Should you go to an emergency room or call a dentist?

Published October 20, 2026

In short

Go to the emergency department (or call 911) for breathing or swallowing difficulty, rapidly spreading facial or neck swelling, fever with facial swelling, uncontrolled bleeding, a suspected broken jaw, or head injury with loss of consciousness. For almost everything else, a toothache, a broken or chipped tooth, a lost filling or crown, a knocked-out tooth, a small localized gum swelling, a dentist is the right call, because emergency departments generally relieve pain and treat infection with medication but do not provide definitive dental treatment such as fillings, root canal treatment or extractions.

Something stuck between teethTry floss; dentist if it stays

The American Dental Association's emergency guidance covers these situations (ADA).

If any of these apply, this is not a dental-office problem first: trouble breathing or swallowing, rapidly spreading swelling of the face or neck, fever with facial swelling, bleeding that will not stop, or a serious injury to the head or jaw. Call 911 or go to the nearest emergency department. Do not use the appointment request form for these.

What an emergency department can do

Assess airway and systemic infection, control bleeding, manage trauma, prescribe medication, and image a jaw. It usually cannot fill, root-treat, re-cement or extract.

What a dentist can do

Diagnose the tooth, drain an abscess, start a root canal, extract, repair, re-cement, and plan the definitive repair.

When the office is closed

Follow the instructions on the office's voicemail or website; this page does not promise any availability. For the emergency signs above, do not wait for an office to open.

Next step: Request a consultation or call (805) 565-5111. A request is not a confirmed appointment; the office confirms times during its listed hours (Monday to Thursday, 8 am to 5 pm, plus select Fridays).
