Such a memorable trip to the dentist for my little one- all thanks to Dr. David Delong & his wonderful staff!! While my daughter didn't have terrible previous dental experiences, she never got into the groove of things when it came down to actually coming in. With her permanent incisors coming in & one specific baby tooth seeming like it wasn't doing any budging, I reacted logically by FREAKING OUT!! Lmao. I reached out to the office and was able to schedule something in fairly quickly. Thank you, Indi, for being so professional, kind, and informative- you truly are a wiz at what you do! Fast forward to the visit: My daughter and I were immediately greeted with Indi's warm smile. I can't think of a better first person to meet & interact with upon arrival. The vibes of the office was warm, welcoming, and immediately put me at ease. Forms were provided and in no time at all, we were brought back. Shout out to the hygienist, Marrysa!! Thank you for taking the time to allow for my toddler to warm up. I appreciated the patience you showed and the extra efforts you made to walk my child through the entire process/visit. Thank you Cathy for chiming in with the assist and making the appointment seamless. Your lovely smile and calm demeanor gave my child a little extra pep in her step. Lastly, thank you Dr. Delong for the prompt evaluation & putting this mama's nerves at ease. The eval was quick but it did not compromise the quality in any shape or form. For those of you in need of a gentle doc, he is THE MAN! 5/5 stars. I honestly didn't expect for the appointment to go so well. Check out was just as fast as check in! Indi was proactive in covering the next scheduled cleaning and the other girls quickly put together a goodie bag. My child left asking when she would be back. Lol. While explaining to her that our next visit would be in 6 months she eagerly responded with wanting to come back "EVERY WEEK"!!! If that doesn't speak volumes, idk what would. Thank you Dr. D Delong & thank you ladies- customer service and patient interaction doesn't get any better than this! read more

See all

Dr. Toy is an awesome dentist, and lives up perfectly to dr delong's work. Everyone is extremely kind patient caring and professional! Had my wisdom teeth out here and fillings and deep cleanings and all went really well. Dentist took out my wisdom tooth while I was awake and I didn't even realize when it came out. They're all really good at what they do! read more

Dr DeLong was very good. Maybe his best decision was to sell his practice to Dr Toy. Now, let me tell you about Dr Toy. #1 - I am not a fan of sitting in a dental chair, I really don't like it. Dr DeLong was real good working with me. Dr Toy, om my very 1st visit to extract a tooth, was STELLAR. # 2 Novacain shot, didn't even feel a pinch. Dr Toy has "the touch". #3 tooth extraction was very smooth, didn't feel anything, no yanking, no pulling, just aster 10/15 minutes, "Ok, we are done here", yes, it was that simple, easy & pain-free. #4 follow up appointment was terrific. Stitches removed, everything all healed up perfectly, I couldn't be happier. Thanks Dr Delong for handing the keys over to a great guy! I highly recommend Dr Toy!​ read more

Dr Delong is gentle and listens to his patients, as well as explain what work and how will be done on your visit. Walking into his office has a quaint and cozy feeling, and the his team greets everyone Scott come in, should they be near the front desk Dr Delong set me up with Invisalign- very easy and painless !! He has been our go to dentist for at least 10 yrs( could be more!!) and we have been very happy over the years read more

Good , honest doctor , gives real advise and doesn't try to Upsell you BS like most dentists . Highly recommend read more

I went to Dr. Delong for over 20 years and was taken advantage by his unnecessary services so he can make money from me and my dental insurance companies. It took me a long time to realize what he was doing; so, I left and went to different dentists, and they all confirmed the bad jobs he did with my teeth. One of them told me he wrote an email complained to Dr. Delong about his unethical services and bad work on my teeth. I went to a different dentist because of the change of my job location and again, this dentist laughed saying that how the bad work Dr. Delong implanted on my teeth, and now he is the one that harvested the profit from fixing them. It took me a while to realize that I was taken advantage by Dr. Delong because a few times when I was leaving Dr. Delong, one of the ladies in the office kept on telling me that Dr. Delong has 5 kids and that he has to take care of them. So that why he took advantage of me and my dental insurance companies for all those years? I am now still paying a lot of money and time to fix his bad, unethical works. SUCH A SHAME! I don't like to write bad review, but it is necessary as people need to know how bad this place is and should to avoid this place at any cost. read more

