Call 911 or go to the nearest emergency room now if a dental problem comes with any of these:
- Swelling of the face or neck along with fever, swelling spreading toward the eye, or a swollen jaw or floor of the mouth — a dental infection may be spreading and can become life-threatening.
- Any difficulty breathing or swallowing, drooling because you cannot swallow, or a muffled “hot potato” voice.
- Uncontrolled bleeding from the mouth that does not slow after firm pressure.
- Facial trauma or a possible broken jaw, especially after a fall, crash, or blow to the head.
These are medical emergencies, not routine toothaches. A spreading dental infection can reach the airway or bloodstream, and swelling that closes off breathing or swallowing needs emergency treatment immediately. A knocked-out permanent tooth is also time-critical — see the first-aid steps below and get to a dentist right away.
A cracked tooth at midnight, a knocked-out incisor during a weekend soccer game, or a throbbing abscess that will not wait until Monday — dental emergencies do not follow office hours. According to the American Dental Association, millions of emergency room visits each year in the United States are for dental conditions, often costing an estimated $1,000 to $2,500 per visit for what may be only a prescription and a referral. Understanding emergency dental care — what qualifies, what to do immediately, and where to actually get treated — can save you money, pain, and potentially a tooth. For broader guidance on staying ahead of health issues before they become emergencies, see our preventive health and wellness guide.
The short version: True emergencies — facial or neck swelling with fever, trouble breathing or swallowing, uncontrolled bleeding, or jaw trauma — go to the ER or 911. A knocked-out permanent tooth is an urgent dental problem: keep it moist in milk or saliva, handle it only by the crown, and get to a dentist fast. Most other problems (chipped teeth, lost fillings, manageable toothaches) are urgent but can usually wait a day or two for a dentist or an emergency dental clinic, where care costs a fraction of an ER visit.
What Counts as a Dental Emergency
Not every toothache requires a midnight trip to the ER. True dental emergencies involve situations where delaying treatment risks permanent damage, uncontrolled infection, or severe pain that cannot be managed at home. The ADA describes a dental emergency as any situation requiring immediate treatment to stop ongoing tissue bleeding, relieve severe pain, or address an infection that could become life-threatening.
Life-threatening emergencies (ER or 911): facial or neck swelling with fever, difficulty breathing or swallowing, uncontrolled oral bleeding, a fractured or dislocated jaw, and significant facial trauma. These take priority over any dental office visit.
Dental urgencies (see a dentist quickly, often same day): a knocked-out permanent tooth (act within about an hour), a dental abscess without the red-flag signs above, and a broken tooth with exposed nerve tissue causing extreme pain.
Situations that can usually wait 24 to 48 hours: a cracked or chipped tooth without severe pain, a lost filling or crown, a loose orthodontic wire causing mouth sores, and a moderate toothache that responds to over-the-counter pain relievers.
Immediate First Aid for Common Dental Emergencies
What you do in the first few minutes after a dental emergency can determine whether a tooth is saved or lost. Here is how to handle the most common scenarios before you reach professional care.
Knocked-Out Tooth
Pick the tooth up by the crown (the white chewing surface), never by the root. If it is dirty, rinse it gently with milk or saline for a moment — do not scrub it, use soap, or dry it. Try to place the tooth back into its socket right away and bite down on a clean cloth to hold it in place, because the socket is the best environment for it. If you cannot reinsert it, keep the tooth moist by placing it in a container of milk, or hold it inside your cheek so it stays bathed in saliva; a commercial tooth-preservation kit (such as Save-a-Tooth) is also ideal if available. Do not store it in plain tap water, which can damage the root-surface cells. Time is critical: the American Association of Endodontists advises seeing a dentist or endodontist within about 30 minutes for the best chance of saving the tooth, while noting that a tooth can sometimes still be saved even after an hour or more outside the mouth. Get to a dentist or ER immediately. (Baby teeth are generally not reimplanted, as doing so can harm the developing permanent tooth underneath.)
Severe Toothache
Rinse your mouth with warm salt water (about half a teaspoon of salt in a glass of warm water). Floss gently around the affected tooth to remove any trapped food debris that might be causing pressure. For pain, you can use an over-the-counter pain reliever taken exactly as directed on the package — do not place aspirin directly against the gum, as this can cause a chemical burn to the tissue. Apply a cold compress to the outside of your cheek in short intervals to reduce swelling, and avoid applying heat, which can worsen infection-related swelling. If pain is severe, persistent, or accompanied by any of the red-flag signs above, seek care promptly.
