    Ora Dental South Loop's team is the best of the best in every service & department. I first found them for an implant procedure that other oral surgeons had assured me wasn't possible; Dr. Koos made it happen and my results were beautiful. I've seen Dr. Kralj for years since then, and despite moving away and changing jobs twice since becoming a patient, I always make the trip because they're worth it. Their techs are all wonderful -- they stay ahead of industry trends with the latest pain- and inconvenience-limiting tech, and just recently, went above and beyond to hand-paint a temporary crown for a better color match plus rushing my replacement appointment to finish up before an upcoming wedding. Their front desk team is unbeatable -- Ashley routinely puts in extra time and energy to go to bat for us to make sure our insurance pays out the absolute most. She even helped us resolve a billing issue with another service provider that we'd been referred out to for a root canal. The office is calm and lovely, the TVs in the exam rooms and the waiting room are usually playing HGTV -- I genuinely look forward to my visits here. I've had a LOT of dental work in my life so have many points of comparison. This office is beyond the best. I constantly recommend them to everyone I know and feel like my luck in finding this team has genuinely improved my life.

    I'm response to you, Dr. Koos, I love how you were able respond to my Yelp review but can't take the time to respond to my emails nor phone calls. And you were so quick to outline the details in this "consent form" I supposedly signed, but can't furnish it along with my medical record. There was NEVER a discussion that took place that this issue I wound up with, would've been the end result as you claim. You even had a discussion with my current orthodontist about how things could've resulted differently. But you probably don't recall that either? Hmm..? Instead of taking responsibility for your wrong doing, you keep pointing fingers at other reasons to excuse you from fault. This is completely unacceptable. It's been over a year AND I'M STILL WAITING TO RECEIVE MY MEDICAL RECORD. If that's not admitting guilt, I'm not sure what else it could be? Where do I even begin? I was referred to Dr Koos for a simple upper impacted canine extraction. The procedure should have been straight forward but unfortunately resulted in a significant defect that Dr Koos failed to acknowledge during the initial post treatment visit. Since the incident, I have spent over $7k in treatment and still have approx $26k left to go! When I woke up from the extraction, Dr Koos placed a mangled splint to support my teeth from falling out. This was the first of many issues to come. After weeks of healing I noticed a huge chunk of my gum/bone missing. He claimed this was "normal" and was healing perfect. I listened to my gut and sought out a periodontist along with a prosthodontist both of which stated something was wrong and they could not fix this without additional surgeries. I then revisited Dr Koos after I demanded a refund. (He agreed to refund me) because of the "undesirable" results. And of course at that point did he finally acknowledge the defect. This is only the beginning of the trouble I have gone through with this practice. I've still not received my refund. I also have requested help to pay (a small portion at that) for the damage Dr Koos has caused BUT he still has yet to respond. Not only that, he and his office has yet to release my medical record that I've requested on several occasions. I unfortunately have had to move forward with a lawyer but if this review can help one person-please please please do your research!!! This review might not last long on here and they pay to have negative reviews r

    Guess I'm not having my spot that I rescheduled at the end of April and no one told me was cancelled

    I have an appointment in two weeks and know one has reached out to me about rescheduling. I'm supposed to finish my set for Invisalign's and now I have a chipped tooth. I keep calling but know one is answering so I guess my question is are they open?

I'd like to give Dr Sims a billion stars just for telling me I don't need a root canal, which I thought may be necessary to get rid of my frequent headaches. However, he deserves a zillion stars for the time he spent with me trying to figure out the cause of my headaches. After taking a look at my teeth and quizzing me about what's going on in my life right now Dr Sims mentioned that I may just be grinding my teeth in my sleep. He told me what kind of disposable nightguards to buy on amazon and even took the time to tell me which packet on amazon is the most affordable. His office also followed up 2 weeks later, just as they had promised, to see if the nightguards were helping at all. For those concerned (thanks)...they are! While Dr Sims was my favorite of the few people I met in his office, his assistant gets kudos for being patient while trying to xray what may be the smallest human mouth ever (or so I"ve been told by my dentist's office). Parking in this area can be a pain, but the building does have a valet parking option. I hope I don't ever need a root canal, but if it happened at least I'd feel comfortable going back to Dr Sims! Just make sure you're calling the correct Dr Sims since there's another dentist by the same name on Clark street. .

I've never left here in pain after a root canal, not even had to take medication after which is probably partly my own pain threshold but also I think speaks to his skill. He's got a great bedside manner, is very communicative, and his staff is great too. I'd absolutely recommend his practice.
