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

That patients become more knowledgeable about their oral healthcare. Patients are treated in the most respectful and honest manner, I like to feel that I have reduced their anxiety about oral surgery.

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

The ability to fully reconstruct a patient from ill-fitting dentures to the comfort, confidence, look and feel of real teeth with dental implants.

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

I love what I do each and every day. Making patients feel relaxed and comfortable is my goal.  The relationship we develop with our patients is so rewarding.  My least favorite aspect of dentistry is the dealings with the insurance companies to obtain medically necessary approvals for my patients. It is a constant battle to convince insurance companies to put the patient’s needs above their own.

Patient Review by Lisa F

On Tuesday 8/25/2020, my son had his wisdom teeth out in the hospital and Dr. First did the procedure. Prior to the procedure his staff helped me with forms and pre-certification at the hospital and then my son had a visit to go over the plans for pre and post op procedures. The office at Suffolk Oral Surgery in Smithtown was immaculate and all staff wore appropriate PPE so we felt protected from Covid-19. My son has a very complex medical history and allergies to medication. He is also Autistic and has Anxiety. The Staff and Dr. First did all they could to prepare us and answer all our questions. They also called to see how my son was after his surgery. All went well and I am grateful for our incredibly talented Oral Surgeon, Dr. Christopher First and his staff at Suffolk Oral Surgery, who helped make this a safe and smooth process every step of the way!!

Patient Review by Eileen P

Dr. First is an incredible oral surgeon ! I was very nervous about getting my wisdom teeth removed and his ENTIRE staff was more than understanding, making me feel completely at ease ! I had an incredible experience here with Dr. first, he made my wisdom teeth removal PAINLESS !!! I had no swelling after the surgery, and such minimal pain after, Advil was more then enough to take care of any discomfort. It’s been a week since I’ve had my wisdom teeth removed and the healing process is going great all thanks to Dr. First and his staff ! I highly recommend this office, if there was an option for 100 stars that’s what my rating would have been. A HUGE thank you to everyone at this office for making my experience so quick and easy, you guys are the absolute best !
