Dr. Patel and Lesli did a fantastic job removing two of my tooth, I was completely numbed and did not feel a thing. I’m super happy and satisfied with how the procedure went and would highly recommend coming to definitive dental for all dental work.

Had to go in for an emergency fill. From my appointment to having my benefits verified everyone was great.
I was glad they could see me very quick. I ended up needing two fillings and where done the same day. Dr. Patel definitely did her best to save my tooth that was bothering me for a couple of weeks. Leslie was really great! Thank you all for everything!

I’ve used Dr Guirguiss since Dr Cherry retired, and have been very happy with him. I have referred my mom, fiancé, his dad and several of my friends who are fellow members of the Chamber of Commerce.

I’ve spent the last 12 years trying to find a good dentist and I FINALLY found him!! For some reason, dentists have struggled to get my mouth numb. I was convinced that the anesthesia just didn’t work for me anymore and I suffered so much! After Dr. Guirguis gave me the anesthesia, I gripped the arm rests and braced myself for the pain. To my… amazement, I didn’t feel any pain at all, whatsoever. For the first time in a long time, I could relax in my seat without pain. Dr. Guirguis is a very talented and skilled dentist. I appreciated the time that he spent to show me on
