I cannot say enough good things about Kelliny Endodontics. From the moment I walked in, I felt cared for and completely at ease. Let's be honest -- no one wants a root canal -- but Dr. Kelliny made the entire experience smooth, calm, and surprisingly comfortable. He is incredibly professional, gentle, and thorough. He explained everything clearly, answered all my questions, and never made me feel rushed. Even after my root canal, I felt supported and well cared for. My recovery has been smooth, and I truly appreciate the attention to detail and follow-through. If you are anxious or nervous, this is the place you want to be. Skilled hands, a calm spirit, and true professionalism. I'm so grateful I was in his care. Highly, highly recommend. read more

Dr. Kelliny is legitimately one of the top Endodontists in the field. I worked for many years making tech for the dental industry, and Dr. Kelliny was highly recommended by my previous colleagues. My appointment was very quick and smooth, and in addition to being very knowledgeable, Dr. Kelliny and his team were all very friendly. read more

I want to start by saying the root canal that Dr. Kelliny did on my tooth turned out well. The reason for my 1 star is completely his lack of unprofessionalism while discussing charges and also having Diana in the front office falsely claim I made a root canal appt instead of a follow appt for an ice test. In 2023 I came in for an appointment for a consultation. At that point, I wasn't ready for a root canal and needed a crown. The consultation was covered. My tooth calmed down but in 2025 I went to my regular dentist to get a crown and he suggested since I was still having pain that I go see Dr. Kelliny again just to make to make absolutely sure I didn't need a root canal. There was some question about it being tooth 2 or 3 that was the issue. I was told before coming to the appointment that the consultation should be covered since it had been a while since my last appointment. I came in and it looked like tooth 3 had the worst reaction to the ice test and needed to be dealt with first. I was told that pain can move forward and it's kind of really hard to tell which tooth is the problem or if they both have a problem. Since tooth 3 acted more negatively during the ice test we decided to go ahead and do the root canal for tooth 3 first and we could review tooth 2 once this root canal was healed. A couple days after the procedure I had an intense reaction to cold on tooth 2. I set up an appointment for the following week with someone in the front office. The tooth ended up settling down. So I cancelled the appt. Two months later, I started having sensitivity issues again. At that point, I decided to book the follow up appointment for tooth 2. I called and spoke with Diana and let her know what's going on with my tooth and the entire situation. Again she told me that the appointment should be covered and if not, it wouldn't be full price. Upon arriving at the office for my final appointment to essentially just do a follow up appt on tooth 2, I was told that I had booked an appt for a root canal. I think as a 51 year-old adult I would know damn well if I booked an appointment for a root canal or not. I never booked an appointment for a root canal. All I needed was to recheck the tooth 2 now that tooth 3 had been dealt with. I was dumbfounded. I expressed this to the nurse in the room and said I have no idea what's going on here. I never booked an appointment for a root canal. She then said to me well they had a cancellation and thought they would fit you in if you needed it. I let if go at that point and let them do the test. Two months later I was just surprised to receive a bill of almost $400 for things that were not covered by my insurance. They had plenty of time to do a proper check and consult my insurance before my arrival to make sure they were billing me correctly but neglected to do so. I spoke to Diana and was told to talk to my insurance company. I called them and the first woman I spoke with said it seemed like a code error issue. She also told me that Diana could have gotten all this information if she reached out very quickly and that most dental office do reach out and have proper estimates prepared. Diana just put the ball back in my court and the entire blame on me. I let her know that I am not the dental professional and she did not have my back in situation. She refused to take responsibility for any other things that have gone wrong. I spoke to Delta Dental and filed a grievance where we called the dental office back same day. Diana took down the information and gave us dates and said that Dr. Kelliny would call me back. I got a call back from Dr. Kelliny about two hours later. He was already on the defense and speaking in a very accusatory manner. Instead of listening to the complaint that I had, he talked over me and only wanted to tell his side of the story. I never fully got to express what happened to me and before I could even finish telling him how I felt about the third visit, he was telling me that I wasn't welcome back at his office and that I absolutely booked that appointment for a root canal that I never booked. At that point, I didn't trust his judgment as a medical professional any longer and hung up. There is no use in trying to express what I felt happened to me as a patient in his office when he already pre-determined that I was wrong and would only side with his front office person Diana. I told him I really wished they recorded phone calls at his office though before hanging up. These people do not like to be wrong so don't bother trying to remedy an issue with them. You will not win. Apparently questioning this doctor is a no no. Now that I've had time to think this over, I wish I would've recorded all my calls to their office. That's my advice to any new patients. Record your calls or don't bother coming here. read more

Dr. Kelliny and team are truly amazing and top notch across the board. I had an infection that other dentists missed.

What a great experience I had today. The staff was so friendly and knowledgeable too! Highly recommend them.!!!

Dr K and staff were outstanding. Dr K is quiet spoken, big smile, listens to your needs, and always asking if you are OK and comfortable during the procedure.

