The short version: if it keeps you from sleeping, eating or working, it counts.

A dental emergency is any sudden dental problem involving uncontrolled pain, swelling, bleeding that will not stop, or a tooth that has been knocked out, broken or loosened by an injury. Those need to be seen within a day or so, not at your next checkup. A chipped tooth that does not hurt, a lost filling with no pain, or a dull ache that comes and goes are urgent-ish rather than emergencies — book soon, but you are not in danger.
If any of these apply, go to the nearest emergency room or call 911. That is a hospital problem, not a dental one.
If it is keeping you awake or painkillers are no longer touching it, yes — that usually means the nerve is involved or there is infection, and both get worse rather than better. An ache that flares with cold and settles within seconds is not urgent, but it is worth booking.
With swelling, no. Swelling is infection and it spreads along tissue planes in the face and neck. With a chip that does not hurt, waiting is fine. You do not have to wait for Monday, though: we are open Saturdays and Sundays too, 8:00am to 5:00pm, and keep time aside every day for urgent cases. Call (559) 616-7629 any time, day or night, to book.
The pain sometimes does. The cause almost never does. When a nerve dies the pain can stop completely for days or weeks, and people take that as recovery — then it comes back as an abscess. If pain disappears suddenly after being severe, that is a reason to be seen, not a reason to relax.
