As always the Big Smile Team was friendly and welcoming. I had not been here since before the COVID pandemic and it was good to know the team is still so nice. My hygienists was super friendly and gave the feeling she really enjoyed her work. Someone who hums and sings to the background music has to be happy with their work. Dr. Kim did a good job with a soft touch as always. I continue to come here even though they are not an in network provider and it cost me more more. The treatment and service is well worth the extra money paid.

I've been coming here a couple years now. I was always terrified of dentists and orthodontists starting young because of traumatizing braces experiences. My first visit, I got emotional and panicked with Dr. Kim and she gave me such patience and grace beyond what I deserved and has a bedside manner and empathy I wish everyone received when going in to take care of their teeth. I've been loyal ever since, and the care I receive here is the best and I've encountered.

It was my first time going here so I had a consultation and did X-rays. I can't believe how welcoming and professional this place is. What stood out to me the most is how they have you fill out a questionnaire to understand your overall health and to see if you have any conditions. They truly care about their patients! This will be my permanent dentist from now on.

I went here for work dental work because they were in my neighborhood. I even prepaid over $3,000. Long story short, -sloppy work. I almost bled to death. I ended up having to make an emergency visit to an Oral Surgeon. The head Dentist I believe his name was (Dr Siegel). did not even refund my money for that particular procedure. He blamed me. They took over $3,000 of my hard earned money and treated me like garbage.
I also had to have three fillings redone by an actual professional/-a Dentist who truly cared about what he/she was doing. The audacity of them to continue to send me emails. Do not get work done here. Unacceptable. Big Smile Dental was a BIG Mistake. All they seemed to care about was money. Unbelievable.

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.

Overall great experience. They were welcoming made sure to explain pricing for me since I don't have insurance. I like the Covid protocol. The doctor and staff were great! I don't like going to the dentist at all just from past experiences if I didn't have to get my fillings don't I probably wouldn't have gone but I'm happy I did, they were sweet and gentle made sure I was comfortable. I scheduled my next apt!

If only this place cared as much about your teeth as they do about billing! My experience with getting my crown was terrible from start to finish. First off the dentist's bedside manner - it was bad. I was so uncomfortable as she continually scolded her assistant while she had a drill in my mouth for an hour. When she was done I was so desperate to get away.
She should have advised a new mouth guard but instead just drilled it out to make room for the new tooth. With the numbing I couldn't feel my teeth to even confirm if it fit. Then for the proceeding months I lived with pain of a poorly fitting mouth guard. I tried to get them to look at it again but they would not make the appointment. Finally after a number of complaints they put me in with the owner who immediately accused me of not wearing my mouth guard which is why it didn't fit.
This was so frustrating when I was in so much pain from wearing it after the procedure. He drilled it out further and then had the nerve to bill me for a new mouth guard which I had to fight to get taken off. A year later I am now getting both the crown they did and another replaced because of the damage done by this poorly fitted mouth guard (it literally cracked the underlying tooth). They should be ashamed of this low quality of dentistry.

This was an alarmingly bad experience. I called ahead to ask if they do dental implants and they said they did. So hygienist was nice enough, then the dentist shows up and she's super abrupt and mean. I felt like she must have something better to do because she proceeded to look only at and X-ray my one tooth and she kind of rudely explains that the dental implant process doesn't start there?
How could I have known? She was also annoyed by how far my crown broke. Asking me how this happened (I was literally hit by a car), and why I let it keep breaking (simple answer: I'm poor) and why I thought the crown could be replaced (I didn't, not why I came in) Then I ask if she can check a back tooth that kind of hurt, she puts the camera on that one tooth and acts like it was like a dental horror show. "this didn't happen overnight, how did this get so bad." Don't get me wrong, it's a bad cavity, but I felt like she was trying to shame me.
What a dick. She then puts the image on a screen in front of me like "Look how bad this is" and I had to ask twice for her to take it down because she was straight up embarrassing me. Then she gives some half assed advice about brushing (fascinating- never considered brushing, asshole) when I said I couldn't afford to fill the cavity soon. I was billed for a full exam and told to go to someone else for the implants and then come back to them to finish it. NOPE NEVER RETURNING. HATED this experience. Literally scared to go to the dentist again. **they were also vague and weird about when I could put my mask back on

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!

After hearing "oh root canals are so painful!" Dr Kim did an awesome job and put me at ease. As i am rather skittish when it comes to medical procedures. She and her staff took really good care of me. All i felt was discomfort and very lil to no pain. She gave me options on what to do with a bad tooth which i appreciated. They fixed my tooth and i am beyond grateful and thankful. give them a try if you have teeth issues!

I used to be afraid of the dentist, when I came to this place they were so nice to me and they made me feel so comfortable that I don't feel pain anymore. For the first time in my life I can say that I love going to the dentist! They are super friendly and the place is very nice as well! I truly recommend them for any kind of procedures!

Everyone here is very pleasant and professional. The office is very clean and with covid-19 they take extra precautions to ensure a healthy space for patients. They even communicate prior to your appointment via text messaging what exact time to come in so that social distancing is in place. I've been coming here for more than a year and I'm always pleased with my routine exams and cleanings.
During my fillings today I almost felt as if I can fall asleep without any discomfort. Now if you feel as if you can sleep at a dentist office you know you're in the right place!

