About Your Dentist

Isam Estwani, DDS, FICOI

In Dental School, you learn about teeth. In life, you learn about people. Put them together, you get a Dentist.The joy of Dentistry is that you are always being enriched by getting up close and working with all different kinds of people, and no one person is the same as another. I believe this is why what I do is called the Practice of Dentistry. I believe that our mouth is the gateway to our body, and our body is the gateway to our spirit.

My Mission

My mission is to assist my patients in maintaining a healthy, comfortable mouth for a lifetime. I want my patients to feel in control of their oral health while enjoying a healthy, beautiful smile. Giving my patients a comfortable and pain-free dental experience is my priority. The trust my patients put in me is a great honor that I dont take lightly.
