What to Do If Your Crown Fell Out
If your crown fell out, save it, gently rinse it, and call your dentist for an evaluation. Avoid chewing on that side. Do not use superglue. If the tooth is not painful and the crown seats fully, an over‑the‑counter temporary dental cement can help hold it until you are seen.
You bite into caramel, and your crown pops off at lunch. This usually happens when the cement weakens, decay sneaks under an edge, or the bite and clenching forces exceed the adhesive hold. If the crown and tooth are intact, it can often be cleaned and re-cemented. If you are unsure about materials or options, you can also learn about common crown materials to understand how they behave under stress.
- Find the crown. Rinse it and the tooth gently with water; do not scrub.
- Check for debris inside the crown. A soft toothbrush can remove loose cement.
- Test the fit without force. It should feel snug and fully seat in one position.
- If comfortable, use temporary dental cement from a pharmacy. Avoid household glues.
- Protect sharp edges with dental wax if you cannot reseat it.
- Eat soft foods, skip sticky or hard items, and keep the area clean with gentle brushing.
- Seek urgent care if there is significant pain, swelling, or the tooth feels fractured.

Common Reasons Why Crowns Come Off
Crowns usually come off when the bond between the tooth and the cement fails, or when the tooth underneath can no longer support the crown. If your crown fell out, frequent causes include hidden decay at the margin, strong chewing or grinding forces, and a tooth that is too short or tapered to hold the crown securely. Material and technique factors can play a role as well.
Tooth decay under a crown can slowly dissolve the cement and weaken the grip. Even a small cavity at the edge lets bacteria and fluids leak in, loosening the cement over time. Teeth that had large fillings or root canal therapy may have less remaining structure, so the crown depends more on the shape and a secure “collar” of tooth for retention. When that collar is too short or thin, the crown is more likely to loosen. You floss after dinner and the crown slides off.
Forces matter, too. Heavy clenching, nighttime grinding, and a high bite spot can fatigue the cement and rock the crown loose. Sticky candies, taffy, or even removing floss by snapping upward can pull on a crown, especially on temporaries. When the bite is carefully adjusted and protective habits are in place, crowns tend to last longer. If grinding is part of the picture, see our guide to night guards to understand how they protect teeth and restorations.
Cement and surface preparation also influence retention. Moisture contamination during bonding, a very smooth inner crown surface without proper treatment, or using a cement not suited to the material can reduce hold. Over many years, wear at the edges and repeated thermal changes can compound these effects. At your visit, we evaluate the tooth, the crown’s fit, and the bite to decide whether cleaning and re-cementing is reliable or if a new crown would be more predictable. Early evaluation helps you avoid fractures and sensitivity.
How to Fix a Loose Crown Temporarily
If your crown fell out or feels loose, you can stabilize it briefly at home. Clean the crown and tooth, try the crown in to verify the correct orientation, then use an over-the-counter temporary dental cement as directed. If it will not seat fully or feels high, do not force it; keep the crown safe and call your dentist.
The crown wiggles during dinner, and you feel sudden cold sensitivity. Rinse the crown and the tooth with water, then gently dry both with gauze or a tissue before trying it in. Practice the fit without cement so you know the exact position. When ready, place a small amount of temporary cement inside the crown, seat it in one motion, and hold light pressure with your fingers while it sets. Wipe away extra cement around the edges with a cotton swab or floss by sliding it out sideways to avoid dislodging the crown.
If you cannot get a comfortable, fully seated position, leave the crown out. Store it in a clean container so it is not lost. To reduce sensitivity on the exposed tooth, dab a small amount of sensitivity toothpaste or fluoride gel on the surface and sip room-temperature water. Avoid sleeping with a loose crown in place so you do not accidentally swallow it. If the bite feels uneven after temporary cementing, remove the crown and wait for care.
Keeping the area clean helps the tooth and crown. Gently brush the tooth and adjacent gums twice daily, and swish with warm saltwater to soothe tissues. Watch for signs that need prompt attention, such as ongoing pain, a sharp edge that cuts the tongue, or pieces of the crown or tooth breaking off. For step-by-step guidance during urgent situations, see our overview of dental emergencies. When stabilized early, teeth and crowns fare better long term.
Using Temporary Cement for Crowns
Temporary dental cement can hold a loose or fallen crown in place for a short time. It protects the tooth and helps you chew more comfortably until a dentist can evaluate the fit and the cause. It is not a permanent fix, and it should only be used when the crown seats fully without force and the tooth is not painful.
