We offer you teeth straightening solutions without everyone noticing your braces. The fantasy of "invisible" braces is now a reality with Invisalign/ Invisalign teen and hidden braces (Incognito). These are clear alternatives to braces. Invisalign are aligners that straighten your teeth without metal wires or brackets. They are removable clear aligners, which means they are virtually undetectable. Incognito are hidden braces, these are customized brackets that sit behind your teeth. No one will ever know you are wearing braces unless you tell them. Dr. Karin Grinbaum, who is a broad certified orthodontist in NYC, firmly believes that a contagious smile is the secret to every individual’s wellness. So, at Grinbaum orthodontics, we are determined to preserve and protect your precious smile.

Our patient’s journey with Aligners was both discreet and successful. Her misaligned bite was not only uncomfortable, but did not match her vision aesthetically.

We’re excited to have helped her achieve such a dazzling smile, thanks to our dedicated team! 🩵👏🥳