I've been going to Dr. Delong for nearly 30 years and I can't say enough good things about him. He is skillful, caring and creative when comes to solving dental issues. I totally trust Dr. Delong. read more

My husband and I have been patients of Dr. Delong since the mid-1980s and no that is not a typo :-) He is an amazing dentist with the most up to date equipment, and a GREAT chair-side-manor. Very gentle and he never nags at you to floss your teeth or if he does, he is very kind about it. Also his hygienists and dental assistances have all be beyond amazing !!! Again, gentle and making sure you are comfortable and everyone in his office and Dr. Delong have a kind and fun personality to boot. We are 100 percent satisfied - so satisfied in fact that we have now retired and live 2 hours away from his office and we still go to him - which speaks volumes... Smile big and beautiful - that's my motto ! And thanks to Dr. D. we do !!! Cheers !!! m. read more

Dr. Delong is compassionate, caring and has always treated me with respect. He works with you to figure out the best options for the most beautiful smile, least amount of pain physically and to your wallet. If you've ever had a painful experience with a dentist, please give Dr. Delong and his team a chance to give you a positive one. They are the best in the west! read more

David R Delong, DDS - Cosmetic Dentists Near Me - Santa Clara, California

Been coming here for a decade; really nice group of people and im happy for them to have my business.

I've been going to Dr. DeLong for years and take my kids there too. Everyone in the office is friendly, kind, and professional. More importantly, I trust in Dr. DeLong's advice and care of our teeth. He always takes the time to explain and is conservative about recommending treatment. Couldn't ask for a better dentist! read more

Dr. Delong and his staff are the most friendly, caring, and welcoming committee ever to exist in the Dental Industry. Every individual who enters the office is greeted warmly and is asked how they're doing, how their weekend was, etc. 5/5 Dr. Delong and his staff know exactly what to do and try their best to keep the pain at its lowest percentage. Thank you, Dr. Delong! Thank you, Staff! My teeth thank you! :) read more

Dr. DeLong is a fantastic dentist. I was very satisfied with the care that he and his staff provided. I felt that he truly cared about my wellbeing, gave me straightforward answers, and excellent care. I would highly recommend Dr. DeLong to my friends or family members who needed dental care! read more

Dr. Delong has been my dentist for about 25 years. He's the best!!! I always look forward to seeing him & everyone else at the office. So friendly & cheerful. read more

The previous reviews are SPOT ON. Dr. DeLong is a brilliant man. He explains everything in laymans terms, which for someone like me (who likes to know whats going on and why) is VERY calming. I too was referred to him, and can say it was worth the trip. Did I mention that I came from Sao Paulo, Brazil to visit him, and paid cash? I kid you not. He also has a TV and little camera that fits in your mouth to show you what is going on and why. WHY ISN'T THIS AN INDUSTRY STANDARD? It's absolutely brilliant, as is Dr. DeLong. I promise you, this won't be the last time I fly 15+ hours to visit Dr. DeLong. I can certainly attest to the fact that Dr. DeLong is a WORLD-CLASS dentist. read more

