In my 77 years and many moves, I would guess I have seen at least a dozen dentists. I am so fortunate that I found Dr. Winterton when I am staying one place because no one else has been so kind, attentive, careful, and patient. He listens and remembers what you asked for. His confidence is comforting. His work is focused and thorough. The staff is obviously in sync with how he respects the patients. I am relieved knowing I have a great dentist. read more

Just saw Dr. Winterton to finish an implant supported crown. All went flawlessly...No adjustments, no discomfort, no issues. I'm very happy that Jim and his team are caring for our family of patients!! I hear nothing but praise from my former patients about his professionalism and quality of care. read more

What a wonderful experience at Dr Winterton's office this morning. I was seeing him during a surprise visit for us both actually! Saturday evening literally seconds before walking into a meeting at an event, I reached for a small handful of popcorn, chewed and thought I had bitten into a kernel, nope!! It was my back lower right crown now in my palm. My general dentist is also in the building and happened to be on Christmas vacation with his family. So he tags Dr James in to deal with any emergency cases on while he is away. They were able make an appt for me Tuesday am to get it reseated. She tells me wait for confirmation via text and asks for my cell number. Tuesday am comes around and Dr Winterton and team have me in and out within 30 mins. Crown seated, and a small adjustment and polishing after checking my bite. I'm thankful he was here during the Holidays to fill-in for me. His office and techs were really friendly, the lobby is super clean and modern too, see pics. And they were able to bill my insurance company for the quick fix. read more

James Winterton, DDS - Cosmetic Dentists Near Me - Newport Beach, California

See all

Dr Winterton cancelled his in-network relationship with Metlife Dental insurance. His letter said that there "could an increase in cost treatments" as an out-of-network provider. However, when I confronted him face-to-face, he said that the "costs would be about the same." We received a $295 bill for a teeth cleaning and xrays that would have been totally covered by Metlife. read more

Im a long time client, 20 + years, with Dr. helliwell before Dr. winterton took over. I had appnt on 10/7. I texted their chat system saying I would be 20 minutes late. I never heard back, when I arrived (30 minutes late) they said they never got my text because the server crashed and they would be unable to see me and will need to reschedule. No problem. Here's where things went south. On 10/11 I got a text saying I need to schedule appnt. When I texted 10/12 Kim texted me saying " we will not be rescheduling you for future appnts" and "we feel you would be happier somewhere else" I couldnt believe it, very rude, unapologetic and condescending. I have been with that office for so long, and to be treated like that... I felt completely abandoned. Shame on Kim. It takes months to see them, they need more help. read more

Dr. Winterton and the entire staff are great! I have received excellent care during routine check-ups as well as necessary dental work. Recently, Dr. Winterton performed some minor cosmetic work to improve my smile without charge! I recommend him to all my friends. read more

Been going here for the past 20+ years. Dr. Winterton is always so nice and helpful. Caitlin, Anne and Kim at the front desk are OUTSTANDING. Jill is retiring soon but she is such a light in that office. Feels like you're seeing family with every call or visit. I HATE seeing the dentist but love seeing those smiling and happy faces. read more

I liked this dentist at first because the actual dentist was present at my appointments. He missed one of my appointments and I knew he wouldn't be there so I just saw the tech to get cleaned. Then another appointment 6 months later was coming up that they said he would be present for when I booked 6 months in advance and he wasn't. They didn't call me to inform me he wouldn't be there after all either to give me a chance at rebooking to be seen by him. They have someone new at front desk the previous person always called. I left and didn't even go through with the cleaning. Complete waste of my time. That would be 1 full year my actual dentist didn't poke or look at my teeth himself and he was fully okay with that. No rescheduling for his absence or even a call to let me know. And to top it off they tell me it was a vacation before his kids went back to school. That's great and everything but when you have patients you have not personally seen in a years time you should want to see whats going on as a caring dentist. That's why there is a dentist and there are techs. Each time I've gone to the dentist anywhere else in the past the actual doctor looked into my mouth and poked around after the tech was done. It's rare to go a year with 2 appointments in that year and not actually see the dentist. -NH read more

