Emergency Dentist in Knoxville, TN: ER vs. Dentist & Where to Go
A tooth emergency splits into two very different problems: the rare one that can threaten your airway and belongs in an emergency room, and the much more common one that belongs in a dental chair. This page helps you make that call in under a minute, handle the first hour well, and find verified care in Knoxville - including walk-in, sliding-scale, and free options.
THE SHORT ANSWER
Dental emergency in Knoxville? Go to the ER or call 911 for swelling that affects breathing or swallowing, major facial trauma, or uncontrolled bleeding - everything else belongs with a dentist. A knocked-out tooth has its best chance if reimplanted within 30-60 minutes, kept moist in milk. Below: the ER-vs-dentist call, first-hour steps, costs, and where to go.
A note on prices: every dollar figure on this page is a 2026 national estimate, not a Knoxville quote. We could not verify any Tennessee-specific emergency dental prices, so we publish national ranges and label them as estimates rather than guess at local numbers. Always ask what a visit will cost before treatment starts.

ER or emergency dentist? Decide in 30 seconds
Most dental emergencies feel bigger than they are - pain is a poor guide to danger. The real dividing line is your airway and your blood loss, not how much something hurts. An abscess (a pocket of infection at the root of a tooth or in the gum) can be miserable and still be a dentist problem. Swelling that starts closing your throat is a hospital problem, full stop.
Here is the honest tradeoff people miss: an emergency room is excellent at keeping you safe and poor at fixing teeth. ER doctors stabilize you, manage pain, and treat a spreading infection, but they do not fill, crown, or pull teeth - they are not set up for dental procedures. If your problem is the tooth itself, the ER visit usually ends with a referral to a dentist anyway. Going straight to a dentist when it is safe to do so saves you a second bill and a second wait.
| What is happening | Go to | Why |
|---|---|---|
| You have swelling that affects breathing or swallowing | ER / 911 | This is an airway emergency. Swelling in the floor of the mouth or throat can close your airway; hospitals can secure it and treat the infection. |
| Facial trauma with other injuries - a fall, crash, or blow that may have broken bones or caused a head injury | ER / 911 | Broken jaws, head injuries, and deep cuts need medical care first. The teeth can be assessed once you are stable. |
| Bleeding that will not stop with 15-20 minutes of firm pressure on gauze | ER / 911 | Uncontrolled bleeding is a medical emergency, especially if you take blood thinners. |
| Severe tooth pain | Emergency dentist | Pain points to a dying nerve, deep decay, or infection inside the tooth. A dentist can diagnose it with X-rays and treat the cause. |
| A knocked-out permanent tooth | Emergency dentist | Time-critical but dental: the tooth has its best chance if it is back in the socket within 30-60 minutes. See the playbook below. |
| A broken or cracked tooth | Emergency dentist | A dentist can smooth, bond, crown, or - if the crack reaches the root - remove the tooth before it gets infected. |
| A lost filling or crown | Emergency dentist | Uncomfortable and worth fixing promptly, but rarely dangerous. Keep the crown if you still have it; a dentist may be able to re-cement it. |
| An abscess - a painful, swollen bump on the gum or a tooth that aches and throbs - without any trouble breathing | Emergency dentist | The infection is real and should not wait days, but if your breathing and swallowing are fine, a dentist is the right and faster fix. |
The one rule that overrides everything else
If swelling is making it hard to breathe or swallow, if swelling is spreading under your tongue, or if you have a fever with swelling that is getting worse fast, stop reading and call 911 or go to the ER. Dental infections that reach the airway are the one dental problem that can turn life-threatening in hours.
Call your dentist first
If you already have a dentist, call their number even after hours - most practices have on-call or answering-service coverage for existing patients in pain.
No dentist of your own?
Use the Knoxville options in the "Where to go" section below - including a daytime walk-in clinic and free and sliding-scale care for people without insurance.
Not sure which it is?
Ask one question: "Is my breathing or swallowing affected?" If the answer is yes or even maybe, choose the ER. If clearly no, choose the dentist.
Knocked-out tooth: the first-hour playbook
A knocked-out permanent tooth is the one dental emergency where minutes genuinely change the outcome. The tooth's root is coated in living cells that die quickly when they dry out, and a dentist's chances of saving the tooth are best when it is reimplanted - put back into its socket - within 30-60 minutes. The steps below are general clinical guidance consistent with ADA consumer advice; they are first aid, not a substitute for getting to a dentist.
- Pick the tooth up by the crown. The crown is the white chewing part you normally see. Never touch the root - the pointed end that sat in your jaw. Handling the root damages the cells the tooth needs to reattach.
- Rinse gently if it is dirty. A brief rinse with water is fine. Do not scrub it, do not use soap, and do not wrap it in tissue or cloth, which dries it out.
