Check out what some of our happy patients are saying about us:

Corina S. from Carlsbad, CA (Source: Yelp)


I am extremely afraid of going to the dentist. I have had very bad experiences in my lifetime and because of this I rarely go unless I have a major issue. It’s probably been somewhere between 7-10 years since I saw a dentist.  A friend of mine recommended Dr. Assadian and his team.  I was in pain for about 5 months and decided I’d take care of it before the end of the year. I was so embarrassed and scared when I first walked into the office.  I cannot express enough how WONDERFUL this staff is. They were very caring and understanding and made me feel so comfortable. They were able to walk me through each step and as soon as the treatment started, I realized I was going to be ok.  Most of my anxiety was gone within a few minutes. It did not hurt and ALL my past fear was gone. I will be able to see the dentist now every 6 months as recommended as I’m not afraid anymore. I HIGHLY recommend Dr Assadian! He’s the best! Technology has  changed a lot when it comes to dentistry making treatment less painful. Dentistry 2000 has truly changed my life and it can change yours too.  Please don’t wait like I did. Go see them and you too will be as happy as I am. I have never posted a yelp review until today, but I had to let others know that they can trust this staff. 🙂 Thank you Dr. Assadian!

I am so happy with the care I received from Dr. Assadian and the assistants at Dentistry 2000. I was made to feel comfortable and did not experience pain. Dr. Assadian is careful to explain things carefully and I had all of questions answered thoroughly. I am so relieved to have a dentist I can trust to help maintain my teeth!

This place is amazing I love the people that work there , they get the work done fast and there is no waiting time to be seen if your schedule a time I love dentistry 2000

Alkuno T. from Oceanside, CA (Source: Yelp)


I had been seen the previous month from a dental clinic located at Mission Marketplace, Oceanside which I described as unprofessional for forcibly insisting to replace a dental crown.  But I was very relieved and thankful that Dentistry 2000 took care of my dental needs. Though they offered to replace the old dental crown – they were not insistent when I hesitated as I feel that it’s still usable. Dr. Assadian was very informative of the treatment I received.

The staff is always very accommodating, kind, friendly, and funny. It’s the kind of place you don’t want to go to, because, you know, no one likes getting their teeth worked on, but you love because they make it worthwhile. Love them!

Phyllis M. from Carlsbad, CA (Source: Yelp)


I don’t normally write reviews, however, I feel I need to for Dr Assadian. I had a fear of dentists because of a bad experience a few years ago, so I get very nervous when I need serious work done. I went first for a deep scaling, the hygienist was the best I’ve ever been too! Then I needed some more serious work done, from the minute I sat in the chair, everyone from the receptionist to the dental assistant and of course Dr Assasdian made me feel so relaxed that I had no fear at all. What a great feeling! I have never felt more comfortable in a dental chair. He is unbelievably gentle, thorough and a did a beautiful job. He educated me on dental hygiene more than any other dentist I have been too, I believe he truly cares about my teeth and gums. I will never look for another dentist again! I just wish I had found him sooner. The entire staff make you feel so at ease. I actually look forward to going. I’m not kidding! If you have a fear of dentists, believe me, he will change your mind. And you get beautiful work done too!

Bill D. from Oceanside, CA (Source: Yelp)


Excellent service and very patient staff.  They tend to be great at helping us find the lost cost effective treatment plan available. Very experienced and made the whole process painless and took the stress out of the experience.

I am beyond thankful and happy to share my experience. I have a lot of problems with my teeth and got recommended to Dentistry 2000. I have visited many dentist but none ever made me feel safe and gain my trust so quick like Dr.Assadian and his great staff! I am still in the process of fixing my teeth. So far I got a deep cleaning and 6 crowns in my top front 6 teeth and it has completly change my life. Dr. Assadian took his time to made sure the crowns fit perfect. He truly cares about his patients.Im very happy and blessed that they recommend me Dentistry 2000 and be able to fix my smile. I recommend this place to everyone!!!!

Have been going to Dr Assadian, Loraina and Zenai for years and they are honest, professional, kind and work very hard. Is indeed rare to find these qualities these days. Their wok is excellent and the Dr. is a great clinician who really cares, again a rare trait. If you have been unsatisfied by dentists try Dentistry 2000. You will not regret it.

