They are very professional and nice. The dentist explained every single step, she is very pleasant .

I was in a lot of pain for two weeks and needed a root canal. It took three days to get an appointment but that was for the consultation only. I worried about how much longer it would take to get the root canal appointment. Luckily, the doctor stayed late for me and did the procedure that afternoon. I really appreciated that. The doctor is experienced, fast and efficient. However, I was not prepared for the mouth insert that doesn't allow exhaling out of your mouth. I wish they had told me that ahead of time. When they had to stop to explain that I had to exhale out of my nose, I felt like I was an obstacle to the process. It was not reassuring. I didn't feel the empathy during this difficult process. During the procedure, they did not communicate where we were in the process, and if everything was going well. When the doctor was done, he did mention that there was one challenge that he overcame with intersecting nerves. Alas, I was glad to have some communication. After the procedure, the assistant gave me a t-shirt, a post procedure sheet, and told me we were done. She didn't give any verbal instructions, except to contact my dentist for my crown. She didn't ask how I felt and/or if I needed to take a rest in the waiting room. In fact, my back hurt for two days from the angle which I was reclined for a prolonged time. Otherwise, my recovery has been good and I'm thankful for that. As for the expense, it's not cheap to get the advanced xrays and the laser treatment. Even with insurance, those x-rays are not covered. However, it's the highest standard of care, which helps the doctor give patients the best treatment. read more

Terrible experience! Prior to the appointment I was told that the root canal would be done. That was very clear, arrived to the appointment only to get x-rays and a rude dentist Dr. Ryan Brennan who stated he didn't have time for me. Claimed he had a family to get home to and also had an appt. after me. Was given the option to "RUSH THROUGH IT" who in their right mind wants to rush through a root canal because their dentist has other priorities and an appt in 20 mins. Truly horrible service. read more

I am a Veteran who was referred out by the VA hospital after seeing them for an emergency walk in visit for excruciating tooth pain. Turns out I was in need of a root canal on 2 molars. The pain was so great that the VA did an excellent job of expediting authorization for an Endodontist to complete the root canal procedures. Because of my past traumatic dental experiences in the military I get quite anxious when having to get dental procedures done, I will typically even request nitrous oxide (laughing gas). so I was careful to do my research and choose a proper dentist office with decent review. I decided to go with Advanced Endodontics in Lake Mary, the earliest appointment they could give me was a week out so I had to tolerate the pain until then with the help of antibiotics and over the counter medication. Needless to say I was counting down the days to the appointment so I can get relief from this painful feeling. I even had to take the day off from work in order to arrive to the appointment. Braced for the procedure ahead I made it to the office on time for my scheduled appointment, the lobby was empty and I'm checked in by the receptionist fairly quickly, the dentist's assistant takes a few x-rays then sits me in the dental chair and advises the Dr that we are ready. The time was 3:15pm The Dr. rushes in and hastily reviews the images that reflect the tooth needing a root canal, Asks me which tooth hurts and the pain level, taps on it, does a cold test on it (as if it isn't painful already) concurs that it DOES need a root canal then tells me he "Might" be able to do 1 if we hurry it up. At this point his rushed demeanor made it feel like this was going to be a less than pleasant experience and was not very reassuring. I asked him if he had the time or even wanted to do this to which he replied "well I do have someone after you and I have a pregnant wife that I have to get home to" "If you'd want to reschedule we can do that". I tolerated agonizing tooth pain for a week and took time off of work in hopes of getting a good Dr and pleasant experience only to encounter a dentist who had no intention of honoring a scheduled appointment and patient in need of dental care. I called the VA to advise them of the experience and situation and am now having to go through the process of finding another office. read more

If I could leave zero stars I would. I had a root canal here two years ago. I continually had sinus infections and on antibiotics time after time. I was finally sent to an ENT back in April, 2023. He did a CAT scan, and said that this chronic and recurring infection that would not go away, was due to a root canal I had in the past. I have only had one, and I didn't realize how horrible the experience was until I had to have this redone. I saw another endodontist, he said it was a very poor job by whom ever did this before. I had to pay almost $500 after my dental insurance was exhausted to have this fixed when it was repaired, he said it was definitely a job that was not done correctly. And there was a lot of infection in there, I know for a fact there was common as disgusting as this is, I could smell it when he was working on me it was so bad it made me feel sick. I realized how traumatize I was from the actual first experience at Advanced Endodontics, when the correction was done this week. Even though I had gas at advanced endodontics experience, we still traumatic. The doctor had poor bedside manner, not to mention I was leaving getting in the car, when they called me back in because they needed to fix something! I went back in, they opened it up again to fix whatever clearly he truly did not fix properly! I should've realized right then and there there was going to be a problem. DO YOURSELF A FAVOR AND STAY FAR FAR AWAY FROM THIS GROUP!! read more