There are two common categories of temporary cements: eugenol-based and non‑eugenol. Non‑eugenol products are often preferred if the crown may later be bonded with resin, because eugenol can reduce resin adhesion. Use only a small amount, about pea sized, after gently cleaning the inside of the crown and the tooth. Keep the area as dry as you reasonably can, seat the crown in a single motion, and hold light pressure while it sets per the label. Avoid biting on the tooth until the cement has fully hardened.
There are times you should not use temporary cement. Do not cement a crown that will not seat completely, rocks, or feels high when you gently close. Skip cementing if you have moderate or sharp pain, swelling, a cracked crown or tooth, or if the crown belongs to a dental implant. An implant crown that loosens needs professional attention, not over‑the‑counter cement. It pops off during a weekend trip, and you are worried about dinner plans.
After temporary cementing, chew on the other side and keep your bite light on that tooth. Brush the edges carefully to remove excess cement so it does not irritate the gums. If you are sensitive to clove‑like flavors, choose a non‑eugenol option, since eugenol can bother some tissues. If the crown loosens again, remove it so you do not accidentally swallow it, store it in a clean container, and schedule care. A clinical visit lets us check the tooth, clean the surfaces, adjust the bite, and decide on reliable recementing or replacement. Prompt evaluation supports comfortable chewing and predictable repairs.

Steps to Re-Cement Your Crown
If your crown fell out, these steps can stabilize it until your visit. Only proceed if the crown seats fully in a single orientation and the tooth is comfortable. Use an over-the-counter temporary dental cement, and plan to see a dentist soon for definitive care. It pops off during a video call.
Rinse the crown and tooth with water, then gently pat both dry. Try the crown in without cement to confirm the exact orientation; it should drop into place and feel snug. Practice over a towel so you do not lose it. Place a small dot of temporary cement inside, avoiding overfilling. Seat the crown in one motion with fingertip pressure, hold steady as directed on the package, and keep your teeth slightly apart while it sets. Once firm, wipe away visible excess around the edges with a cotton swab, then brush lightly to smooth the margin.
Check the bite by closing gently. If it feels high, remove the crown before the cement hardens fully and wait for care. Do not re-cement if the crown rocks, will not fully seat, or if pieces of tooth or a post are loose inside the crown. Bleeding gums or ongoing pain are also reasons to pause. For implant restorations, loose parts often indicate a screw or abutment issue, which needs professional tightening, not temporary cement.
After placement, chew on the other side and keep the area clean. Sleep without heavy pressure on that tooth, and avoid sticky foods. Even when the crown seems stable, the cause of the looseness still needs diagnosis, such as decay or a bite interference. Set an appointment so the tooth and crown can be cleaned, checked, and permanently secured or replaced. A careful temporary fix buys time, not a cure.
Signs You Need Professional Help
Seek dental care promptly if the tooth hurts, the gum swells, or the crown will not seat fully. Ongoing sensitivity to hot or cold, pain when biting, or a bad taste from the area are also red flags. If your crown fell out and you notice any fracture, looseness of the tooth, or fever, call for an exam.
Lingering or throbbing pain can signal nerve irritation or infection that temporary measures cannot fix. Swelling, a pimple on the gum, or drainage often means bacteria are trapped under the crown or in the tooth. You wake at night with throbbing beneath the exposed tooth. These situations need diagnosis and, at times, antibiotics or root canal care rather than recementing. If the tooth edge is sharp and cutting your tongue or cheek, that is another reason to be seen soon.
If the crown rocks, sits high, or only partly seats, do not force it. A high bite can crack teeth or damage the opposing tooth. Dark staining, softness, or a hole at the margin suggests decay, which must be cleaned before any secure recementing. For implant crowns, looseness often points to a screw or abutment problem and should be tightened professionally, not glued. While you wait, gentle cleaning and soft foods help; for short-term comfort ideas, see our toothache relief guide.
Repeat crown loss is also a sign to come in, since the underlying tooth may be too short, tapered, or decayed to hold a crown reliably without additional treatment. A timely evaluation lets us check the tooth, the crown’s fit, and your bite, then decide on dependable next steps. Prompt evaluation supports comfortable chewing and a stable repair.
When a Crown Came Off During Eating
If your crown fell out while eating, stop chewing, spit out any food in your mouth, and look for the crown. Rinse the crown and your mouth with water, then keep the crown in a clean container or in milk so it does not dry out. Avoid chewing on that side and arrange an evaluation as soon as you can.
