About St. Johns Endodontics

St. Johns Endodontics provides dental care on Baymeadows Road in the Baymeadows area of Jacksonville, Florida. Root canal treatment removes infected or inflamed tissue from inside a tooth, cleans and seals the space, and allows the natural tooth to be kept rather than extracted. Its reputation for being painful is largely outdated — carried out under local anaesthetic, it typically relieves pain rather than causing it.

Left untreated, small dental problems tend not to stay small. A minor cavity that would have been a straightforward filling can progress to needing root canal treatment and a crown, and early gum inflammation that would have reversed with a good cleaning can progress toward bone loss around the teeth. Catching things early is generally the difference in both effort and cost.

Continuity matters in dental care — seeing the same practice over time means your history, X-rays, and any patterns in your oral health are already on file, rather than starting from scratch at each visit. That familiarity is part of what a regular dental home offers beyond any single appointment.

Dental anxiety is common, and most practices are used to working with nervous patients — through clear explanations of what is about to happen, a slower pace where needed, and sedation options for patients who want them. Avoiding the dentist out of anxiety tends to make eventual treatment more involved, not less.

Children benefit from starting dental visits early, generally by their first birthday or within six months of the first tooth coming through, mainly so they become familiar with the setting before any treatment is actually needed. Establishing that routine early tends to make ongoing checkups far less stressful for both child and parent.

Payment and insurance arrangements vary by practice and by treatment, so it is worth asking directly what is covered and what options exist for anything that is not, rather than assuming either way. Getting that clarified before treatment starts avoids surprises once it is underway. This page has the practice's contact details and full service list.

What services does St. Johns Endodontics offer?

How do I know if I need a root canal?
Common signs are lingering pain after something hot or cold, pain when biting down, a tooth that darkens, or a persistent pimple-like spot on the gum. Diagnosis needs an examination and usually an X-ray, since these can point to other problems too.
Is a root canal as painful as people say?
The reputation is largely outdated. The procedure is carried out under local anaesthetic and is usually no more uncomfortable than having a filling. The severe pain people associate with root canals is generally the infection beforehand, which the treatment relieves.
How can I look after my teeth between appointments?
Brushing twice a day with fluoride toothpaste and cleaning between the teeth daily covers most of it. Limiting how often sugary food and drink appear through the day matters more than the total amount consumed.

I was referred here for a possible root canal. Ended up having one the next day, as they were able to fit me in. I’ve had one before, but this was by far the easiest, painless root canal procedure! Would highly recommend Dr. McClure!

I’ve had some very difficult experiences with dental procedures in the past, but that was not the case with Dr. McClure and his staff. Dr. McClure did an outstanding job making sure I was completely numb and walking me through each step of the procedure. He was communicative and reassuring throughout the entire process, which made a huge difference for me. The staff was also incredibly friendly, helpful, and willing to answer any questions I had. What really stood out to me was that Dr. McClure personally called me at the end of the day to check on how I was doing and provided me with his personal number to contact him if I had any questions or concerns. That level of care and personal attention is truly exceptional and made me feel valued as a patient. I had a wonderful experience and would highly recommend Dr. McClure and his entire team, especially to anyone who has had difficult experiences with dental procedures in the past!

As you know, no one ever wants to go have a root canal!!!! 🩷🩷But my experience with St. John’s Endodontics and Dr. McClure and Renne was outstanding. They both are very professional but also very compassionate and caring to their patients. They explain the procedure and talk to you throughout the process. The receptionist was outstanding also. Dr. McClure followed up and called to check on me last night. It’s a good feeling when you know your doctor cares. I will highly recommend them to my friends and family.

I had a very positive experience with St. Johns Endodontics and Dr. Popkowski. They were able to get me in with a same-day opening, which I really appreciated. Stephanie was extremely polite and kind, and the office was very accommodating while I was trying to figure out how I was going to pay for the procedure. One thing to be aware of upfront is that they do not offer in-house financing, so you will need to have payment arrangements figured out separately. As far as the actual procedure, they were very attentive to my comfort and explained everything thoroughly so I knew what was happening. I was numbed properly and genuinely did not feel a thing during the procedure. The biggest downside for me was the financial impact. The endodontic treatment itself was nearly $1,800, and unfortunately I had already spent roughly another $1,800 to $1,900 on a crown that failed before I ended up needing this procedure. That made the total cost of dealing with this one tooth especially difficult financially. The earlier crown was not done by this office, so I do not hold St. Johns Endodontics responsible for that, but it definitely made coming up with the money on short notice much harder. Most importantly, I am now pain free. They fixed the problem I came in with, and that matters more than anything else. Overall, I felt well cared for, comfortable, and treated with kindness throughout the experience. I would definitely recommend them based on the quality of care I received.

100! I had an urgent need for a root canal (traveling out and state and country for two solid weeks). Dr Popkowski and staff fit me in immediately so I could continue to travel. ALL of the staff was amazing from checking in to making informed payment amounts. This team saved an important trip. On top of everything, the clinic even checked on me after hours to ensure I was doing well. 10/10 recommend.

I overcame the stigma of root canal through the excellent care of Dr McClure. Every step was explained before and during the procedure. Dr McClure has an ability to explain the procedure at the understanding level for an adult and for the anxiety level of a child. I had no pain except for the numbing needle. I can’t comprehend the skill that allows this finely detailed work up inside a tooth but that skill was apparent throughout the procedure. The assisting Nurse was also excellent. Dr McClure called to check on me the evening of the procedure and left his cell number if I had any issues. I can’t think of a reason not to have this done if you need it and I recommend you call St John’s Endodontics and ask for Dr McClure.
