A crown, or dental crown, is a cap placed over a damaged tooth to restore its shape, strength, and appearance. While crowns are designed to be durable and long-lasting, experiencing pain when biting down can be a significant concern. This discomfort indicates a potential problem that requires professional attention. Let's explore the various reasons why your crown might be hurting when you bite down.
What Causes Crown Pain When Biting Down?
Several factors can contribute to crown pain when biting down. Understanding these potential causes is the first step towards finding a solution.
1. Inadequate Crown Fit or Cement Failure:
This is one of the most common culprits. If the crown doesn't fit perfectly, it can create pressure points that cause pain when you bite down. Over time, the cement holding the crown in place can also fail, leading to movement and subsequent discomfort. This can manifest as sharp, localized pain or a dull ache.
2. Tooth Decay Under the Crown:
Despite the crown's protective layer, decay can still occur beneath it. Bacteria can infiltrate the area between the crown and the tooth, leading to inflammation, infection, and pain, especially when pressure is applied during biting. This can cause a throbbing pain or sensitivity to hot and cold temperatures.
3. Gum Irritation or Infection (Peri-Coronitis):
Irritation or infection of the gums surrounding the crown (peri-coronitis) is another possible cause of pain. This can stem from poor oral hygiene, ill-fitting crowns leading to plaque buildup, or even an allergic reaction to the crown's materials. The pain might be more localized to the gums, but it can also radiate to the crown area, particularly when biting.
4. Cracked or Fractured Tooth Under the Crown:
A pre-existing crack or fracture in the underlying tooth might have been overlooked or worsened. The crown, while protecting the tooth's exterior, can't prevent pain if the tooth itself is damaged. Biting down puts stress on the fractured area, causing intense pain.
5. Temporomandibular Joint (TMJ) Disorder:
While less directly related to the crown itself, TMJ disorders can cause pain that radiates to the teeth and jaw. Problems with the temporomandibular joint, which connects your jaw to your skull, can result in jaw pain, headaches, and even pain that feels like it's originating from a crowned tooth.
6. High Crown:
If the crown is placed too high, it can interfere with your bite and cause pain when you chew. This is often a result of an improper fit and can cause discomfort even without significant pressure.
7. Abscess:
An abscess is a pocket of pus that forms due to an infection. This can occur beneath a crown and cause intense, throbbing pain, often worsened by chewing. An abscess requires immediate dental attention to prevent further complications.
What Should I Do If My Crown Hurts When I Bite Down?
Do not delay seeking professional help. Ignoring the pain can lead to more serious problems. Schedule an appointment with your dentist as soon as possible. They can accurately diagnose the cause of the pain and recommend the appropriate treatment.
Frequently Asked Questions (FAQ):
How long does it take to fix a painful crown?
The time it takes to fix a painful crown varies depending on the underlying issue. Simple adjustments might be completed during a single visit, while more extensive procedures, such as removing and replacing the crown or root canal treatment, might require multiple appointments.
Can I take over-the-counter pain relievers for crown pain?
Over-the-counter pain relievers like ibuprofen or acetaminophen can provide temporary relief from the pain, but they do not address the underlying cause. They should be used sparingly and in conjunction with a visit to your dentist.
How can I prevent future crown pain?
Maintaining excellent oral hygiene, including regular brushing and flossing, is crucial. Regular dental checkups and professional cleanings can help detect and address potential problems early. Avoiding biting down on hard objects can also help to extend the lifespan of your crown.
