Gabriel Sim, DDS

This doctor is the epitome of professionalism and class. He takes the time to give the patient a thorough explanation of the impending work. Then, he does the best work possible. I had a root canal procedure. Let me just say that the work he did erased all the hearsay I’ve ever had about root canals. The only bad news about Dr. Sim is that he works soley with Endodontic procedures. I could only wish he performed a full range of Dentistry and the world would be a much happier place.

TOTALLY PAINLESS! Gentle dentist. Calming voice. Explained everything. Couldn’t have been a better experience. Highly recommended.

Having a wisdom tooth suddenly go very bad late on a Friday afternoon made for an amazingly painful weekend. My dentist provided some temporary help, and recommended seeing Dr. Sim, who was able to see me first thing Monday morning — which at the time merited a 5 star review alone. But he also handled the root canal extremely well. Incredibly clear explanation of what was going to happen, and what he found and the treatment procedure. Everything worked out perfectly and he inspired confidence in the process.

A few years ago my regular dentist told me that I had two teeth dying of resorption.
This led me on a journey to fix my teeth. What I found was a long list of mostly scary, unscrupulous, unfriendly and greedy dentists in the city of Chicago and suburbs.
I even came across one dentist who was operating without a license (his boss was on the list of top ten dentists in Chicago Magazine) and one dentist who referred me to his associate whose license had been revoked for five years for drug charges.
I did come across a small handful of decent, skilled honest dentists and Dr. Sim is one of those excellent dentists.
Dr. Sim looked at my teeth and he was very honest with me.
He told me my two teeth were in very bad shape and he thought that the root canal would fail within a year. He suggested I pursue implants which I am currently doing.
Dr. Sim was honest with me, he did not waste my time or money on a procedure that would fail. He gave up income by being honest with me and I find that most Chicago dentists would not do that.
Finally, Dr. Sim and his assistant Renata were very pleasant to deal with and fees were easy to understand.
If I need a root canal in the future, I’m going to Dr. Sim.

Wow. Dr. Sim is an example of how every doctor should be. Thorough and informative, friendly, articulate and extremely approachable. When I walked out of my consultation appointment, I felt informed and armed with the knowledge I needed to make the decisions I had before me. He seemed genuinely seemed concerned with my well beong and even counselled me on a second opinion and gave me his perspective on what he would do if he were in my position. Regardless of my issue, I walked out of that appointment with a genuine smile on my face!

Root canals suck, but Dr. Sim is wonderful. This doctor is informative and personable, and has a gentle and efficient chair side manner. My initial procedure was fast and pain free. His staff is efficient and friendly. I’m very happy Modern Dental referred me to him, and would recommend Dr. Sim to a friend without hesitation.

Horrible Infected Tooth, went nuclear in terms of pain, and Dr. Sim took my emergency call on a Sunday and got me in for an emergency visit on Monday. Better than just cleaning out the infection and getting rid of the pain, Dr. Sim spent the time to talk to me about a Plan A and a Plan B going forward with the tooth, the costs and the potential short term/​long term outcomes. He also called me back twice that day (the 2^nd time after 7:00pm) to see if I had any residual pain and told me he planned to contact my dentist about this problem tooth. Thorough consult. Depth of options. Follow-​through, follow-​through and more follow-​through. I’ve had five root canals by five different people. No more. I am forever with Dr. Gabe Sim.

Who the hell leaves the endodontist with a smile on their face after a root canal? Me, apparently.
The entire staff is incredibly friendly and professional. Dr. Sim is very straightforward about how the procedure will go, and told me about common issues that might come up and how he would deal with them if they came up. He was very calming and made me feel reassured about the procedure itself. It wasn’t very painful at all (and the novocaine shots, which are normally the worst part, were a breeze)! After the procedure, he gave me a detailed description of how it went, and what the next steps were (how sore I might be, what pain medications to take, etc.).
The next day, he called me from his personal cell phone (it was a Saturday) to check up on how I was feeling.
Hands down, the most enjoyable dental procedure I’ve ever had. Let me reiterate: a ROOT CANAL PROCEDURE was the most enjoyable dental procedure I’ve ever had.
Bonus tip: Ask him about anything regarding the anatomy/​physiology of teeth. The man is a genius!

Amazing Doctor and staff! I had an emergency root canal and I could not have asked for better treatment and service from Dr. Sim. He took the time to explain each situation and was right on top of everything. I would recommend Dr. Sim and his staff to anyone in need of a good endodontist!

No one wants to visit the endodontist so the fact that I’m (along with many other Unilocalers) am giving Dr Sims a 5 star rating must mean he’s pretty awesome. 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.

Dr. Sim is great!
I went to Dr. Sim to fix my failed root canal. He took to the time to explain the situation in easy to understand terms and lay out my options. He did a wonderful job fixing it. My standard dentist commented on his excellent work. I am very happy with the results, the office friendliness and Dr. Sim’s expertise.
Highly recommend. Also, love that he has 7am appointments so us working folks can flex it into our schedule.

Brilliant! I recently had a a root canal done here. His work was flawless and Dr. Sim phone a couple times over the next couple weeks to make sure everything was okay. Nice man and very professional!