- Try to put it back in the socket. Face the tooth the right way round, ease it back into place, and bite down gently on gauze or a clean cloth to hold it there.
- If it will not go back, keep it moist. The best readily available option is a small container of milk. If that is not possible and it is safe to do so, the tooth can ride inside the cheek - but never do this for a young child or anyone who might swallow it.
- Get to a dentist within 30-60 minutes. Call ahead and say "knocked-out tooth" - offices treat that phrase as drop-everything urgent. If no dentist is reachable, go to the ER, which can at least protect the tooth and manage any other injuries.
Never reinsert a baby tooth
Everything above applies to permanent (adult) teeth only. Do NOT try to reinsert a knocked-out baby tooth: pushing it back in can damage the permanent tooth developing underneath it. Instead, control any bleeding with gentle pressure, comfort the child, and call a dentist for advice.
One more honest note: even perfect first aid does not guarantee the tooth survives. Reimplanted teeth often need a root canal later (treatment that removes the tooth's inner nerve and seals it), and some fail months or years down the road. But the first hour is when you have the most control over the outcome, and doing the steps above costs nothing.
What emergency care costs
Emergency dental pricing has two layers: what you pay to be seen and stabilized, and what the actual fix costs. Many people are surprised - and sometimes suspicious - when an emergency visit ends with a temporary fix and a follow-up appointment instead of the finished treatment. That is usually how emergency care is supposed to work, not an upsell. The ranges below are 2026 national estimates for patients without insurance; they are the best honest anchors available, because no verified Tennessee-specific emergency prices exist.
| Care | 2026 national estimate | Notes |
|---|---|---|
| Emergency exam + X-rays | $50-350 | The entry cost of almost every emergency visit - a focused exam and images of the problem tooth. |
| Simple extraction | $75-500 | Removing a tooth that cannot be saved. Surgical extractions cost more and are quoted separately. |
| Filling | $90-450 | For a broken tooth or lost filling where the remaining tooth is healthy enough to rebuild directly. |
| Root canal | $500-1,800 | Price climbs from front teeth to molars, which have more canals. A crown afterward is a separate cost. |
After-hours fees may apply on top of these ranges when a practice opens specially for you at night or on a weekend. Ask about that fee when you call - a straightforward office will quote the visit cost on the phone. If an office will not name any price until you are in the chair, that is worth weighing.
Which tooth it is
Molars are the most expensive teeth to treat - more roots, more canals, harder to reach. Front teeth sit at the low end of most ranges.
Stabilize now, fix later
The emergency visit usually buys the diagnosis and gets you out of pain. The root canal, extraction, or crown is often a separate, scheduled charge.
When you go
Nights, weekends, and holidays can add an after-hours fee. A problem seen during regular hours at a teaching or safety-net clinic usually costs least.
What an emergency visit actually does
Expect exam and X-rays first, then stabilization: a clear diagnosis, real pain relief, a prescription if there is infection, and a temporary fix to protect the tooth. The definitive treatment - the root canal, extraction, or crown that finishes the job - often comes at a scheduled follow-up once swelling and pain are controlled. That sequence is normal clinical practice, not a sales tactic.
Where to go in Knoxville
Knoxville has something many cities do not: a dental school clinic, a walk-in urgent care clinic, and a small network of safety-net clinics that treat people without insurance. The five options below are institutions - a university, a health department, and established nonprofits - not private practices, and each listing is drawn from the source cited in the Sources section. Call first before you go: hours change, walk-in slots fill early, and some of these clinics see urgent cases by appointment only.
| Clinic | Address | Phone | Services & who it is for |
|---|---|---|---|
| LMU College of Dental Medicine - student dental clinic | 1705 St. Mary St, Knoxville 37917 | 865-370-2128 | Comprehensive dental care by pre-doctoral students under licensed faculty dentists, at reduced cost. New patients welcome; screening + comprehensive exam; appointments can run up to 4 hours. |
| LMU Community Care Clinic (walk-in urgent dental) | 1718 St. Mary's St, Knoxville 37917 | 865-370-2128 | Daytime walk-in urgent dental care, Mon-Thu 8-10am and 12:30-2pm, first-come first-served. A diagnostic fee applies; treatment is not guaranteed at the visit. |
| InterFaith Health Center | 315 Gill Ave, Knoxville 37917 | 865-546-7330 | Medical + dental for the working uninsured (at/below 250% of federal poverty level), sliding scale. Must have no medical insurance and be ineligible for TennCare. |
| Volunteer Ministry Center - dental clinic | 511 N. Broadway, Knoxville | 865-934-1746 | Fillings, extractions, cleanings (by appointment), dentures - free. For uninsured Knox County residents 18+ at extremely low income or experiencing homelessness. |
| Knox County Health Department - dental clinic | 140 Dameron Ave, Knoxville 37917 | 865-215-5110 | Basic dental care for children; emergency dental services for eligible adults in Knox County. |
Read the fine print before you rely on a listing
Two of these options have real limits worth knowing up front. The LMU Community Care Clinic charges a diagnostic fee and treatment is not guaranteed at the visit - the walk-in gets you evaluated and pointed at the right fix, not necessarily the finished fix. And the LMU student clinic trades money for time: reduced cost, but appointments can run up to 4 hours because students work under faculty supervision. For an emergency, that trade is often worth it; just plan for it.
