I live in Cambridge but have been driving to Stoneham for 12 years now because I doubt I could find another dental practice as good as Dr. Petrelli’s. Not only do I have complete confidence in her, but it’s such I pleasant place to be. Everyone else, from the desk staff to the hygienist is warm and welcoming. In those 12 years the same people have continued working there.

Dear Dr. Petrelli and Staff, I have been coming to Stoneham Dental Care for over 40 years and have always had a very good experience. The service I have received has always been professional, state of the art and compassionate. Although I have not always been comfortable sitting in the chair (who is?), nevertheless I tell others that the dental work I have had done has always been painless. On my last visit, observing the decor and the friendly atmosphere, I thought to myself, “This is like having dental work in my own home. I know and trust everyone here to do their best for me.” Peace, Rev. George Szal, S.M.

I’m a big baby when it comes to the dentist..petrified! From the moment I walk in every one is so sweet. I get sedated every time I get work done and highly recommend it if you are afraid. Thank you to everyone who worked and still works with me. I cant thank you all enough!

Jim P. from Andover, MA (Source: Yelp)


I’m not dentist friendly at all and prior to going to Stoneham Dental Care I had avoided the dentist for and embarassingly long time. From the minute I walked in the staff went out of their way to put me at ease.  For those with the negative reviews, there is more than one dentist at this office and Dr. Petrelli is OUTSTANDING.  SHE is incredibly knowledgeable and personable and more importantly has NEVER caused me any major discomfort when working on my teeth.  I have to say the assistants are great too.  Especially Maria.  I have referred this practice to many and will continue to do so.

I have been to SDC (Stoneham Dental Care) for at least 7+ years, and I must say this is one of the most comprehensive Dental offices I have been to. The location and parking are convenient. The teams of doctor- Christina, hygienist-Nancy and administrators-Nancy & Amanda are superb, they’re experienced, knowledgeable, professional and courteous. On top of my regular cleaning, I had also many crowns, root-canal done in this very same facility. The office hours are exceptionally flexible. The reception area is inviting with comfy sofas and plenty of free beverages and reading materials. The rooms are clean with comfy dentistry chairs ( one is particularly comfortable with memory-foam I think). I would definitely recommend SDC to anyone who lives in the area or even a little way outside of the area, it is easily accessible from route 95.

Was motivated to write a positive yelp review, as my husband and I have been receiving excellent care here for approximately six years. They have always been very thorough and respectful and cost-conscious. It seems like most of the negative reviews pertain to Dr. Fitzgerald, who is now deceased. Neither of us had any problems with him, but we were equally often treated by Dr. Petrelli.

Jory A. from Cambridge, MA (Source: Yelp)


I have been going there for years.  All of the staff has always been incredibly compassionate and gentle. For someone one who gets really anxious with even the thought of being in pain, they are amazing for making the whole experience non-traumatic.  They have converted someone who used to dread going to the dentist into someone who actually looks forward to it!  I would recommend Dr. Mary Petrelli to any one with any anxiety about seeing a dentist.

So far I have been for a new patient visit and to have cavities filled. Everyone at this practice is friendly, professional, and most notably super patient with babies like me who have a lot of anxiety surrounding visiting the dentist. My fillings were done at my pace and without much discomfort. Glad to have found a place like this.

We were looking for a new dentist since moving out to the suburbs. The place itself is very clean and professional looking, with several work stations throughout. Their working hours are quite long, which allows great flexibility in adjusting your appointment to your work schedule. Jenn, the hygienist, was wonderful and very gentle. Dr. Petrelli was also very nice, even though I only saw her for a few minutes (since I didn’t have cavities, which is a good thing!). We’re definitely making this our permanent dentist from now on.

Age A. from Medford, MA (Source: Yelp)


Stoneham Dental Care is THE abolute best practice I’ve EVER gone to. I have a fear of the dentist and they offer sedation dentistry. By using that service, I have been able to keep up with my dental health over the years without fear/pain. The staff and providers are friendly, caring and very easy to talk to. I have recommended them to many people with total confidence that they will take the best care of anyone I send their way. Love, love, love them!

Kathleen T. from Haverhill, MA (Source: Yelp)


The whole staff at Stoneham Dental is amazing!  I have been going here for 7 years and everyone, from the girls at the front desk, to Nancy, my hygienist to the Drs themselves are friendly and courtes.  Before any procedure has to be done they go over what is covered by insurance and what is your responsibly.  I have recommended Stoneham Dental to a few people and they gave high praise for praise for the staff also.  Keep up the good work everyone!!

