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 relationships 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 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 !

Patient Review by Richard D

This is a terrific practice. Everyone is personable and helpful. Explanations by both doctor and staff are thorough and offered without prompting. The people at Suffolk Oral Surgery make tolerable what is by its very nature an unpleasant experience. What more need be said?

Patient Review by Christie R

Dr. Jamdar was wonderful. I had a lot of anxiety going into the office for my dental implant surgery, but his confidence and calm demeanor put me at ease. The procedure wasn't half as bad as I thought it would be! Pain was minimal the few days following. He really is great at what he does. His surgical assistants were amazing as well. Very compassionate. They turned an unpleasant situation into a positive one. I will definitely recommend this office to my family and friends.

Patient Review by Linda R

I almost never write reviews, but felt compelled to in this instance. I highly recommend this oral surgery practice. Dr. Guariglia & his assistant (can't remember her name, but she is engaged) were absolutely wonderful! They eased my mind, calmed my nerves, made excellent recommendations (sweet air), & generally made my extraction as painless as possible. TY!

Patient Review by Alexander M

Any fears or worries I felt before the dental implant procedure were immediately dismissed as I was made physically and mentally at ease. I was always in the best professional hands I had a painless experience both during and on the days afterwards.I cannot believe that I waited so long to have the surgery when it was such a seamless operation
