Why Does My Crown Keep Falling Off? Troubleshooting Your Loose Crown
A loose dental crown is frustrating and uncomfortable, leaving you worried about eating, speaking, and even smiling. Understanding why your crown keeps falling off is the first step to getting it fixed and preventing future issues. Let's explore the common causes and what you can do.
What are the common reasons for a loose dental crown?
This is a frequently asked question, and the answer often depends on the underlying cause. Several factors contribute to a crown becoming loose. These include:
- Poor Cementation: The most frequent culprit is inadequate cementation during the initial placement of the crown. If the dentist didn't properly prepare the tooth or use enough cement, the crown won't adhere securely.
- Decay or Infection Under the Crown: Bacteria can seep under the crown, causing decay or an infection in the underlying tooth. This can weaken the tooth structure and compromise the crown's stability.
- Trauma or Injury: A blow to the mouth or excessive chewing force can dislodge a crown, especially if the underlying tooth is already weakened.
- Wear and Tear: Over time, the cement holding the crown in place can wear down, especially with years of chewing and exposure to saliva.
- Improper Bite: An improper bite (malocclusion) can put excessive pressure on certain teeth, leading to crown loosening.
- Tooth Fracture: An unseen fracture underneath the crown can compromise its support, causing it to become loose or fall off.
What should I do if my crown falls off?
If your crown falls off, don't panic! Here's what you should do:
- Try to find the crown: Carefully rinse the crown and store it in a safe place, ideally in a container with a small amount of milk or saline solution to keep it moist.
- Contact your dentist immediately: Schedule an appointment as soon as possible. Don't delay, as leaving the tooth exposed can lead to infection or further damage.
- Protect the tooth: If possible, gently place the crown back on the tooth (if it fits comfortably). This will protect the tooth until you see your dentist. If it doesn't fit, try to keep the area clean by rinsing gently.
- Avoid chewing on that side: To prevent further damage, avoid chewing on the side of your mouth where the crown has fallen off.
- Manage any discomfort: Over-the-counter pain relievers can help manage any discomfort until your appointment.
How can I prevent my crown from falling off again?
Prevention is key. Here’s how you can reduce the risk:
- Maintain good oral hygiene: Brush and floss regularly to prevent decay and gum disease.
- Avoid hard foods: Refrain from biting into extremely hard foods like nuts, ice, or hard candies that can put excessive force on your teeth and crowns.
- Wear a mouthguard: If you play contact sports, wear a mouthguard to protect your teeth from injury.
- Regular dental checkups: Schedule regular check-ups and cleanings with your dentist to allow them to monitor the condition of your crowns and address any potential problems early on.
Is it expensive to have a loose crown fixed?
The cost of repairing a loose crown depends on various factors, including the extent of the damage, your location, and your dental insurance coverage. It's best to contact your dentist directly for an accurate estimate.
Remember, prompt action is essential to prevent further damage to your tooth. A loose crown is not something to ignore; see your dentist as soon as possible for a proper diagnosis and repair. Ignoring the problem can lead to more extensive and expensive treatments down the road.
