Very unprofessional, cold and not very friendly. When I had questions they wouldn't even return my calls. Not Recommended.

Here is the update today! Dr. Dawn had sat down and explained the complexity of my case. They will continue sticking with the treatment plan,and all the staffs are taking my case professionally and seriously. read more

I have been a dentist for over 25 years Dr. Gregg is a mentor of mine. If I ever need dental work I would be honored if he would be my dentist. read more

Robert H Gregg, DDS - Dentist in Cerritos - Oral Surgeons Near Me - Cerritos, California

This review is for Dr. Gregg's periodontal laser treatment -- BOY, DOES IT WORK!!! Saved my teeth! Healed my gums and restored my bone loss! My story: Like many people, I noticed my gums would bleed a little when I brushed, and I knew I had what they call "pockets" down under many of my teeth, especially my molars and wisdom teeth. My pockets had been probed and measured -- most of them were in the 9-12mm range. I even had a couple of 13s. Crazy deep. The dentists would try to do a deep cleaning once in a while, but would just shake their heads and tell me once you get a pocket, even a moderate one, the bacteria settle in and just keep digging. You can slow them down a little, but because you can't really clean the pockets at home, it's impossible to halt their progress. They destroy gum tissue, and then eat away the bone at the base of your teeth, making the pocket even deeper. For years, I lived with the terrible knowledge that I would either need gum surgery (oh great) or lose some of my teeth one day ... or both. Dread. Not a great feeling. One day, my wife found Dr. Gregg online, and I learned about his Millennium Dental program with the laser treatment (called LANAP). Exactly 4 years ago (Nov 2013) I drove up to Cerritos and had the procedure done. It took multiple visits, and wasn't comfortable, but believe me it was a walk in the park compared to doing it the old-fashioned way of oral surgery! Especially because oral surgery does virtually NOTHING to actually regenerate your lost tissue down below (which means there's still plenty of room down there for the bacteria to come back and take up where they left off). Here's the condensed LANAP procedure, as I recall it: -They numb you up with Novocain -They shine the laser down past your gumline, along and under each problem tooth -The narrow light spectrum of this particular laser targets the specific type of bacteria doing the damage (surprising science!), so it kills them all -The laser also destroys any dead and decaying tissue, leaving healthy tissue untouched -They clean out all the dead bacteria and dead tissue -They make a few scratches down below in the tooth/bone (totally painless) to release stem cells into the area -They use the laser to get the surface of the healthy tissue to bleed and clot, mixing in the stem cells -You go home and follow their aftercare instructions EXACTLY, because you take your healing seriously and want a miracle to occur -The clot stabilizes and becomes a tissue matrix, which over time transforms into new flesh and bone -You're blown away because a MIRACLE has occurred! Note: I did drive up to Cerritos (I don't live in that area) for the first year for follow-up visits/cleanings, because they know what to do and not to do after this procedure (I didn't want some random dentist or hygienist to go poking around under my gums and damaging the regeneration that was happening). Now it's been exactly four years, and my teeth and gums are amazingly healthy. After the first year or two, my probe measurements were down to 5-6mm. But my gum healing and bone regeneration have continued to occur, and my new dentist just measured my whole mouth at 2-3mm! No pockets -- like when I was a teenager! I told him I used to have pockets of 12-13mm. His periodontal specialist was in that day and confirmed the new measurements. They were blown away. When you have this done, Dr. Gregg may or may not do your procedure personally, but he is the actual inventor of the PerioLase technology, so you're in good hands in his office. I can't thank them enough for what they did for me. By the way, DON'T BE FOOLED by imitation periodontal lasers. Lots of dentists and periodontists around the country own Dr. Gregg's PerioLase unit (they pay about $150,000 for it), because it's the ONLY laser which does all this and is recognized by the FDA to result in regeneration. BUT a WHOLE LOT more dentists and periodontists buy BUDGET laser units that use generic technology (they can't use Dr. Gregg's patents). They'll tell you it's the same, but it's not ... so don't be surprised if it's a temporary fix and you wish you had upgraded to the real deal. You get what you pay for. I know I probably sound like an ad, but I'm not. I'm just a VERY HAPPY AND GRATEFUL PATIENT who asked a lot of questions and did a lot of research. Feel free to check out my many other Yelp reviews -- I've been leaving them for years. Thank you, Dr. Gregg! read more

