After moving to Chicago, I couldn’t find a reliable, honest dentist. That is until I found Big Smile Dental. Dr. Kim is amazing and provides a great experience. She is caring, attentive, and excellent at her craft. The dental hygienists are thorough but gentle with my sensitivities. The staff is courtesy and professional. Highly recommend!

I have been coming here since 2007. Dr. Siegel installed my braces in 2007 until 2010 I was hard headed and didn’t always listen to his instructions so I had to wear them an extra 10 months. The environment at Big Smile is always welcoming and caring. The staff and doctors really care. If you are looking for a dentist look no further. Call them asap to make an appointment. No to mention I haven’t been to his office 2014 it’s now 2021 I still had a balance of 300.00 they didn’t say well you have to pay your balance 1st before you will be serviced. I paid my balance I love this place. Everyone at Big Smile continue doing what yall are doing its working. And Thanks again.