The staff were wonderful, helpful, attentive, kind and thoughtful. I was informed at every opportunity of what steps were going to happen and what was happening. 10/10 would recommend and would go back, if I needed another procedure completed. read more

I was referred an endontist because my dentist moved on and the replacement does not do root canals. So I walked in the door at advance endodontics, knowing exactly what I needed with a referral in hand from a dental office. My first red flag was when I called to schedule the appointment. They said they had to do a consultation first which I get might make sense But when I came to learn is they charge the $60 partial Oral evaluation. Basically I open my mouth and she's like yup you need a root canal. In addition they did a pulp vitality test even after I told her I'm having no pain I have no sensitivity. I just need to get it done so this test was $69, and then add additional fees Walking out the door I paid them $105 for them to tell me that I needed a root canal something I already knew. My appointment was at 9:45 AM. They did not take me back until after 10am even when I arrived early, I had already already pre-registered and taken care of all of the paperwork. Then to top it all off they're forcing me to agree to a scan of the tooth that they say they need in order to do the root canal, I've had three other root canals that I've never had to have this done. They were being very aggressive and pushy about it and we're not respecting my feelings. I would not recommend anybody going to this office. It was brought to my attention that a lot of people leave there feeling the same way. Intentionally do things just to get money out of people that they don't need to be doing. That's a fact.! The person at the front desk you have to repeat yourself multiple times to which was annoying. And then they told me that they could not use my dentist x-rays that were just taken within the last five months because they can't be opened and I have them on my phone. I can see it just fine. Beware of Lake Mary location . They will definitely try to charge you for things that you don't need so make sure if you go there to push back on them.It read more

My Dentist is very close to AE in Lk. Mary. I needed a Root Canal so my Dentist suggested I go to AE. I literally walked from my Dentist to AE, filled out the paperwork, and then got slammed with a price of $1,823.00. I let them know I had insurance and they said it didn't matter, I'd have to pay the full price that day. Of course I wasn't happy and left for my office to call Dr. Temple in Orlando, I've used him before and he's great. When I called, they were pleasant and still had my insurance on file. My out of pocket is $186.00 and $375.00 for the CBCT x-ray. The lady at the front desk at AE was rude, and they sure are proud of their service. I would not recommend AE! read more

This place was great, will never go anywhere else again! The dentist was great and they dentist helpers were even better. I felt no pain for my root canal operation.. read more

Dr. Brennan and his staff at AE were amazing. His team knew I was anxious about getting a root canal and helped me through it with no problem. I would MOST DEFINITELY RECOMMEND them to anyone who may have a phobia about dental work. read more

Okay, I had a great experience at this place. I was a new patient and explained my situation. They actually got me in the very next day when I mentioned how much pain I was in. They performed a double root canal and two days later I am pain free after having suffered for almost a week. Everything was explained perfectly and I was out of there in about 2 hours! Everyone there was super nice. Not that I want to go through it again, but if I do I know exactly where I am going. PS: I filled out there online form and I think it helped things go a lot smoother as they had no issue with my insurance and they charged me exactly what was quoted. read more

I went to the Lake Mary location, for my consultation which was $142 plus $82 in fees I paid that then I sat in the chair doctor came in for 30 seconds and said I needed a 3-D scan. I did that that was an additional $263 plus $82 in fees. He came back in and said they could not do anything. I should go back to my dentist and have them repair $500 out the door within a half hour I felt scammed. read more

I took my 14-year-old son to have a root canal, and he was completely scared because he had been in so much pain. The staff was amazing the minute we walked in. The lady that greeted us at the front desk also took my son back and prepped him to see the physician. She was also communicating with another assistant to make sure that everything was prepped correctly. The teamwork and the clear communication they had with each other was amazing. I had a feeling they were short-staffed, not because they looked stressed, but because there were not a lot of patients in the office. When the doctor came in, he was just as nice, and he explained everything in terms I could understand. The 3 of them worked together so smoothly. One of the ladies even walked out to get lunch for her and her coworker. The only way I knew this was because the doctor asked the assistant if she had eaten lunch yet and wanted to make sure his team had something to eat. After all, they were the only two there that day. Even though they were short-staffed, they made my son feel comfortable and relaxed. They laughed with him and gave him a T-shirt that said, "I survived a root canal" This office, hands down, was terrific. With everything and everyone stretched thin because of Covid, this office didn't even show any deficiencies in their workflow. read more