My experience is along the lines of Lynette's. I have been going there for a number of years but cannot understand why Dr. Gregg has shifted his patients to inexperienced recent graduates. I know they need to gain some experience but it's irresponsible to leave your patients under the care of apprentices. The rates are the same as before but the level of experience does not merit the price. We have already had a tooth loss in our family during this transition and I will definitely be looking for an alternative.... maybe Lynette's recommentation. read more

I had a totally different experience than Lynette. That was 2 years ago and since then things have changed in Dr Gregg s office. He s now the only dentist and he s the only one to take care of you. I have nothing but great things to say about him. As a matter of fact I think he s by far the best dentist i've ever gone to. I went to see him after 2 of my best friends highly recommended him and I m so happy I trusted their opinion. I went to see him because I had a huge problem with my red gums and with one of my tooth. The few dentists i went to see prior to Dr Gregg wanted to put me to sleep, extract the tooth, do some bone grafting and then an implant which would have been extremely expensive. As far as the gums they wanted to do a deep cleaning which i ve never had one done before. He basically told me that I didn t need a deep cleaning but only a regular cleaning and a bite adjustment which ended up being the best thing I ve ever done in my life. My gums are not red anymore and my headaches are gone too. This 3 sessions bite adjustment is really affecting my health very positively. I m so excited to have a more restful jaws and sleep better because of it. As far as the tooth well he basically saved it. What others thoughts was decay was only discoloration as he predicted earlier. The tooth didn t break or anything and i just ended up with a new crown. However He had to do a gum grafting but it was so painless I didn t even need to take any pain medication. The office is not too exciting and is very old fashion but I know that whoever goes to see him will be very happy. Don t get fooled by the look of it. The quality of the treatments you get is outstanding. I also need to mention the fantastic helpful fun staff who assist Dr Gregg. Those Girls are so nice you can t help but relax. It s definitely a joy to go there. He s also the famous dentist that invented the laser for gums. A few of my friends have done that and since then their gums have changed dramatically. They don t have to do deep cleanings anymore. So yes I do highly recommend Dr Gregg. It s always so hard to find an honest excellent dentist. This is one of them. Carlos Rosario read more

I just had a cleaning at Dr. Gregg's practice, and as usual, it was a great and painless experience (I know how much people are afraid to go to the dentist!). I've been going here for a few years now and it's always been a pleasant experience. Let's start with the waiting room as they always have a huge selection of magazines that are current. I hate when I go somewhere and they have an issue of Sports Illustrated from a year ago. They also have fresh Starbucks to sip as you wait. Granted these things don't have anything to do with the actual dental experience, but these small touches improve the patient's overall experience and lets one know that Dr. Gregg and his staff are all about customer service along with great dental care. I usually go to see Marika, who is excellent. She has a bright smile and puts me at ease even though she's going to be poking and prodding the inside of my mouth for the next hour. It's particularly great because she has fantastic sports knowledge. In between opening my mouth, we talked about the NFL Championship games this past Sunday and she knew just as much as anybody. It's kind of like sitting in a barbershop and just talking about things, but I was actually sitting inside a dentist's chair. On to the actual cleaning and other experiences: In one word it is COMPREHENSIVE. A year ago, I kept having constant jaw pain and headaches. Dr. Gregg and company were so thorough that they found out that I had been grinding my teeth while I was sleeping. Dr. Gregg was great in providing me with a mouth guard to prevent me from ruining my teeth at night. Another thing to consider when you come here is the use of their dental laser. The first time I came I had no idea what it was except that I've never had a dentist use one on me. At the end of each cleaning, they use a laser to touch up rough spots in your gums. I can't really explain it, but I know that when I leave I have minimal bleeding and soreness in my mouth and gums. If you want a solid dental experience with state of the art technology then this is the place to go. read more

