Tooth Abscess Treatment in Johnson City, TN

Medically reviewed by Dr. Riley Sturgill, DMD, MSD · Last reviewed August 2026

A tooth abscess takes over everything. You are not sleeping well. Chewing on that side is out of the question. Somewhere between the throbbing and the swelling, a quieter question showed up, the one you probably typed into your phone before you found this page: how bad is this, really?

You deserve a straight answer, so here it is in two parts. Most tooth abscesses can be treated successfully in a dental office, and they are very treatable. A small number produce symptoms that mean the infection needs emergency medical attention, and you need to be able to tell the difference tonight rather than next week.

First, Rule Out the Emergency

Mayo Clinic advises emergency evaluation for difficulty breathing or swallowing, because those symptoms can indicate that infection has spread into deeper tissue. Do not talk yourself into believing you can still swallow well enough to make it until morning. Infections in this part of the body can move faster than they feel like they are moving.

If none of those signs describes you, and what you have is a sore tooth, a tender bite, a gum bump, or swelling confined to one spot with no fever, you still need prompt evaluation rather than a wait-and-see week. Call as soon as we are open and mention any swelling when you do, so the team can judge how quickly you should be seen. We are open Monday through Thursday. If it is the weekend and anything on the list above appears, that is the emergency room and not a voicemail.

What an Abscess Actually Is

A tooth abscess, also called a dental abscess, starts inside the tooth. Inside every tooth is a soft core called the pulp, a small bundle of nerve and blood vessel tissue running from the crown down through the roots. Bacteria reach that core through a deep cavity, a cracked tooth, an old failing filling, or an injury from years ago you may have forgotten about.

Once bacteria get in, the pulp becomes inflamed and eventually dies. The infection then travels down the canals and exits through the tiny opening at the root tip into the bone. That pocket of infection at the root tip is a periapical abscess. The American Association of Endodontists describes the same sequence, where pulp dies, becomes inflamed, goes untreated, and infection settles in or around the root.

Sometimes the body carves a small drainage channel through the gum to relieve the pressure. That is the little pimple-like bump some patients notice, and it explains the salty or foul taste that shows up and then disappears. It feels like the problem resolved itself. That is not what happened. The pressure dropped, and nothing else changed.

Tooth Abscess Symptoms People Usually Notice

Symptoms vary more than most people expect, and one abscessed tooth will not necessarily produce all of them.

Why It Will Not Clear Up on Its Own

Your immune system reaches infected tissue through the bloodstream. That is how you have recovered from most infections in your life without ever thinking about the mechanism.

The pulp inside an abscessed tooth is dead tissue whose blood supply is gone. Your immune system can still fight at the border, out in the bone, which is why swelling sometimes rises and falls for months. What it cannot do is clear the bacteria living inside the root canal system, because circulation no longer reaches that space.

That lost blood supply is the whole reason an abscess behaves differently from other infections you have had.

Why Antibiotics Alone Will Not Fix It

This one surprises almost everyone, so here is what is actually happening.

Antibiotics travel the same road your immune cells do. They work well out in the swollen gum and face, which is why a course of antibiotics can reduce swelling and make you feel considerably better, as though the problem has been solved. Inside the tooth, where the source of the infection sits, circulation no longer reaches, so antibiotics cannot reliably get to the bacteria living in the canal system.

This is not a fringe position. The American Dental Association guideline on antibiotics for dental pain and swelling, endorsed by the American College of Emergency Physicians, recommends against antibiotics for most pulpal and periapical conditions in healthy adults and directs dentists to prioritize the dental treatment itself, meaning root canal treatment or drainage. Antibiotics become appropriate once infection turns systemic and produces fever or malaise.

So the swelling tends to come back. Maybe in three weeks, maybe in eight months, sometimes at a worse moment than the first time.

None of this means your dentist was wrong to prescribe them. Antibiotics have an important role when infection is spreading, when systemic symptoms show up, or when your health situation calls for them. They are a fire break rather than a cure. The fire is still inside the tooth.

If the Pain Stopped, Read This Twice

A tooth that hurt viciously for four days and then went quiet has not necessarily healed. Often the pulp has finished dying, and because pain is generated by living nerve tissue, the signal disappears along with it. Sometimes an abscess has drained and the pressure simply dropped.

Either way, less pain is not evidence that the infection is gone. The bacteria are still there. Whatever is happening in the bone continues on its own schedule, and what changed is your ability to feel it.

Patients tell us all the time that they waited because it stopped hurting, and there is nothing foolish about that. Every instinct you have says pain gone equals problem gone. With an abscessed tooth, that instinct runs backwards.

The Abscess You Never Felt

Plenty of people land on this page for the opposite reason. Nothing hurts. You went in for a cleaning, your dentist took a routine X-ray, pointed at a dark shadow near the root tip, and referred you here. Everything feels normal, and now you are wondering whether any of this is necessary.

That dark area usually represents bone loss and inflammation around the root tip, the kind chronic infection produces. An image on its own does not settle the question, which is why the tooth gets pulp tested and examined alongside the scan rather than diagnosed off a shadow. What the absence of pain tells you is that the nerve most likely died quietly, not that the problem is small.

Being caught this way is the good version. Your dentist found it before it became the 2am kind, and you get to handle it on a calendar instead of in a crisis.