I have been going to Stonehame Dental for several years and I get exceptioal dental care from Dr. Petrelli and Maria. They are always on time and are very thorough. I am very particular about my dental care and would highly recommend them. Bonus is the friendly and helpful staff at the front desk!

Cory A. from Stoneham, MA (Source: Yelp)


I have had only the most positive experiences at Stoneham Dental Care. Many members of my immediate and extended family are clients and have only wonderful things to say. The staff is always warm and friendly (especially Maria) and show real care and concern for my oral health. Very gentle and affordable. I will continue to use and highly recommend Stoneham Dental Care!

Patrick C. from Stoneham, MA (Source: Yelp)


I was seen at Stoneham Dental Care after my girlfriend referred me to that office. She had veneers on all of her front teeth with Dr. Petrelli and was so pleased with everything. I am now a patient of Dr. Fitzgerald because I an a dental phobic and he specializes in sedation. I have had a few visits now and have also been please with everything from the staff to the beautiful office. I am so happy I finally found a dentist I like.

Terri J. from Middlesex, MA (Source: Yelp)


I was seen at Stoneham Dental Care for an emergency, they were able to see me within a few minutes even though I had never even been there. The staff there were so helpful. I was nervous I was going to have to lose my tooth from the accident I had over the weekend. They were able to save my tooth, Thank God! I can’t thank Dr. Fitzgerald and his team enough. I will be going back very soon!

Laura S. from Reading, MA (Source: Yelp)


Stoneham Dental took all the necessary steps prior to patient care in regards to this coronavirus. As for their reputation in dental care I feel they are the best at welcoming and making you feel comfortable which to me is first and foremost. The staff is very friendly in all aspects of their position. I’ve been to many dentists in my life and Stoneham Dental has been my number one for the last ten years! Keep up the great work

Wendy F. from Middlesex, MA (Source: Yelp)


I completely  disagree with your comments Joanne, I give that establishment  5 stars.   I myself am not dentist friendly either.  My experience at Stoneham Dental was nothing but positive.  The Dr.’s were comforting and attentive.  They answered any and all of my questions.  The staff was there at all times to help during my treatment.  The team helped me get over my fear of dentistry and put me at ease.  I have referred family and would recommend them to anyone.

Charlotte F. from Winchester, MA (Source: Yelp)


I have been going to stoneham dental for 30+ years and in that time they just continue to improve in all areas of the business. First of all they are a Family business which is rare. From the front desk to the hygienists, assistants, doctors they all treat you with respect and family. They provide many services which they will make you aware and explain but in no means pushy about it it.  Stoneham dental is very committed in treating each of their patients with dignity and respect, and of course like Family.

This was the best dental experience I’ve had. I am not a fan of dental work in general. The staff was excellent and made me feel welcome and cared for from the moment I walked in. I was comfortable, relaxed and calm my entire appointment. The follow up was impeccable and personable. I can honestly say I’ve never been happier with my smile. Thank you. I will never go anywhere else!

Elizabeth S. from Stoneham, MA (Source: Yelp)


This was my first time back to this dental center since the beginning of the Covid-19 pandemic. I was impressed by how careful they seemed in terms of infection control measures, and feel that I got excellent care from Maria this week when I went for my periodic tooth-cleaning! I am happy to give them a “five-star” review!

Geoffrey M. from Stoneham, MA (Source: Yelp)


I am a new patient with Stoneham Dental. I am extremely impressed with the facility (spotlessly clean), the people who actually take time to learn about you and what is unique to you as a patient. Nancy was my first contact and she is friendly, warm, patient, personable — and extremely knowledgeable. I never had such a thorough dental examination with state of the art equipment. From the entrance way to the dental chair the office is spacious and meticulously cared for. I would recommend it without hesitation from my first visit. Outstanding! For years I observed it from Main St but never saw the parking sign and presumed parking was limited. Parking is in fact spacious.

Jen Norford (Source: Facebook)


I would recommend this place 100%, very professional, efficient, friendly and thet really care about your oral health. After assist you, call you by phone to see if you’re ok. I really love it

I needed to find a new dentist about 6 years ago and my friend suggested Stoneham Dental. I am very happy I tried them and have been with them ever since. I Have had a lot of dental work done. Dr. Petrelli is the best, a great dentist and very caring. Her assistant Candice is excellent and Nancy my hygienist is fabulous. Everyone that works in the office is so personable, they always make you feel comfortable.

