I'm not entirely sure where to direct this review, but I'm posting it here because I was a genuinely happy patient of Wellspring from 2021 until I moved out of Brooklyn. After relocating, I continued care at one of their Manhattan locations (East 30s) for about two years without issue. However, things took a very concerning turn in spring 2025. The day before my scheduled 6-month checkup, I received a text FROM WELLSPRING telling me they had "moved" and to report to a new address. When I arrived, I found myself at a completely different dental office -- unfamiliar staff, unfamiliar dentist, and no indication that this was no longer Wellspring - aside from all the signs and branding which revealed otherwise. I had never been notified that my original office had closed, that my providers were gone, or that my care had been transferred elsewhere. I only learned what had happened after questioning the staff and calling my original Brooklyn location. Apparently, the practice had closed and my records were transferred to another office without my knowledge or consent. What's especially frustrating is that Wellspring has (or had) other Manhattan locations -- including one closer to both my work and home -- yet I was never given the option to continue care within their network. I ultimately found the 57th Street location myself and went there for about a year. Now, the same exact thing has happened AGAIN! Ahead of my upcoming appointment, I received a reminder -- not from Wellspring -- but from yet another completely RANDOM dental office I have never heard of. When I called the number listed for the 57th Street Wellspring location, it routed me directly to this new office rather than anyone at Wellspring. That's when I learned that location had also closed. Twice in one year, Wellspring has transferred me to entirely new dental practices without any clear communication, consent, or choice. My records were sent elsewhere without my approval, and I was simply expected to show up and continue care as if nothing had changed. When I contacted this original Brooklyn office to raise these concerns, I was told: "this isn't on us -- the new office was responsible for notifying patients." However, neither new office provided any meaningful notice. In both cases, communication was misleading at best (e.g., implying a "move" rather than a closure and transfer), and at worst, nonexistent. This experience has been incredibly disorienting and disappointing. Patients not only take time to select medical/dental providers based on locations convenient to their work/home as well as based on reviews and past customer experiences - but they also spend time and money building trust and relationships with their providers. To have that continuity and their choice in providers/locations abruptly disrupted-- twice -- without transparency or basic communication is unacceptable. THIS IS ON WELLSPRING - NOT THE NEW LOCATIONS. Though I've also no interest in staying on with the new clinic either. Not good business practice for either! I don't understand why this process is being handled this way, or why patients aren't given the courtesy of clear information and the ability to make informed choices about their care. So - be warned - if this Brooklyn location has to close for some reason - gird your loins because they won't tell you and they'll just pawn you off on whomever they make a deal with and won't bat an eye. What an incredibly dehumanizing and maddening experience overall -not once - BUT TWICE. I'm eternally grateful my gynecologist's office respected me enough not to treat me like this when mine retired! read more

I'm usually nervous going to new dentist officies, but this was a great experience! Everyone was super friendly and nothing felt rushed. Dr. Zientz was very attentive and took time to explain everything and listen to my concerns. And they give you a cute goodie bag with a mug as a new patient! I had a great experience and would recommend this practice. read more

Waited for two months for a dentist appointment just for me to show up and tell me it was canceled. No notification, no phone call. Then the army of gaslighting deadeye zombies behind the counter tries to blame it on me. DONT GO TO THIS PLACE IF YOU ARE A NEW PATIENT read more

I'm 32 y/o and never had a cavity. I said I don't want a check-up X-Ray and the hygienist and nurse assistant flipped out on me. It felt downright intimidating and there was no respect for body autonomy. I'm coming here to get my teeth cleaned, and I'm under no obligation to get preventative X-Rays every year. But of course they get more $ with that. I hope the hygienist and nurse (who were initially unable to respect my request of no X-Ray) learn that every individual has autonomy over their own bodies. It's a baseline of respect and it's scary when health becomes so medicalized that people get intimidated into procedures. 2) their membership system is scammy, and they kept it running into the next year when I had clearly told them I wanted it to stop. 3) the hygienist did a good teeth cleaning, and the dentists are very personable. read more