Elaine S. from Oceanside, CA (Source: Yelp)


Dr. Assadian and his staff are very professional, friendly and make the experience of going to the dentist a pleasant experience. If you are looking for a GOOD dentist who has a “state of the art” dental practice, then this is the place to go

Cara S. from Oceanside, CA (Source: Yelp)


Sent my husband here to repair a broken front tooth. He’s very picky. His own dentist had just retired. I picked this place for him based on the reviews and convenient location. His bedside manner was wonderful. Service was quick…no waiting. He runs a good practice!!!

Nick Hawk (Source: Google)


So I’ve put off my dental work for years and when it was finally Time to bite the bullet and get some work done I went to dentistry 2000. Not only did I receive excellent treatment and great customer service, but they worked with my budget and got me the best deal. I would recommend this office to anyone looking for reliable and dependable dentistry.

Jill D. from Lilburn, GA (Source: Yelp)


I have been seeing Dr Assadian for over 10 years. In 2014 I moved to Atlanta. I still come back  when I’m in town on vacation. Have not found a dentist  I like enough/ as much. I trust him and his staff completely!

Tye S. from Vista, CA (Source: Yelp)


I moved to Vista in 1994 and for the next 15 years drove to Santa Monica (200 miles round trip)  for dental care.  I’d had the same dentist, since 1986 and I never considered going elsewhere.  My teeth are sensitive, drills ah drills.  I’d had poor experience with dental professionals and my distrust was at a peak, when I met Dr Y.  She persuaded me to see her regularly and convinced me to trust her, by listening to me. Dr Y was able to get and keep my teeth/gums in good condition. 2009 I slowly began to realize,  that I had to find a dentist closer to home. My teeth were not being well cared for because that 200 mile drive, had become a difficult trip.  2009 – 2012 I saw 2 dentists down here and still was not caring well for my teeth, they were okay, just not for me.  In 2012/13 I found Dentistry 2000 and met Dr Assadian and his team of professionals!!   He and his staff are all warm, caring people, kind and soothingly cheerful, calming a slightly stressed patient.  It didn’t take long for my stress level to drop to zero, as I experienced the great care and gentle dentistry with Dr Assadian. One final word, as Dr and Team work together, it is calming. It’s clear they have good regard for each other’s abilities and readily anticipate each others next step, with barely a word, as they care for my lovely teeth

Paul M. from Vista, CA (Source: Yelp)


I’ve been going to this office for about 2 years and have always had a pleasant experience with Dr. Assadian and his staff.  They all come across and caring, informative, and genuinely friendly people. I would definitely recommend this office to anyone seeking an awesome dentist in north County.

We’ve been patients since 2008 and as our family has grown, they have also become patients. From cleanings, to crowns, pregnancies and being wimpy to pain, Dentistry 2000 has been GREAT!

Ali A. from Los Angeles, CA (Source: Yelp)


I have been a patient here at Dentistry 2000 for the past 4 years. I find it one of the best denitstry I have ever been. I will be honest. I am afraid of dentist. I had to put a crown. I was so worried. Dr. Assadian and his staff put a lot in helping me over coming my fear. They had the patience to deal with patient like me. I find everyone there friendly, caring, but more importantly professional. Although I have moved out of town but still I travel all the way to them

Jenny Ziegler (Source: Google)


Dentistry 2000 exceeded my expectations from the very first phone call! As someone who has had some really bad experiences with dentists, I was so hesitant to make an appointment with anyone. I was immediately put at ease by the warmth and professionalism of Dr. Assadian and his entire staff. They were comforting, direct, honest, and kind at every turn. I’m definitely a patient for as long as they’ll have me. I finally left a dental office without feeling like I was cheated. Quite the opposite – they even gave me snacks when I signed on for a longer visit than first scheduled! Thank you Dr. Assadian and Dentistry 2000, you are really one of the “good ones”!

Heidi Hitt (Source: Google)


I love Dr Assadian! He is very caring and compassionate. Throughout the years, I have needed multiple crowns, and I have always received excellent care at Dentistry 2000. Dr Assadian and his staff are very personable… it’s obvious that they enjoy helping their patients and their community. Five stars isn’t enough!

