Had a great dental cleaning yesterday with their dental hygienist. She was thorough, gentle, and made sure I was educated on everything. I then went back to meet with Dr. Beckwith, who was very compassionate and helped point me in the right direction to get help for a very rare oral issue I have had for almost two decades. I felt like I was finally getting some real answers and actual help! I am very thankful.

I have been going to Dr. Beckwith my entire life. From braces and cavity fills in my teens to root canals and gum grafts later in life, I have had nothing but great experiences. The entire staff is very professional and the hygienists always do great work. I drive 2 hours round trip for my dental care and it's worth it. The service is always pleasant and friendly. The work performed is always above average. Highly recommend!

The experience at the Cornerstone Dental was very bad, when I was making an appointment the first thing they asked me was the credit card number and the three security digest, I paused, and asked myself, why did they want my credit card number when I did even get the service yet? A couple days later, there was an unknown charge to my account, it was a small amount like $40. purchased online. Well, coincident?

Right away I called the credit card Co. and took care of the unknown charge. My procedure was a chipped tooth. I went for my appointment, they asked me for the insurance card, I forgot it at home, OK the staff is going to look at it. The assistant Dentist took a picture of the tooth, and told me to come back for the procedure, again I asked myself. Why? Well, so they can charge again for the insurance. After, before the next appointment, they gave me the full bill to pay because the staff could not find the number on my insurance.

Then I knew his place it's not for me. I paid the bill, and when I was goin home called the insurance, with no problem, gave me my card number, called the receptionist, and got my money back. Long story short, I went to another dentist the same day, the dentist took care of my tooth. The only time you give the three security digests, it's when you buy online. I do not trust this place.

I had a molar extracted by Dr Beckwith and then a few months later an implant installed in it's place. Had essentially no pain after each procedure. A little bit of pain on the day of the procedure but even that little bit of pain was gone the next day. Clearly he knows what he's doing.

Highly recommend our dentist's office! Everyone here is professional, friendly and efficient. They are mindful of your appointment time and any wait is minimal. My husband and I have been long time patrons here and it's really the best in this area by far! Anyone looking for a great family long term dentist will be happy and satisfied by everyone they come across at the office!

The best dental care! Dr. Beckwith combines expertise, precision, talent. He really took his time to explain my conditions with me as well as my treatment options. I've been going with them for a very complicated process (dental implants). The staff is very friendly and professional. I've never had to wait more than a few minutes when I arrive on time for an appointment. The office is modern and very clean. I highly recommend Cornerstone Dental.

Cornerstone Dental provides unmatched excellent quality service! High level of skill and professionalism keeps me and my family returning for all our dental needs year after year. Cornerstone is a great service provider for all ages. Our child started there as a toddler, received orthodontic services as a teen and today, standard adult services. Top notch customer service and genuine care for clients.

They are good to their employees as seen by the loyalty of their staff-I've been a client for close to 25 years and to this day have the pleasure of seeing the same dentist and hygienist upon request. The office staff are super organized, thorough and friendly too. All around great practice; highly recommended.

I've been using Cornerstone Dental for many years as a resident of Hillsborough while raising my family and from my current location in Bridgewater. The dentists, hygienists and staff are excellent. They make you feel so welcome, comfortable and at ease during your visit. I highly recommend their services.

Every experience I and my family have had here has been exceptional. This is the first Dentist that my 2 year old son has ever been to and he is excited every time to go and see the Dr and staff here at Cornerstone. I have been here many times during the past year due to invisalign and every single time I have experienced the professional and caring people here. I'd recommend to anyone looking for a great, reliable, professional and caring Dentist practice in the area for the whole family.

Currently in the process of receiving an implant. So far the procedure has been totally pain free and is progressing smoothly. Dr Beckwith and his staff is always courteous, caring and professional. I would highly recommend Cornerstone for your dental care.

Cornerstone Dental was referred to me by a close friend who shared that their experience there was great. My reason for needing to visit Cornerstone Dental was because I was in a lot of discomfort as a result of crown work which needed proper attention. I am extremely pleased that I followed the advice of my friend and visited Cornerstone Dental. The entire experience was exactly what I would expect from a Dentist and his staff.

They are extremely professional, always courteous and smiling. They made me feel like I mattered and I always knew that they were sincerely concerned about the work being performed. Their facility is always clean even prior to COVID19 and during this season they took extra care ensuring that all their staff and patients were kept safe. Furthermore Dr. Beckwith didn't rush my procedure and took the exact time and process required to fulfill my dental needs which was important as this resulted in me not experiencing any further pain and discomfort like I had in the past with prior dentists.

Everything he told me to expect was what I experienced and I greatly appreciated his honesty and insight on what it took to complete the work needed on my teeth. In most cases I like most people do not look forward to dentist visits however I have to say honestly I never minded and actually looked forward to my next visit each time because I knew how I was going to be treated and that I was being taken cared of and most of all that the work being done was leading to closure for the work I needed performed.

I have recommended Cornerstone Dental to several people already and will continue to do so. I cannot thank Dr. Beckwith and his entire staff enough for the great work, the consideration, professionalism and courtesy I was shown each time. They are sincerely dedicated and simply great people. Thank you - Jean Paul Reece
