I am so glad I found Dr. Jovanka Zivkovic. She is one of the most honest, professional and kind people I have met. Her work is amazing! She is very detailed and perfectionist which is what I need when it comes to my smile. She went over all the things I needed and explained the urgency of each thing. She explained the financial part of the process (which her amazing staff explained in more detail before any work was done). I felt comfortable from the first day I met her and am so blessed I found her. I will be her patient for life!

I found Mamut Dentistry after looking for a dentist in Astoria. My dentist was very professional, and friendly. I like the fact the she took her time to clean my teeth with efficacy–no pain, no regrets. It’s a bit hard to find a dentist with such patience. Sometimes I used to leave my other dentist’s office with pain on my gums because he was always too rough. Not with this dentist–it was a different and positive experience whit her. The front desk girl is very nice as well. She even emailed me the “first time patients’ form” to fill it up at the comfort of my time before the appointment. So I didn’t have to wait for too long to be seen by the dentist on the day of my appointment. If you are looking for a good dentist, this is the place to go. They even have good payment options for people with or without insurance. Hence, I highly recommend it.

Dr. Jovanka Živkovic is not only an extremely qualified dentist, she is also very enthusiastic about her work and lovely to be around. She radiates confidence and inspires a comfortable and secure atmosphere, which is quite appreciable when you’re being poked with needles and having teeth extracted. But everything mentioned above, would be for naught, if she was not the most expeditious doctor I have ever met! I have never been in and out of a dentist’s office so promptly in all my life. I would highly recommend Dr. Živkovic to anyone eager to enhance their dental health.

Absolutely 5+ stars!  Dr.  Zivkovic is one of those doctors that you are truly lucky to find.  In a sea of doctors that push patients through, Dr. Zivkovic took the time to put me at ease, was personable, caring, gentle and went above and beyond in her follow up checking on me.  I recently went for 2 units of Botox and some Juvederm.  Her gentle touch, less is more attitude for a more natural look and happily offered a follow up if I wanted or needed more.   No more wrinkles and my cheeks and face have a full and defined look.  I immediately received compliments and would highly recommend!!

I brought my 16 year old daughter to Mamut Dentistry for an Invisalign consultation. Dr. Jovanka was absolutely amazing! She explained every part of the process thoroughly and did not pressure us in terms of moving forward. She took the time to explain the before and aftercare to my daughter to make sure she understood what she was signing up for. I am confident we will be moving forward under Dr Jovanka’s care!

Stevan P. from Buena Park, CA (Source: Yelp)


Dr. Zivkovic is one of the best dentist I ever met. She is very professional, and the quality of her dental work is exceptional. I recommend all my friends to go see her as I know they will have the same great experience as I do. Her assistant Kristina is always helpful and knowledgeable when it comes to dealing with insurance and scheduling the appointments.

Kristina T. from Manhattan, New York, NY (Source: Yelp)


Truly amazing experience from first contact with assistant Kristina! This was my first visit to MD, I was very nervous and scared but the assistant Kristina smiled and assured me that everything would be okay. I met with Dr. Jovanka and she greeted me a smile and hug that put me more at ease. If you’re looking for a friendly dentist who will explain you every proces very thoroughly before doing it and give you NON painful and NON stressful experience, than Dr. Jovanka is perfect choice for you! Thank you for relieving me from all the pain and helped to get over my dental phobia!

My experience at Mamut Dentistry with amazing Dr. Jovanka is nothing but the best. I’ve never encountered someone so dedicated to help patients out even without insurance. I will never change my dentist and thank you for all that you do! Stay amazing as you are so far. P.S. I had big dentist fear because I experienced some awful dentists in my life but Dr. Jovanka changed that now I smile when I sit in that chair so THANK YOU! :))

I have recently found Dr. Jovanka and I am so glad I did. Her staff is amazing and so is she! She is very professional and truly honest. Dr. Jovanka will not do something you do not need ! Her work is impeccable! There are no unnecessary appointments – but she is very punctual and thorough! The 5 crowns she did look amazing and feel even better! I have already recommended her to everyone and will be her patient for life! Our whole family goes to her (from the city) and we all love her work! Truly a gem!

Mila P. from Queens, New York, NY (Source: Yelp)


Amazing dentist place! Dr. Zivkovic and her office manager are very professional, helpful and super friendly. I had my wisdom tooth extracted few weeks ago. It was quick & painless. Dr. Zivkovic was very clear in all of her steps and care that should be taken afterwards. Thank you for taking such a good care of me!

Paige R. from New York, NY (Source: Yelp)


If I could give more stars I would! Dr. Jovanka Zivkovic is nothing short of amazing in everything she does. I came in one day for a cleaning and now a month later have had a cavity filled, Invisalign in process, and juvederm filler done. I trust her with anything. My teeth are on the way to being straight and my lips look so good! Dr Zivkovic and her staff are super accommodating and very professional as well. Kristina, the office manager, is on top of everything and will make sure you are satisfied. Thank you Mamut Dentistry!!!! Highly recommend.

