As the manager of an orthodontic practice in Lower Manhattan, I have had the opportunity to collaborate with numerous dental specialists over the years, and Dr. Lawrence Tam stands out as an exceptional clinician. He is my preferred endodontist, and I confidently refer patients requiring endodontic care to FiDi Endodontics.
Dr. Tam consistently delivers outstanding patient care. He takes the time to thoroughly explain treatment options, ensuring patients feel informed and comfortable throughout their experience. His clinical expertise, professionalism, and attention to detail are truly exemplary.
I highly recommend Dr. Tam and his team at FiDi Endodontics to anyone seeking high-quality endodontic treatment.
Dr. Angela Wu is the Michael Jordan of endodontics. I, like most people, dread going to the dentist and when I was told I needed a root canal I was spiraling. I can honestly say Dr. Wu executed the procedure with such ease that if you told me I was just going in for a cleaning, I would’ve believed you. I’ll also note I had a pretty complex canal system which she navigated better than Sacagawea. She works with such precision and efficiency you would think a machine was doing the procedure. I would recommend Dr. Wu to family, friends, and strangers alike - she is truly a master of her practice.
Would like to say Dr Sam Tsai and the whole team at fidi Endo got me in as an emergency and was able to help give treatment the same day later. They numbed me well, the report was thorough and I couldn’t have asked for a better endodontist. Highly recommend :)
Having traversed the treacherous terrain of root canals not once, not twice, but thrice under the expert care of Dr. Wu at Fidi Endodontics, I can confidently say she, and this office, is amazing. Yepp - three root canals in three weeks!
Dr. Wu's gentle demeanor and soothing words worked wonders in calming my nerves, turning what should have been a wracking experience into a surprisingly serene and simple procedure. Her professionalism made the entire process not only painless but dare I say, slightly enjoyable? The whole staff from start to finish is extremely patient and helpful. I had a lovely time interacting with all the dental assistants as well.
I've definitely emerged not only with three successfully treated teeth but also with a newfound appreciation for the artistry of endodontics.
It was amazing. I came in with a root canal that was attempted at a dentist office and it was a pretty traumatic experience. I searched for a specialist for a while before coming here. Initially it was going to be a consultation and I ended up coming back for the procedure after lunch time. Everything went really well considering how terrified I was of getting it done. I felt NO PAIN. Post root canal ( now- 5 days later) the healing has no pain. I haven’t had to take anything for this the entire time. Doctor and nurses here are really sweet! I would HIGHLY recommend. They took insurance and I had no outrageous fees like my first attempt. Really happy to have had such a high quality experience, this really changes the narrative for dental trauma!! I’ve also got direct recommendations for a dentist. Thank you and I will always come to you guys for my serious procedures ❤️ - much love
Dr. Tam was thorough and communicated well, but my case was not simple.
Update: I appreciate his phone call explain everything he could do. Thank you.
(He mentioned that he followed his own treatment algorithm which applies to every patient, and from my perspective it felt like he preferred to focus on certain type of cases.)
After checking X-rays, CBCT scan, and probing test, he recommended extraction due to a possible fracture. He also mentioned being concerned about my time and money, which surprised me. Also, he said that he is not sure he can do a better job than the 1st RC. (which is done by the general dentist)
(I later learned that even if a root canal appears fine on X-rays or CBCT scans, these images cannot always confirm whether the tooth is biologically infected.)
My gum pocket was deep (15mm), and I had a bone loss which is shaped like "J". No pains, no sensitivities. Only a pimple on the gum, pus came out occasionally.
He told me that he didn’t feel comfortable attempting retreatment because of the J-shaped bone loss (as I understood it)
(From my later research, I learned that J shaped bone loss didn’t always mean fracture, it can be a draining sinus tract or something else. I also learned that the bone can slowly regrow if the retreatment is successful. Through my research, I found that a root fracture cannot be 100% confirmed without extraction; most diagnoses are based on possibilities rather than certainty. Why do I have to know about all these, I wish this had been explained to me more clearly. I hope other patients find this information helpful.)
I would have appreciated a clearer discussion of all options up front 1) retreatment 2) attempt to retreatment and extract only if a fracture is confirmed. 3) Proceed directly to extraction.
I trusted his professional judgment. I thought he was one of the best Endos in NY from all the great reviews.
I proceeded with tooth extraction. Unfortunately, there was no visible fracture was found from outside, and I was devastated and regretted not seeking another opinion first. I regret giving up my tooth without trying retreatment even if the chances of success were low.
**My advice: get multiple opinions when facing permanent tooth removal. Your tooth is priceless. Specialists can be uncertain about whether your tooth can be saved. I hope my review can help some people who have a similar case like me.
FYI, I asked the receptionist if I could bring recent X-rays, but was told I couldn't, since their policy requires patients should take X-rays in-office.
The office could also improve wait times (I waited ~45 minutes past my appointment) and phone/email responsiveness.
Dr. Tam was fantastic simply fantastic. He listens, puts you at ease and explains thoroughly what will be happening. I highly recommend this dentist to anyone who needs a root canal. Also, his staff was well informed and fantastic as well.
