What Our Patients Say About Us

My experience at happy smiles dental was very good. There is a very friendly atmosphere here that definitely makes it less stressful than it already is to go to the dentist. I got all of my wisdom teeth removed here and all of the surgeries were completely successful! I am happy that I got it done at happy smiles dental.
Dr. H is amazing! The entire staff is friendly and professional. I highly recommend Dr. H for dentistry and extraordinary filler and facial serums- my skin and smile look so good!”

Happy Smiles is a great practice. Everyone there is courteous, they listen, they’re inviting, and the doctors and assistants are all very professional and thorough with everything they do. I haven’t been to the dentist in such a long time, mainly because I just hated going and it was such an inconvenience. These people make it easy and, dare I say, almost enjoyable! Great job!

I am so pleased and I feel confident in the care I receive here at Happy Smiles in Ijamsville/Hyatt Center. I have needed to have several different procedures on top of having anxiety about dental settings… and I cannot believe how easy and practically painless it has been to come to this one practice for expert treatment!I am always cared for with gentle compassion by all staff. They all support each other as a truly effective team, and Dr. H is super- knowledgeable and experienced.Such a very friendly practice!I highly recommend them.

This was my first time here at Happy Smiles. Overall a great experience. The front staff was pleasant and welcoming. Dr. Nasr was very friendly, knowledgeable and patient while explaining the x-rays to me. I also noticed the assistant cleaning the room next to mine after use. The only reason I gave it a four was the lack of privacy for each patient. Given the layout, the "rooms" are connected with very little privacy. Maybe a curtain could help. I just moved here and would really like to have my husband and my son join the practice, especially since it's a super convenient location and the staff are very friendly and more than willing to welcome you. Thank you for a pleasant experience.
