Dr. John Guariglia - Oral Surgeon at Suffolk Oral Surgery Associates, LLPJohn Guariglia, DDS is a Diplomat of the American Board of Oral and Maxillofacial Surgery and is experienced in the full scope of Oral and Maxillofacial Surgery. He completed a Residency in General Dentistry and Oral and Maxillofacial Surgery (both in Kings County Hospital), and a Fellowship in Oral and Maxillofacial Surgery at Missouri Baptist Medical Center.

In addition to private practice, Dr. Guariglia is actively involved in continuing education, the Suffolk County Dental Society, and cub scouting (Cub Master of Pack 163). He also maintains a teaching position at Kings County Hospital.

What is your philosophy of dentistry? How do you want patients to feel when they leave your office?

Dentistry is the one field of medicine where diseases are treated, function is restored, and beauty, as well as self-esteem, is improved. I want patients to feel as though they received the best, most current treatment available.

What do patients get from your practice that they wouldn’t get somewhere else?

Patients are treated by a group of caring professionals who understand their needs and fears. One of our doctors is available 24 hours a day for post-operative emergencies. For difficult cases, they get the combined experience of Five Oral and Maxillofacial Surgeons.

What do you like most about dentistry? What do you like least?

I love the ability to totally change a person just by restoring their ability to eat/chew in an esthetically pleasing way which increases their self-confidence. My least favorite aspect of dentistry is dealing with insurance companies.
