I would give 100 stars if I could.
I have moved around a lot for work and have seen many different dentists, but NOBODY can compare to Dr. Jones. My nerves were high and I had a toothache that was 9/10 on the pain scale. From the moment I walked in the assistant was so nice and caring and let me know she was there for me and explained everything nice and thorough. When I met Dr. Jones, within two minutes I felt safe in her hands and my anxiety started to ease by the minute. She let me know her practice may not be able to fix my problem, but she was going to show the other two dentists in the practice my X-rays and would get back to me asap. She let me know right away I would absolutely not be in this pain over the weekend and prescribed me antibiotics and medication and said she would call me after the meeting with her colleagues and go over my options. Again- the more she talked, listened, and consoled me the better I felt. I have never met anyone, dentist Or otherwise, so calm and compassionate. My only complaint is that she isn’t a general dentist and I can’t see her more often.
She even gave me her cellphone number to let her know if I was still in any pain. WHO DOES THAT?
If you’re a nervous nelly like me, want honest and compassionate care, look no further.
Thank you Dr. Jones, you’re truly an angel.
Top notch staff and doctors. Was referred to this practice for two root canals and my worries were soon alleviated through Dr. Batsevitsky’s kindness and professionalism. Clean office with modern technology. The root canal procedures were pleasant and I was surprised at how painless and efficiently they were done at this practice. I would definitely recommend to anyone that needs to have a root canal done to go to this practice.
Report review
Dr. Jones’s bedside manner made the time I spent there fly by. Her approach to patients should be used as a model for all future dentists (general or specialists alike). I wasn’t just a patient on her to do list. She really tried to connect with me and ease my extensive anxiety around going to the dentist. There are not enough stars to show how good Dr. Jones and her staff are!!!!!!
Best possible provider for whatever endodontic issue ails you. From booking the appointment, to full course of treatment; it’s phenomenal.
No one sees an Endodontist because they want to, so if you need one, why settle?
Being treated by Dr. Jones has been an excellent choice for me. She made what would have otherwise been an anxiety filled experience not be so. I needed follow care and she was responsive to my needs. She went so far as to contact me on a Sunday after I texted her about my concerns. All my issues were prompt resolved the following Monday morning.
I highly recommend Dr Jones.
I want to thank you so much for the amazing job you did on my root canal on Friday. I was not looking forward to it, having had a bad experience in the past… but you took the time to listen to me and my concerns and that meant so much.
The entire procedure was pain free and you were able to finish it in one hour! You are a kind and caring person and I would recommend you to anyone needing your expertise.
Hooray for Dr. Jones and team! I can’t thank each of you enough for your thoughtful care and special attention in your various areas of expertise which blends into a wonderful team effort for those of us coming through the door as a patient.
Dr. Jones recently performed a root canal of my upper tooth; the procedure was flawless, and the experience was quite remarkable. Dr. Jones has impeccable skills; she is a born teacher as well as a superb endodontist as she explained the procedure while she worked on my tooth; this made me feel safe and secure; i.e., knowing that a gifted and compassionate person was at work. I felt no pain at all, and found Dr. Jones to be a superb doctor.
I met Dr. Bella Batsevitsky for my first visit and had an absolutely PAIN FREE root canal. I was terrified going in as it was my first experience with a root canal and the entire staff was amazing. They made sure I was comfortable throughout the whole process, it was so much easier than I ever imagined. Dr. Batsevitsky was so kind and reassuring. I would absolutely recommend her to anyone who may need a fantastic Endodontist.
Elizabeth Jones is the best endodontist with golden hands. If she says – there won’t be any pain- you can trust her 100%! Highly recommend
Premier Endodontics in Waltham is fantastic. I saw Dr. Kathleen Molgaard yesterday and she is super skilled, super kind and made the experience so amazingly comfortable for me. Not enough stars to compliment her fully! Her assistant/hygienist, Maria was great, also! Staff is so friendly and the office is meticulous. Very impressive!!
Dr. Jones and her staff provided the best extended dental service I have ever received. Dr. Jones made the experience of a two part root canal as painless and as comfortable as it could possibly be given the nature of my discomfort. She was upfront with each step from beginning to end. She consistently checked in with me to make sure I was alright. Dr. Jones’s bedside manner made the time I spent there fly by. Her approach to patients should be used as a model for all future dentists (general or specialists alike). I wasn’t just a patient on her to do list. She really tried to connect with me and ease my extensive anxiety around going to the dentist. There are not enough stars to show how good Dr. Jones and her staff are!!!!!!
Premier Endodontics and Dr. Molgaard were phenomenal. I was referred with high recommendations from my primary dentist and his positive expectations were true. They got me in short notice for an infected tooth and Dr Molgaard performed the root canal with precision, pain free (less than any filling) and very sociable and good bedside manner. The music was good too! High caliber, friendly, best of their trade, highly recommended!
“Hi Dr. Jones!! Omg so are you ready for this “is this normal” question? Since the lidocaine wore off yesterday, I have literally had zero pain, zero soreness, zero tenderness, my tooth feels solid as a rock (it used to feel a little loose before the retreatment), and my swelling is almost completely gone!
You are seriously an endodontic wizard. I cannot thank you enough for everything. I feel totally awesome.
You’re the coolest! I am so happy I decided to get this done with you. Don’t tell anyone this, but I think I might have actually had a little fun.”
I’m so grateful to Dr. Bella and Dr. Jones for making my treatment painless and fast. Assistants and staff are amazingly kind and accomodating. The dental office is so pleasant (Great music)…. Dr. Bella has a good sense of humor. Thank you very much for your service!!!
I am a huge baby when it comes to any dental work. Dr. Jones is amazing. Gentle, funny, caring. Truly the best. She just told me about seeing Brian Wilson at Tanglewood to distract me. The BEST!
I am so so deeply thankful to this practice for booking a same-day root canal appointment for me when I was in agony and unable to sleep the previous night. I couldn’t imagine waiting one more day to get the procedure done. They were able to see me within 2 hours of me calling and it was painless as soon as the novocaine set in.
Dr. Jones has magic hands! I’ve heard some horror stories about root canals. Mine was easy and painless. Dr. Jones has a great manner to boot. They got me in the chair asap despite the covid shut downs and made it a stress free experience.
