While attending Penn, Dr. Dayan received the Rabinowitz Memorial Award in Biochemistry, an honor bestowed upon one student from each graduating class.

Dr. Dayan's excellence at Penn was reaffirmed by his acceptance into the elite orthodontics program at the University at Buffalo immediately upon graduating from dental school.

He obtained a dual degree of Master of Science in Orthodontics and a Certificate of Advanced Study in Orthodontics by researching, submitting, and defending a written thesis. The program is highly selective, accepting only four applicants from the United States annually.

Outside of the Office

Dr. Dayan loves greeting patients by name, playing video games and sports with his boys, trying new foods and ice-cold drinks, and seeing his patients in Brooklyn.

Dr. Dayan loves living near his practice and can't wait to meet you. He's happily married to his wife, and they have four amazing sons.

Braces-Friendly Recipes

Finding delicious recipes that gel with your braces can get a little sticky.

But just because you’re working hard on your new smile doesn’t mean you need to completely change your diet — or that you have to deny your taste buds a sweet treat.

That’s why Dr. Dayan has collected some of his flavor-ite braces-friendly recipes in one spot.

They’re a blast to make as a family or with friends — and with all the hard work you’re doing during your braces treatment, you deserve a cookie, shake, brownie, or whatever delicious snack you’re craving.

Jam With Dr. Dayan

Do you ever wonder what keeps Dr. Dayan grinning during your appointment? Helping you get the smile of your dreams, of course — and listening to some awesome tunes in the process.

Now you can tune in to his Spotify playlist and jam along with Dr. Dayan between your appointments.

Because there ain’t no mountain high enough — or malocclusion complex enough — that One Love Orthodontics (and some good songs) can’t fix.