Exceptional service. Been a patient of Dr. Gregg since 2002 and he is very ethical and meticulous with his work. Perfectionist! Would highly recommend their periodontal laser treatment work. Their staff Marika is a very professional hygienist and I wouldn't change her for anyone one. What is key to any business is their front line staff and Carla Valle will always greet you with her warm smile and goes that extra mile to ensure all your dental needs have been addressed. Their office management Veronica Santa is truly a friend and methodical in her work ethic and always provides sound advise and recommendations. Kari Barello is also a very skilled professional. I live in the east end of the San Gabriel Valley and travel to see Dr. Gregg. It's all worth it and they make you feel like family. read more

I used to see his associate Dr Chad. I had Laser surgery with Dr Gregg and that's what he specializes in. He put off giving me a check up for over a year. Even when I went in for laser surgery, he didn't give me a comprehensive check up but billed my insurance co as if he did. He's really just interested in doing laser treatments and nothing more. His office staff is unprofessional and the only reason I kept going back was because Marika his hygienist is awesome. I would recommend him if you think you need gum surgery. Dr Gregg will laser them instead. Go to Dr Gregg for any other type of dental work and he'll most likely recommend laser for everything. In my opinion he should just specialize in laser surgery. Having a sign on your business stating general dentistry and steering patients towards laser treatments is misleading. read more

I came to find Dr. Gregg's office after being told by my regular dentist that I had advanced gum disease and significant bone loss due to the gum disease. She said I was in danger of losing teeth as well. She recommended that I get something called a Flap surgery. She explained what that was and I burst into hysterical tears, already having my mind made up that I would never do such a thing. I didn't care in that moment that my teeth could fall out. It's archaic and what I've come to call a caveman procedure. I drove home from my old dentist office in tears thinking to myself that their had to be another option. It's 2015! Not 1950, I wasn't about to let anybody cut off my gum tissue and sew it back together...not to mention the fact that a lot of people who get flap also wake up to find out that they have had teeth pulled because they were deemed un-savable by their periodontist. So I got home and started doing some research as at 36 years old I wasn't ready to lose teeth but I wasn't going to do the Flap either. I came across something called LANAP. Sounded minimally invasive and pretty successful...It also sounded WAY too good to be true. So I furthered my research and decided to go for a consultation at an office near where I work in Sherman Oaks. They did the consultation and I left. I wasn't really satisfied with the office or their explanations of anything. So again, I furthered my research and came across Dr. Gregg and how he was the one that developed the procedure. I then watched and read everything I could find about this procedure..I decided to give their office a call to see if I could get some more detailed information about their office and Dr. Gregg. I got on the phone with Kari (who is the best by the way!) and she stayed on the phone with me for well over an hour explaining to me everything about the LANAP procedure and the benefits and what to expect. All the while NOT ONCE pressuring me to come to THEIR office just completely willing to offer me some time out of her busy day to help educate a person who wasn't even a patient at their office about this procedure. After my conversation with Kari, I scheduled a consultation with Dr. Gregg. I was ready to meet him and make this happen. The consultation was short, but mostly because I had done so much research I didn't really need to ask him much at that point. I had my initial pre-procedure exam done within about a week of my conversation with Kari. They x-rayed me and measured my gums where I had a mouth that had no better number than a 3mm and the worst one was a 12mm!!! A 12!!!!! If you have gum disease then you know that's an unacceptable number and serious danger of losing that tooth! If I had had done the flap procedure they would have pulled that tooth no doubt and judging by the numbers I had (mostly 6-10mm) i'd have lost more than just that one tooth. So I am a pretty serious case, I got my estimate and while, yes, I have to say the procedure isn't cheap but what can you expect and what is your smile worth to you? I wanted to keep my own teeth... I opted to open a Springstone account where they offer you 0% and you can make payments. I had the procedure done, in two sessions (half of your mouth at a time) and yes it's uncomfortable but by no means does it feel like "surgery" There are no stitches, there is no cutting. They numb you with a topical, and then novocaine so by the time Dr. Gregg gets in there you don't really feel much. The recovery time is also not really bad (other than the soft food diet haha), I was back to work the next day with some swelling but I was able to fully function at work. Within a week I could tell that my mouth was getting better and I realized just how infected and puffy my gums were before the procedure. When I was allowed to brush and floss again I had no bleeding. There was no more puffy gums (which I hadn't even noticed until I had the procedure as it had progressed over several years) I follow my aftercare exactly as recommended because who wants to spend all that money only to mess up the work by not flossing or going to your followup visits & having your regular cleanings. Aftercare is key. Follow it! It works, if you don't you only have yourself to blame if you don't get the results you want. I had this procedure done in August of 2014 and have been waiting to post my review because I wanted to wait until we did the one year measurements of my gums. Well the results are in folks, I officially have NO danger of losing any of my teeth, all of my numbers have improved from 6mm-12mm which I had pre-procedure to 2mm-6mm. Now keep in mind that those 6mm's that I have now were once 9's and 10's. The 12mm I had is now only a 5mm. If you have been told that you have gum disease that requires surgery, I'd seriously suggest that you do some research on LANAP and Dr. Gregg and his work. I couldn't be more grateful for him, and his whole staff. Thank you guys for saving my teeth! Worth every penny!!! read more

