Robert H Gregg II & Associates
If you have seen our pioneering dental laser featured recently on the evening news or in national magazines, you may be surprised to learn that our local practice is right here in Cerritos. Not only are we still seeing private patients, we are ensuring that each patient has a close working partnership with the doctor.

Our patients are encouraged to participate actively in their own dental care. We are committed to good communication, from the moment a patient walks through the door through the days and nights after a procedure. We believe this commitment sets us apart from other practices. For example, our dentists routinely call patients at home in the evening after a procedure to find out how they're feeling and address any problems.
Services
Our exceptional, friendly staff is our greatest asset. Our front office staff, dental assistants and hygienist are licensed professionals who pride themselves on staying on the cutting edge of dentistry and patient communication. They are excited about what they are doing, have high standards of quality and integrity and are motivated to achieve the best results for our family of patients.
According to the Centers for Disease Control, 80% of the population has moderate to severe gum disease, the major cause of tooth loss in adults, but fewer than 3% receive treatment. Using microdentistry to detect and treat cavities when they're first beginning helps prevent bigger problems later on.
Robert H Gregg II, DDS graduated from Georgetown University Dental School in 1984. He maintains a private group practice in Cerritos, California in the same location for over 33 years. Dr. Gregg began using lasers in clinical practice in 1990 and has been at the forefront of dental laser technology innovation and adoption.
Our team of dental specialists and staff strive to improve the overall health of our patients by focusing on preventing, diagnosing and treating conditions associated with your teeth and gums. Please use our dental library to learn more about dental problems and treatments available. If you have questions or need to schedule an appointment, contact us.

Dr Gregg thinks he's a god to perio. He's not only rude but tried the laser on a vocal cord that he fried even more then it was, he was trying to "stimulate" it!! He has temper issues as I heard him call a staff member an "idiot" and I hear he has a punching bag on his desk cause he can't handle his anger. Not someone I want near me with any type of tool especially a laser. Also he likes to have post it notes put-literally on his body, to let him know a patient is ready. Seems like he needs to back to kindergarten to learn the basics on how to treat staff and

For those of you who might be afraid of the dentist - or, if you had an "unpleasant" experience with some other dentist - DR. GREGG is the office you NEED to visit!
Whether it be getting your teeth cleaned, going for your regular check-up or some other procedure......, there is no better, friendlier or more comfortable way to go, than by visiting Dr. Gregg and his able staff!
From the time you walk in the door, to the time you walk out, it's like being with family (if your family were expert in all things related to dentistry).....
It's obvious that entire staff goes 'over and above' to ensure

Loved Dr. Gregg, he was patient and precise with my dental needs. After the treatment was over, Dr. Gregg went into details of what he did and next steps.

Exceptional service every time I visit. From the minute I walked in after being gone for a year I received a very warm welcome and a very sincere, "we missed you." Marika is the best dental hygienist. Thank you for removing a years worth of barnacles . Lol .

I am so happy I found the Dr's Gregg, Dawn Gregg has helped my deep pockets and loss of bone tremendously without the loss of tooth. Please, without them I would have endured root canals and possible loss of tooth without them. I cannot thank them enough, also thank you Vanessa, you are a sweetheart!

As a health coach and fitness expert my health is my calling card. Two years ago I discovered I had periodontitis. I was told by doctors that I would need multiple surgeries, pull teeth, bone graft, implants. It would take over a year, be very painful, and expensive with no guarantees. Than I discovered LANAP and Dr Gregg. What a game changer. Dr. Gregg performed a laser surgery on my gums and I couldn’t be happier. It was painless, quick, and a fraction of the cost. Dr. Gregg is a true innovator as the inventor of the LANAP procedure and laser. Everyone with even the mildest form of periodontitis

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

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

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

This Dentistry Office is state of the art and very pleasant to visit. The laser dental technology that was pioneered by Dr Gregg improved my gum health greatly and healed a pocket in my gum-line that constantly became imbedded with food and bleed prior to treatment.
I have received compliments on the dental restoration from this practice at other dental offices subsequently. I would still go to this practice if I still lived in the CA area, My family and I used to travel 90 minutes to visit him.
This practice has my highest recommendation.

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.

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!!!

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

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

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

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