I was searching for an endo to help assist me with a rootcanal for my 8 yr old Granddaughter. She was in so much pain and scared that she would need some nitrous oxide to help her. The staff was amazing. They got us in same day even though they were busy. They all worked together to help keep myself and my Granddaughter informed of what they were doing. Dr. Brennan was so awesome and explained in detail about what we were dealing with and what our options were. I had been to 6 other endo's and none of them went into the amount of detail that Dr. Brennan did. I was very pleased with everything that the entire staff did to make our visit a happy one. Keep it up team. read more

Dr Brennan and his Assistant Ellie are the best! I went to the Lake Mary, FL office and my experience was awesome. I highly recommend Dr Brennan! I was in pain and needed a root canal and Dr Brennan was knowledgeable and did my root canal the same day! read more

The Lake Mary location were able to see me as an emergency patient, they were very professional and they have gas and air which is awesome for pain relief!!! ***Update*** my root canal resulted in a serious infection. When I called the office due to pain and swelling the day after the root canal I was told to take Motrin as it was an anti-inflammatory but 2 days later and I'm in the ER! I stayed in the hospital overnight due to the severe infection and awful swelling that obstructed my throat! To be fair the office called to check on me but I had to drive to their office on discharge from hospital only to be told your tooth should be pulled but we can't do it... No apologies and no discount offered for the poor information. Had they said it's 50-50 on saving the tooth I would not have bothered with the root canal on the first place. The Dr. Was overconfident and pretty disrespectful in providing a service he couldn't guarantee! But the advice from the office to take Motrin was incomprehensibly stupid! read more

My experience with Dr. Chen & staff was great. A very nice and comfortable atmosphere, pleasant & professional staff and timely service. I especially enjoyed being able to listen to Pandora via headphones during my procedure, allowing me to be relaxed during a root canal. My only dislike, if you want to call it such, was that they asked for payment during a pause in the 'pre-op' phase. Asking for payment while you're sitting in the chair, getting your mouth numbed up, just seems a little on the 'tacky' side to me. Seeking the services of an endodontist, I obviously have the ability to pay so ask for it either before or after the treatment. Otherwise, I would definitely recommend Dr. Chen. read more

My experience at Dr. Chen's office was really amazing. I had a last minute emergency and had to see an Endodontist right away. Dr. Chen was able to accommodate his schedule and fit me in around 1:45pm. He did a great job at explaining the problem and all the different options I had. He really took his time to make sure I understood the situation. This was my first time having a root canal and it was a breeze. Dr. Chen was quick and did an amazing job. A special thank you to Dr. Chen's staff: Paige, Sue and Breanna! They made feel calm and were very helpful during the entire procedure. This made everything go so much smoother for me. I would highly recommend Dr. Chen and his practice. read more

I felt like I was in a car showroom where they were trying to step me up. When I called for an appt., I asked if they honored a dental card I paid for. They said yes but when I was presented with the bill, it was higher than it should have been. They said they discount from their prices but don't actually give the actual discount from the card. When they took an X-ray, the tech had to ask another person how the fix the piece that holds the film. That's not instilling confidence. And then she told me that I needed a $250 scan so they could see the tooth better. And to top things off, they charged me $142 for an x-ray and a consultation that lasted about 12 minutes. Not a pleasant experience. read more

I went to the Lake Mary office to get a root canal done. Can honestly say it was one of the best experiences I have had at a dentists office. The facility is first rate, the staff were just so friendly and very professional. I sat in that chair for just a little over an hour and not once did I ever feel any pain or discomfort. (Unless you consider the sound of a dentist drill a discomfort) I would not hesitate in going back there again if the need arose. If you are here looking for a positive review and a recommendation, then you have it from me. Go there. You will not be disappointed. Good luck with your procedure! read more

Outstanding customer service Very professional staff Painless dental work wait time was minimal and I received a follow up call hours later after the procedure. read more

They were able to fit me in right away and ease my anxiety about the whole situation. Chelsea, Chaniff, and Dr V were a dream team. I would recommend their office to anyone and everyone that is in need of a root canal. Thank you for making this experience above and beyond my expectations! read more

I'm grateful he was able to see me right away. He was highly recommended by family dentist. His office was clean and mostly everyone was so professional. Thank you Dr. Chen!!! I'm bringing you home made Kim Chee... read more

Dr Brennan was able to see me that day and take care of me. Every one was professional and friendly!! Dr. Brennan explained what he was going to do and how we would handle any problems that might happen. Would recommend to anyone that hates getting a root canal. read more

UPDATED: No parent ever wants to hear that their child needs another root canal. But when our Dentist tried to recommend some else, my daughter said "No, I want to go back and see Dr V from Advanced Endodontics." Once again, everyone was so helpful and friendly. Chelsea got us checked right in and updated our file from last year. Chaniff then got my daughter all settled in for the procedure and made her fell completely comfortable. My daughter was excited again to watch a movie on their iPod with some over sized headphones to hear better. Then Dr. Vaidya came in and answered all our questions and got right to work. 40 minutes later, we were out of the office and on our way home. One of the best experiences for a bad problem. I highly recommend them!! read more

They truly do everything possible to make sure their patients are comfortable. Most enjoyable experience I've ever had at a dental office.