Elena Mancini (Source: Google)


Highly recommend! I have been going here for 18 years. Nancy is my dental hygienist and she is excellent at her job, super friendly and gentle. Dr. Mary Petrelli, Dr. Christina Orchanian, Dr. Marc Pearlstain, and Dr. Janna Melzer – all are highly skilled, professional, friendly, and I refer everyone to them. The office staff are prompt, informative and welcoming. Nancy in the office always remembers me! (there are 2 Nancy’s) When I first came in I had 15 cavities! Bad genes. I could really go on about how much they have helped me. I can smile in confidence now and it is a great feeling I have a place I can trust with my dental health.

Gavin G. from Woburn, MA (Source: Yelp)


I am amazed with the friendliness and professionalism of the staff and doctors. The moment I first walked into their office, after many years of not seeing a dentist, I felt welcomed. The experience has changed my views  and habits about dental care. I no longer fear the idea of going to see the dentist. They really live up to their words and take care of you. I highly recommend this office for your dental needs.

Christine H. from Dedham, MA (Source: Yelp)


Stoneham Dental Care is great. So great that even though I’ve moved an hour away, I still make the drive for my regular cleanings and whenever I need care. The staff is friendly and go out of their way to make me feel comfortable. I know it’s hard to find a good dentist that’s affordable and I would highly recommend Dr. Petrelli and her team.

Sally G. from Boston, MA (Source: Yelp)


I needed a dentist (sigh) and a friend of mine had raved about Stoneham Dental. I was still hesitant to try them because I saw the mixed reviews, but there were only 3 reviews posted in total and I’ve noticed in the past that the type of people who post on yelp are usually the small sector who are really pissed off. Sooo I went with my friend’s advice and gave them a try. Loved them! I was squeezed in for a cleaning the week I called (they have some nights of the week with later, after work appointments!). The staff was friendly, smart, and I waited less than five minutes from walking in to being in the chair. Especially for a place with the warmth of a family business, this place has state of the art equipment. Dr. Fitzgerald showed me my electronic x-rays on a screen next to the chair and talked me through areas he was looking at. He also recommended I wait to have any procedures (I have a bit of receding gum lines), until I really needed them, and in the meantime to switch toothpastes. I got a great cleaning, piece of mind that I could wait on further procedures, and was out of there in 35 minutes= 5 stars.

Patrick C. from Lynn, MA (Source: Yelp)


Exceptional value, highly recommended. Whoever said Dr. Fitzgerald and the rest of the marvelous staff at Stoneham Dental are greedy are out of their minds. I have seen my share of pricey dentists that don’t deliver value. Stoneham Dental is not one of them. What you will receive is value and exceptional service from the staff. I had fillings, temp crown, and gum removal done in one appt. Sounds like a nightmare, however Stoneham Dental uses state of the art technology to offer a painless experience. The dental assistants were well informative and friendly. They show concern about patient’s comfort and well being. My smile is forever transformed and I have Stoneham Dental to thank for it. They are also located very conveniently on Main St. Stoneham Dental is upfront and give it to you straight. There’s no hidden costs or overcharges. Compared to other family dentist practices, Stoneham Dental’s pricing is moderately aggressive and offer flexible payment options. Give them a call, you won’t be disappointed. 🙂

This place is truly amazing.. the staff is warm, caring, friendly and truly care about your well being. I have always had major anxiety going to the dentist but they ease all of those fears the minute you get there. They use cutting edge technology and are always looking to give you the best care. I can’t say enough good things about Stoneham Dental…

Rich Afrikian (Source: Google)


Excellent service and wonderful staff. I moved here when my dentist of 10+ years retired. I had come for a 2nd opinion on major work that i do not want!!!!!!!! Well-the staff are wonderful and friendly, the Docs are professional and personable-friendly and all is good. Equipment is modern and like new and the facilities are -brand new-. I am pleased and their location is great too-

Ryan H. from Stoneham, MA (Source: Yelp)


I thought that I would never find another dentist office that was as good as the one I grew up with.  Stoneham Dental exceeded my expectations!  The office is kept clean and the staff is always friendly.  The best part is that they accept my insurance!  My last dentist was in a small location and was using outdated techniques and tools for the cleaning.  Not Stoneham Dental!  All new equipment!  As long as I am living in the Stoneham, MA I will be going to Stoneham Dental!!

