Losing a filling or crown is unsettling in the moment but rarely a true emergency — the priority is protecting the exposed tooth from further damage or discomfort until we can see you, which is usually within a day or two rather than immediately.
Why it happens
Fillings and crowns can loosen over years of chewing pressure, temperature changes, or decay developing underneath them at the margin. Sticky or hard foods are common triggers for dislodging one that was already becoming loose.
What to do right away
- Save the crown or filling piece if you can find it — bring it to your appointment, since it can sometimes be re-cemented
- Gently clean the exposed tooth surface by rinsing with warm water
- If the tooth feels sharp or is irritating your tongue or cheek, cover it temporarily with dental wax, sugar-free gum, or an over-the-counter temporary filling material from a pharmacy
- Avoid chewing on that side of your mouth until it's repaired
Managing sensitivity in the meantime
The exposed tooth surface is often sensitive to hot, cold, and air, since the filling or crown was protecting it. Avoiding extreme temperatures and sticking to the opposite side of your mouth for chewing usually keeps things comfortable until your repair visit.
When it becomes more urgent
If losing the filling or crown reveals significant pain, a visibly broken tooth underneath, or signs of infection like swelling, that moves it from a routine repair to something worth same-day attention — call us and describe what you're seeing so we can advise appropriately.
What the repair visit typically involves
If the original crown or filling is intact and the tooth underneath looks healthy, it can sometimes simply be re-cemented. If decay is found underneath, or the piece is damaged, a new filling or crown is usually needed — either way, it's typically a straightforward, single-visit fix.
Most repairs are simple, same-visit fixes — see our restorative care page for what to expect.
