I came in for a minor bonded retainer smoothing after my former orthodontist doubled their out-of-pocket fee for the same service. Dr. Mark Jacobs took care of it efficiently and even removed plaque around the retainer without charging extra. He saved me money, was kind and professional, and made a great first impression. If my job situation changes in the future I'd be happy to become a regular patient! EDIT 3/19/26 - Visited Dr. Jacobs again but this time for a cavity filling on a bottom-front tooth. Service was as superb as the last! read more

I highly recommend this Doctor ! I can't say enough of good things about, staff is amazing! Every single person there takes care of you on a very next level! I have been going to Dr Jacob's for many years now and never disappointed! I have a lot of anxieties, but always feel so comfortable with this staff! , thank you for reading this review! I never write reviews, only when I feel confident! read more

When I moved to the Deerfield area a few years ago, I originally planned on seeing my previous dentist, even though it would have been a substantial drive. My dentist retired right after I moved, so that option was out. After reading reviews, I came to Dr. Mark Jacob. I hope he never retires! The entire team that you will interact with, from Kathy the manager, to Sandra (shout out to my favorite hygienist!), Ruben, and of course, Dr Mark himself; everyone is spot on, professional, and simply wonderful. I love going to dental visits now. read more

Dr. Jacob is the best dentist! He is detail oriented, an amazing teacher, kind, timely, and the best at his craft. I would travel across the world to specifically see Dr. Jacob because I trust him and know I'll leave with a smile. I recommend his practice to everyone. His staff - Kathy, Ruben, Sandra, and more are just as incredible as Dr. Jacob. I wish I could nominate everyone for an award, but this will have to be a start. Thank you everyone at the office for your many years of support and care! read more

Dr. Mark is an exceptional dentist with golden hands. He cares about each of his patients. He recommended an oral surgeon to do a root canal. The surgeon was excellent. Dr. Mark texted me after the root canal for a week to make sure I was healing well. Dr.Mark is the best! read more

Dr.Jacob is unethical, dishonest dentist and has the worst dental practice. Not only he and his team do not care about his loyal clients, he does not have any compasion or communication skills. He should be ashamed of himself of what he put me trough. I was extremly stressed out, lost sleep and had anxiety over it. Recently he did some dental work, it was wrong on his part. I told him I'm not happy with it and it needs to be redone. First, he totally ignored me: would not answer the phone, would not return my messages. Then, he was "holding me hostage" by saying he's ONLY going to fix his admitted mistake, if I'll do more dental work for other tooth for additional fee. I would strongly advise anybody who'll consider going to his practice, be careful and think twice! read more

Dr. Jacob is a tremendously talented DDS. He and his staff are very professional and friendly. He has guided me through years of a difficult challenging dental situation. He saved and repaired teeth for many years and I'm sure extended the life of my teeth for many years. When the time came for a whole mouth dental implant he guided me through the whole process and walked every step of the way with me. I couldn't be more proud and happy with my new beautiful smile. I receive compliments everyday and now enjoy smiling again read more

Dr. Jacob changed everything for me. I left my lifelong dentist because I wasn't happy with her. In the matter of 2 years, my teeth are in the best shape that they have every been. The periodontist did a gum graft for me, which turned out great as well. One of the things that had bothered me was that I had a gap between my teeth. I had tried doing Invisalign, but I'm bad at keeping with it. Dr. Jacobs came up with a genius idea that fixed my teeth in ONE HOUR. He used filling in between my teeth and they look great. It has lasted 1.5yr so far with no sign of needing to do anything right now. It is amazing. I now smile with my mouth open. I highly recommend Dr. Marc Jacob and his staff. read more

Mark W Jacob, DDS - Periodontists Near Me - Deerfield, Illinois

Dr. Jacob and staff seem thorough. But while Dr. Jacob's name is on the door, the procedures are now actually done by a younger, less-experienced but nice Dr. Lorenzo. But last time I was there for a procedure, Dr. Lorenzo left me halfway through to serve another patient for 15 minutes while I sat alone waiting with a big hole in my tooth. Unprofessional. Do not let Dr. Jacob do any tooth extractions! Long story short, have an oral surgeon do extractions. I suffered a horrible experience having a failed tooth extraction happen there. There was a prior scheduling mishap: I showed up and my appointment cancelled or moved without notice. Time to find a new dentist. read more