Had an awesome experience today at the dentist. I must say, I have never had my teeth that thoroughly cleaned before...Marika, the hygienist, is very detailed and highly skilled at what she does. What a sweet bunch of girls there too. After today, I'm looking forward to my first exam with Dr. Gregg. Thanks guys!!! I will definitely spread the word!!! read more

Dr Gregg is the best dentist to ever work on my teeth. My last dentist had missed two cavities until I ended up needing a root canal and an extraction. Dr Gregg worked carefully for months until he got rid of the abscess and every trace of infection. Then he put in handmade crown that is a work of art. He may not be the fastest or cheapest, but I'll never have any problem with that tooth in the future. His staff members are courteous and arranged an affordable payment plan. A friend recommended Dr Gregg as the best, and she was right. He really is the most skilled and gentle dentist you can find. read more

I really appreciate the quality of care I get here. Probably due to a lifetime of poor dental hygiene before I found Dr. Gregg, I have had two occasions of receding gums (periodontal disease?). That laser-assisted new attachment procedure (LANAP) of his is absolute genius. The thought of old-school scalpel and sutures gives me chills. LANAP heals fast and beautifully. read more

HIGHLY RECOMMENDED I was referred to this office thru a friend of mine after learning I needed gum surgery. She said he had saved her teeth, so I decided to give him a try. Best dentist I've ever been to. Dr. Gregg and his staff made me feel at home. His staff is great and he clearly knows what he's doing. He treated me with a laser so I did not have to go through the cutting and bleeding and stitches. I went back to work the next day and felt fine. read more

I had the best experience with this dentist having laser gum surgery. Dr. Gregg's team was able to save a tooth which would have had to be pulled and an implant inserted. And, my other teeth and gums were also treated so I wouldn't have an issue with them in the future. I would definitely recommend Dr. Gregg for any laser surgery. And, his whole team were equally accommodating and made me feel very comfortable. read more

Dr. Gregg is an excellent and caring dentist. My history with him goes back many years. He is exacting in his work and dedicated to the patient. read more

Dr. Gregg is a great dentist. Unfortunately, he shifts his patents off to his "associates", who are frequently fresh out school and in training for his laser technology. The first associate I had was great at discussing his surfing activities, but not good at replacing my TMJ night appliance. The replacement appliance was defective and I ended up with jowls like a bulldog. The second associate was sweet but when I took my stepmother to her, she couldn't handle the complications that my step-mom had. The office kept telling me that they would call her when they got the special film they needed for her x-rays, but they never called. The third associate, Dr. Chad, is gorgeous, kind of like a modern day Ben Casey. But he was fresh out of dental training. He asked his assistants for advice a number of times. He recommended that I have a re-do of a past root canal at a local specialist. It was one of the worst experiences of my life. When the procedure was finished, the endodontist told me to go back to my regular dentist to have the tooth restored. Dr. Chad didn't want to fill tooth because there was still a small shadow at the root. Two weeks later, I broke the tooth. Dr. Chad said he couldn't replace the crown and said he had to pull the tooth. It's the first time in my life I've ever walked out of a dentist's office. I contacted my daughter's dentist in Fountain Valley. Dr. O'Connor replaced the crown. It's been 2+ years and everything's great. And he hasn't tried to sell me the moon and stars every time I've gone to see him. His dental hygienist is wonderful. If you go to Dr. Gregg, make sure that he doesn't offload you to one of his trainees. The price is the same, but the level of service and expertise is vastly different. read more

