A crown, or dental crown, is a cap placed over a damaged tooth to restore its shape, strength, and appearance. While crowns are generally durable and long-lasting, experiencing pain when biting down can indicate a problem. This pain can range from a dull ache to a sharp, shooting sensation, and understanding the potential causes is crucial for timely treatment.
What Could Be Causing the Pain?
Several factors can cause pain in a crowned tooth when biting down. Let's explore some of the most common reasons:
1. Inadequate Fit or Cement Failure:
This is a primary culprit. If the crown doesn't fit perfectly, food particles can get trapped underneath, causing irritation and inflammation. Over time, the cement holding the crown in place can weaken or fail completely, leading to discomfort, especially when pressure is applied during biting. This can result in a sensitive or painful bite.
2. Tooth Decay or Infection Under the Crown:
Even with a crown in place, decay can occur underneath, especially if the underlying tooth wasn't properly prepared before the crown was cemented. This decay can lead to infection, abscess formation, and significant pain when biting. Ignoring this can lead to more extensive and costly dental work in the future.
3. Cracked Tooth or Crown:
A crack in the underlying tooth or the crown itself can cause pain when pressure is applied. This crack might be microscopic and difficult to detect without specialized dental tools. The pain is often exacerbated by biting down on hard foods or clenching your teeth.
4. Gum Irritation or Inflammation:
Irritation or inflammation of the gums around the crowned tooth can also contribute to pain when biting. This could be caused by poor oral hygiene, gum disease (gingivitis or periodontitis), or an ill-fitting crown that irritates the gum tissue.
5. Temporomandibular Joint (TMJ) Disorder:
While not directly related to the crown itself, TMJ disorders can cause pain in the jaw and teeth, including pain when biting. This is a more complex issue that requires a different approach to diagnosis and treatment.
What Should I Do If My Crown Hurts When I Bite Down?
Don't delay seeking professional help. Attempting to self-diagnose or treat the problem could worsen the situation. Schedule an appointment with your dentist immediately. They can accurately diagnose the cause of your pain and provide appropriate treatment.
People Also Ask (PAA) Questions and Answers:
How long does it take for a crown to stop hurting after placement?
Some minor sensitivity is normal immediately after crown placement. However, persistent or worsening pain should not be ignored. If pain persists for more than a few days, contact your dentist.
Can a loose crown cause pain when biting?
Yes, a loose crown often leads to pain when biting down, as food particles can become trapped, causing irritation and inflammation. The loose crown may also shift, increasing pressure on the underlying tooth and gums.
What are the signs of a cracked tooth under a crown?
Signs may include persistent pain when biting, sensitivity to temperature, and a dull ache that lingers even when not chewing. You might also notice swelling or discoloration of the gums around the crown.
Can a crown cause pain permanently?
No, a properly placed and well-maintained crown shouldn't cause permanent pain. Pain is usually a sign of an underlying issue, such as a poor fit, decay, or infection. Addressing the cause of the pain usually resolves the discomfort.
How is a broken crown repaired?
The repair method depends on the extent of the damage. Minor chips might be repaired with bonding, while more significant damage may require a new crown. Your dentist will determine the best course of action.