Beware of these people. I went to Wellspring several times from 2017-2019 with the last treatment being late 2019 just before the Covid pandemic started. Office is nice enough and clean, location convenient to my home, and decent availability on Saturdays so I don't have to take time off work. After we went into lockdown and everyone was still wearing masks and terrified of getting the disease, the office called me at least a dozen times to schedule followup appointments, but I told them I left the city for the time being and would reach out when ready/comfortable to resume routine cleanings. The calls continued anyway, but I didn't mind, and never once did anyone mention that there was a balance due on my account. Fast forward 3 years and they somehow decided that I owe them $73 from back in 2019. I have no way of disputing, I don't have the same dental insurance company, nor do I even remember specifically what services they provided back then. They sent me to a COLLECTIONS AGENCY over this out-of-the-blue $73 bill. I paid the bill to make it go away, but I'm furious that they operated this way and intend to tell everyone I know in Cobble Hill to steer clear of these people. Only reason I'm giving them 2 stars is because the actual dental work and bedside manor was fine- but these billing practices are disgusting and no way to run a dental practice in a family neighborhood. Comments from others about them upcharging and selling other services is true, but didn't bother me a ton and I bought half the stuff they pushed on me anyway - but they clearly don't value their patients if this is how they run things. Good riddance. read more

I cannot recommend Wellspring enough - from the second you walk in until the second you leave, the front desk staff, hygienist and dentist are so human and gentle. Dr Zientz did a great job with reassurance prior to my procedure and knocked it out of the park with 0 pain. 10/10, thank you for a great experience! read more

New patient appointment today. The front desk du was hospitable and helpful before and after the appointment. Hygienist Jeanelle was careful and considerate, and we also had a nice chat while she worked on my teeth. I appreciate her a lot. Dr. Claason came in at the end, and he and Jeanelle walked me through their recommendation and answered my questions. It was a solid visit, but what separated them from the office I left to come and try Wellspring was the friendly staff, the considerate medical conversation, and the general sense of being cared for where my health was concerned. Thanks, Wellspring, BK. read more

Great dentist, I did Invisalign and super happy with the result ! Hygienist is the best

Let me first say that I pretty much never write reviews. If I were to have a bad experience at a restaurant or something, I'd probably just move on and not spread negative energy. Whenever I have a positive experience, I'll generally assume others did as well, and they can handle giving the praise. But in this case, I'm making a special exception because this was a special experience. I could probably write an essay-length review listing all of the positives from my visit to Wellspring Dental in Brooklyn yesterday, but I will try my best to maintain brevity and tell you what you want to know, which I'm sure is: did I like them and would I recommend them? Yes and yes. A little background: I have always had anxiety about dentist visits, ever since I was young. Before yesterday, I had not been to see a dentist in a very long time (years) -- due to this anxiety, as well as the pandemic, and a mouthful of other reasons, etc etc. I was admittedly extremely anxious as I walked into the office for my appointment. From the moment I entered, I noticed the place was very nice and clean, and the receptionist Emma was warm, welcoming, helpful and informative. After almost no wait time, I was seen by the hygienist Janelle. I explained to her my "story" and rattled off my laundry list of fears and anxieties. I am not exaggerating when I say that I was never once made to feel guilty or ashamed about my prolonged absence from the dentist's chair. Instead, Janelle put me at complete ease and did a brilliant job of keeping me informed about what we were doing, every step of the way. In terms of the cleaning -- Janelle is a dental DaVinci. There is a reason they call it the dental arts, and she is a master. When we looked at the photos she took before & after her work, they looked like two mouths from completely different human beings. After the cleaning, I was seen by Dr. Claassen, whose professional demeanor and caring personality perfectly complimented Janelle's. He was exceptional at explaining everything we'd done, everything we should do next, and how my dental health and aesthetic goals were attainable. I joked with them that they were doubling as dentists + therapists (healing my mouth & mind) -- but thinking back on the experience, there is so much truth to that. As I said, I could go on and on about these two, and this place -- but the bottom line is that I walked in terrified, and walked out hopeful and happy. And I think that says it all. Highest possible recommendation. read more

Best dentist experience I've had in almost 50 years: friendly, organized, they make extra effort to tell you what they're doing and why, taking pictures of your teeth, not just x-rays, and explaining what's going on. very empowering. Bravo. read more

I could not have asked for a better experience at Wellspring Dental! Phillip and the rest of his staff and incredibly sweet and truly care about the people that come in for dental work. I used to be pretty self-conscience about my smile. I had several silver fillings and chipped teeth. Phillip helped me replace my fillings from silver to white and fixed my chipped front teeth! I've received so many compliments on my smile and it's all because of Wellspring. Also, as an added plus, they have extremely flexible appointments and have weekend availability! Lastly, I recently moved to the west coast despite having a wisdom teeth extraction pending with Wellspring. Wellspring went above and beyond to make sure my insurance would work in California and provided a referral for the extraction. I am now sitting on my couch recovering from my extraction this morning. Everything went smoothly. Thanks so much for everything Wellspring! Y'all are the best. read more