Dr. Winterton is great, but unfortunately his front desk will lead you to believe that they've done their part. Triple check your insurance, because she will assume that you are in network, then later tell you that you are not and say oh well it's your responsibility. Yes, I understand responsibility and paid my part. I also don't appreciate being laughed at, very unprofessional and rude. Hope this is a teachable moment to not assume and not to laugh at someone who is trying to pay you. read more

Can not say enough about Dr. Winterton. I've had my teeth cleaned with him twice now and it's been such a pleasant experience. He's a very good dentist; honest and always gives you the truth without glazing or selling you on anything. Highly recommend. read more

Going to the dentist is nothing I look forward to, but Dr. Winterton has made it as pleasant as possible. I have been twice now and am very happy with the care and service provided. He was able to answer all my questions and provide great instruction on a few problem areas of my mouth. I highly recommend Dr. James Winterton and I will be back. read more

I just got a filling completed by Dr. Winterton, and I have to say that it was the easiest and most comfortable "dental experience" that I've ever had. I didn't feel a thing!! I can honestly say that Dr. Winterton puts his patients at complete ease, and is so great at what he does. I highly recommend him to anyone looking for a dentist. As an aside his staff was great too! read more

I went to Dr Winterton as a referral from a friend. I thought that he was very profession and put the care into my hands. Given my dental history I have tended to be more conservative with my teeth. After his initial exam, we discussed my options. There are still 1-2 teeth that could be filled but we are still watching as they are symptomatic. In July of this year, I had excrutiating pain in my mouth and jaw. He promptly diagnosed and referred me to an excellent endodontist for a root canal. Dr Winterton did an superb job fitting me for the post root canal crown. I also appreciated his integrity and honesty. I ended up paying him $80 extra for the crown, which he reimbursed me with a check in the mail. I have 2 kids, who were seeing a different dentist prior, that are regular clients of Dr Winterton. His staff are friendly and he is excellent with kids. He is a great physician and one that I will continue to see for my dental care. read more

Dr. Winterton and his staff really went above and beyond for me at my last visit. From when i first booked my appointment to my first visit the staff was very sweet and helpful. I haven't been to the dentist in a million years and I was nervous, but Dr. Winterton was so kind and genuine & he really made me feel more comfortable. Thank you for everything you guys did for me I really appreciate it! read more

Love this office! I have been dragging my feet to find a dentist in the area, since I moved here, that would match my high standards. I have found him!

I switched our family over to Dr. James L Winterton, DDS. in Jan of 2018 and it was the best thing I ever did!! Dr. Winterton is an excellent dentist, he is knowledgeable and performs beautiful dental work. Sincerely, I can not say enough about his ability. My husband cracked a tooth and needed a crown, he told me that he has never had a better experience, the fit was perfect! It's hard to find a great dentist who does excellent work and is honest in his practice but Dr. Winterton is both!!! I am so happy to have found this amazing dentist! read more

My husband and I and our 3 children (ages 12, 10, & 8) have been going to Dr Winterton for the bast couple years. We had only very positive experiences with him and his office staff. He is great with kids and they have even shown excitement about visiting the dentist. I would recommend Dr Winterton for a great family dentist. read more

After he scheduled me for an appointment at his Newport office, when I was finally seen I was told that my insurance was not accepted at that location. This is after I stood in the waiting room for 10 minutes while no one was there. I figured that I was on candid camera. Apparently not. After James made the mistake he didn't even tell me in person, apologize or try and work something out as a cash patient. His office is a mess and doesn't understand basic courtesy. read more

I went to Dr. Winterton for a crown on one of my molars that was experiencing both pain and sensitivity to hot and cold temperatures. Dr. Winterton was careful to explain all my options regarding treatment and was helpful in objectively answering my questions about what option might be right for me. I truly didn't feel "sold" (like I have at other dentists) or that he had an agenda as to what treatment was more lucrative for him. The procedure went excellent and the follow-up was thorough. The office is clean and the staff was very professional and helpful. I have already recommended Dr. Winterton to a co-worker and wouldn't hesitate to refer him again. read more
