“Excellent friendly, clean room clean staff sterilized places. this is my best dental clinic. I have to drive an hour from my house to the clinic. There are many dental clinics near my house, but I haven't seen any doctors with such a clean and professional attitude. I enjoy interacting with them.”

I had a wonderful experience at Smile More Dental during my appointment yesterday. The clinic has such a warm and calming ambiance—it immediately puts you at ease. My hygienist, Eizen, was absolutely amazing—gentle, thorough, and professional. He made the entire cleaning process smooth and comfortable. I also had the pleasure of meeting Dr. Daib, who was very kind, attentive, and informative. You can really tell the whole team cares about their patients. I left feeling well taken care of and genuinely impressed. Highly recommend this clinic to anyone looking for quality dental care in a relaxing environment!

Everyone in the office was extremely personable, friendly, and walked me through everything that was going on step-by-step. They worked with me to find the most effective way to use my insurance and when to schedule for follow ups, making the whole experience stress-free.
More than 1 year agoMason J.Verified patient
I would not recommend this office. The dentist is very rude, it took me over an hour to be seen, with an appointment! I did not even get my cleaning done that I went for because I needed a special cleaning and the doctor did not feel like staying any longer. So I basically went for over an hour to schedule another appointment.
June 25, 2020Sandra R.Verified patient

Dr.Diab and his staff was very pleasant and helpful, as for Dr.Diab, I loved the fact that he wasn’t judge mental due to me neglecting my oral health care. He was very Knowledgeable and understanding?? He came up with a treatment plan for me that fits my budget, and for that , I am grateful.
August 16, 2018Gwendolyn S.Verified patient
Dr Sami is very friendly and knowledgeable. He has a great bedside manner. The office is clean and comfortable. In front of each chair is a personal television that kept me distracted from the work being done. He is competent and works quickly. I highly recommend Dr Sami.