Cracked or Broken Tooth
Rinse with warm water to clean the area, and apply a cold compress to reduce swelling. If the break has left a sharp edge, cover it with dental wax or sugar-free gum to protect your tongue and cheek. Save any tooth fragments in milk or saline — your dentist may be able to use them. Avoid chewing on that side and stick to soft foods until your appointment. A crack with severe pain, bleeding, or an exposed nerve should be seen urgently.
Dental Abscess
An abscess is a pocket of infection at the root of a tooth or in the gum tissue. Signs include a persistent, throbbing toothache, sensitivity to hot and cold, fever, swelling in the face or cheek, and a pimple-like bump on the gum that may drain foul-tasting fluid. Rinsing gently with mild salt water several times a day may ease discomfort, but it does not treat the infection — an abscess needs professional care. Do not attempt to pop or drain the abscess yourself, and do not rely on leftover antibiotics; antibiotics must be prescribed and dosed by a clinician who can also address the source of the infection.
When an abscess becomes an emergency: Call 911 or go to the nearest emergency room if you develop a high fever, difficulty swallowing or breathing, swelling that spreads to your neck or toward your eye, or new confusion. A dental infection can spread to the bloodstream or the airway, both of which are life-threatening. Otherwise, see a dentist as soon as possible — usually the same day — to have the infection properly treated.
Where to Go for Emergency Dental Care
Your options depend on the time of day, the severity of the emergency, and your insurance situation. Here is a practical breakdown of where to seek care.
Your regular dentist should be your first call for a dental urgency. Many dental offices maintain an after-hours emergency line, and some will open on weekends for established patients with true emergencies. If you do not have a regular dentist, call the nearest dental office anyway — many accept emergency walk-ins.
Emergency dental clinics are standalone facilities that specialize in same-day and after-hours dental treatment. They are typically staffed by general dentists equipped to handle extractions, root canals, abscess drainage, and tooth repair. Costs vary by procedure but are generally far less than an ER visit for the same problem. Searching “emergency dentist near me” is a fast way to find facilities in your area.
Urgent care centers with X-ray capabilities can help rule out fractures and prescribe antibiotics or pain medication, but most cannot perform definitive dental treatment. They are a reasonable option when you need pain management and infection control until you can see a dentist the next business day.
Hospital emergency rooms should be reserved for dental emergencies that involve severe bleeding, facial trauma, jaw fractures, difficulty breathing, or signs of spreading infection. ERs can manage pain, administer IV antibiotics and fluids, and treat fractures, but they typically do not have dentists on staff and cannot perform root canals, extractions, or restorative work. Expect the ER to stabilize you and refer you to a dentist for definitive care.
Cost of Emergency Dental Treatment
Dental emergencies can be expensive, and costs vary widely by location, provider, and whether you have insurance. As rough, non-guaranteed estimates without dental insurance, typical costs include an emergency exam and X-rays ($100 to $300), a simple extraction ($150 to $350), a surgical extraction ($200 to $650), a molar root canal ($700 to $1,500), abscess drainage and antibiotics ($150 to $500), and a crown ($800 to $1,800). An ER visit for a dental problem is often estimated at $1,500 to $2,500, and that usually covers only temporary measures — you will still need follow-up dental care. For more on planning around these expenses, see our healthcare costs guide.
With dental insurance, you will typically pay a percentage of the procedure cost after your deductible, and most dental plans cap annual benefits (commonly around $1,000 to $2,000), so a complex emergency can quickly exhaust your yearly limit. If you do not have dental insurance, ask the office about payment plans, sliding-scale fees, or discounts for paying in cash at the time of service. Dental schools also offer lower-cost care performed by supervised dental students — check with schools in your area. Never delay treatment for a true emergency over insurance questions; your health and airway come first.
What to Expect During Emergency Dental Treatment
The specific treatment you receive depends on the nature of the emergency. Understanding what is involved can ease anxiety and help you make informed decisions under pressure.
