Dr. Kosa is outstanding and so is his office staff. I had a chronically inflamed tooth that he treated with a root canal procedure. Although it very sore afterwards--in the normal range--after about 12 days it was finally pain free for the first time in a year. His office provided very attentive follow-up with me to ensure I was comfortable.

I recently had a root canal done by Dr. Kosa, and I can’t say enough good things about the experience. I’ve always been terrified of the dentist, but Dr. Kosa completely changed that for me. He was incredibly patient, knowledgeable, and kind, taking the time to explain every step of the procedure so I always knew what was happening. He constantly checked in on me, making sure I was comfortable and reassured throughout the entire appointment. What could have been a very stressful experience turned into one where I felt genuinely cared for and supported. I’m so grateful for his professionalism and compassion. Highly recommend Dr. Kosa, especially if you struggle with dental anxiety!

I needed an emergency root canal. Dr. David Kosa fit me into his busy schedule the same day that my dentist placed her call to his office. Dr. Kosa was great! He had the technique needed to effectively numb my pain. Throughout the work, Dr. Kosa explained everything he was doing. I was a little tender for a few days, but I was given appropriate medication, which allowed me to be reasonably comfortable through the healing process. I will not hesitate to recommend Dr. Kosa in the future. I feel fortunate to have been referred to him!

I have had 3 root canals done by Dr. Kosa and each has been 110% painless. In fact I listen to an audio book during the procedure while Dr. Kosa and his assistant work on my tooth. I have actually drifted off at times. Dr. Kosa is awesome he takes very good care of his patient.
