About HJ Ludington DDS

Based on Lafayette Road in Portsmouth, New Hampshire, HJ Ludington DDS is a dental practice serving the area. General dentistry covers the routine and restorative care most people need most often — examinations, cleanings, fillings, and preventive checks that catch problems while they are still small and inexpensive to treat. Regular attendance, roughly every six months for most patients, is what makes that early-catch approach actually work.

Beyond any single treatment, most dental visits start with an examination — checking for decay, reviewing the gums, and looking at existing fillings or crowns — often alongside X-rays where there is a reason to look between or beneath teeth. That groundwork is what a dentist uses to explain any findings and set out next steps before you leave.

Routine attendance, roughly every six months for most people, is what actually keeps small problems small. A lot of decay and gum disease develops without any pain in its early stages, which is why regular checkups matter even when nothing seems to be wrong, rather than only booking an appointment once something hurts.

A first appointment at a new practice typically covers a full examination, a review of your dental and medical history, and a professional cleaning, with X-rays if you do not have recent ones. It is also a reasonable time to raise any longer-term concerns, cosmetic or otherwise, so they can be factored into a plan going forward.

Day-to-day oral health still comes down to the basics between visits — brushing twice daily with fluoride toothpaste, cleaning between the teeth, and limiting how often sugary food and drink appear through the day matters more than the total amount eaten at once. Regular professional care is what catches whatever those habits do not.

Digital X-rays are a routine part of dental care because they show what a visual exam alone cannot — decay forming between teeth, bone loss below the gumline, and how developing adult teeth are positioned in children. They use a low radiation dose and are taken on a schedule matched to individual risk rather than at every single visit.

Such a wonderful practice! The staff is friendly and Dr. Ludington did a fabulous job with absolutely no pain during my procedure and very little pain after. I would highly recommend!

Doc Ludington gets the point quickly and communicates problems directly. No beating around the bush, no sugar coating; tells you how it is. Very knowledgeable doctor. Shawn (or Sean) at the front desk very welcoming, friendly and willing to answer questions or help you if needed. Elizabeth and Kristen both easy to talk with. Both of them made sure I was comfortable and informed on all procedures. Lastly, Jamie... I called Jamie with no idea how to proceed with getting an appointment. After a lot of confusion with my DoD dental office, Jamie helped get me to where I needed to be. If you're looking for a professional Doc with a helpful staff this is the place.

I had an excellent experience at New England Endodontics and Implantology. The doctor was professional, knowledgeable, and took the time to explain everything in a calm and reassuring way. The entire staff was kind and welcoming, and the office had a very relaxing atmosphere. They made what could have been a stressful visit a very comfortable experience. I highly recommend them!

Dr. Ludington misdiagnosed my tooth, which resulted in two root canals. DO NOT GO HERE! Read the other negative reviews—what they are saying is 100% accurate. He is rude, condescending, and rushes appointments without any conclusive evidence to get patients in and out as quickly as possible so he can move on to the next one. My primary dentist referred me to Dr. Ludington for a same-day procedure and warned me, "He's grumpy." I was grateful that he could get me in and thought maybe they were exaggerating. They weren't. Dr. Ludington was abrasive and dismissive. The staff seemed miserable (except for the billing lady) and lacked empathy, personality, or enthusiasm—not helpful when you're already anxious about being there. I had an appointment at 11:00 a.m. to evaluate tooth #14, but the cold test was inconclusive, and I was sent home to let the ibuprofen I had taken earlier wear off. I returned at 3:30 p.m. and told Dr. Ludington that I did not think tooth #14 was the problem and believed it was tooth #15, as that tooth had caused me issues in the past. He performed the cold test again, and the results were once again inconclusive. There were varying responses between teeth #14 and #15, and I explained that the test did not cause pain—it simply felt cold. Between visits, I had done some research on root canals and asked about getting a CBCT scan. Dr. Ludington responded that "X-rays are the worst diagnostic tool" and suggested I might need two root canals. That didn't sound right to me, but he was the specialist, so I trusted his judgment. Fast forward: he performed a root canal on tooth #14, and a week later I was still in just as much pain. I returned for treatment on tooth #15—the tooth I had originally suspected—and it was found to be full of infection. It began draining as soon as it was drilled. I then had to take antibiotics for the following week to treat the infection. The key point is this: had proper diagnostic measures been taken and a CBCT scan performed, the infection in tooth #15 likely would have been identified before any work was done on tooth #14. In summary, Dr. Ludington rushed my initial appointment and misdiagnosed a tooth that was otherwise healthy. As a result, I underwent two root canals, endured weeks of pain, and ultimately needed crowns on both teeth. In total, I spent over $7,000 throughout this ordeal. To make matters worse, the infected tooth that was eventually treated appears to be failing, as I have experienced a persistent ache since the procedure. Save yourself the time, money, and pain, and go elsewhere. Based on my experience, you are unlikely to receive the level of care and attention you deserve and may find yourself dealing with the same frustration and regret that I have.

Dr. Ludington was fantastic. Another dentist told me I needed a root canal and Dr Ludington looked at my xray and said I definitely did not need one and my tooth was fine. He could have just done a root canal I would never have known but he was very honest and I highly recommend this Doctor. The staff was also very friendly and helpful this is a great dental office.

Excellent practice. I have had 3 implants a 2 root canals over the years. The staff is very helpful and prompt with billing questions and appointments. Dr. Luddington is very skilled and can diagnose issues that normal dentists can not handle.

Dr. Ludington did a great job. I was a difficult patient due to a disability but the entire staff were kind and patient with me. The did everything in their power to accommodate me, and all worked out well. It was actually a good experience.

I visited Dr. Luddington’s office for root canal treatment and had a very positive experience with Dr. Luddington and the clinical staff. They were professional, helpful, and resolved my issue. Unfortunately, my experience with the billing process was the opposite, and patients should be aware of how it’s handled. Earlier this year, I made a partial payment during a visit and clearly communicated that I was working on paying the remainder. My plan was always to pay the balance on 4/17/26. Despite this, my account was sent to collections the same week I intended to pay — I began receiving collection calls on 4/14. I never received a single phone call or email from the office itself before this happened. Throughout the year, I received only two billing notices: one older notice and one that arrived just about a week ago. These were the only communications I received from the office. Had they reached out even once by phone or email, they would have known I was planning to pay this week. When I went in on 4/17 to pay the balance in full, I learned that an additional $100+ fee had been added due to the involvement of a collection agency. This was frustrating and felt unnecessary given that I had already communicated my intent to pay. Later that same day, I received a mailed notice stating that there had been “repeated calls” and “no attempt to pay.” This does not reflect my experience. I made a partial payment earlier this year, and I did not receive any calls from the office prior to the account being sent to collections. Dr. Luddington provides excellent clinical care, but based on my experience, I strongly recommend that patients be cautious and proactive when dealing with the billing department. Communication was limited, timelines were not handled reasonably, and the written statements I received did not match the actual efforts I made to pay my balance.

Just had my stitches removed and it was short and easy - had to wait 15 minutes in the chair but once the Doc arrived, we were out in 5 minutes .A little short with instructions after but nurses always willing to answer any questions

I had a great experience with Dr. Ludington. He is clearly very skilled and knowledgeable in endodontics. What I appreciated most was how straightforward he was, explaining the care plan clearly, and the reasons behind treatment recommendations. The procedure itself was surprisingly pain-free in spite of a serious infection, and the pricing felt very reasonable for the level of care I received. Professional, efficient, and genuinely patient-focused. I wouldn't hesitate to return or recommend him to anyone needing root canal treatment.