So happy I found Dr. Jovanka Zivkovic. She is amazing! Professional, kind and honest. She told me what I needed to get done, never forced me into anything and was open about pricing and the urgency of each thing. She explained everything to me, showed me xrays and explained what everything was. Aside from her, her staff is very professional and kind. I always feel so comfortable and I trust them! She is a gem that I am so happy we discovered and now I am recommending her to all of my friends.

Mitre B. from Astoria, NY (Source: Yelp)


Amazing service and exceptional work. Hated going to the dentist since I was a kid(like many others), but ever since being referred by a friend I’ve never had a better and healthier looking smile. Dr. Zivkovic is very talented and will definitely fulfill all your needs for an amazing smile. Highly recommend.

Slobodan R. from New York, NY (Source: Yelp)


Jovanka is by far the best dentist I had so far. Professional, kind, caring and careful. She really understands that going to a dentist is uncomfortable for some people and will make your stay there very pleasant. She was able to identify issues that I didn’t know I had and that my last dentist has missed. Also, she took the time to educate me more about my teeth and to give me practical advice that will keep them healthy. I strongly recommend her services.

Best DENTIST hands down in NYC!!! From the first visit it has been a great experience. I had 2 crowns that had infections and went for a consultation. Dr. Jovanka explained in detail about what we can do that will give the best result so the will be no more issues again. I have sensitive teeth with her expertise I am PAIN FREE!! Loves her profession and know its to a T! I highly recommend Dr.Jovanka for anything from a simple cleaning to implants. Go see the best in the business you won’t regret it!

Everything about my experience with Mamut Dentistry has been exceptional. Dr. Jovanka Zivkovic is true artist and truly passionate about hers profession. Dr. Zivkovic takes the time to explain everything that is going on and gives a good advice and guidance. I had extracted two teeth and during the procedure I felt no discomfort, healed quickly with hers easy to follow instructions. I’d rate her work/technique 10 stars! Extremely professional, attentive thorough and precise in explaining her approach and what to anticipate. She proactively followed up on my recovery. Warm recommendation for anyone who needs dentist!

The most amazing dental experience I’ve ever had. I would not look any further for another dentist as there literally is no pain. She cured my fear of the dentist when she pulled out my wisdom teeth, I didn’t feel a thing and it healed in 1 day. My mouth was not even swollen. Everyone has a guy for something, even if it’s for a car, a doctor, an accountant, broker, dealership; well Dr. Zivkovic is “my guy” for teeth. She did my mothers veneers and they look amazing. Top shop, 4 thumbs up.

I had a pain in my gum and went to Dr. Jovanka’s office. She was able to help me out and she had explained to me very thoroughly about my dental issue. She pleasantly surprised me today with how quickly she was able to extract my front tooth and do the bone grafting. There was no place for any discomfort, since she was very gentle with me. I’m proud of her, and grateful that I’ve found a dentist that can do many different dental procedures herself. She had showed me one more time not to ‘judge the book by a cover’. Although she looks young, she has a great dental experience. I’m healing and I’ll keep you updated about the final outcome with my implant in few months. Thank you, thank you! (; Zoka

Dr. Živković is an amazing dentist that takes care of business without making the experience a hassle. Not once have a felt a pinch of pain which for me is very important. She is very gentle, yet strong, and thorough with all her work. She is prompt with appointments and works to accommodate her patients. She has been working on an implant for me and I a beyond grateful for the experience. Highly recommend her to everyone!

Vanja O. from Manhattan, New York, NY (Source: Yelp)


I know amazing work when I see one. Dr. Jovanka is amazing and so is her staff! They are friendly, professional and honest – all you need in an amazing dentist. She is honest with her patients and will openly tell you what needs to be done. She will not start any work until you completely know what is covered and whats your responsibility. Above all – Her work is impeccable! I am so glad we found her! A gem!

Nenad K. from Chicago, IL (Source: Yelp)


Dr. Jovanka is one of the nicest person you’ll ever meet and above everything she’s a real expert in her field. She really makes going to the dentist stressless experience and before she starts doing anything, she makes sure she explains and guide you through the whole process. Highly recommend visiting her office! You come in as a patient and you leave as a friend!

I’ve honestly never had better experience with the dentist than with her. Dr. Jovanka Zivkovic is really professional, straightforward, very kind and patient. She is truly special and I would always recommend her to everyone. My daughter is not afraid of going to the dentist anymore. I’m so grateful for knowing her!