Meg F. from New York, NY (Source: Yelp)


After being told I had 6 cavities to fill while living in a different state, I went back to Stoneham Dental Care for a second opinion. I couldn’t believe it. My appointment for a regular cleaning ran right on time. Dr. Fitzgerald and Dr. Petrelli both came in at the end of my cleaning for an exam, and I was told honestly and directly that I have my teeth look great, but they will keep an eye on a few possible trouble areas areas to make certain that nothing gets worse. There was absolutely no need to fill 6 cavities, let alone 1. I felt extremely relieved knowing that I could trust them. Dr. Fitzgerald was excellent and assured me that he will keep an eye on any decay, but nothing more than sealants are in the near future. I could not recommend Stoneham Dental Care more – they are everything you want in dental care.

Kenneth N. from Wakefield, MA (Source: Yelp)


Stoneham dental has been caring for my whole family for many years, and the the service they have given us is second to none. Dr. Petrelli is a perfectionist and it shows with the movie star smiles she produces. Whether it is cosmetic work, routine cleaning or a dental emergency, you can count on the team at Stoneham dental to do the best job possible. They are also cost-conscious, and will form a long-term plan which makes the most economic sense for their patients in the complex world of dental insurance.

Richelle Murray (Source: Google)


Until I found Stoneham Dental, I had never been to a dentist that seemed to care that I was scared out of my wits while receiving treatment. The people at Stoneham are extremely kind and patient. They explain everything before it happens, even simple things. If even just getting in the chair is a problem, they will help you every step of the way. If the thought of going to a dentist scares the crap out of you, have a friend call and get you an appointment. (because I know you aren’t doing it for yourself) Get in the car, or get someone to drive you and head to Stoneham. They can help you, Teeth are important, don’t be scared!

Christine L. from Stoneham, MA (Source: Yelp)


I wan’t to start by saying that Dr. Fitzgerald, the dentist who all these bad reviews seem to be about, recently passed away. I never met Dr. Fitzgerald so I can neither confirm nor refute what previous reviewers have said. But I can say if you’re steering clear of this place because of the poor reviews, don’t. I was totally impressed! I recently went to Stoneham Dental for the first time. I don’t have dental insurance and needed a cleaning. They’re currently running an $80 special for a cleaning (incl. X-rays if needed) and full oral exam. I figured I’d take advantage of that offer despite the terrible reviews since I was just going for a cleaning. I was able to schedule the appointment five days from when I called. That might have something to do with the terrible reviews but it worked out for me because I don’t like to wait. I arrived five minutes late and the very pleasant office staff assured me that it was not a problem. I started filling out my paperwork in the beautiful waiting room where they have a Keurig and a little fridge with bottled juices & water for the taking. Before I was even finished filling out the paperwork, the hygienist, Nancy, came to get me and said we could finish filling it out together. Nancy took me into the exam room, which was nice & clean. She started talking to me like we were old friends, which made me feel incredibly comfortable. I have some anxiety around going to the dentist so her bubbly personality and genuine, down-to-earth manner was welcomed and greatly appreciated. We chatted a bit while finishing up the paperwork so by the time she asked me to open my mouth I was completely relaxed. Nancy explained everything she was going to do before she did it. She told me how things were going to feel and sound and made sure I was comfortable with it before putting anything in my mouth. She was very thorough–she spent at least 30 minutes cleaning my teeth and examining my gums and mouth. I didn’t get the feeling that she had to hurry up because other patients were waiting, which I’ve experienced at many medical/dental appointments in the past. Nancy went over my X-rays with me showing me a few places the dentist would probably have to check further so I knew exactly what to expect from the dentist before she even walked in the room. The dentist, Dr. Petrelli, was just as nice as Nancy. She introduced herself and, like the hygienist, told me what to expect before she did anything to my mouth. She explained that I should have a few (very) old fillings replaced and a couple new cavities filled. She also told me there was nothing dire that needed to be done immediately and she could do a little at a time over the next year or so. When I got back up to the front desk the secretary had a treatment plan printed out. Because I was the only person there, she sat with me in the waiting room and went over everything with me. The $80 charge was just that–an $80 charge–no hidden fees or tax or anything like that. She told me that Dr. Petrelli would fill two teeth on my next visit and in order to book the next visit they require a deposit (25% of the cost for the visit). Since I’d just gone in to take advantage of the cleaning special and I don’t have the money to get any of the work done right now, I told her that I didn’t want to book the visit yet. She very pleasantly said that was okay and told me to call when I was ready. I felt absolutely no pressure. When I’m ready to get the work done I will definitely go back to Stoneham Dental. They were great. I highly recommend them. And if, like me, you don’t have dental insurance, why not take advantage of the $80 cleaning special and check them out for yourself? I will update this review when I get the fillings done.