I can't recommend Dr. Gregg highly enough. I had to go in for an emergency root canal treatment two weeks ago, and it was (amazingly!) almost entirely painless: I needed only minor medication for a day or after the surgery and that was that. Everyone in the office is super nice to boot, especially with squeezing me in for an appointment the day after new years (I cracked my tooth, hence the need for the root canal). I've heard such scary things about root canals, but this was pretty much a breeze. Dr. Gregg and his staff took the time to explain to me what was going on throughout the multi-week treatment necessary to perform the root canal and order the new crown, leaving me a very informed patient (which I have never felt at other dental offices). read more

I went to Dr Gregg because my family dentist (and his office's periodontist) recommended periodontal surgery for me, and I wanted a second opinion. Dr Gregg is a founder of the LANAP procedure for laser gum treatment, so I surmised he would be the best person to give me his opinion. To my surprise and relief, Dr Gregg examined me and concluded that I needed no cut-and-stich traditional gum surgery, nor his LANAP laser procedure offered at his practice. I am happy that he saved me from expensive treatment. read more

best dentistry team and office team ever. Nice, accommodating and works well with super scared patients like me.

If I can give less than one star I would, few years ago he did my laser gum surgery at his office and charged me over $5500 for it, for the follow up he never saw me always I had to be seen by another trainee. I called his office last week because I had a very bad gum infection I couldn't open my mouth, I explained my situation and I was given a 9:00 am appointment, I asked them if I can come at 9:30 because I live far, they insisted on the 9:00 because they want to see me first, I appreciated that. I left my house very early to make it on time, I arrived at his office at 10 minutes before 9:00, I waited until 9:15 when the receptionist gave me paperwork to fill and she said I have to wait they will be in meeting, I tried to explain that I was in pain and I was asked to come early to be seen she ignored me and disappeared in the back for her meeting. She came out at 9:45 asking me to take x-rays I explained that I couldn't open my mouth for the x-rays and I offered to come back for it when my infection is gone I just needed antibiotics for the infection, I asked her if I can talk to Dr Gregg he was familiar with my case. She came back to tell me that Dr Gregg said he can't see me if I don't take the x-Ray. He did not have the curtsy to talk to me. I left and saw another Dintist who was surprised why Dr Gregg refused to see me, he prescribed the antibiotics and pain killer and I felt better in few days, I was ready to take the x-rays then. I heard a lot of bad reviews for Dr Gregg but I wanted to give him a chance, but I was wrong he is the worst Dintist I ever seen he is in for the money. He doesn't care about his patients he only care about him self and how much money he can get out of each one. I will never go back or recommend him to anyone. read more

This office is one big joke. I had very bad gum recession on my bottom tooth and had been told for many years from other dentists even, that this was something I had to fix or I could lose the tooth. I finally went to Dr. Greg's office for help. Now, Dr. Gregg isn't really why i am giving this office such a horrible review. But, it's his allowing his staff to be so inadequate. I paid out of pocket over $2,000 to get this procedure done. They insured me that I would be reimbursed by my insurance company. Months go by, a year goes by, no reimbursement. I follow up constantly. They FINALLY admit they fired the girl working the front desk and she didn't fill out the request for reimbursement properly, that they would resubmit it and get back to me. Long story short, here I am years later, never being reimbursed. I even called a couple months ago and the girl who answered said she would definitely look into it, resubmit it and call me back. AND NOTHING. It's just shitty practice. I totally got the run-around. False promises and pathetic staff. Stay away from this office. read more