You bite into a chewy snack and feel the crown slide free. First, check that you did not swallow it. If you swallowed it and you are breathing normally, it typically passes on its own; if you cough persistently, feel short of breath, or think it went “down the wrong pipe,” seek urgent care. If you still have the crown, do not scrub it. Gently rinse away food debris and set it aside until a dentist can check the fit and the tooth.
Food can wedge under a loose crown and pull it off, or the bite may have shifted just enough to pop it free. Sensitivity right after a crown comes off is common because the underlying tooth is exposed. To protect soft tissues from a sharp edge, place a small piece of orthodontic wax or sugar‑free gum over the area. Brush the area gently after meals, and swish with warm saltwater to soothe the gums. When you clean between the teeth, pull floss out to the side rather than up to avoid tugging on the spot; if you want tips on gentle technique, see our guide to flossing.
Until your visit, choose soft, cool foods and avoid sticky or hard items. Bring the crown to your appointment, since many can be cleaned and re‑secured if the tooth and crown are intact. If the crown looks cracked, if a piece of tooth is inside it, or if the tooth hurts to bite, tell your dentist so the plan can be adjusted. Quick attention helps you return to normal meals without worry. Early, careful care keeps chewing comfortable and predictable.
Caring for Your Tooth After Crown Loss
If your crown fell out, keep the tooth clean, reduce chewing pressure, and arrange a prompt exam. Store the crown safely and avoid sticky or very hard foods. If the crown does not fit perfectly at home, keep it off until we evaluate it.
After a crown comes off, the inner tooth can be sensitive because dentin is exposed to air, cold, and touch. You sip iced tea and the tooth zings. Limiting extremes of temperature, choosing softer foods, and sipping room‑temperature drinks can reduce irritation. Because the surface is unprotected, plaque and sugars reach the dentin more easily, so careful hygiene and fewer sugary snacks help prevent new decay while you wait.
Protecting the tooth also lowers the risk of breakage. Without the crown’s support, chewing forces can chip edges or crack weakened areas, especially on teeth that already had large fillings. Try to chew on the other side, and keep your bite light on the exposed tooth. If you use an oral pain reliever, follow the label and avoid placing aspirin directly on the gum or tooth.
Clean gently twice daily with a soft toothbrush. Angle the bristles toward the gumline to sweep away plaque without scrubbing the exposed surface. If flossing near the area, guide the floss out to the side to avoid tugging on the tooth. A fluoride toothpaste can help protect the dentin; let a thin layer sit for a minute before rinsing.
Bring the crown to your visit. We will check the tooth for decay or cracks, assess the fit, and test the bite. Sometimes a simple cleaning and re‑cementing is reliable. Other times a build‑up, a new crown, or more definitive treatment is needed to restore strength and seal. Taking these steps helps keep the tooth comfortable and ready for a predictable repair.
Preventive Tips to Avoid Future Issues
Good habits make crowns last longer. Keep the edges of the crown very clean, use a fluoride toothpaste daily, and see your dentist on a regular schedule for exams and bite checks. Limit sticky, hard foods that tug or overload the crown, and protect against nighttime grinding with a custom guard if needed. If dry mouth is an issue, manage it to reduce decay risk around the margins.
Why these steps matter: decay often starts at the crown’s edge, where plaque and acids can sneak under the margin and weaken cement. Heavy clenching adds sideways forces that slowly loosen the bond. A high spot in your bite can rock a crown, and frequent snacking bathes the area in sugars, feeding cavity-causing bacteria. You crunch ice during a meeting, and the crown feels strained.
At home, angle your brush toward the gumline and make short, gentle strokes around the crown rim. Clean between teeth daily and withdraw floss by sliding it out rather than lifting, which helps avoid tugging. Consider a prescription-strength fluoride toothpaste if you have a history of cavities. Choose water between meals, keep sweets to mealtimes, and skip very sticky candies that cling to crown edges. If your mouth feels dry or you take medications that reduce saliva, review practical options in our dry mouth resource.
In the office, ask for a bite assessment after any new restoration and periodically thereafter. Small adjustments can reduce rocking forces that lead to loosening. If you grind, a well-fitted night guard cushions teeth and crowns, and should be checked for wear over time. Regular exams let us spot early margin changes or leakage before a bigger problem develops. With these steps in place, you are far less likely to say your crown fell out again. Proactive care supports durable crowns and comfortable chewing.
