It’s never a convenient moment when a dental crown comes loose or falls off, but it happens more often than you might think. If you’ve just found yourself asking, “What do I do?”, don’t panic. Acting quickly and carefully can make all the difference.
The priority is to locate the crown, store it safely, and contact an emergency dentist as soon as possible. Without its protective cover, your tooth is exposed and far more susceptible to sensitivity, damage, and decay – so timely care is key to preventing further complications.
Discovering a lost crown can be alarming, but taking the right steps in the first few minutes can significantly affect the outcome. Following a clear plan protects your tooth and increases the chances of a simple, successful repair.
The moment you realize your crown is loose or has fallen out, the first priority is to locate it. Check your mouth carefully. If you were eating, spit out your food to find the crown.
It’s crucial not to swallow it. If you’ve swallowed the crown, don’t worry; it will pass naturally through your system. However, you’ll need a replacement crown made. Once you find it, handle it with care.
If the crown is still partially attached or loose in your mouth, gently remove it. Leaving a loose crown in place poses a choking hazard. Use clean fingers to carefully wiggle it free.
Never force it or use tools that could damage the underlying tooth structure. Place the crown in a small, hard-sided container, like a pillbox or a small plastic food container, to prevent it from being lost or damaged.
Take a quick look at both the crown and your tooth. Look for:
Is the crown hollow and mostly intact, or is it filled with tooth structure?
Cracks or damage to the crown
Sharp edges on the exposed tooth
Signs of decay or dark spots
Any remaining cement or adhesive
Is the tooth itself chipped or broken?
This information can be helpful when you call our office. If you are experiencing significant pain or bleeding, let our team know.
Rinse your mouth with warm salt water (a half-teaspoon of salt in a glass of warm water). This helps clean the area, soothe the gums, and remove any food debris from the exposed tooth.
If you plan to save the crown for potential reattachment:
Rinse the crown under lukewarm water
Use a soft toothbrush to remove old cement gently
Pat dry with a clean cloth
Store in a small container or plastic bag
You can also gently brush the exposed tooth, being careful not to cause further irritation.
The tooth under your crown is no longer protected by the hard outer enamel and can be very sensitive to temperature, air, and pressure. Several options exist:
Dental cement (available at pharmacies): Apply a small amount inside the crown and gently press it back onto the tooth. This provides temporary protection for a few days.
Dental wax or sugar-free gum: If you can’t reposition the crown, cover the exposed tooth with dental wax or sugar-free gum to shield it from temperature sensitivity and bacteria.
Clove oil: For pain relief, dab a small amount of clove oil on the exposed tooth using a cotton swab. This natural remedy provides temporary numbing.
Never use superglue or other household adhesives to try and reattach the crown. These substances are toxic and can cause irreversible damage to your tooth, potentially making a simple repair impossible.
You should contact a dentist immediately after a crown falls off. Here are the reasons why speed is important:
Further Damage: The prepared tooth is not as strong as a natural tooth and is prone to fracturing or chipping.
Infection and Decay: The exposed dentin is more porous than enamel, making it a prime target for bacteria that cause cavities.
Shifting Teeth: The gap left by the missing crown can allow adjacent and opposing teeth to shift, which can affect your bite and make it difficult or impossible to fit the original crown back on.
Contact Urgent Dental Care right away if you experience:
Severe pain or throbbing
Visible tooth damage or decay
Swelling in the gums or face
Difficulty eating or drinking
Sharp edges cutting your tongue or cheek
When you arrive for your emergency crown repair, our team will focus on providing fast relief and a clear treatment plan. We understand that you’re likely in discomfort and want to resolve the issue as quickly as possible.
Your visit will begin with an urgent dental exam and X-ray. One of our experienced providers will assess the health of the underlying tooth and the condition of the fallen crown.
The exam helps us answer critical questions:
Why did the crown fall off? Was it due to new decay, cement failure, trauma from grinding or clenching, or an issue with your bite?
Is the underlying tooth healthy and structurally sound?
Is the crown itself still in good condition, and does it fit properly?
Based on this evaluation, we will determine the course of action. Treatment options include:
Clean and re-cement your existing crown if it’s undamaged (takes 30-60 minutes)
Create a temporary crown while ordering a permanent replacement
Remove the underlying decay and restore the tooth before a crown can be placed
Perform a root canal if infection is present
Extract the tooth if it’s severely damaged (rare cases)
Our team will explain all your options clearly, ensuring you understand the situation and the recommended treatment. We ensure your comfort throughout the procedure with appropriate numbing medications.
Crowns typically last 10-15 years with proper care. You can take steps to extend the life of your dental restorations and prevent them from coming loose:
Practice Excellent Oral Hygiene: Brush twice daily and floss around the crown’s base where bacteria accumulate. This helps prevent decay from forming at the crown margin, a common cause of failure.
Avoid Harmful Habits: Don’t chew ice, hard candies, very sticky foods like taffy or caramels, or use your teeth as tools. These behaviors stress crowns beyond their design limits.
Address Teeth Grinding (Bruxism): If you grind or clench your teeth, especially at night, the constant pressure can weaken the cement and damage the crown. A custom-fitted nightguard protects crowns from excessive pressure during sleep.
Attend Regular Dental Check-ups: Consistent check-ups are key to identifying potential issues with crowns or other restorations before they become emergencies.
Address Issues Promptly: Don’t ignore sensitivity, pain, or a crown that feels “different” – these warnings often precede crown loss.