If you have TennCare
TennCare adult dental coverage
Since January 1, 2023, Tennessee's Medicaid program covers dental care for adults - not just kids. Covered categories include exams, X-rays, cleanings, fluoride, fillings, endodontics (root canals), scaling and root planing, crowns, partial and complete dentures, extractions, and palliative care - at no cost for medically necessary covered services. The dental benefits manager is Renaissance: 866-864-2526 (managing benefits since November 1, 2025).
The word that matters in an emergency is palliative care - treatment that relieves pain and controls infection even before the underlying problem is fully fixed. Palliative emergency care is a covered category, so if you are enrolled in TennCare and in pain, call Renaissance at 866-864-2526 to find a participating dentist rather than assuming you have to pay cash or sit it out.
Before it happens: the 5-minute prep
Dental emergencies are miserable partly because everything has to be figured out while you are in pain. Five minutes of prep on a calm day removes most of that scramble. None of this costs anything.
- Save your dentist's after-hours number. Store it in your phone now, not in a paperwork pile. The ADA advises asking your dentist about emergency coverage before you need it - who takes the call at night, and where they send you if they cannot see you.
- Know what your coverage actually is. If you have TennCare, the dental benefits manager is Renaissance: 866-864-2526. If you have a typical employer PPO plan, expect an annual maximum of roughly $1,000-2,000 per person - the most the plan will pay in a year - and waiting periods of 6-12 months on major work like crowns are common. Knowing your maximum before an emergency keeps a big bill from being a surprise on top of the pain.
- Bookmark the walk-in option. Save the LMU Community Care Clinic's number (865-370-2128) and hours - Mon-Thu 8-10am and 12:30-2pm walk-ins - so a weekday emergency does not start with a search engine.
- Know the milk rule. Tell the people you live with: a knocked-out permanent tooth goes in milk, never wrapped in a napkin, and the clock is 30-60 minutes. Emergencies rarely happen to people who are in a position to read a webpage calmly.
- Keep the ER line clear in your head. Breathing or swallowing trouble from swelling, major facial trauma, bleeding that will not stop: ER or 911, no deliberation. Everything else: dentist.

Frequently asked questions
General clinical guidance: Go to the ER or call 911 for swelling that affects breathing or swallowing, facial trauma with other injuries, or uncontrolled bleeding. See an emergency dentist for severe tooth pain, a knocked-out or broken tooth, a lost filling or crown, or an abscess without breathing trouble. The ER can't do dental work - it stabilizes and refers.
General clinical guidance: Hold the tooth by the crown, never the root. Rinse it gently with water if it is dirty - no scrubbing. Try to reinsert it into the socket; if that is not possible, keep it moist in milk. Get to a dentist within 30-60 minutes.
General clinical guidance: Swelling around one tooth or one side of the jaw usually means an abscess - see a dentist promptly. If it is hard to breathe or swallow, there is swelling under the tongue, or fever with rapidly worsening swelling, go to the ER or call 911 - that is an airway emergency.
Exam and X-rays come first, then stabilization: a diagnosis, pain relief, a prescription if there is infection, a temporary fix, and a scheduled appointment for the definitive treatment. Getting you out of pain safely is the job; the finished fix often comes later.
Using 2026 national estimates: exam and X-rays run $50-350, a simple extraction $75-500, a filling $90-450, and a root canal $500-1,800. An after-hours fee may apply on top. Ask what the visit itself costs before you sit down.
Call your dentist's number first - most practices have after-hours or on-call coverage, and the ADA advises asking about emergency coverage before you need it. If you have no dentist of your own, use the walk-in and urgent options listed on this page. For breathing or swallowing trouble or major trauma, skip the phone tree and go to the ER.
General clinical guidance: Generally no. Emergency rooms are not set up for dental procedures. They evaluate you, manage pain, treat spreading infection, and refer you to a dentist or oral surgeon.
Start with the sliding-scale and free clinics listed on this page. If you have TennCare, adult dental coverage includes palliative emergency care - care that relieves pain and infection without yet fixing the underlying problem - through Renaissance at 866-864-2526. Do not sit at home with a spreading infection: early treatment is cheaper than late treatment in every scenario.