Brittany is the BEST!!! I had been going to another practice for years and really only stayed with that dentist because of how amazing Brittany was. When she moved to Wellspring, I followed right along. She is fun, positive, and always does a wonderful job. It's clear she is passionate about her work and truly cares about her patients' teeth. I've always left smiling, because of the lovely interaction and the clean white teeth! :) I had my first appointment at Wellspring a few weeks ago and it seems I've finally found a positive experience all around. The staff at the front desk was very friendly and made me feel welcome. Dr. Claassen was incredibly pleasant, calmly taking the time to explain every detail and fully answer any of my questions. I left Wellspring with clean teeth, an informed understanding of what I should (and shouldn't) be doing to maintain those clean teeth, and felt my whole end to end experience had been with genuine, nice people. I'm very happy with my new practice. read more

I visited the office for the first time last week for a cleaning and check-up. I had been unsatisfied with the last couple dentists I had and was hoping to find someone I could trust. (A dentist is like a mechanic, you've got to have one you can trust or you'll just end up paying for unnecessary repairs.) Everything about my experience here was great. The cleaning was thorough and friendly (and very informative). The consultation was not rushed and the doctor spent a good deal of time not just explaining what I needed, but what I might need but not yet (or perhaps never) and things to keep an eye on. He explained everything in more detail than any other dentist I've ever had. And I appreciated all of it. The front desk staff were also fantastic. Friendly, mellow, good senses of humor, and totally accommodating to different needs. They even gave me a parting gift of a Wellspring coffee mug and toothbrush - which was a first. Not since you were little and the dentist ironically gave you candy for being good will you feel so pleased leaving the dentist. read more

By far my favorite dentist office I've gone to in the city. I've been going for a little over the year. The entire team is friendly, funny, easy to talk to, and extremely thoughtful/attentive teeth cleaners. Brittany is the best. Her and Dr. Z give me just the right level of crap for not flossing and not using the fluoride paste I'm supposed to - I walk away feeling feel like "Mike, do better," rather than like I committed murder, compared to previous dentists. I can't recommend enough! -Mike read more

My family has been seeing Dr. Zeintz at wellspring dental for several years now. I've gotten Invisalign there, had countless cleanings, and my children have had wonderful experiences there too. We are very grateful to have found Wellspring Dental and very much appreciate the whole team there . Definitely recommend! read more

The combinations of expertise and kindness, thoroughness with a gentle touch, efficiency with ease, all of this and so much more (i.e. state of the art equipped office) made for a dental practice I'm delighted to recommend. From the seamlessly smooth experience with the folks at the reception desk to the phenomenal hygienist (Britney) to Dr. Zientz himself, one word comes to mind: superb! read more

Wonderful staff, state of the art equipment and exceptional service. Chose this office based on reviews and was not disappointed.

Great dentist. Really nice team. Reasonable prices. Clean offices. Really like them.

The best experience I've had at a dental practice in years. All the staff are some welcoming and professional, and were so great with my little 2-year old daughter -- who was like a different child from the one one visited a previous dentist. Dr Zientz is knowledgeable with a casual, friendly bedside manner. He took the time with each of my family to walk through x-rays in detail and answer any questions. Brittany, the dental hygienist, gave me the most thorough cleaning I think my teeth have ever had, while ensuring I was as comfortable as possible. A great experience from making an initial appointment with Lisa to leaving with brighter smiles! The practice is clean, modern, and very much of the neighborhood. Myself, my wife, and daughter all had a wonderful experience, and would highly recommend to others. read more

We've been residents in the city for decades and Wellspring is the best care we've received in dental or general medicine. Everyone takes such amazing care of us and there staff is second to none. Brittany has been especially great to work and always makes us feel like we're in incredible hands. Thx Wellspring! read more

