What Will Happen When Dental Crowns Fall Out

Dental crowns, also known as caps, are commonly used to restore teeth that are severely damaged, decayed, or discoloured. These caps are designed to match the appearance of your natural teeth, improving both function and aesthetics. Once a permanent crown is bonded to your tooth, it can last for years without requiring much thought. However, this can change if the crown becomes loose or completely detaches—a situation known as “debonding.”

Why Do Dental Crowns Fall Out?

Several factors can cause a dental crown to loosen or fall off:

  1. Sudden Impacts
    An unexpected force, such as biting into a hard or sticky food or experiencing a physical injury, can loosen the crown. While the crown might not come off immediately, damage to its structure or the underlying tooth can lead to its eventual detachment. Teeth grinding (bruxism) can also cause similar long-term stress on the crown.
  2. Tooth Decay Under the Crown
    The small margin where the crown meets your tooth can be prone to decay if oral hygiene is neglected, or if the crown isn’t a perfect fit. A high-sugar diet or poor brushing habits can accelerate decay, weakening the tooth beneath and causing the crown to fall out.
  3. Failed Adhesive Bond Over time, the cement or adhesive holding the crown in place may wear down, leading to the crown loosening. This is one of the most common and easiest problems to fix.

What To Do If Your Crown Falls Out

If your dental crown has fallen out, follow these steps:

  1. Secure the Crown
    First, ensure you don’t accidentally swallow the crown. If you do, it will likely pass harmlessly, but it’s better to avoid this altogether. If you still have the crown, rinse it thoroughly and store it in a clean, small container until you can visit your dentist.
  2. Protect the Exposed Tooth
    Your exposed tooth might feel sensitive to air, temperature, or pressure. Keep the area clean by rinsing your mouth and gently brushing around the affected tooth. Avoid eating or chewing on that side of your mouth.
  3. Temporary Fix
    If the missing crown is at the front of your mouth and you’re concerned about appearance, you can use over-the-counter dental cement as a temporary measure. Avoid using non-dental adhesives like superglue, as these can damage the crown and complicate your dentist’s work.
  4. Visit Your Dentist Contact your dentist as soon as possible to have the crown reattached or replaced. Acting quickly can prevent further complications, such as infection or additional damage to the underlying tooth.

Common Scenarios for Dental Crown Issues

  1. No Tooth Left Under the Crown
    If the crown falls out and there’s minimal or no remaining tooth structure, it’s likely due to severe decay or improper crown placement. This requires immediate attention, as bacteria can invade the weakened area, causing pain and further damage.
  2. Foul Smell or Taste
    A bad taste or odour from the crown is often a sign of decay beneath it. Poor sealing or weakened adhesive can allow bacteria to accumulate. Maintaining excellent oral hygiene and visiting your dentist promptly can prevent this issue.
  3. Crown Fell Out, but the Post Remains
    If your crown detaches but the post stays in place, carefully remove the crown from your mouth to avoid swallowing it. Clean the crown and the affected tooth, and bring the crown to your dentist, who may be able to reattach it if it’s undamaged.
  4. Crown Fell Off at the Gum Line
    A crown that detaches near the gum line may need reapplication or full replacement, depending on its condition. Quick action can help avoid infection or the potential loss of the tooth.
  5. Crown Feels Loose but Is Still Attached
    A loose crown could indicate decay, structural damage, or weakened adhesive. Schedule an appointment with your dentist immediately to secure or replace it.
  6. Permanent Crown Feels Loose If a permanent crown becomes loose, contact your dentist right away. Re-cementing the crown might be all that’s needed, but in some cases, damage to the underlying tooth could require more extensive treatment.

Dental Crowns FAQS

Can I eat or drink after my crown falls out?

It’s best to avoid eating or drinking on the affected side until your crown is repaired or replaced. Chewing hard, sticky, or crunchy foods could worsen the damage to the underlying tooth.

Why is the tooth under my crown discoloured?

A darkened or black tooth beneath the crown could signal tooth decay or damage. This occurs when bacteria seep beneath the crown due to poor sealing or structural issues. Immediate dental attention is necessary.

Can a loose crown be fixed?

Yes, in many cases, a loose crown can be reattached by cleaning both the crown and the tooth, then applying fresh adhesive. However, the tooth’s condition will determine whether the crown can be restored.

Should I pull out a loose crown myself?

Avoid pulling out a loose crown. Doing so can damage the underlying tooth or surrounding teeth. If necessary, use temporary dental adhesive from a drugstore to hold it in place until you can see your dentist.