Dr. Jacob is awesome. After my primary dentist went into partial retirement, he is now my go-to dentist. His staff is very professional and kind. His office is pristine, modern, and spacious. I always feel comfortable in the hands of the hygienists and Dr. Jacob. I have brought up several of my dental concerns to him and he is always quick to offer his best professional advice. He also explains everything in very patient friendly ways too! Not to mention, he will consistently follow up and check- in following a dental procedure--he genuinely cares and wants his patients happy and confident with their smiles. Dr. Jacob offers new and modern dental treatments. If you're in need of Invisalign to straighten your teeth, I highly recommend going to his office. He has made my Invisalign journey very efficient. I would HIGHLY recommend him to anyone looking for a dentist in the north shore area. Looking for a new dentist that you will actually look forward to seeing? Don't hesitate and book with Mark Jacob right now! read more

Our entire extended family has been cared for by Dr. Jacob for decades. And when I say, cared for, I mean it, Plain and simple, Dr. Jacob is the best dentist I have had the privilege of seeing in my 66 years. He is kind, caring, and 100% patient focused. He recommends only what is best and right for each patient. We value, respect and appreciate everything that Dr. Jacob does for us. Thank you . read more

Dr. Mark Jacob is an amazing dentist! He is so precise and pays great attention to the patients. The hygienist staff is great and the office is beautiful! I cannot recommend this office enough. read more

Dr. Jacob and Dr. Orlando are the best Dentists I have ever had! They provide great, welcoming service and are very experienced in their profession. The two of them and their staff helped me with every step in the process of getting Invisalign, answering every question I had with great detail. I could not have asked for a better experience. I highly recommend visiting Deerfield Dentist for any teeth related needs. read more

I can't even explain how amazing Dr. Jacob is. I'm so glad I was recommended by my family to go to him. By far the best dentist I've ever been to and will continue to go to Dr. Jacob forever now. Highly recommend going to him. Trust me you won't be disappointed ! read more

Couldn't be happier with Dr. Jacob! After seeing more than a couple dentist it's a relief to find someone I know I can trust! Dr. Jacob and his staff are extremely professional and I would 100% recommend this office for any dental needs! read more

We had a cosmetic emergency the night before a wedding while visiting Chicago. We found Dr Jacob on yelp. Dr Jacob fit us in right away. He did a fabulous job fixing a veneer that had fallen off. King of Customer Service for sure ! read more

Been going to Dr. Jacob for several years ever since my father-in-law referred me to him. Very nice staff and a brand new office. Previously, I've always felt dentists were ripping me off, but I feel very comfortable with Dr. Jacob and I don't have to worry about him telling me I have a cavity when I really don't. I'll continue to use him as my go-to dentist in Deerfield. read more

Dr. Jacob is very dishonest doctor, I had a cavity on my chewing tooth and he recommended extraction, which I did . when I went to another doctor they told me he wanted to take the tooth out so he can convince you to get a implant. after a few months I found out he did exact same thing to my friend. We both stop going there. He also text you confirming appointment and claiming it's one of the girls working in the office. One day when he texted me and said the message was coming from one of the girls working in the office, I went to the office in 20 minutes and that girl was not even working there that day, I told him he should stop doing that. He could be very rude and he doesn't work for the benefit of patience. read more

My experience with Dr. Jacob has been fantastic. It's very obvious that he cares about his patients and is very knowledgeable and thorough. I would recommend him to anyone looking for a dentist that they can trust to do a great job! read more

Had tooth break off at gum line. Knew I had to have tooth pulled and an implant put in. Made an appointment as soon as they took appointments due to covid 19. In less than an hour tooth was pulled and implant was put in. Had no pain afterwards. I would recommend Jacob for all your dental needs. Very professional doctor who knows what he is doing. read more

Best dentist in Chicagoland! Let me start out by saying that I am a terrible patient, I gag, I'm inpatient and overall what dentists consider a difficult patient. Only at Dr. Jacob's Office I feel comfortable and confident that the best work is being done on me. His staff are very nice and understanding. Dr. Jacob uses state of art technology. He keeps up to date with new ways of doing dentistry. His camera in particular is amazing in that he can show me exactly what's going on in my mouth. He not only treats me but also educates me on how to better take care of my teeth. Would strongly recommend! read more

These are the only people allowed to touch my teeth! I've been a patient here since I was 19. I'm 32 now. Ask for Sandy, she's the best. read more

