthetic to what many adults remember. Teeth move faster and less painfully than in the past.

Kids & Teen Braces

Early Treatment

Correct dental problems at an early age. Make room for crowded teeth and reduce the need for future tooth removal. Improve facial symmetry by influencing jaw growth.

Early Treatment

Vaia T.

The emotions I feel writing this go beyond my expectations and honestly reality. I could never in a million years imagine how drastically Dr. Grinbaum and her team would change my life and perception.

Amitis O.

Not sure where to start - in addition to amazing care, a beautiful office, and wonderful staff, they truly go above and beyond to give their patients the best possible treatment and outcomes possible.

Ashley F.

Dr. Grinbaum is fantastic and so is her staff. Everyone is very professional, friendly, and makes going to the orthodontist enjoyable. My teeth look amazing, and Dr. Grinbaum was available and helpful throughout the entire process.

Ryan B.

Dr. Grinbaum was excellent in solving the problem my son had with his hidden canine. He had ingrowing teeth, and they were crooked. She patiently listened and understood our concerns, explained the options and answered all our questions.

Aslesha P.

I've just completed my nearly 2 year treatment with Dr. Grinbaum and I'm extremely impressed with the results I'm seeing! She is very professional, yet personable. Actually, her entire team is simply fabulous!

Kimball L.

Dr Grinbaum is amazing! I've been under her treatment plan for about 18 months. I'm 6 weeks away from finishing my treatment and I'm super stoked to get my retainers! I have incognito braces on the top and clear braces on the bottom.
