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.

Patient Review by Michael S

My son had all four impacted wisdom teeth out over winter break. Dr First said it was his most difficult case this month. My son had no swelling and minimal pain even though Dr. First said he would be sore. The front desk and assistants very friendly too. I would highly recommend this practice.

Patient Review by Melissa R

My son had all 4 wisdom teeth pulled by Dr. First and he was amazing made my son and I feel so welcome and comfortable and walked us through step by step before and after the procedure. The staff went above and beyond assisting me from day 1 and over the next few days on what to do and what to expect. Now I see the reasons why my dentist recommended Suffolk Oral Surgery Associates. They treat you like family! I would recommend anyone who needs oral surgery to go here it was a real pleasure. I would give more than 5 stars ⭐️ ⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️
