Dr. Louis J. Buono's advanced technology, extensive education, and superior skill have made him a favorite dentist in the area. 

If you want treatment from a compassionate pillar of the Long Island, NY, community, look no further. 

What Sets Dr. Buono Apart

Extensive Education

Dr. Buono graduated from the New York University College of Dentistry in 1987. He began practicing the arts of cosmetic and family dentistry in Garden City Long Island the following year. Throughout his career, he has completed continuing education to improve his advanced skills and maintain membership in prestigious organizations. His training includes the Aesthetic Advantage program with the world-renowned cosmetic dentist Dr. Larry Rosenthal, and extensive study at the Dawson Center for Advanced Dental Study in Tampa, Florida.

Top-Notch Technology

Garden City Smiles was the first dental practice ever to implement the Cadent iTero 3D Scanner. This advanced handheld device allows for incredibly detailed imaging, and eliminates the need for intrusive dental options like gels and putties. Following great results with the original, Dr. Buono recently adopted the upgraded iTero Element. Another example of our excellent technology is our digital X-rays, which reduce patient wait time, allow for a better understanding of their dental care, and use the lowest amount of radiation possible. 


For decades, Dr. Buono has fine-tuned his personal dental philosophy. Frustrated by hearing stories of patients being treated as paychecks by other dentists, he decided to fashion an all-encompassing approach to dentistry. The core belief animating his philosophy is that mind, body, and spirit are all crucial to good health. Dr. Buono strives to create a truly calming and soothing atmosphere while providing a spectrum of cosmetic and restorative dentistry treatments. He treats patients like people and truly cares about all aspects of their experience.

I tried many different dentists prior to making an appointment with Dr. Buono who was in the office next door to my prior job. I could not be more happy that I decided to make that appointment and highly recommend him and his staff to anyone looking for a dentist. This is a dentist you can trust. His staff are always friendly and upbeat - you will never leave his office disappointed.

Dr. Buono is the best! His office and staff are amazing. Their attention to detail is like no other and they always make me feel comfortable. I have always been squeamish and hated the dentist until I started coming to this office. Dr. Bueno did my veneers 3 years ago and has been maintaining them ever since. They came out amazing and it’s the best decision I’ve ever made. Love my smile!

Who Is Dr. Buono Outside the Office? A Long Island Family Man

When he's not changing patients' smiles and lives, Dr. Buono enjoys spending as much time as possible with his four children. He has brought his passion for sports to coaching them and other children in baseball, basketball, football, and soccer. Of course, since Dr. Buono has been practicing dentistry in Long Island for over 30 years, he often sees his patients at his kids' sporting events. It gives him great pride to see his patients flash the smiles he helped create.