Clean, Professional, on time and respectful of my time as well. Highly recommend his services and anyone he would recommend as a result. read more

Dr Kelliny and his staff are simply the best in every aspect of endodontics. I had a bad experience with a previous root canal which had to be redone and Dr Kelliny eased my anxiety and flawlessly performed another root canal with no pain at any time during the process. I only wish that he also was a general dentist!!!! read more

Dr Kelliny was amazing! I had to get 2 Root canals and was very nervous before the procedure. Dr Kelliny and the staff patiently answered all of my questions, made me feel at ease, and were attentive throughout the entire process. They somehow made a root canal a pleasant experience (as far as root canals can go). Highly recommend Dr Kelliny and his superb team. read more

Dr. Kelliny did a great job. I came in with terrible tooth pain, but he didn't rush into any treatment, he carefully did some tests and in an abundance of caution advised me to take some preventative measures rather than getting a root canal which might not be needed. The pain has gradually subsided, so he was spot on. I'm glad I was referred to Dr. Kelliny. read more

The best endo in the South Bay for sure. Have been with him over 10 years & won't go to anyone else!

Friendly and attentive staff & doctors. My procedures were smooth and painless. Highly recommend.

Dr. Kelliny and his staff were very nice. Everything was clean, which I appreciate. I am a dental chicken for sure but Dr. Kelliny and the girls took care of me. They gave me a pillow to hang onto and when the treatment wound up being more complicated and required a second appointment, they left nothing to chance. The doctor wrote a prescription to help me relax and they arranged for Nitrous Oxide. Healed up just fine. Thanks read more

With the help of my dentist referral, a dentist on Dr. K's staff likely identified and solved a endosinus issue that had affected me for several years that I had mistaken for allergies. While root canals are not fun with dental dams and dripping down your thought - the staff was very supportive and the procedure and recovery have been relatively painless. Root canals are not the least expensive procedure either - but thanks to Pacific Smiles and Dr. Kelliny's office - very happy in resolving this issue. read more

From the minute you walk in every single person that works here is EXCELLENT. I will be back I need some work done and totally trust Dr. Kelliney and staff. read more

Reply, Yes, I do understand that. But the fact that, I was told, that's all the payment I need to pay. I made sure with your billing department. They even told me, I was not going to receive any bills later. The insurance was ran, not covered portion was paid. What part I don't understand is, the things not covered is being charged after months? That's a loop hole in the billing. I took my appointment weeks after billing and insurance was ran, I have never had this issue with any other dental practice I have been too. read more

I took my 19-year-old son here for a root canal utilizing his gentle wave approach. My son was coming from dental trauma and this was his first time back in the dental chair after a 3-year hiatus. He was incredibly nervous and afraid. The staff and Dr. Kelliny were kind and patient. They explained everything and set my son up with a helpful mix of laughing gas and sedatives. He was able to relax and allowed the dentist to do his amazing job. Dr. Kelliny was gentle, precise, and excellent at what he does. There was no pain and my son now has a new start with a good dentist, which will keep him going back to them. Thank you Dr. Kelliny and the AMAZING STAFF! read more

I had a horrible toothache all week and knew that I needed a root canal and have been dreading it. I was able to get an appointment with Dr. Kelliny within a day so I was very happy with the quick response. I must say that the entire procedure was so efficient and painless. Dr. Kelliny and his staff are amazing! I would highly recommend going to him if you need a root canal. The only advice I would give is be ready for the pain and soreness after the numbness wears off from the local anesthesia. Just make sure to take the antibiotics and some 2 tylenols! Overall I had a great experience with my root canal and I am so happy I went to Dr. Kelliny. read more

I have been a patient of Dr Kelliny since 2011. He is a fabulous doctor. Very professional and dedicated. The waiting room is very comfortable and offers free Wi-Fi for patients.

His staff are well trained and make you feel very comfortable. read more

The staff was great. Quick easy check-in and I was sitting in the doctor's chair in just a few minutes. My root canal was completed quicker than I expected and without any pain whatsoever.

I was referred to Dr Kelliny's office for a redo of a 6 year old root canal. I had an infection due to not all of the root being removed the first time. I would highly recommend this office for endodontic work. The office is amazing. It starts with his staff and extends to the doctor himself. Everyone is so friendly and kind. They listen to your concerns and work with you to make you as comfy as possible. I am a nervous Nelly but also curious and every step off the way they explained what was going to happen. At all times they were ready to stop if I became too uncomfortable or needed a small break. I hope I never need another root canal but if I do - this is where I will go. read more

Dr. Kelliny was recommended to me by my general dentist. I've been to Dr. Kelliny on several occasions In the past year to correct root canals that were inaccurately performed several years ago. I wish I had known of Dr. Kelliny several years ago and mainly the reason I'm writing this review. To help others find him when they need a specialist who will get the job done correctly the first time! Dr. and his staff all have wonderful professional personalities that quickly makes you feel at ease. I particularly like that Dr. Kelliny and his team are very organized and thorough. I know I can trust them because I see their due diligence. Getting work done inside your mouth is never a comfortable process but out of all the dental offices I have been to, this office is the best thus far! read more

While on vacation in California last week, I started to experience some pain in one of my upper molars. I had told my son if I had the same pain by Friday when we had to fly back to NY they would have to sedate me. It was after hours, he called some emergency number, they gave us an appt for 9:30 in the morning for Dr Michael Fulbright , he then referred me to Dr Kelliny; within a half hour I was sitting in his dentist chair getting prep to get the work done in my mouth. I was so relieved to see the compassion & professionalism, that was shown towards me by Dr Kelliny & his staff. I had major work done that day, he saved my vacation. I felt 85% better later that day & 100% by the next day. Words cannot express that while on vacation I found a dentist that knew what he was doing, & made me feel at ease. Thank You Dr. Kelliny!!