My only reluctance in granting Dr. Jacob 5* is that he continually cracks jokes causing me to laugh when I should be in mortal fear. Further, his musical tastes for the office are mocked by Sandra, Dr. Jacob's ace hygienist. Dr. Jacob is conservative and meticulous in every aspect of his profession. Keeps the patient updated on what will be happening next, only does what needs doing and incorporates the latest technology and procedures. His chair side manner is outstanding. I recommend Dr Jacob for anyone seeking high quality performance for their dental needs. read more

Dr. Mark came into the office on a Saturday to cement on a crown that fell off. I'm most grateful as I'm leaving town in the morning and he didn't want me to wait a week for the repair. I've been a patient for almost 30 years, and started out scared to death of the dentist. As I'm still with him and my anxiety level has dropped to a 2 on a scale of 10; I believe that tells you that he's a great dentist, very professional and personable. read more

I just want to say Dr Mark Jacobs is the Man I had a tooth ache since the beginning of this coronavirus era and couldn't find a dentist anywhere until Dr Jacob as his wonder staff and assistant Sam who made me feel great no pressure at all just so professional at all times made me laugh he was to the point about my problem gave me options on what I could do and we went thru with the procedure and it was a success no pain in the process just a little soreness hey if you guys want a swell great and intelligent doctor to pull or clean or anything with your teeth pick Dr Mark Jacobs he's the Michael Jordan of Dentistry You the man Dr Jacobs see ya soon read more

His office is sparkling clean and good looking. His staff is so nice and accommodating. I am so happy to have them and highly recommend! read more

I have been seeing Dr. Jacob for a little over a year now since I moved from the city of Chicago to the suburbs and my husband now sees him too! Dr. Jacob is smart, experienced, and friendly. His office is very clean and nice. He has done fillings and cosmetic work for me. His hygienists and staff are great, too. They are taking many additional safety measures during the coronavirus pandemic. I had a tooth emergency and he came in on a weekend afternoon to help me. I highly recommend him!!!! read more

10/10 experience. Walked in with a chipped front tooth and then walked out with a fixed front tooth (looks better than it did before) and two fixed cavities. Would recommend to anyone looking for a talented professional in the North shore! read more

He's the best! He cares about his patients and has saved the day for us with last minute appointments for "emergencies". He has done a variety of dental procedures on both my husband, myself and our 15 year old daughter...often coming up with solutions where others have failed. read more

I have been going to Dr. Jacob since..well..when do you first start going to the dentist? 6? He's the only one I've ever had + that'll never change! I'mm 26 now and he has seen me through braces, orthodontists, wisdom teeth, everything. His staff is the best (always has the nice hygienists, shout out to Sandra she's the best!!) and they really do care about all their patients. He knows everyone in my family and it's always so comforting to see a doctor who has stayed a constant in your life! They are hard to find these days. I travel from downtown Chicago see him and his staff too :) Totally worth it. (When you're little they have an awesome treasure chest of toys too..#memories) Thanks for my amazing smile + keeping my mouth fresh & fantastic!! read more

Dr. Jacob and squad is the best in the burbs. Always have the best service and receptionists are the best!

Can I give him 10 stars. Dr. Jacobs and his staff are qualified to operate a side business teaching the art of customer service. Make an appointment if you don't believe me. read more

I moved to the area and was having a hard time finding a dental practice that I liked. A friend recommended Dr. Jacob and he has absolutely changed my smile for the better over the last 5 years, seeing me through the Invisalign process and replacing a 20 yr old porcelain facing. I couldn't be happier with the results, and get lots of compliments on my teeth and smile. His office is new and clean and his staff very friendly. read more

This was my first of many visits to Dr. Jacob from the time I made my appointment to the time I left the office I felt 100 percent taken care of. I have never met a more professional office in my life so organized they give you full access to them email, text and phone communicate however you like which is nice super easy to make appointments. The office is brand new with all brand new equipment top of the line you felt like you were sitting in Beverly Hills dental office. Dr. Jacob addressed all my concerns he Made me feel so comfortable like I was family to him. I'm super excited to go back to the office I am grateful and lucky to have found such an awesome dentist!! read more

We've been coming here for over 20 years! Love Dr. Jacob! My kids have also been here since they had teeth! He is awesome with the kids! Everyone is very friendly and the office has a great atmosphere. Thanks Dr. Jacob! read more

One of the best around. I will not go anywhere else. Going to the dentist is stressful (for most). When I go to the dentist, always leave laughing!!! Gentle, kind, perfectionist, wonderful group of people who truly love what they do. I met Dr. Jacobs through my own business and have been seeing him for all of my dental needs. I highly recommend this wonderful group of people. You will not be disappointed. AND,,,the new office is beautiful.... read more
