Can I Go to the ER for a Dental Emergency?

Yes. You can go to an emergency room for a dental emergency. The ER can control pain, start antibiotics for a spreading infection, and stabilize a jaw fracture or a threat to your airway. For a toothache, a lost filling, or a knocked-out tooth, call an emergency dentist first. They can treat the tooth, which an ER visit rarely does.

When the ER is the right first stop#

Go now, without waiting for a dental office to open, if you have:

• Facial swelling that is spreading, especially near the eye or toward the neck
• Trouble breathing or swallowing
• High fever with dental infection symptoms
• A jaw injury that may be fractured
• Bleeding from the mouth that does not stop with direct pressure

Those signs mean the infection or injury may have moved beyond the tooth. What counts as a dental emergency lists the same red flags. An ignored abscess can track into the face and neck; how to identify an oral abscess covers the warning signs.

The Scottish Dental Clinical Effectiveness Programme groups these as emergency-level problems that should reach a clinician within about 60 minutes.

What the ER can do#

Emergency physicians manage pain and swelling, prescribe antibiotics when infection is spreading, treat facial trauma, and admit you if the infection is life-threatening. Between 2008 and 2010, U.S. hospital ERs recorded about 4 million visits with a dental diagnosis, roughly 1 percent of all ER visits, at a mean charge of about $760 in 2010 dollars (Allareddy et al., 2014).

Most of those visits stay palliative. In an Oregon study of nontraumatic dental ER visits, clinicians prescribed opioids at 56 percent of visits and antibiotics at 56 percent; the visit generated about $402 in hospital costs, and the tooth itself usually went untreated (Sun et al., 2015). Repeat visits are common because the source of the pain stays in the tooth (Davis, Deinard, & Maïga, 2010).

What a dentist still has to do#

Definitive care is pulpotomy, pulpectomy, root canal treatment, incision and drainage, or extraction. The ADA antibiotic guideline, which the American College of Emergency Physicians endorses, tells clinicians to prioritize that dental treatment. Antibiotics help when you have fever or malaise, or when the infection is spreading. They leave the source in the tooth until someone opens it or drains the pus. Current abscess antibiotic guidance walks through the same recommendations.

A dentist is also the person who can perform a root canal, extract the tooth, repair a broken tooth, replace a lost filling or crown, or replant a knocked-out permanent tooth.

If a tooth is knocked out, handle it by the crown, keep it moist in milk or saline, and get to a dentist or endodontist. Replanting within 30 to 60 minutes gives the best chance the tooth will survive (Fouad et al., 2020). An ER may temporarily stabilize it; you still need dental follow-up. What to do if you knock out a tooth covers the first hour.

When to call an emergency dentist instead#

Call a dentist, or an after-hours emergency dental line, for pain, a broken or knocked-out tooth, a lost filling or crown, or a dental abscess without spreading swelling, fever, or airway symptoms. Can I get a same-day dentist appointment? explains how offices triage those calls. The ADA office triage sheet tells staff to schedule you the same day for trauma, fever with swelling, or pain that wakes you at night.

Cost of an ER visit for a tooth#

The ADA reports that ER visits for dental pain often run $400 to $1,500, compared with $90 to $200 at a dental office, and that the United States sees about 2 million such ER visits a year. Because the ER visit rarely finishes the treatment, many people pay for both the hospital bill and a later dental appointment.

Frequently asked follow-ups#

Will the ER give me antibiotics for a tooth infection?#

Often yes, if there is a clear spreading infection or fever. Antibiotics still leave the source in the tooth. You need a dentist for the root canal, drainage, or extraction.

What if it is the middle of the night and I am in severe pain?#

Call your dentist's after-hours line first if you have one. If you have trouble breathing or swallowing, a high fever, or spreading facial swelling, go to the ER without delay.

Is it more expensive to go to the ER for a dental issue?#

Usually yes. Allareddy and colleagues found a mean ER charge of about $760, and you may still need a dental visit afterward.

Key takeaways#

• Go to the ER for spreading facial swelling, trouble breathing or swallowing, high fever with infection, a suspected jaw fracture, or bleeding that will not stop.
• The ER can control pain and start antibiotics; a dentist still has to treat the tooth.
• Call an emergency dentist first for a toothache, a lost filling or crown, or a knocked-out tooth.
• An ER dental visit often costs several hundred dollars and still needs a follow-up dental appointment.