Jazmin C. from Oceanside, CA (Source: Yelp)


I had recently enrolled into my job’s dental plan and while looking through the list of providers I had stumbled upon Dentistry 2000. I looked through their reviews on Yelp and decided to give them a shot – and I’m so happy I did. This was one of the best experiences I have had at any dental office. Dr. Assadian and his staff were personable and informative. Unlike the other reviews I did not feel pressured to do or accept certain procedures that I did not want to take. I had gone to previous dental appointments in the past with other dental offices and when I would ask about certain problems I had with my teeth I felt like they pushed them under the rug and provided me with false or quick answers however, Dr. Assadian made sure to address those issues and inform me what the root causes were and I felt a sense of relief that I was finally given actual answers to my questions. I cannot wait to come back for my next visit


Jimmy V. from Oceanside, CA (Source: Yelp)


I recently moved to Oceanside and had to find a new dentist as I was in need of a  couple of new crowns.  My insurance provider gave me a directory of all the dentists in network in my area.  I checked each one out on social media and decided on Dr Assadian as his patients say very nice things about him.  He and his staff are all extremely nice.  They never kept me waiting.  The Dr. himself gave me great attention.  I essentially felt no discomfort during any of the drilling.  The crowns were back in just a little over a week and fit very nicely.  I was very pleased

Sheila Mata (Source: Facebook)


Dr Assadian is the best! My teeth were not what I wanted, he recommended a line of treatment to help my teeth be the best they could be. Pleasant, nice, funny, smart. Nice office staff.

Anita Andersen (Source: Google)


Dr. Assadian is absolutely The Best! I was a Dental Asst.for years and he is proficient in every way. A Master of his craft. He is engaging, explains the procedure he will perform, and is welcoming and kind. The staff is knowledgeable, cheerful and courteous. I would highly recommend this dental practice.

Natasha Kay (Source: Google)


I’ve had horrible dental experiences and therefore HATE going to the dentist. I found Dr. Assadian online and I feel so lucky that my family and myself have such an honest, caring dentist. He’s really great and makes you feel like family. Staff are super sweet and helpful as well. Totally recommend this dental office!

Jon H. from Oceanside, CA (Source: Yelp)


I came to Dr Assadian with TMJ,  a lot of pain, and an occasional locked jaw (in the open position, not pleasant). My bite had been mis-aligned from childhood orthodontics 40 years prior, and over many years the joint had suffered severe damage. Dr Assadian to the rescue!  He crafted a modified mouth guard which allowed my jaw to find it’s correct position regardless of the mis-alignment of the teeth.  After 3 months I was completely pain free! I now have a new jaw position which will prevent further damage to that pesky temporomandibular joint. Dentistry 2000 is a great group of people, Dr Assadian and the staff are knowledgable, open, considerate and efficient. 5 stars for pain-free living.

Brandy S. from Peacock, Oceanside, CA (Source: Yelp)


Going to Dr. A changed my life. I was a daily headache sufferer, spending thousands in treatments and medications with primary care physicians, therapists, and anyone else that would help try to take the pain. I’d seen several dentists before Dr. A but none of them saw what he saw. The wisdom teeth I still had were causing pressure and impact on my mandible bone, ultimately creating tension. I was always told I didn’t need to have them taken out…. My mouth was big enough. Dr. A knew better and solved the problem. The daily headaches stopped after extraction. At 35 my daily life was renewed. During the process I was a ball of anxiety and riddled with fear. I’ve always feared the dentist. Dr. A and his staff are friendly and gentle. While in the chair Dr. A asks “Are you ok” every sixty seconds, at least. Even during a simple exam. They listen to your needs and take care of you as a patient, and not as just another mouth. The staff is there for you and it feels that way. I highly recommend Dentistry 2000.

