Although to tell you the truth, I could have easily fallen asleep in that chair-one of the most comfortable chairs on the planet, I am sure. I have been a patient since 2008. I have moved around the country a lot for work - 9 states- and Dr. Benjamin and her team are the best that I have found in the U.S. I left the Bay Area in 2013 but Dr. Benjamin allowed me to continue to be a patient and I've traveled back twice a year for dental care except during Covid. I know that there are a lot of great people-and dentists- out there but Marina Tooth Fairy is right for me. I trust Dr. Benjamin. If you are looking for a wonderful team that you can trust and a place where you will feel comfortable, I strongly recommend making an appointment. I am confident that you won't want to go anywhere else once you have been there.

    Summary: Two…read moreunsuccessful attempts to make one crown. Traumatization and damage to the underlying tooth structure. Two visits to another prosthodontist to prove to Dr. Postesta-Knoll that both crowns were defective. Partial refund. The details of my entire experience are as follows: I saw Dr. Potesta-Knoll in May of 2025 and she made a new crown for me. After I left her office I had pain and discomfort to the extent that I was unable to chew on that side and had a lot of sensitivity with respect to hot and cold. I mistakenly assumed that this would go away quickly and a few days later I left for three months out of the country Unfortunately I had to endure this pain and discomfort for over three months. When I got back in August the discomfort had finally abated, but I noticed there was a lot of space between the new crown and the adjacent tooth and that food was gathering there in a way it hadn't prior to the new crown. I made an appointment with Dr. Potesta-Knoll to express my concern about the excessive amount of space between the two teeth. At this second appointment I don't know what she did other than remove some material from the tooth. When I got home I realized that it made no sense that taking off material could close the gap between the new crown and the adjacent tooth. At this point I was disconcerted enough that I made an appointment with a very experienced and highly regarded prosthodontist at 450 Sutter Street. During my first appointment he observed that not only was the crown too far apart from the adjacent tooth, there was also a ledge on the crown that made the interface between the crown and gum irregular. He sent me an email with these observations and I took it to Dr. Potesta-Knoll. She didn't seem particularly happy when she read it, but she redid the crown. Before she did the second crown I confirmed with her his observations about the "ledge" and excessive distance between the crown and the adjacent tooth, as I wanted to make sure both problems were resolved when she did re-did the crown that day. After the numbing medication wore off it felt to me that the new crown was still too far away from the adjacent tooth. I made a second appointment with the other prosthodontist and he observed that there was no longer a ledge on the crown, but that the distance between the new crown and adjacent tooth was still too much. I then forwarded his email to me about the second crown still being too far from the adjacent tooth to Dr. Potesta-Knoll's office. I received the following response from their office, "Wow, even after the second crown he feels the contact is open. It was closed when you left our office per Dr. Potesta." Not surprisingly I found the statement absurd. I'm clearly not a dentist, but don't see any way how the crown could've magically moved after I left their office. At this point I realized that there was no way I was going to trust her to do the crown properly a third time and so I sent an email requesting a refund. They requested that I send yet another narrative from the other prosthodontist stating the ongoing problem with the distance between the crown and the adjacent tooth. I did this and received an email saying they would be issuing me a refund. The good news is that I got a refund ($2,300). The bad news is that I was originally charged $3,135 for the one visit where she did the first crown. I sent them yet another email politely inquiring why I only received $2,300 and they said the $835 ($3,135-$2,300) was for an exam, a "core buildup" and x-rays. I sent them another email saying I would be happy to pay for the x-rays, but felt that it was unfair to be charged for an exam and "core buildup" when in fact I received absolutely no benefit whatsoever from my entire interaction with Dr. Potesta-Knoll. Not only did I not have any benefit from anything with the exception of the x-rays, but had to endure three months of discomfort following her doing the first crown because she traumatized the underlying tooth structure. Additionally I had the added cost and inconvenience of seeing the other prosthodontist three times to deal with this dental nightmare. Receiving a partial refund is a little like taking your car to have it repaired and not only it not being repaired properly, but the shop also damaging it. In order to get a refund they require two more emails from another shop detailing what was wrong (as well as my having to pay the other shop). When they do get the second email they deduct money for their "evaluation" and for work that provided absolutely no benefit.

The staff made me feel comfortable and well taken care of throughout my entire appointment. My hygienist, Mina, was incredibly patient, gentle, and caring. She took the time to explain how to floss and brush my teeth properly, why buildup tends to form in certain areas of my mouth, and what I can do to prevent it. I really appreciated how thoroughly she explained everything without making me feel rushed or judged. You can tell that she genuinely cares about her patients and wants them to understand how to improve their oral health. Dr. Eriksen was also wonderful. She completed my exam, carefully reviewed my X-rays with me, and explained everything in a clear and easy-to-understand way. She was very professional, knowledgeable, and attentive to my concerns. The entire experience exceeded my expectations. The office has such a positive and comfortable atmosphere, and every staff member I interacted with was kind, capable, and helpful.

My son's had regular dental care and luckily, great teeth- no cavities or braces- so he had a clean bill of health after a cleaning and exam at Marina Grins Dental. Taking a closer look at some of the reviews though, I'm nervous about a practice so eager to drill if they feel a stain could be the start of a cavity. Erm.. that feels a wee bit gung-ho. On the other hand, my son did have a positive experience, they were very polite and professional - and as one Yelper pointed out, great music! Practice is centrally located in the Marina. It's on the second floor but it has no elevator if you need disabled access, FYI.