For a knocked-out tooth, the dentist will attempt reimplantation if the tooth is viable, splinting it to adjacent teeth with a flexible wire for a couple of weeks while the periodontal ligament reattaches. Root canal therapy is often needed soon afterward. Outcomes are best when the tooth was kept moist and reimplanted quickly — the American Association of Endodontists emphasizes that prompt action and proper storage give the tooth its best chance.
For dental abscesses, treatment involves draining the infection (either through the tooth via a root canal or through an incision in the gum) and, when appropriate, a course of antibiotics prescribed and dosed by your dentist or physician — including an alternative antibiotic for people allergic to penicillin. The dentist may also recommend pain relief and an antiseptic rinse. A follow-up appointment is typically scheduled within a week or two to assess healing and determine whether the tooth can be saved or needs extraction.
For cracked teeth, treatment ranges from bonding or a dental crown (for minor cracks) to root canal therapy (for cracks extending into the pulp) to extraction (for cracks extending below the gum line). Your dentist will use X-rays and sometimes a transillumination test (shining a bright light through the tooth) to assess the extent of the crack and choose the most conservative effective treatment.
Preventing Dental Emergencies
Many dental emergencies are preventable. Regular dental checkups (generally every six months, or as your dentist advises) catch problems like cavities and weakened teeth before they crack or become infected. Wear a custom or well-fitted mouthguard during contact sports; the ADA notes that mouthguards prevent large numbers of oral injuries each year. Avoid using your teeth as tools — opening bottles, tearing packages, or cracking nuts — which is a leading cause of tooth fractures.
If you grind your teeth at night (bruxism), talk to your dentist about a nightguard, since chronic grinding weakens enamel and increases fracture risk over time. Maintain good oral hygiene — brushing twice daily, flossing once daily, and limiting sugary snacks and acidic beverages — to prevent the decay and gum disease that underlie many dental emergencies. Addressing dental and healthcare costs proactively through preventive care is almost always cheaper than emergency treatment.
Frequently Asked Questions
Should I go to the ER for a toothache?
In most cases, no. A hospital ER can usually only prescribe pain medication and antibiotics — it cannot perform dental procedures — and you will typically pay much more for temporary relief that a dentist or emergency dental clinic can provide at a fraction of the cost. The important exception is if your toothache comes with high fever, facial or neck swelling, difficulty breathing, or difficulty swallowing. Those signs mean the ER, right away.
Can a knocked-out tooth be saved?
Often yes, if you act quickly. A permanent tooth has the best chance when it is put back in its socket or kept moist and reimplanted within about an hour. Handle it by the crown only, keep it in milk or your own saliva (not tap water), and get to a dentist immediately. Baby teeth should not be reimplanted, as doing so can damage the developing permanent tooth underneath.
How do I know if my tooth is cracked?
Common signs include sharp pain when biting or chewing (especially on release), sensitivity to hot, cold, or sweet foods and drinks, intermittent pain that comes and goes, and swelling of the gum around the affected tooth. Some cracks are invisible to the naked eye and require dental X-rays or a special dye or light test to detect.
Does dental insurance cover emergency visits?
Most dental insurance plans cover emergency exams and X-rays. Coverage for treatment such as extractions and root canals depends on your plan’s benefits and whether you have met your deductible. Check with your insurer before the appointment if you can, but do not delay emergency treatment over insurance questions — your health comes first.
Can I just take leftover antibiotics for a dental infection?
No. Taking leftover or someone else’s antibiotics can be the wrong drug or dose, can mask a worsening infection, and contributes to antibiotic resistance. A dental infection also needs the source addressed (drainage, a root canal, or extraction), which antibiotics alone do not accomplish. See a clinician who can prescribe and dose treatment appropriately.
What to Do Next
If you are dealing with a true emergency — facial or neck swelling with fever, trouble breathing or swallowing, uncontrolled bleeding, or jaw trauma — call 911 or go to the ER now. For a dental urgency, call your dentist’s emergency line first; if they cannot see you, search for an emergency dental clinic in your area. For a knocked-out permanent tooth, keep it moist in milk or saliva and get to a dentist within the hour. For non-urgent issues, schedule an appointment for the next business day and use the first-aid steps above to manage pain in the meantime. Once this emergency is behind you, make a plan to prevent the next one — regular checkups, a mouthguard for sports, and consistent daily hygiene go a long way toward keeping your teeth intact and out of the emergency chair.