I have had my dental prosthesis done last year and I am really sorry that I have to say that I am not very happy with the results and that I am very disappointed and very dissatisfied! I have instructed my dentist that I wanted my prosthesis to be done by the dental technicians a certain way, but the female dentist insisted that she wanted functionality more than estheticis which I wanted first and foremost because I am the one wearing it, not her.
Upon more than two months of visit and appointments, I ended up setting the teeth myself to make them look better for esthetic's sake. But still, she refused to trim the gums and the palate to my liking so I would be able to speak properly and not make my gums look swollen in my face. After so many pleas, I didn't get what I wanted. I am so, so disappointed that I am not able to wear my dental prosthesis until now.
The funniest thing was, the dental office was so quick to charge me and I was the one who contacted my insurance to process my payments because apparently, the person in charge of processing the paperwork and calling my insurance wasn't doing her job properly! I was the one who called my insurance who told me that Big Smile Dental didn't call or contacted them!
What a bloody joke! No, I wouldn't recommend this dental clinic to someone who got the same case like me because I am not able to smile with a big smile like that of the name of their dental office because I look horrible with the teeth they made and promised to alter over time but I couldn't make further visits because I am very busy at work and have no car to travel often but order either Lyft or Uber just to get there!
And worst of all, I couldn't speak properly because of the very thick palate I was complaining about that they trim during my last visit so I wouldn't sound retarded to everyone I know at work. But they didn't! Instead, the dentist looked annoyed at me for telling her what I wanted to be done! I wouldn't even give a one or NO STAR rating for the services I received because I have no choice because my experience was really a big, big bloody joke! Not worth

I am so extremely disappointed in this dental office after having been a patient for some time. They are committing blatant insurance fraud and defrauding their patients as well. BEWARE of services you are told you may need and get a second opinion! My husband went in a few years ago and he was told he needed to have a deep cleaning. He agreed to the procedure and paid a hefty bill of what his insurance wouldn't cover.
After this, his following cleanings were normal and billed as such. Recently he went in for his usual cleaning and was told everything looked good. The technician proceeded to complete a standard cleaning. Shortly after we received an unusually high bill. My husband called his insurance and was told they had been billed for a deep cleaning. He let them know what must be an error because he did not receive that service.
When he called the office to have them correct the issue he was told legally in the state of Illinois once a deep cleaning is performed on a patient the must ALWAYS get a deep cleaning going forward. Ummmm seriously this is a law?!? You forever need to have a deep cleaning? Let's say that was in fact the case. he still was not given a deep cleaning they are charging for!
He has had periodontal cleanings in the past and knows what they are. What are they trying to pull here and how many other people are being over charged? Absolutely unethical! I will never give them another penny of my business.

Staff is very unprofessional. I used to go there years ago and stopped. I thought maybe things would be different. I called 3 times to verify they accepted my insurance and were part of the network. All 3 times they said yes. I finally scheduled a cleaning for my daughter. A few days later I receive a bill. I called and asked what it was for they said they are not not in my network. Very frustrating!

I was told over the phone that they would "work with me, " since they didn't take my insurance. When I arrived I received a 30 minute lecture from the dentist about how bad my insurance is and why I need to pay more for insurance. He also repeatedly insulted the way my teeth looked, probably in hopes of shaming me to go through with their overpriced procedures. I have never been talked to this way before in any healthcare situation. I DO NOT recommend!

When I first came here, I was hooked to the place. Been coming since. They are great about providing accommodations. I referred my entire family here. I read some other reviews. I agree that billing is the not their greatest strengths when it comes to communication. I remembered when I first came, I was surprised at some of the bills and blamed it on miscommunications.
That was solved and didn't happen again. Now they provide estimates before you leave if you want to consider for your next appointment. My dentist referred me to a specialist about a year ago. Today, I regret I didn't see one sooner because now I have a major toothache. What if that has something to do with it? What I don't understand is I just saw the dentist few weeks ago and they found nothing wrong on the x-ray or during exam to account for on-and-off pain.
I may have to go for second opinion because my pain have not ceased for five days now. All the hygienists there are great to my family! I think they are the best part of our visits. There are so many we keep losing track of their names but we do have a favorite or two who does a thorough job. Thank you!

I'm a fan. I never have to wait more than 5 minutes for my appointment. The hygienists are always thorough and pleasant. Unknowingly I had an outstanding balance from some fillings I needed that was over 90 days and they didn't hound me about it. They just told me to pay at my next appointment. They are fair and while my teeth aren't perfect, they use the wait and watch method rather than recommend a procedure right away. They've been my dentists for about 5 years now. I should've gave them props earlier.

I'm only giving them to stars because they are good dentist the reason that I dropped him down to just two stars is the fact that all these years I'm always getting a bill from them every time I see them even though I have dental insurance to find out that they never bothered to tell me that they're not in my dental plan and that's why I'm always paying so much.
I do like the care they provide but I feel that they should be more honest when it comes to Billings because I'm on a set income and I've been paying extraordinary fees to maintain good teeth to find out that this last year I've been spending a lot because of problems with my teeth which were hard to figure out considering I see a dentist every 3 months so it's time for me to find a new dentist and find dentist that use my plan which is a big-name plan anyway so I was surprised that they didn't take it

I've been going to this dentist since I had baby teeth. They always do a good job I always come in extra nervous and I feel silly after because i never feel any pain at all. I've had tons of cavities filled here and I got a root canal done today. I didn't even feel the numbing injections. They know what they're doing.