Nick J. from Oceanside, CA (Source: Yelp)


It is difficult to find a great dentist and easy to find reasons to not go to the dentist. I am so glad that I found Dentistry 2000. Dr. Assadian and his entire staff are welcoming, professional and sensitive to patient needs and preferences. I’ve had general cleanings and more intrusive procedures and they have always been in a relaxed and comfortable setting. I only have good things to say. Thanks again Doc and thanks to your office staff and assistants as well. I would highly recommend Dentistry 2000 in Oceanside to anyone, especially those who aren’t entirely fond of dental visits like myself

Donna C. from Oceanside, CA (Source: Yelp)


I cannot say enough about how wonderful and professional the office of  Dentistry 2000 is. Dr Assadian is very calming and patient as he helped me through a very extensive visit correcting my four front teeth. I cried once I saw what “miracle” he performed in replacing crowns that were placed by other dentists many years ago. After 40 years I am so happy smiling with pride !! showing off my new teeth!

Jody Gorran (Source: Google)


As a brand new patient, it took a leap of faith to trust Dr Assadian, whom I had never met before, with replacing one of my 20 year-old crowns. However, his willingness to explain in detail what my situation was at the present and how he would deal with it, convinced me to undergo the procedure. Suffice it to say that he and his staff exceeded my expectations. I was extremely satisfied with the process and intend to remain a patient of Dentistry 2000.

Mark Weller (Source: Google)


The staff here are very friendly. Some dental issues I had were discussed with me thoroughly both verbally and through anatomy media on an iPad. Dr. Assadian has a fun wit about him and constantly checks in with you throughout treatment. Very satisfied with the facility, staff, and treatment I received.

Gigi G. from Chula Vista, CA (Source: Yelp)


Dr. Assadian is such a wonderful, humorous, and overall very welcoming dentist that makes you feel super comfortable as he explains every procedure he is going to do before he actually does it. I got my wisdom teeth removed and I was honestly excepting it to be a brutal surgery, but Dr. Assadian would ask how I was feeling every minute and the surgery was over in just a few minutes. The healing process was a piece of cake and Dr. Assadian made sure to follow up with me to see how everything was going. Definitely the best dental experience I have ever had!! I am beyond excited that I found such a committed and professional dentist. Very reasonable prices and the team at Dentistry 2000 exceeded my expectations! Thank you so much for such a wonderful experience 🙂 !!

The Dentistry 2000 team is great! Both at helping you get results and making you feel comfortable along the way. Dr. Assadian, Sanae, Lorena, Ashley, & Maria have all played a roll when it comes to my visits and experience at their office and they’re the reason I keep coming back. I’ve been going to them during my Clear Correct process, I’ve had wisdom teeth pulled, and more… I’m so thrilled with how everything’s turned out. My mom comes here as well. We’ve had some horrible experiences in the past with a dentist when it comes to being lied too and ripped off financially. So we searched for a long time for someone we can trust… this is huge for us. So finding a place like Dentistry 2000, we’re truly grateful. Blessings.

I absolutely love everyone at Dentistry 2000! Not only are they gentle and thorough in all of the dental care you receive but you truly get the feeling they care for you. Plus I went in the day before my birthday and received a gift on the way out. I couldn’t have felt more appreciated as a patient. I highly recommend Dentistry 2000 to anyone

We’ve been going to Dentistry 2000 for almost 18 yrs now and we’ve always been treated like family when we come. The staff are very friendly and always do their best to help us with whatever needs to be done. If you’re looking for a family dentist, you’ll be hard pressed to find anyone better

Kelly S. from Vista, CA (Source: Yelp)


I reviewed recently but I need to again. I had a root canal on a cracked tooth (from an endodontist that Dr. Assadian recommended) and he was amazing so I come back to dentistry 2000 and have the temp cap put on, and they weren’t sure the tooth was going to be able to be saved. I was so sad to hear this because of how much was just spent on a root canal! But, with all of Dr. Assadian’s tools and know-how he was able to save my tooth! He was amazing!!! Also, I went in to have my wisdom tooth pulled and I wish I would have timed it… Granted it wasn’t a super complicated or impacted tooth, which can take more time I’m sure, but I really wish I would’ve time how long it took him to pull my wisdom tooth, it had to have been maybe a minute or 90 seconds. I couldn’t believe it!!! I am so thrilled!!! Pain free too! I just want to say thank you a million times over to Dr. Assadian and his whole team. I’m pretty scared of dentists (I’m 30 and shouldn’t be such a baby – but I AM!) and the entire team makes you feel SO comfortable and so at ease. I can’t say enough good things about this place!!