Coming from someone that has been around with Dentists since very young, in the USA and in some other countries, this has been by far the best experience I had. From the moment you walk in, the staff welcomes you with a smile, all around you feel the cleanness and coziness. You barely wait to get in, not like your regular Dentist, and people lets face it, who likes to wait long?! As far about Dr. Jovanka Zivkovic, she immerses you with a very straight-forward, honest and perfectionist experience, while doing a very meticulous procedure like Sinus Lifting Dr.Jovanka still manages to make you feel comfortable and have fun with her down-to-earth personality, ending in am amazing result. Definitely a must go!

Marta M. from Manhattan, New York, NY (Source: Yelp)


Dr. Jovanka has by far been one of my best experiences in dentistry and has changed my life with the Invisalign process and more. She is very caring and supportive in every procedure. Not to mention, the front desk is more than happy to help schedule any appointment at any time and is there to assist you on the first ring. Dr Jovanka is also a complete smokeshow.

I visited Mamut Dentistry yesterday for my Phillips Zoom in office whitening and i am in love with my results, Now i can smile for all my wedding pictures i am so glad i did my research and Chose Mamut. Dr Jovanka Z and Kristina P the coordinating manager were absolutely the sweetest, explained the whole procedure step by step, checked on me the whole entire 45 minutes, made sure i was comfortable and didn’t feel any pain. The ordination is soo clean (which matters) Very professional and they made sure i was happy with my results ( Shows that they greatly value their patients , i highly recommend Mamut Dentistry!!!!! No need to look for a new Dentist i found mine 🙂

Last week I went to see Dr. Zivkovic after a few friends highly spoken about her. At the first visit she did exam, x-rays, and cleaning (for a very fair price). I am 32 and this was the first PAINLESS, yet excellent, cleaning I’ve ever experienced in my entire life!!! (My gums usually bleed during this procedure, but with Dr. Zivkovic it did not) I went there again, this time to get my wisdom tooth removed and once again, great job and not only that but also follow up post-op over the phone in the middle of the night just showed how caring Dr. Jovanka is! Thanks for everything, will definitely come back and definitely refer to my friends!

Sheila F. from Bronx, Bronx, NY (Source: Yelp)


Dr. Zivkovic is a great dentist. She makes you feels at ease by explain the whole procedure ahead of time. She offers options and alternative treatments. She knowledgeable of all the latest technology in dentistry. My first procedure with her were derma filler and I was very happy with the results. She offers weekend schedule which is always helpful.

Doctor Jovanka is a great dentist. It was my first time visiting a dentist after a long, so I was a bit nervous about it. But doctor Jovanka is really experienced and good at her job and she made the whole process not painful at all. A friend of mine recommended me to her, since he have been going there for a while now and I’m glad for choosing her. Also, the prices are pretty reasonable.

After trying several dentists, I finally found the best in Astoria. Dr. Jovanka is a great dentist. The front staff is both professional and friendly. It is very easy to make an appointment and they are open on Sundays 🙂 and open late. Both my husband and I had a cleaning due from our insurance. We filled out the forms online and probably waited only about 5 minutes to see her. She was extremely thorough with her cleaning and took the X-rays on her own. On top of it she was very gentle and kind. The place is very clean too!. Highly recommend her.

Vanja O. from New York, NY (Source: Yelp)


Dr. Zivkovic is a gem! Her and her staff are professional, kind, friendly and honest! The crowns she did for me are beautiful! I love that I did not have to come for numerous unnecessary appointments – she knows our time is valuable so she does not waste it! Before Dr. Zivkovic did anything, Jelena (her staff member) explained clearly what was covered by insurance and what was my responsibility. In all my life I have never felt more comfortable at the dentists office! So happy I found her! Highly recommended!

Jefiimija N. from Manhattan, NY (Source: Yelp)


My dentist is awesome! Dr. Jovanka is an incredibly talented and skillful dentist….. The cosmetic work is truly artful and inconspicuous.Besides the basics- good care, a well-organized office-the staff is fun to talk to. You get the feeling that everyone who works there enjoys what they do. That’s a rarity in today’s world.She explains everything, doesn’t patronize you, acts like a person, and treats you like a friend. Though going to the dentist is noone’s idea of a good time, Dr. J makes the experience painless and worthwhile…. Lots of Hugs and Kisses, J.R.

Last 14 years I saw number of dentists because of my huge problems with multiple cysts I had on my teeth, and after numerous disappointments, I finally got across Dr. Jovanka and I was finally satisfied how she did her job and how my teeth looked like after the procedure! And not just me, I brought my 4 yrs old daughter as well to see her, and she loved her so much that whenever I say I am going to dentist, she asks if she can go with me 🙂 Strongly recommend Dr.Jovanka!

I have had such a big fear of dentists and Dr. Jovanka Zivkovic has made that fear dissappear. She performed an extraction painlessly, something that I’ve had to be sedated for in the past because of how great my fear was. So if you’re like me and avoid the dentist due to fear don’t worry she’s so great you don’t even feel like you’re having work done.