I had a root canal last Fall and I meant to post a review right away but time got the better of my good intentions. But better late than…
Before my procedure started, Dr. Sim took the time to explain what was going to happen. I was in a lot of pain and leery of more but his calm, thoughtful and professional manner helped ease my worries and fear. When you think about it, opening your mouth to someone to poke around in is not an easy thing to do. But he took his time and made the whole thing as pain free as it could be and I didn’t have much discomfort at all.
I heart Dr. Sim. He is my favorite Endodontist and those words strung together have never been written by me. Ever. Thank you Dr. Sim for your excellent care.

Dr. Sim is top notch. Expensive, but top notch. I came to him to have a root canal retreatment. It seems that my root canal from 10 or 11 years back had a recurrent or ongoing infection that nobody had noticed in all that time because none of my dental x-​rays were down to the root. Of course, since I had no nerve in the tooth it was painless to me and I would never have known. I searched Unilocal for a well regarded endodontist and found Dr. Sim.
During my consultation, Dr. Sim took some X-​rays and went over all of the options. He was very, very thorough. I decided to go with the somewhat conservative option of retreatment (the more conservative option being ignore it and hope for the best). The retreatment is in two parts. He goes in the first time cleans everything out, makes sure there is nothing going on that wouldn’t show up on an X-​ray like a fine crack or unnoticed root branch, fills the tooth with a temp filling, and gives you a prescription for pain. The pain was not bad, although, as promised by Dr. Sim, it did hit the third day. It was much more a sense of discomfort than pain. He called to check up on me the next day, too. very nice. Two to 3 weeks later you return and he cleans out the tooth again. Assuming everything has gone well, he’ll send you off to your regular dentist to get a filling in your crown.
Everything was very easy and not scary. The only thing I would change would be the Novacaine shot. His was not the most gentle I’ve ever experienced, but since everything else went so well and he’s so nice I’m prepared to let it slide. Another bonus am going to Dr. Sims is the very lovely, kind, and patient Renita at the front desk. She is super nice when you are a super annoying patient like I am. Dr. Sim is lucky to have her.

I had my root canal done here. I’ve heard a lot about the procedure beforehand, but I never expected it to be so painless. Dr. Sim was very nice, professional, informative and, above all, a great listener. He answered all my questions and accommodated me in every way. The procedure itself was over long before I expected. This was my first dental visit of any sort during which I experienced absolutely zero pain.
Even my prescription for pain meds didn’t have to be used. I had no residual aches or swelling once the Novocaine wore off. All the staff was friendly and the office was clean and well maintained. Truly a 5 star experience as far as dental work is concerned.

Top notch. Modern, professional, instant digital x-​rays. If you give a failed root canal another chance, this is the place to go. Ultra smooth procedures, I took a nap!
You will know exactly what he is going to do and how much it’s going to cost, no hidden fees. Retreatment of root canal (with new crown), so far so good. Saved me a bunch by avoiding an implant and getting more miles out of my tooth. Remember, most insurances don’t pay for implants and saving your tooth should be the first choice. Highly recommended.

I was referred to Dr. Sim through my general dentist to get my first root canal. I was anxious about the procedure, but Dr. Sim was very thorough and informative of my options. He was calm and gave me a play-​by-​play throughout the whole procedure. It was also quick! Finished in less than an hour! I didn’t even need to take the pain medication he prescribed after the numb feeling went away from the procedure. I highly recommend Dr. Sim. =)

When I went to Dr. Sim, I must have had at least 5 root canals that needed to be done.
I have Seizures that made my Jaw lock for hours, and unfortunately broke a lot of my teeth so bad they needed root canals. So if you have seizures and are looking for someone who can handle that, this is the man to go see.
I was deathly afraid of any injections to make my mouth numb before working on them, because when the last dentist did it, my jaw locked and the seizures came.
However with Dr. Sim, he was very understanding and caring regarding my seizures and was more than willing to take on the challenge.
He is exceptionally honest, trustworthy, patient, understanding and caring, professional and his pricing isn’t bad either.
I would defiantly HIGHLY recommend Dr. Sim.
Thank you for everything Dr. Sim!!!

Needed a root-​canal
In and out in less than 50 minutes… wow that was fast, easy and painless.

Dr. Sim is not only a great dentist, but a highly ethical one. Call me a cynic, but dentistry and ethics are two words that I usually hesitate to include in the same sentence.
(DISCLAIMER: I know that there are plenty of highly ethical dentists, but I’ve had so many try to fleece me over the years, that I tend to be more skeptical than most. Please don’t think less of me for my one prejudice.)
I went to Dr. Sim because I had a root canal that failed and needed to be retreated. At the outset, Dr. Sim was very honest with me when he told me that a retreatment had a ⁵⁰⁄₅₀ chance of being successful. I figured I’d roll the dice and see what would happen. He did the work and told me that we’d wait and see.
Fast forward two weeks.. . I went in to do the follow up and Dr. Sim determined that the re-​treatment wasn’t going to work and that I would need to get an extraction. I was disappointed, but I appreciated him being honest.
BRACE YOURSELVES, here comes the shocking part.. . HE REFUNDED ME MY COPAYMENT! I thought he was kidding when he told me that he was going to do that, but he told me he didn’t feel right taking my money if his work wasn’t going to hold up.. . I’m still in shock.. . it’s good shock.. .but shock nevertheless.. .
So.. .right now.. .I have to go back to my regular dentist (Dr. Shimoda see my positive review of him) to discuss my options. Though the thought of losing a tooth makes me sad, the fact that I was treated so kindly by an honest dentist, definitely softens the blow.
