Dental emergency guide
Lost a crown or filling? Start here.
A crown or filling coming loose can leave a tooth sharp, sensitive, or vulnerable to further damage. These calm first steps can help you protect the tooth until it is checked.
Quick answer
If a crown or filling comes out, save the piece if you have it, avoid chewing on that side, keep the area clean, and call a dentist. Do not use super glue or household adhesives. If you have swelling, severe pain, fever, drainage, or trouble biting, call promptly because the tooth may need urgent evaluation.
A crown or filling coming loose can feel alarming, especially if the tooth suddenly feels sharp, sensitive, or different when you bite. The good news is that a lost crown or filling does not always mean the tooth is ruined. It does mean the tooth should be checked so you can understand what happened and protect it from further damage.
If you are in Lake Stevens, Granite Falls, Marysville, Snohomish, or a nearby community and a crown or filling has come out, here is what to do next.
If you lost a crown or filling, call Lake Stevens Dental at 425-334-1934 for guidance and to schedule an exam.
First steps if a crown or filling comes out
Place the crown or broken piece in a small bag or container and bring it to your appointment.
A tooth without its crown or filling may be weaker, sensitive, or easier to crack.
Warm water can help clear food debris. Brush carefully, but do not scrub aggressively if the tooth is tender.
Pay attention to sharp edges, bite pain, swelling, bad taste, or a pimple-like bump on the gums.
Pharmacy dental cement may help in some situations, but it is not right for every case. If the tooth is painful, broken, swollen, or the bite feels wrong, ask for guidance first.
What not to do at home
A loose crown or missing filling can be frustrating, but some home fixes can make the situation worse.
Do not use:
- Super glue, nail glue, or household adhesives
- Chewing gum as a long-term patch
- Random online dental repair hacks
- Hard foods to test the tooth
Household glues are not made for the mouth and can irritate tissues, trap bacteria, change how the crown fits, or make dental treatment harder. If the crown no longer seats correctly, forcing it back on can also damage the tooth or affect your bite.
When a lost crown or filling is urgent
A lost crown or filling should be checked, but some signs deserve faster attention.
Moderate to severe tooth pain or pain when biting should be evaluated.
Swelling, pus, fever, or a bad taste may point to infection.
A sharp tooth edge that cuts your tongue or cheek may need prompt smoothing or repair.
If the crown came off with a post or a large piece of tooth inside it, bring it with you.
Lake Stevens Dental offers same-day or next-day emergency appointments when available for concerns like tooth pain, swelling, broken teeth, lost restorations, and other urgent dental problems.
What Lake Stevens Dental may check
At your visit, the dentist may look at several things:
- Whether the tooth has new decay
- Whether the remaining tooth structure is strong enough
- Whether the crown still fits
- Whether the bite contributed to the problem
- Whether a crack is present
- Whether the nerve of the tooth is irritated or infected
- Whether a new filling, new crown, root canal, extraction, or replacement option should be discussed
The next step depends on the tooth, not just the fact that a crown or filling came out. A small lost filling may be repairable with a new filling. A crown that came loose because of cement failure may be simpler than a crown that came off because the tooth underneath broke or decayed.
Can the same crown or filling be reused?
Sometimes a crown can be recemented, but not always.
A crown may be reusable when
The crown is intact, the tooth underneath is not decayed or fractured, the fit is still accurate, the bite is stable, and there is enough healthy tooth to support it.
A crown may need replacement when
There is decay underneath, the tooth changed shape, the edge no longer seals well, or the crown itself is damaged.
Fillings are different. Once a filling comes out, it usually needs to be replaced rather than put back in. The dentist will check the tooth and recommend a repair based on the size of the missing filling and the health of the surrounding tooth.
How to reduce the chance of it happening again
Crowns and fillings can fail for several reasons, including decay around the edges, heavy biting forces, grinding, sticky foods, old restorations, or a tooth that has weakened over time.
- Keep up with regular exams and cleanings
- Call early if food catches around a crown or filling
- Avoid chewing ice or very hard objects
- Wear a nightguard if one is recommended for grinding
- Do not ignore sensitivity or bite changes
- Replace failing dental work before it becomes an emergency when possible
Call Lake Stevens Dental for guidance
A lost crown or filling is easier to handle when you know what to do next. Save the piece if you have it, avoid chewing on that side, and call before trying a risky home fix.
FAQ
Is a lost crown a dental emergency?
It can be. If there is severe pain, swelling, infection signs, a broken tooth, or pain when biting, call promptly. If there is no pain, the tooth should still be checked soon so it does not break or decay further.
Can I put my crown back on myself?
Do not force it. If it slips on easily and your dentist advises temporary cement, that may be an option in some cases. Do not use super glue or household adhesive.
What if my tooth is sensitive after the filling came out?
Sensitivity is common when tooth structure is exposed. Avoid chewing on that side, keep it clean, and call for an exam. Sensitivity that lingers, worsens, or comes with swelling should be checked promptly.
Will I need a root canal if my crown falls off?
Not always. A root canal may be discussed if the tooth nerve is infected, inflamed, or exposed, but many lost crowns or fillings can be treated without root canal therapy. The dentist needs to evaluate the tooth first.
What should I bring to my appointment?
Bring the crown or broken piece if you have it. Also mention when it came out, whether it hurts, what makes it worse, and whether you have swelling, drainage, or bite pain.