I have now been to this office for 2 root canal procedures. Dr. Chen is very professional and considerate of his patients' feelings. I really appreciated that he took time to go over a treatment plan and wanted to know my opinion as to which options made the most sense to me. Also, the office is lovely. Very clean and pleasing to the eye with state of the art equipment. read more

When you find out you need an emergency root canal, you are obviously less than thrilled. However, Dr. Chen and his staff made one of the more unpleasant things in life as pleasant as they possibly could. The office is immaculate and I was immediately greeted by the nicest lady, who offered my complimentary drinks and a snack. I didn't have to wait too long, and that's amazing considering they fit me in as an emergency root canal that day. When I went to The office, I got to pick my tv or movie show in the big screen. The assistant that kept coming in was really nice, as well. Easy going and funny. As it was getting closer, I got my own personal iPod to watch Hulu movies on and use wireless headphones, which are a necessity with dental work. Less anxiety when your mind is watching movies and not hearing the sounds. Dr. Chen was super easy going, seemed laid back, and pretty funny from what I could tell. It was painless (uncomfortable just because of the whole mouth open for an hour thing). They couldn't finish that day, so I had to return a few weeks later to complete the procedure. Again Paige and Dr. Chen were super awesome, put me at ease, and done in about 40 minutes. No one wants a root canal, but if you're gonna need one...this is the place to go. Thanks everyone at AD!!! read more

I cannot say enough great things about the staff and Dr. Brennan! They are always prompt, friendly and amazing at what they do! I had 2 root canals done at the same time about a month ago, Dr. Brennan was very knowledgeable, gentle, friendly and I had absolutely no pain or complications. read more

What a great team! Allison was so kind and caring when after hearing I contacted 4 other endodontics and no one could help me for weeks. She called me with a opening in Lake Mary for the next day. Beth greeted me with a smile first thing in the morning. Dr. Brennan and Leslie were Awesome! They took away my pain and Leslie even sang along with the office music as if they were lullabies. Fabulous facility! They were worth the 45 minute drive. Maybe you will open another location in SW Orlando? Would recommend to everyone!!! read more

The most pleasant dental-related experience I've ever had -- and I've had many. Beautiful office and lovely team. Beth, Chelsea, Leslie and Dr. Brennan were so kind and concerned for my well-being. I appreciate how careful and observant they were, especially because I was 8.5 months pregnant. My safety and the safety of my baby were treated as top priority. read more

I did not hesitate to come back to this office for my 2nd root canal. This time with DR Brennan. The treatment was painless and fast. The Lake Mary office is beautiful, comfortable and easy to get to. Their Website is a great source for information too. Most importantly, the staff is top-shelf! I highly recommend DR Brennan + DR Chen and I hope you have the pleasure of getting Elana P when you visit - she's a hoot and put me right at ease. I even got a shirt too! I cannot say enough about this place! read more

I needed an emergency root canal the same day I met with my dentist. This office saved me and squeezed me in without 30 minutes of my dentist calling their office. Beth at the front desk was so sweet and helpful. She even set up a movie for me to watch during the procedure. Saamiya assisted Dr. Brennan during the procedure. They were both very professional and I knew I was in good hands. I highly recommend going to this office if you are in need of a root canal. Thank you for the sweet gift bag too! read more

I had a root canal therapy done on a molar with an old silver cap. They were very friendly and professional. I couldn't chew on that side because of the problem and they saved the tooth! They gave me a little care package along with my post-op instructions. They even called me the next day to make sure I was doing all right! I would highly recommend them! read more

This was an amazing experience...as far as root canals go! My dentist, Dr Watson, here in New Smyrna Beach insisted I go to Dr Chens Ofc. I live an hr away so I insisted they refer me to someone closer but he wouldn't! Dr Watson said he would only let his wife go to Dr Chens Ofc so I went. The Ofc was modern, beautiful, & very clean. The personal were all very helpful & friendly. Judy, my dental assistant, was so friendly, trained in the Army & offered me music or a movie, I chose a movie. Believe it or not...I watched "Blended" & LAUGHED all the way through the root canal!!!!!!! read more

Today was second time at Advanced Endodontics and the first time with Dr. Chen and I must say he is a master at what he does. I have always been treated the best ever and today was no exception Chaniff assisted Dr. Chen and she was extremely professional. They are a top notch office from the moment you walk in the door and there new location is superb, just beautiful. Thank you for the awesome care! read more
