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

Nobre N. from Oceanside, CA (Source: Yelp)


The Best I’ve had.  I use to be afraid of going to the dentist and use to procrastinate it until my friend told me to see Dr. Saiki.  His shots ARE PAINLESS.   I didn’t believe it until he told me I already had the shot and I was still waiting for it.  He is so laid back and talks to you about anything and puts you at ease. He explains everything to you to make sure you understand.  His office is really cool and up to date with new technology which helps make you see what he sees. His whole staff is friendly, like family.  Thanks, Dr. Saiki, for keeping me smiling. : )

Simply the best! I have referred many people to Dr. Saiki and every single One comes back saying he is the best. He made them feel so comfortable, explains the various options and what your current needs are. A lot of dentists immediately try and up sell you rather than being honest. Dr. Saiki has impeccable integrity and honesty you will not want to go anywhere else. His care for his patients is what has made him one of the leading dentists in our state. He puts people first!

Patricia T. from San Diego, CA (Source: Yelp)


I have had some bad experiences with dentist in the past so was skeptical at first. I was quickly put at ease  by the actions of all staff members. They are all friendly and helpful. Dr Saiki explained all of my options and we decided on a plan together. He has gone thru the process with me several times. I am completely satisfied and grateful that 1-800 dentist recommended him

Detailed, honest, and truly as good as it gets! I cannot possibly give enough of the utmost praise to Dr. Saiki and his entire staff.  You’ll get a crash course in teeth and his conservative approach means you won’t spend thousands getting an unnecessary treatments.  Exceptional in every way!

Holly S. from Ivey Ranch / Rancho Del Oro, Oceanside, CA (Source: Yelp)


Dr. Saiki is the best dentist around. He is professional and honest. He will not recommend unnecessary procedures as other dentists do. He and his staff are friendly and kind. I actually look forward to my visit because of the way I am treated. You won’t be disappointed if you choose Dr. Saiki as your dentist

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


I have been going to Dr. Saiki for at least 15 years. I trust his work without any doubt. He is conservative about how much needs to be done and what his plan is,  and excellent in the work done, and very up to date in technique. He is a kind and honest person that you can trust. The entire office staff is the same. Lovely people. Ophelia, my Dental Hygienist,  is great! She has made sure my gums are in good shape, and we work well together! Thanks guys!

Since moving to Carlsbad, CA I immediately sought the best Dental Practice. A lovely lady at the Carlsbad Senior Center recommended Dr. Saiki. I was more than pleased upon our first meeting. It has been more than 5 yrs now. Dr. Saiki and all the dental staff take excellent care of my dental needs. I am seen on my regular appointment schedule, I see the doctor and receive (good) reports, suggestions, feedback. My hygienist gives me honest feedback and suggestions for needed changes so that I may keep my Senior teeth in the best of health. Thank you to Dr. Saiki and staff. You are my very best choice in dentistry

I am down here in Carlsbad on vacation and I. Broke a tooth. The amazing staff was able to slip me in within 2 hours of the break and get me fixed up. I absolutely hate going to the dentist but I was taken back by the outstanding  work of DDS Saiki! No pain at all not even the shot into my gums hurt. Great bedside manner and just an all round cool guy. Highly recommend from a person that hates the dentist office

Had an emergency while traveling through town. These people bent over backwards to squeeze me in! The front desk girls were great and assisted me on The paperwork, Beth the dental assistant was very conscious of my large tori while taking xrays, and dr. Dean was very careful during the exam and explained himself very well!!!!!I would go back here if I lived in the area, and am trying to get our kids who live nearby to start here!!!! They exceeded expectations in a HUGE way! Thank you everyone!!!

Chrissy K. from Alhambra, Los Angeles, CA (Source: Yelp)


I’m happy to say that Dr. Saiki is finally on Yelp! He’s definitely the BEST dentist of all time; not only in San Diego County, but in LA County as well. Growing up, I hated going to the dentist, dreaded it, and sometimes even avoided it. After coming here, I’m no longer afraid to go to the dentist and actually look forward to getting my annual cleaning. I travel here from LA, and can definitely say that it’s well worth it. The staff is always friendly and respectful. They try to work around your scheduling needs. Hygienists are great, and are consistent with how they clean your teeth. Dr. Saiki is honest, trustworthy, and dependable. And is not like other dentists who will take the “easy route” giving you unnecessary treatments. Anytime someone has a dental question, is scared of going to the dentist, or simply needs a cleaning, I always refer Dr. Saiki. He’s passionate about his work, and cares for all his patients. One tip is to book an appointment early! Because he’s the best, he can be booked pretty quick! Parking: Free parking lot

My whole family has been going to Dr. Saiki forever. The office staff are all sweet, the lady who cleans your teeth is gentle and thorough, and Dr. Saiki chats like a family friend after he examines your teeth for himself while explaining what he sees. Go for yourself and there is no way you will be disappointed!

They make you feel very welcome and comfortable, Doctor Saiki and staff have good customer service with all their patients, and most of all Doctor Saiki really cares about your needs as his patient, highly recommended!!!

Faith F. from Fallbrook, CA (Source: Yelp)


Dr. Saiki has been my families’ dentist since before I was born (29 years), back when he was located off of Oceanside Blvd. He is more than a dentist he is practically family! He always makes sure more than anything, he never causes any pain to you which is amazing. His staff is so sweet as well to include, Veronica and Lana who have been there for years! Again, this place is more than a dentist it’s like a family! We’ve recommended him plenty of times, if you go to him you won’t be disappointed!!! Thank you for all you’ve done for us!!

Chris G. from Oceanside, CA (Source: Yelp)


My family and I have been coming to Dr Saiki for many years now and we obviously prefer the service and care that he and his team provide. Everyone is very friendly and you will truly feel valued when you visit.  They are conveniently located near Tri City Hospital right off the 78 freeway in a quiet office space. I strongly recommend Dr Saiki as I know that my teeth and those of my wife and children are safely in his care!

Karen E. from Irvine, CA (Source: Yelp)


Stop you’ve found MR RIGHT in the crowded world of dentists in this area. They say that honesty and trust between two people is what it is all about. Well Dr. Saiki has it all – not only outstanding dental knowledge and talents but also god-given integrity and truly great character. He explained everything to me in the most straightforward manner and truly took the time to look at my situation and respond to all my questions and concerns. I interviewed many dentists before arriving at Dr, Saiki;s office so I can truly say that he is one of a kind, and I am thankful to have found him

The staff are always so nice and go out of their way for me and my family, they are awesome. And Dr. Saiki really takes the time to listen and makes me feel really comfortable. Not much of a dentist fan, but they sure did change my mind!! Thanks again for taking care of my family and my sister who has special needs!!

Patricia F. from Oceanside, CA (Source: Yelp)


Dr. Saiki has been our family dentist for the past 12 years.  We have been very pleased with the service we continue to receive each time we visit.  He has an outstanding staff that is friendly, and welcoming as well as efficient and professional.  I have recommended Dr. Saiki to several of my friends and family members who have now become his patients.  If you are currently looking for a great dentist please considered Dr. Saiki.  I am confident that you will be more than satisfied with your patient care.