Is This a Root Canal?

For most abscessed teeth, yes. Root canal treatment is how the source gets removed. The infected pulp comes out, the canal system gets cleaned and disinfected down to the root tip, and the space is sealed so bacteria have nowhere to recolonize. Once the source is gone, the abscess in the bone usually resolves and the bone fills back in over the following months.

If you do not yet know which tooth is causing this, that is what an evaluation is for. Finding out what is wrong is not the same as committing to a procedure.

When there is active swelling, the abscess may be drained first to relieve pressure. Relief from that is usually immediate, though drainage does not treat the tooth, so it works as a first step rather than the fix.

Some teeth need a different route. A tooth with a previous root canal that later abscessed usually needs root canal retreatment. Persistent infection at the root tip despite sound earlier treatment may call for an apicoectomy, a small procedure that removes the very tip of the root and seals it from the end.

And some teeth cannot be saved. A root fractured down its length, or a tooth with too little structure left to rebuild, is better removed than repeatedly rescued. We would rather tell you that at the consultation than recommend treatment unlikely to give the tooth a durable result. Deciding that honestly is a large part of what a specialist is for.

Whether the tooth needs a crown afterward, and whether we place it here or coordinate with your dentist, depends on the tooth. Many patients finish the whole thing in one place without a separate trip back. We will tell you which situation you are in before we start rather than leaving you to find out later.

Finding the Right Tooth Before Touching Anything

Abscess pain lies about its location. It refers along the jaw, up into the ear, across to the opposite arch, and into the sinus. Patients routinely point at the wrong tooth, and they point confidently.

Every patient here gets CBCT 3D imaging and a dental operating microscope on every case, not as an upgrade or an add-on for complicated ones. A standard dental X-ray flattens a three-dimensional tooth into a two-dimensional picture, which hides infection behind roots and hides extra canals entirely. The 3D scan shows the size and position of the lesion and reveals canal anatomy that would otherwise get missed. Under high magnification and strong light, the microscope shows those canal openings while the work is happening.

Missed anatomy is one of the more common reasons a root canal fails years later. Seeing it is how you avoid it.

What the Next Few Weeks Actually Look Like

Here is the part nobody describes, and it is the part you are really asking about.

• Treatment day

  You get numb, and getting numb through infected tissue takes extra technique, which is a normal part of the job here. Most patients report the appointment feels similar to having a filling done, just longer. Many are surprised by how boring it is.

• That night

  Most patients notice that the pressure and the specific throb that had them counting hours until the next dose of ibuprofen are substantially better. Some tenderness around the tooth is normal for the first few days, since the tissues around the root are still irritated, and that soreness generally responds well to over-the-counter medication.

• The first couple of weeks

  Soreness settles and normal routines come back. Go easy on that tooth while it heals, since the AAE advises against biting down heavily on a treated tooth until it has been fully restored and you have been cleared. Whether that restoration happens here or with your dentist depends on the tooth, and you will know which before you leave.

• Months later

  Healing in the bone gets checked at a follow-up, and the dark area on the image is typically smaller or gone. The tooth is yours, still in your jaw, doing its job. No implant and no bridge.

That is the outcome we are aiming at, and for the large majority of abscessed teeth it is a realistic one.

If You Are Dreading the Chair

Dental anxiety is not a character flaw, and an abscess makes for a rough introduction to a specialist's office. So the practical side is handled here rather than left to willpower.

Coffee, sparkling water, and ear plugs are out front. Patients mention the comfort menu in reviews without being prompted, which usually signals that something is actually being used rather than listed on a website.

Cost, and the Out-of-Network Question

Sturgill Endodontics is out of network with all insurance carriers. That deserves explaining, because out of network is not the same as not covered.

Most dental plans include out-of-network benefits. We do not bill your insurer directly. What we do is help you complete all of the paperwork so you can file with your plan and be reimbursed under your out-of-network benefits, and we will review your specific plan and give you an estimated out-of-pocket figure before treatment starts.

One number belongs next to the fee. Treating the tooth is almost always less expensive than removing it and replacing it. An extraction leads to an implant or a bridge, and that total runs well past what it costs to save what you already have.

Who You Would Be Seeing

Two endodontists practice here, and endodontics is all either of them does. Neither one does cleanings or fillings. Root canal systems and infected teeth, all day.

Dr. Riley Sturgill founded the practice. She holds a DMD along with an MSD and a Certificate in Endodontics from Virginia Commonwealth University, and she teaches in VCU's endodontic residency program, which means she spends part of her professional life explaining to residents exactly why a canal system behaves the way it does.

Dr. Colton Fischer holds a DDS along with an MSD and a Certificate in Endodontics, also from VCU, plus additional microsurgery training at the University of Pennsylvania School of Dental Medicine. He is a Board Certified Diplomate of the American Board of Endodontics, a credential that requires passing written and oral examinations before a board of peers and that a minority of endodontists hold.

Patients come from Kingsport, Bristol, Elizabethton, Abingdon, and the rest of the Tri-Cities, most of them referred by their own dentist. If yours sent you here, that is the system working the way it is supposed to. General dentists handle an enormous range of care, and they refer abscessed teeth to endodontists for the same reason a physician refers a complicated case to a specialist. It is a sign your dentist is paying attention.