I had another teeth cleaning with Meg and had another positive experience with Dr. Delong and his staff! I look forward to seeing them again in 6 months. read more

dr. delong is an amazing dentist. right from the start, you can tell he is genuine and really cares to get to know you. he has an intraoral camera and takes pictures of the teeth, so we can see what he sees. i have never seen this before and i think all dentists should have this, not that i plan on seeing another anyways. i like that he has this because when he sees something, he lets you know right away. he doesn't try to push anything on you, like other dentists out there. he shows your the pictures and is honest with how severe it is or how soon we need to change it. i love that he informs me and lets me do all the decision making. dr. delong did my cleaning and it was amazing. we had small conversations here and there, in between the teeth scraping and thats when i knew he was a keeper. he shared stories and asked about my life and that is amazing. other offices just clean clean clean and say thank you. they don't really care to get to know you on a more personal level. i usually hate dentists, i really do, but the office puts me at ease. they aren't like any other offices where they are timid or don't talk much. they seem to mesh well with each other and for them it works. i can't wait for my next 6 months cleaning. if you're looking for a dentist, look no further ... dr. delong is the man for you! read more

Dr. DeLong is a great dentist and a great human, too. He helped me with some intensive oral health care and did such a wonderful job helping me get my smile back while I recovered from surgery, etc. The office staff is fabulous. Kind, thorough, professional, and so helpful! What a great team! I HIGHLY recommend Dr. Delong and his care team for every kind of smile. Oh, and you get lip balm, tooth paste, floss and a toothbrush when you get your teeth cleaned! read more

My wife & I have been patients of Dr. David DeLong since moving to Santa Clara in 1994. We both love the work of Dr. DeLong and his staff and we enthusiastically recommend them to anyone seeking high-quality dental care. About 17 years ago Dr. DeLong explained that both of us would benefit from dental veneers and we agreed. Those veneers look wonderful and have been trouble free the entire 23 years!! We are grateful to Dr. DeLong and his staff. read more

I know this isn't something you normally hear about going to the dentist, but my experience was truly amazing! Hear me out - I promise, I'm not nuts! When I called Dr. DeLong's office, I was terrified. After all, one of my fillings broke while I was flossing, and I couldn't get hold of my regular dentist for two days. Also, with the COVID outbreak going on, I wasn't exactly champing at the bit to go to a dentist office. Anxiously, I researched dentists and after seeing the great reviews, decided upon Dr. DeLong. I got an appointment with him and went to the office, not knowing what to expect. Thank goodness, they have great protocols for dealing with COVID: You park your car, call the front desk, a nice man with a pulse oximeter comes out, greets you, and takes your temperature, and they make sure the coast is clear before you enter the building. That made me feel so much less scared! When I got in, Cathy (one of the dental hygienists) made me feel so welcomed and relaxed and the minute I met Dr. DeLong, I felt at ease. He's so nice and gentle, and is very patient with folks who are scared of dental needles (like I am!). He and Cathy worked so well together while getting my tooth fixed up (and without pain). They were so amazing that I came back and got a cleaning with their other great dental hygienist, Meg! Anyway, that's my long-winded way of saying that this is is a great dental office. I've already booked my next cleaning! read more

Dr. DeLong and his staff are the BEST in the South Bay. They always use the most modern equipment and Dr. DeLong does excellent work. Meg is an excellent hygienist as well! Arlene at the front desk always greets patients with a big smile and handles all of the insurance stuff expertly! I have been going to Dr. DeLong for 28 years and have referred many other friends and family to him over that time. read more

Love my dentist. He is a painless dentist. Nice staff look no further for a great dental team.

I was a bit nervous to find a new dentist when I moved to California, but have to say I am so pleased with David Delong and the whole staff!!! Definitely recommend this dentist! read more

I've been going to Dr. DeLong's office for years. He does wonderful work and his staff is the best. While I can't say I look forward to going to the dentist, Dr. DeLong has always made me feel comfortable and his staff is always welcoming. Highly recommended! read more

I have been going to Dr Delong for many years. He is by far the best dentist I have ever had! I live some miles away but he is worth the long drive. As far as major work is concerned He is very conservative with his care and will do only what really needs to be done. Meg is a superb hygienist and Arleen could not be more pleasant. I recently met Kathy, his assistant, and she is efficient, caring and an asset to his staff. Office is lovely, discounts are given for full payments. Five stars is not enough for Dr Delong and his staff! read more

