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 Rick G

Firstly, l suffer from extreme dental anxiety and have since my childhood during the primitive era of dentistry in the 1950s and 60s. I needed to have a molar and the wisdom tooth behind it extracted and my regular dentist, who is great, sent me to Dr. Guariglia. He did a great, pain free, incredibly skilled job of extracting the teeth and doing a bone graft for a future implant. There was virtually no post-operative pain or swelling and though I had the prescription for painkillers filled, I did not need them. I didn’t even need Tylenol or an NSAID. There was only minor bleeding afterwards but it only lasted a few hours. Given the level of anxiety that I experienced beforehand, I realized the worry was totally unwarranted. I give my highest praise and recommendation to Dr. Guariglia and his excellent staff. Dentistry and dental surgery have advanced light years since my childhood. It couldn’t have been a better experience.

Patient Review by Kristin S

I cannot say enough positive things about Dr. Mundiya and the incredible team. Like many, I was extremely anxious and nervous about my tooth extraction. Jessica was an angel and held my hand. I had a a decaying wisdom removed. From the moment I walked into the office, the staff made me feel completely at ease. They were kind, patient, and took the time to explain every step of the process, answering all my questions thoroughly. The office environment was calm and welcoming. I wholeheartedly recommend Dr. Mundiya to anyone in need of oral surgery, especially if you have dental anxiety. They have changed my perception of dental procedures and I am so grateful for the exceptional care I received. Thank you for everything!

Patient Review by Jacqueline A

Such a great experience with Dr. First and this oral surgery team! My 10 year old was nervous, but everyone made him feel so comfortable. Ms. Sandy and the other assistants were absolute angels so patient, sweet, and amazing. And Dr. First himself? Super knowledgeable, took his time explaining everything, and had my son laughing before he even sat in the chair. We even forgive him for being an Islanders fan 🧡 Truly a wonderful group who cares about their patients. Highly recommend if you’re looking for a friendly and skilled oral surgery office!
