Tooth pain that will not let you sleep, eat, or focus on anything else is your body signaling that something is seriously wrong inside the tooth.
For Jacksonville and San Marco patients dealing with a deep infection, a cracked tooth, or severe decay that has reached the pulp, root canal therapy offers the most direct path to lasting relief and, in most cases, it means keeping the natural tooth you were born with. At JAX Dental Studio, part of our restorative dentistry care, we approach root canal treatment as an act of preservation, not just a procedure to get through. Dr. Charles Poblenz, DMD brings a calm, patient-centered approach to every case.

Root canal therapy treats the soft inner tissue of a tooth, called the pulp, when it becomes infected or severely inflamed. Deep cavities, a cracked tooth, repeated dental procedures on the same tooth, or physical trauma can all allow bacteria to reach the pulp. Left untreated, the infection spreads to surrounding bone and can threaten adjacent teeth. Research in PubMed Central shows root canal success rates have improved significantly with modern techniques.
Removes infected tissue instead of just masking the discomfort.
Preserves bite alignment and the jawbone support replacements cannot fully replicate.
Stops infection reaching surrounding teeth and bone before the problem grows.
So you can bite, chew, and speak comfortably again.
Catching these signs early gives you the best outcome and prevents the infection from spreading. Our blog explains when you need a root canal in more detail.
A tooth that needs root canal treatment does not always hurt. Some infections progress quietly, which is why routine exams remain important.
While tooth extraction is sometimes the right decision, preserving a natural tooth is preferred when it remains a viable candidate. If extraction is genuinely necessary, Dr. Poblenz will walk you through every replacement option.
Our guide to what happens during root canal therapy walks through each step.
Dr. Poblenz reviews digital X-rays to map the canal and confirm the infection. The area is fully numbed and a protective dental dam keeps it clean and dry.
A small opening is made in the tooth, the infected pulp is removed, and the canals are shaped and flushed with an antibacterial solution.
The clean canals are filled with a biocompatible material and sealed, and a custom dental crown restores full biting strength.
For upper back teeth, mild sinus pressure or minor drainage in the days after treatment is normal. If symptoms last beyond a week, contact our office.
The pain you feel before the procedure, from the infection itself, is what hurts. The root canal removes that source, and with modern local anesthesia the procedure is routinely compared to getting a dental filling.
Local anesthesia numbs the area completely before treatment starts, which is why root canals hurt so much less than people expect. Some mild sensitivity afterward is common.
Severe pain or facial swelling from an infected tooth calls for treating a root canal as a dental emergency rather than waiting. Delay risks losing the tooth.
The tooth can become infected again when bacteria remain inside it or find a way in afterward. That is how a root canal gets infected again.
Roots of the upper molars and premolars sit just below the sinus, so a sinus infection from a failed root canal is possible. The risk applies mainly to upper back teeth.
How long a root canal lasts is shaped by the crown placed over the tooth and by routine dental visits.
Yes. A fixed dental bridge replaces an extracted tooth and keeps neighboring teeth from shifting into the gap.
Dr. Poblenz was born and raised in Jensen Beach, Florida, and earned his Doctorate of Dental Medicine at the University of Kentucky College of Dentistry in 2015 before returning to Jacksonville to begin his career. His approach rests on one principle: an informed patient is a comfortable patient.
Before any root canal, he reviews the X-rays with you, explains exactly what will happen, and answers every question without rushing. He and his team exceed Florida’s continuing education requirements every year.

Not the way most people expect. The procedure is performed under thorough local anesthesia, and its goal is to eliminate the pain caused by the infected pulp, not to create new discomfort. Most patients describe the experience as comparable to getting a standard filling, and any mild soreness typically resolves within a few days.
Most root canals are completed in a single appointment lasting approximately 60 to 90 minutes. Molars or cases with unusually curved canals, significant infection, or multiple canals may require a second visit. Dr. Poblenz provides an accurate time estimate after reviewing your digital X-rays.
In most cases, yes. A dental crown is placed afterward to restore full biting strength and protect the treated tooth, and timely crown placement is one of the most important factors in long-term success.
Most patients return to normal activities within a day or two. Mild sensitivity is common for a few days, and for upper back teeth, minor sinus pressure or drainage can occur as the area heals. If symptoms last beyond a week, contact our office.
In some cases, yes. A tooth can become reinfected if bacteria re-enter through a cracked seal, a damaged crown, or a canal not identified during the initial procedure. Signs include returning pain, swelling, or sensitivity. In many cases, endodontic retreatment can resolve the problem and preserve the tooth.
Yes. A tooth treated years ago can become reinfected if the crown fails, a new cavity develops, or a crack lets bacteria back into the root. Regular exams and X-rays help catch changes in treated teeth before symptoms appear.
Most dental insurance plans classify root canal treatment as a major restorative procedure, typically covering 50 to 80 percent of the cost after your deductible. We work with BlueCross BlueShield, Humana, Cigna, Aetna, and Florida Combined Life, and financing is available through CareCredit, Cherry, and our in-house membership plan.
A properly treated and crowned tooth can last a lifetime with routine care. The most important factors are timely placement of a protective crown, twice-yearly cleanings to monitor the treated tooth, and consistent daily oral hygiene.