This was the most positive experience I have ever had at a dentists office! Brittany my dental hygienist was thorough and communicative and just all around incredible! She let me know what she was doing and what each part of the cleaning was for. She even communicated when I would feel pressure or a sensitive spot and reminded me to take a deep breath. I felt so taken care of and that I was in a safe space. Two years ago I had a bad dental experience at another dentists office and haven't been to one since. I shared with Brittany and Dr. Zientz my anxiety around going to the dentist and they both held my feelings with care and understanding. They assured me that I was in good hands and totally put me at ease about an experience I had been avoiding for two years because of fear! The check in process was easy and quick and their text notifications were so helpful leading up to my appointment. When Dr. Zientz entered he asked me a bit about myself (which I had never experienced in a dentists office!) he seemed interested in getting to know me as his patient which felt really meaningful and so unlike any other dental office I have been to. Part of the process is taking photos of your teeth and then before having you lay back in the chair, they show you on the screen what they are going to be looking at and what spots they are paying attention to. I mean how cool is that!?? I can not express how positive and lovely this entire experience was. Now that I have found this incredible dentist, I finally feel at ease with my dental health. My experience at Wellspring Dental has changed my perspective on dentists and I am bummed I have to wait 6 months to see them again! read more

Wellspring Dental - Brooklyn - They even sent me home with a little care package!!! - Cosmetic Dentists Near Me - Brooklyn, New York

Hands down, best dental experience I have ever had. The dental hygienist was so warm and thorough, the dentist took his time examining my teeth and answering all my questions. The space is very nice and clean. I actually look forward to going back! read more

Wonderful! Patient, kind and excellent work! I am a huge fan of this practice. Thanks!

Truly the nicest dentist/medical environment I have ever been in. Everyone there, from the front desk staff to the hygienist to the dentist are all so welcoming, warm, and genuinely seem to be looking out for you. Highly recommend!! read more

Dr. Zientz is great! He's both professional and relatable -- and he's a great communicator, which is key. I recently saw him for a twice-a-year visit, and I was more than pleased with my cleaning and how well Dr. Z explained, part by part, what was going on with my (mostly cavity-free) teeth. I've bounced between a couple hectic dentist's offices since moving to NY four years ago, but my experience with Wellspring -- from scheduling the appointment to climbing into the chair -- was by far the best of the bunch. I think I've found my Brooklyn dentist! read more

I'm several months into an Invisalign treatment with Dr. Zientz and can't say enough nice things. I'll break it down for you in the 4 main areas that have been deal breakers in my past dental experiences: Price: I had 3 other Invisalign consultations with other dentists and Dr. Z was easily the most affordable. His payment plan is wallet friendly and he is very honest about cost and necessity. I'm a patient that occasionally has to say "Is this going to kill me? If not, can I do it/pay for it later?" and Dr. Z is very non-judgemental and honest in advising the best treatment plan for my mouth and my wallet. Experience: Dr. Z is so thorough, friendly and accessible. I initially came in for an Invisalign consultation and he noticed a cavity too. Please note, I called out this cavity to a mediocre Brooklyn dentist (couch cough iSmile) and they told me it didn't exist! Dr. Z took care of it and got me started on Invisalign as well. My dog ate one of my Invisalign trays and Dr. Z was also quick to return my call and resolve the issue. Appointments/Waiting Room life: Never had an issue getting an appointment or with wait times here. If you need a Saturday appointment, you can schedule one! It's amazing! Location/Office: The office is clean, modern, very calm and chill. The location also cannot be beat. Go to Dr Z and take care of that dental issue you've been putting off forever then reward yourself with a trip to Court Street Grocers. read more

I really liked my old dentist but I moved and wasn't willing to make an hour commute for a cleaning. I found Wellspring and so pleased to have a new great dental office. Lisa at the front desk made scheduling an appointment so easy (she actually reached out when an earlier time opened) and she was very pleasant when I arrived! Dr. Zientz was nice, professional and busted out a few dentist jokes. He was great about explaining what he was doing and what he saw. I'll be back and recommending to friends in BK! read more

Best dental exam I've had in 70 years. Office staff and dental staff are superb. Have already urged my wife and daughter to see Dr. Zientz. read more

Place is great. Modern vibes, forms are filled out on an iPad, some fields are actually prepopulated by the extremely competent staff. Appointment happened on time. Dentist is an extremely tall young man, with an excellent bedside manner. Good music and streaming video options to distract. But he tells amusing stories while efficiently doing his job. Great neighborhood find. read more

