Diana Deidan, DDS

Oh Dr. Deidan, how do I love thee? Let me count the ways…
Is it weird to feel this passionate about a dentist? Well you’ve never met this one. Dr. Deidan and her staff are the best in the city that I have tried (and I’ve had 5 dentists before I magically found Dr Deidan).
I have horrible teeth that have been ruined by almost a lifetime of not flossing and TMJ. Dr. Deidan and her office have been nothing compassionate, kind, and incredibly sympathetic at my dental problems (while other dentists look at you like just told them you killed a baby when you say you’re not *really* into flossing).
Her office is incredibly competent, and most importantly, she knows what she is good at and outsources the rest (Pro tip: this is the hallmark of an excellent primary dentist. If your primary dentist tells you they’ll do your root canal then run for the hills!!). While other dentists have gotten greedy and try to do it all, Dr. Deidan calls in the big guns when needed even though she probably gives up some margin herself (a WONDERFUL, AMAZING, LIFESAVING and gorgeous (!) Endodontist by the name of Dr. Kim, and an awesome oral surgeon whose name sadly escapes me). There’s also the added bonus that you can select and watch your own movie while she and her staff work their magic!
I cannot recommend Dr Deidan and her staff highly enough! I’m a total groupie. I don’t care where life takes me geographically, I WILL fly back to New York just to see Dr Deidan.

Very professional staff, state of the art equipment and watch DVDs through video glasses while they work on your teeth. Doesn’t get any better then this.

I went to Dr. Deidan after my fiancé recommended her highly, and I have been absolutely impressed by the expertise, warmth and treatment. I have already recommended her to other friends of mine and wanted to share my excitement about having found a truly great dentist. She explains the procedure and takes away a lot of stress and anxiety — her colleague. Dr. Kim, is wonderful as well. Plus — love the movie goggles.

Dr. Deidan is fantastic. I have used her as a dentist for years and she is always thorough and respectful. I am very sensitive to novocain and don’t like to use it. She understands that and when I had two small cavities to fill, she managed to do them without pain and without novocain! Her staff is friendly and works to make sure you get onto her schedule when you need her – not weeks out, but right on time.
it’s nice to have found a good dentist.

I have been going here for the last 5 years and the dental service is very good.

I absolutely adore Dr. Deidan!
I found her while I was on my quest to find a good orthodontist for my invisalign procedure, and she turned out to be one of a few doctors whom I visited.
I was completely sold on Dr. Deidan from day one because she did a better job of explaining the procedure, pros and cons, and she answered all of my annoying questions in a very thorough and thoughtful manner. Not to mention the fact that she along with her staff are very, very warm and easy to talk to. She explains what she’s doing and why she’s doing it before she pokes around in my mouth– that’s a good thing.
In my case, I used her for my invisalign procedure and the whole process so far has been a breeze (especially when it came down to dealing with paper work and insurance). I most definitely recommend Dr. Deidan for those looking for an invisalign provider, or for any other cosmetic dental needs!

Dr. Deidan is a great dentist and I regret that I am no longer a patient of hers. She and her staff are personable and didn’t jab my mouth more than necessary for the work needed, and it was relaxing – something rarely heard of in the dental world.
Unlike a lot of dental offices, this one is efficient, and I never had to wait more than 5 minutes to be seen. Even transferring my documents to my new dentists was quick.

I saw her in Westchester but only for cleanings when she worked for another dentist. I liked her manner and she seemed honest. But, like I said, it was only cleanings. I would imagine that her fees in Manhattan can do some serious wallet damage.
Now…if some of you reviewers only rate a dentist by their DVD collection, you ain’t looking for a dentist, you want Netflix.

I fear and loathe all types of doctors, with dentists being at the top of my list. As a result, I do not visit as often as is generally recommended. Let’s just say it’s been a while.
Enter bad root canal.
So I had to go the dentist and I didn’t want to go to the ‘other guy’ who done the first round of work. I did a little search and Unilocal signs pointed to Dr. D. She and her staff are awesome. The vibe puts you at ease and you can watch movies to boot! I watched an episode of Seinfeld during my cleaning. How fun!
I can’t say enough good things about my experiences here. Let’s just say I’m becoming a regular…

I love, love, LOVE me some Dr. Deidan.
Painful scenario for you:
At work, about 3pm… temporary crown falls off (root canal already done on said tooth… by a different dentist… who I might add is quite expensive)…I attempt to reattach the temp. BIG mistake– pain was so excruciating, all I saw was stars. I scramble to call my current dentist… guess what? They can’t fit me in. In a fit of despair I call ALL my friends to see if they can recommend me someone (although this can tend to be a risky situation, as dentists tend not to want to take over another dentist’s work).
Fast-​forward– Dr. Deidan accepts me to come in within ½ hour of when I called.
X-​rays are taken, meds are given, appointment with the root canal specialist is set for the next day.
Result of it all: they figured out the problem, fixed it & at ½ the price what the other dentist was charging me.
AND they’re really nice & accommodating. I soooo recommend this place for your dental needs.
Remember: healthy chompers is next to Godliness… I’m just sayin’.

This office is great! I hadn’t been to the dentist in almost 5 years (eek) but if I’d known that it would be like this, I’d have gone much sooner.
The office space is neat, you don’t feel cramped or rushed in any way. Plus, the people working reception actually understand everything about insurance plans, and they explained everything to me and suggested that I make my follow up fillings appointment after I enrolled in my 2008 coverage.
Once you’re in the chair, you can watch a movie (!) while they do your cleaning! I watched 2 episodes of Sex & the City, and the dr was just wonderful — v communicative and understanding. Even when she told me I have 2 cavities. :(