Dr DeLong saved the day again. Forty year old bonding broke off of my front tooth and I was able to get an appointment immediately and he rebuilt my tooth to perfection. I appreciate the fact that Dr DeLong will do what it takes to get the best results. He never rushes just to get it done. He also has the best team ever! read more

Dr. DeLong has been taking care of my dental problems for at least 20 years. He is gentle, explains everything clearly, and you really feel that he cares. You can even feel it in his touch. His staff has been with him for many years and they are wonderful too. They always have a smile and remember me. I highly recommend Dr. DeLong!! read more

Wow what a great Denist and a great staff. They make you feel like family. And always willing to work weekends and night. Couldn't find a better place to get your dental work done. Thank you very much. Doctor and staff. Mr. Mrs. Jackson read more

I've only visited him once but I'll add that I really like how my first appointment - a routine cleaning - went earlier this week. Dr. DeLong seems like a knowledgeable dentist and a really good guy, and explained things honestly without aggressively upselling me on expensive optional procedures (which is why I left my last dentist). read more

Dr. Delong & his team are the greatest, i am very happy with comfort the office has shown me, they our always happy, and considerate to my needs. They are good listeners and always try to accomodate me. I must say he is painless and very gentle touch.... i highly recommend his office, especially if you had a bad experience before! read more

Comfort & Finesse ! Yes I'm talking about my Dentist and his practice. I can honestly tell you I look forward to my appointments. Whether it's my 6 month check up or a teeth cleaning, this is my dental therapy. Team DeLong is ultra attentive & super friendly. Appointments are a welcome respite from my daily grind. Pearly whites & positive reinforcement from the entire staff motivates you to be in the daily flossing zone. Dr. DeLong clearly is on top of his game, incorporating the latest in dental innovation. Meg is their Dental hygienist extraordinaire and Arlene is the finest front office concierge. Thank goodness for the DDC(DeLong Dental Center). read more

Five stars for Dr DeLong and his staff. The quality of care is excellent, and they've been very helpful sorting out issues with our insurance providers over the years. read more

I'm very fussy about dentists - I was recommended Dr Delong through another online community. I have to say I have been most impressed by his professionalism. Having worked at one stage of my life for the ADA I am very fussy about who pokes around in my teeth. Having had some bad experiences as a child made me even extra fussy who I sent my children to. He is wonderful, as is his staff. They are the best! read more

Dr. Delong has been my dentist for 20+ years. That should say it all! He is the best dentist I have ever been to. His professionalism and the quality of his work are exemplary. Not only that but, his staff reflects his high standards. read more

Great dentist, very honest and takes care of you. Staff is very friendly, fees are decent so.

Dr. David Delong is the BEST dentist I have ever had the greatest luck to trust as a patient at his practice in Santa Clara. His staff members are wonderfully kind and top professionals, and I have to give a shout out to Meg and Arlene! Best of all, Dr. Delong is so knowledgeable, calm, and takes the time to explain his procedures as well as surround himself with expert specialists who think the world of him. My colleague at work, Karen, gave me the recommendation to visit Dr. Delong, and I am so very grateful. Even my son, who has dental fright, was surprised at the expert care he received. We are loyal Dr. Delong fans and proud of it! read more

Awesome dentist anyone can ever have! He's been my dentist since he took over this office. He is friendly, very knowledgeable & professional. The staff is also friendly and professional. They know you by name and is very welcoming the moment you walk into the door. This office is the reason why i LOVE going to the dentist! read more

My husband and I are new to the area and needed to find a dentist. After enjoying fantastic care by the same dentist for 35 years, we knew that our new dentist would have some tall shoes to fill! How fortunate we were to have been referred to Dr. DeLong by our former dentist. He and his entire staff are professional and value excellence in their work and patient interactions. Arlene at the front desk is organized, efficient and extremely friendly. We highly recommend Dr. DeLong and his staff! read more
