Why Does My Crown Hurt When I Bite Down?
A crown, or dental crown, is a cap placed over a damaged tooth to restore its shape, strength, and appearance. If your crown hurts when you bite down, it's crucial to address the issue promptly. This discomfort can indicate a variety of problems, some minor and easily fixable, others more serious requiring immediate dental attention.
This guide explores the common reasons why a crown might hurt when biting down, providing insights into potential causes and recommended actions.
Is it the Crown Itself or the Underlying Tooth?
The first question to ask yourself is: is the pain coming directly from the crown, or is it originating from the tooth underneath? This distinction is critical in determining the cause and appropriate treatment. Pain directly in the crown may suggest a problem with the crown's fit or material. Pain emanating from under the crown points towards issues with the underlying tooth structure.
Possible Causes of Crown Pain When Biting Down:
-
Poor Crown Fit: An ill-fitting crown can cause significant discomfort, especially when biting. Improper cementation can lead to food particles becoming trapped under the crown, irritating the gum tissue and leading to pain. A crown that's too high or too low can also cause discomfort during biting.
-
Fractured Crown: A crack or fracture in the crown itself can create pressure points that exacerbate pain when biting down. This is a common issue, especially if the crown is older or has experienced significant force.
-
Underlying Tooth Decay or Infection: This is a serious concern. Even after crown placement, the underlying tooth might develop decay or infection. This often leads to throbbing pain, particularly when biting down, and can potentially result in the need for root canal treatment.
-
Gum Irritation or Inflammation: Inflammation or infection of the gums around the crown (periodontitis) can press on the crown and cause pain when chewing.
-
Loose Crown: A crown that becomes loose can cause pain and discomfort. Food particles may get trapped under the crown which can also trigger pain and infection.
-
Sinus Infection: While less common, a sinus infection can sometimes radiate pain into the upper teeth and jaws, causing a sensation of pain when biting down, particularly in the upper molars.
What to Do If Your Crown Hurts When Biting Down:
Don't delay seeking professional dental care. The pain could indicate a significant problem that worsens over time. Here's what you can do:
- Contact your dentist immediately. Schedule an appointment to have the crown examined and diagnosed.
- Avoid chewing on the affected side. This reduces the pressure and potential further damage.
- Over-the-counter pain relievers: You can take over-the-counter pain medication (like ibuprofen) to manage the discomfort temporarily before seeing your dentist. Do not rely on pain relievers as a long-term solution.
Can a Loose Crown Be Fixed?
Yes, a loose crown can often be re-cemented by your dentist. The procedure is usually relatively quick and painless.
Can a Cracked Crown Be Repaired?
Depending on the extent of the damage, a cracked crown may be repairable. However, in some cases, it might be necessary to replace the crown entirely.
How Long Does a Dental Crown Last?
Dental crowns typically last 10-15 years, but with proper oral hygiene and regular dental checkups, they can last much longer.