I have delayed making an appointment for a couple of years. Wish I hadn't. Janelle was super gentle but thorough in cleaning. The dentist explained everything that I need to have done - starting with what is most urgent. I recently changed insurance. I'm not sure if this changed the cost, but my quote is about half of what I paid at my last dentist for similar services. I would highly recommend Wellspring. read more

My husband and I've been seeing Dr.Mitch for a few years and we love him! He was able to see my daughter for an urgent matter and he was so great! We highly recommend wellspring dental! read more

Great experience. Very nice staff and doctor. I've been going to another dentist for years and when I complained of jaw pain the doctor dismissed it. Dr Classsen took his time to look at my jaw and perform tests to get at the root cause. I have no resolution yet, but it is good to have someone listen and take the time to investigate. The hygienist was nice and gentle. They both explained everything and even took photos of my mouth so they could show me what they saw. The office is also very modern and comfortable! The music is great. Overall, welcome modern dentistry to Carroll Gardens! read more

Always a great experience here! The whole staff is extremely friendly, timely, and knowledgeable. Would highly recommend!

I came in to ask a few questions and the front desk staff gave me such a nasty face right when I walked in. The man at the front desk had such a rude demeanor. I was so thrown off. read more

Lisa in the office is friendly, accommodating and communicative. The office is clean, offers beverages and has a calm atmosphere. I had zero wait time! Dr. Zeintz was friendly, informative, helpful and put me at ease after 3+ years of not getting a teeth cleaning. We did a full set of x-rays, which he then explained to me, and then a thorough cleaning. Overall a fantastic experience. My only hesitancy in giving a glowing review is that everyone will start going and it will be hard to get an appt! :-) Also, you leave with a swag bag. Hard to beat. read more

I liked going to this dentist which, as someone who is afraid of going to the dentist, is a big deal.

This is a fine dentist if you don't care about your money. But I do and I pay very close attention to it because I have to. This was my dentist for a few years and from the very first appointment the billing practices have been shady. I would schedule appointments for annual and biannual cleanings, X rays, i.e. preventative services that were supposed to be 100% covered by insurance, yet I would always get an invoice for the appt with varying random amounts due. Sure, they up sell the fluoride application for an extra $20 every cleaning and I am happy to pay charges I am made transparently aware of & extra non-covered services that I *elect with full consent.* But, there would always be a balance specifically remaining from the services that were supposed to be 100% covered. I do know there are multiple ways/codes offices can bill for the same service so IDK how/why they billed, but end of the day, I have paid hundreds in these leftover random balances. Every year/half a year I was in the chair, I would ask the staff to confirm multiple times that they weren't doing anything outside the regular preventative 100% covered schedule of insurance services. They would assure me that was the case. Then weeks/months later the bill would come for the random balance. When I tell the billing admin "this appointment was for preventative services 100% covered, and I verified that multiple times before the services were given" I never once received a good explanation. Their response is not to try to work it out with insurance but to just keep insisting you pay this random unexplained balance. They also tried to sell me custom mouth guards (of course completely NOT covered by insurance) multiple times and I never could afford it. One appointment, after I had told the dentist I did not want to pursue the mouth guard at that time, I get a call asking me when I want to schedule the mouth guard fitting. I had to make it crystal clear basically every time I was there that I could not afford a custom, fully-not-covered-by-insurance, mouth guard. As I asked around my husband and some co workers who also went to the same dentist I found that they were being pushed to go for the mouth guard as well. read more

Super friendly staff, wait time was short, and office was clean! I felt like the staff truly cared about my experience and my teeth! Definitely recommend! read more

Dr. Zientz and his staff are the nicest people! The office is clean and pleasant, Doc Zientz is calm and cool and very reassuring. He has all the latest technology and knows how to use it. The best dentist experience Ive ever had. Yes, really. He took the time to explain what he will be doing, asks frequently how your doing during the procedure, very attentive and caring. I scheduled more work and he and his staff dealt with my curmudgeonly insurance company. If you need a dentist or want to change your dentist, I highly recommend Wellspring Dental. read more

Going to the dentist has always been terrifying to me. It makes me sweat. Not the case with Dr. Zientz. He explained the ins and outs of everything that was happening and was super calming, professional, nice, and understanding. I had a wonderful experience -- and that's *not* what I was expecting after not going to the dentist for 6 years. I got two fillings, the whole X-ray deal, and a cleaning. Everything was painless and smooth. For me, Wellspring Dental was a great reintroduction to the world of actually going to the dentist. Also a great location in a great neighborhood. read more