When to Call a Dentist After Losing a Crown
If your crown fell out, call a dentist as soon as you can. Same-day contact is important if you have pain, swelling, a sharp edge, or the crown will not seat. If you are comfortable and the crown fits fully, schedule a visit within a few days so the tooth can be cleaned and secured.
It pops off on a Sunday morning. Timing matters because the underlying dentin can be sensitive and collects plaque easily. Without the crown, chewing forces may chip the tooth, and the gums can swell around the margin, making re-seating harder. Teeth can also shift slightly, so a crown that fits today may not fit well next week. Calling promptly helps protect the tooth and preserves options.
There are a few special situations that warrant faster care. If biting hurts, that can signal a cracked tooth or a high spot that needs adjustment. A bad taste, drainage, or a pimple on the gum suggests infection and requires evaluation rather than recementing. If the crown belongs to a dental implant, avoid over-the-counter cement; looseness usually means a screw or abutment needs professional tightening. When a piece of tooth is stuck inside the crown, the tooth likely needs rebuilding before any secure placement.
When you call, let the office know whether the crown still fits, whether you swallowed it, and if cold or biting triggers pain. Bring the crown in a clean container to your visit. If you used temporary cement and the bite feels high or the crown rocks, remove it and keep it safe until your appointment. While you wait, keep the area clean, choose soft foods, and avoid sticky items. Quick contact now makes treatment simpler and more predictable later.
Short takeaway: Sooner is better, especially with pain, swelling, or a poor fit.
Frequently Asked Questions
Here are quick answers to common questions people have about What to Do If Your Crown Fell Out in Glendale, AZ.
- What should I do first if my crown falls out?
If your crown falls out, the first step is to locate the crown and rinse it gently with water. Avoid using any soap or scrubbing tools, as these might damage the crown. Once cleaned, place it in a container for safekeeping and avoid chewing on the affected side. It’s also wise to call your dentist promptly to schedule an appointment for a professional evaluation and possible recementing.
- Are there any household items I can use to temporarily fix a crown?
Avoid using any household glues, such as superglue, to fix a crown, as these are not safe for dental use. Instead, use over-the-counter temporary dental cement available at pharmacies. This type of cement is specifically designed to hold dental crowns temporarily and is safe for oral use. Remember to contact your dentist soon after for a more permanent solution.
- How can I protect my tooth if the crown is off?
To protect your tooth when the crown is off, maintain good oral hygiene by gently brushing the exposed area with a soft toothbrush and fluoride toothpaste. Avoid sticky and hard foods that could further damage the tooth. If the tooth is sensitive, apply a bit of sensitivity toothpaste or fluoride gel. Using dental wax or sugar-free gum can also help cover any sharp edges and protect soft tissues.
- When is it safe to use temporary dental cement on a crown?
You can use temporary dental cement when the crown fits snugly and you experience no pain. It should be used only when the crown seats fully and comfortably in one correct orientation. Do not proceed with cement if the crown feels loose or if there is sharp pain or swelling. For longer-term solutions or if unsure, contact your dental provider.
- Why are crowns more likely to come off during eating?
During eating, especially when consuming sticky or chewy foods, the forces and movements on the teeth can dislodge a crown. Foods like caramel, taffy, and hard candies can stick to or pull on a crown, especially if there’s any weakness in the cement or underlying tooth. Even minor shifts in bite pressure or patterns can also pop a crown off.
- How can I prevent my crown from falling out again?
To prevent your crown from falling out again, maintain excellent oral hygiene, including brushing and flossing around the crown to keep plaque from building up. Limit sticky and hard foods that can tug on the crown. Regular dental visits for check-ups and bite adjustments can further extend your crown’s life. Consider wearing a night guard if you grind your teeth at night.
- Is it an emergency if my crown falls out?
While not always a severe emergency, you should contact a dentist promptly if your crown falls out, especially if you experience pain, swelling, or a sharp edge. An unprotected tooth can be sensitive and is prone to damage without the crown. Timely dental evaluation ensures the tooth remains healthy and can be secured back in place effectively.
- What might cause a dental crown to loosen or fall off?
Several factors can cause a crown to loosen or fall off: weakening of the cement bond, decay forming at the edge of the crown, heavy biting, grinding at night, or a crown inadequately fitting due to a tooth being too short or tapered. High-force foods like sticky candies or hard foods can also contribute to a crown coming off.
