Losing a filling or crown is rarely a true dental emergency, but it is not something to sit on either. Unless you have severe pain, swelling, or bleeding, you do not need to rush to an emergency room. What you do need is a dental visit within a few days, because the tooth underneath is now exposed, softer than enamel, and more vulnerable with every day that passes.
Here in Oakland and the surrounding communities, this is one of the most common urgent calls we expect to receive, and the advice fits in one sentence: protect the tooth, save the crown, and get seen soon. Here is the fuller version.
Emergency or Urgent? How to Tell the Difference
A lost filling or crown by itself is urgent, not an emergency. It becomes an emergency when other symptoms join it:
- Severe or throbbing pain that over-the-counter relief does not touch.
- Swelling in the gum, face, or jaw, which can signal infection.
- Bleeding that does not stop with gentle pressure.
- A cracked or broken tooth underneath, not just a missing restoration.
With any of those, call the same day, and our guide to what counts as a dental emergency walks through the rest of the list. Without them, a few days of careful eating while you wait for an appointment is perfectly safe, and if this happened at night, you can wait until morning.
What to Do in the First Hour
- Find and keep the crown. A crown that is intact can often be cleaned and recemented, which is the cheapest possible outcome. Put it somewhere safe, not loose in a pocket.
- Rinse gently with warm water to clear the area.
- Check for sensitivity. Exposed dentin often reacts to cold, sweets, or air. This is normal and not by itself alarming.
- Cover sharp edges if needed. If a rough edge is bothering your tongue or cheek, a small piece of orthodontic wax or sugar-free gum over the area works as a short-term buffer.
- Call the dentist and describe what happened, including whether anything hurts.
What Not to Do
Do not glue a crown back with anything from the garage or the junk drawer. Household adhesives are unsafe in the mouth and can permanently ruin both the crown and the tooth, closing off the recementation option entirely. If you want a stopgap, pharmacies sell temporary dental cement made for exactly this. Even then, treat it as a bridge to your appointment, not a repair. A crown seated at a slightly wrong angle can throw off your bite quickly.
Also resist the urge to keep chewing on that side, test the tooth with your tongue constantly, or wait to see if it sorts itself out. It will not.
Why the Tooth Cannot Wait Weeks
Fillings and crowns exist because part of the tooth was already lost to decay or damage. Remove the restoration and you re-expose that vulnerable core. Dentin decays much faster than enamel, the thin walls around a lost filling chip easily, and neighboring teeth begin drifting into any gap sooner than most people expect. A lost crown handled this week is often a simple recementation. The same crown handled in three months may find new decay underneath, and the conversation changes.
If you are curious how long restorations are supposed to hold up in the first place, we have written guides on how long crowns last and how long fillings last, including the warning signs that one is nearing the end of its life.
What Happens at Your Appointment
The visit is usually simple. We examine the tooth and the restoration, take an x-ray if needed, and check for decay underneath. From there, the paths are: recement the original crown if it fits and the tooth is sound, place a new filling or crown if it does not, or, if decay has reached deeper than expected, talk through the options honestly before doing anything. Most lost-restoration visits end with the tooth protected the same day.
