A dental crown coming off is not a panic situation, but it is time-sensitive. In the first 24 hours: recover the crown if you can, keep it clean and dry, avoid chewing on that side, and call our office as soon as possible. If we see you within a day or two, we can often re-cement the same crown rather than having to make a new one — a difference of hundreds of dollars and one visit versus two or three.

The 5 Steps to Take Right Now

1. Recover the crown if you can. Look for it. It is usually still in your mouth or in the food you were eating when it came loose. Rinse it gently under lukewarm water, dry it, and store it in a small container or plastic bag — not a tissue, which gets thrown away by accident.
2. Rinse your mouth with warm salt water. Half a teaspoon of salt in a cup of warm water. Swish gently. This cleans the exposed tooth and reduces sensitivity.
3. Avoid the tooth. Chew on the other side. The tooth structure underneath a crown (called the “abutment” or “prepared tooth”) is much smaller and weaker than a natural tooth. Biting on it can crack it, which turns a re-cementing appointment into a much bigger job.
4. Skip sticky, hard, or very hot/cold foods for now. Sensitivity is normal until the crown is back on.
5. Call our office. (407) 678-8848. Tell whoever answers that a crown came off. We prioritize these appointments and can usually see you same-day or next-day.

Why a Crown Comes Off in the First Place

Crowns don’t come off randomly. In most cases, one of five things has happened:

The cement has worn out

Dental cement lasts a long time, but not forever. Ten to fifteen years is typical for well-placed crowns. If the crown is that old and the tooth underneath is healthy, re-cementing is often the entire fix.

Decay has formed under the crown

The most common reason a crown fails in the first 5–10 years. Bacteria worked their way under the crown edge and softened the underlying tooth, so the cement no longer has solid tooth structure to grip. This requires cleaning out the decay before any new crown can be placed.

The tooth underneath fractured

The tooth structure holding the crown gave way. This is the situation we want to catch early — a fracture that extends below the gumline may not be restorable, and time matters.

Bite pressure has shifted

Grinding, clenching, or a new filling on an opposing tooth can change how bite forces land on the crown. Over time this loosens it.

The original fit was marginal

Rare, but it happens. If a crown falls off within the first year of placement, this is usually the reason — and any competent dentist will replace it under their own warranty.

When It IS Actually an Emergency

Most fallen crowns can wait 24–48 hours. Come to us urgently — not next week — if any of these apply:

• Sharp pain from the exposed tooth. Sometimes the underlying tooth has a nerve exposure or fracture. Waiting can cause the pain to escalate significantly.
• Visible tooth fracture. If you can see that the tooth underneath has broken, the sooner we assess, the more of that tooth we can save.
• Bleeding from the tooth site. Suggests soft tissue damage or a deeper fracture.
• Front tooth crown. Cosmetic emergency for most patients — we prioritize front-tooth crown reattachment for that day.
• Swelling near the tooth. Could indicate an existing infection that became active when the crown came off. Needs to be seen quickly.

Our office line is (407) 678-8848. We answer during business hours (Monday–Friday, 7:00am–2:30pm). After hours, leave a message and Dr. Rezkalla or Dr. Altomare’s on-call team returns urgent calls within the hour.

What to Expect at the Appointment

Our first move is to examine the tooth underneath the crown and evaluate the crown itself. Three possible outcomes:

Re-cementing (best case, most common)

The tooth is intact, the crown is intact, and the underlying issue was old cement. We clean both surfaces, apply new bonding cement, and set the crown. Usually one visit, roughly the cost of a limited exam plus the re-cement fee.

New crown on same tooth

The crown is damaged or no longer fits, but the underlying tooth is restorable. We take an impression or digital scan, place a temporary, and fit the new crown at a follow-up visit two to three weeks later. Larger cost, but the tooth is saved.

Additional treatment first

Decay, fracture, or infection under the crown needs to be treated before any new crown goes on. That might mean a filling, a root canal, or in the case of severe tooth loss, an implant or bridge to replace the tooth entirely. Dr. Rezkalla walks you through every option and its cost before treatment starts.

Common Questions About Fallen Dental Crowns

Can I superglue my dental crown back on?

No. Superglue is toxic in the mouth, doesn’t bond correctly to dental materials, and often makes it impossible for the dentist to re-cement the same crown properly. Store the crown in a clean container and see the dentist. Over-the-counter temporary dental cement (Dentemp) is acceptable for a day or two if you cannot get to the dentist right away, but even that is a stopgap, not a solution.

How long can I go without a dental crown?

A few days is fine if the underlying tooth is not painful and you can avoid chewing on that side. Beyond a week or two, the exposed tooth is at real risk — it can shift position (making the original crown no longer fit), fracture, or develop rapid decay. Aim to be seen within 3–5 days.

Is it painful when a dental crown falls off?

Usually not painful on its own, but the exposed tooth is often very sensitive to temperature (hot and cold liquids especially) and sometimes to air and pressure. Warm salt-water rinses and avoiding the tooth with food help.

Will insurance cover a fallen dental crown?

It depends on the crown’s age and your specific plan. Most dental insurance covers a new crown once every 5–7 years per tooth. If your crown is older than that, coverage is likely. If it is younger, some plans cover a “replacement” if there is a valid clinical reason (decay, fracture) but not for straightforward wear. Re-cementing an existing crown is usually covered separately and inexpensively. Our team helps verify your specific benefits at the appointment.

Can a crown be re-cemented or does it need replacement?

If the crown is intact and the underlying tooth is healthy, re-cementing is usually possible and preferred. If either the crown or the underlying tooth has been damaged, replacement becomes the safer long-term option. Dr. Rezkalla or Dr. Altomare determines this at the exam based on what they see.

What if the tooth underneath is now broken?

The urgency increases, but options remain. A minor fracture at the crown margin may be restorable with a new crown build-up. A deeper fracture may require a root canal plus a new crown, or in more advanced cases, extraction followed by an implant or bridge. The earlier we see it, the more of the natural tooth structure we can preserve.
