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 after getting a crown or even years later isn't uncommon. Understanding the potential causes of crown pain is crucial for seeking appropriate treatment. This comprehensive guide explores various reasons why your crown might hurt and what you should do.
What are the Common Causes of Crown Pain?
Crown pain can stem from several sources, and pinpointing the exact cause requires professional dental evaluation. However, some frequent culprits include:
-
Irritation of the Gums: The gum tissue surrounding the crown can become irritated or inflamed, leading to discomfort. This can be caused by poor oral hygiene, ill-fitting crowns, or underlying gum disease. Inflammation may manifest as throbbing pain, sensitivity to touch, or redness and swelling around the crown.
-
Tooth Decay Under the Crown: Despite the protective nature of a crown, decay can sometimes occur beneath it if the tooth wasn't properly prepared before the crown was placed or if bacteria manage to penetrate the seal. This hidden decay can cause significant pain and potentially necessitate crown removal and further treatment.
-
Pulpitis (Inflammation of the Tooth Pulp): If the underlying tooth's pulp (the soft tissue containing nerves and blood vessels) becomes inflamed or infected, it can cause intense pain, even with a crown in place. This inflammation can stem from deep decay, trauma, or other dental issues.
-
Cracked or Loose Crown: Over time, a crown might crack or become loose. This can expose the underlying tooth to bacteria, leading to sensitivity and pain, especially when chewing or biting. A loose crown might also cause a noticeable clicking or shifting sensation when you move your jaw.
-
Sinus Infection: Pain in the upper teeth, especially molars, can sometimes be referred pain from a sinus infection. While not directly related to the crown itself, the proximity can make it feel like the crown is the source of discomfort. Symptoms such as nasal congestion, pressure, and facial pain should signal the need to check for a sinus problem.
-
Bite Problems (Malocclusion): An improperly fitting crown can interfere with your bite, causing pain in the jaw, temporomandibular joint (TMJ), or the crowned tooth itself. This is often accompanied by headaches or clicking sounds in the jaw.
Why Does My Crown Hurt After Getting It Placed?
Post-procedure pain is relatively common, typically attributed to:
- Inflammation: The placement procedure itself can cause temporary gum inflammation, resulting in some soreness and sensitivity. This usually subsides within a few days.
- Irritation from the Temporary Cement: The temporary cement used during the procedure can occasionally irritate the gum tissue.
- High Bite: If the bite is too high, it can create pressure on the newly placed crown and cause pain.
If the post-placement pain is severe or persistent, contact your dentist immediately.
How Long Does Crown Pain Last?
The duration of crown pain varies greatly depending on the underlying cause. Mild discomfort from irritation or inflammation might only last a few days. However, pain stemming from infection or a cracked crown can persist for much longer and requires professional dental attention. Don't hesitate to consult your dentist if the pain continues or worsens.
When Should I See a Dentist About Crown Pain?
Don't delay seeking professional help if you experience:
- Severe or persistent pain: Intense, throbbing pain that doesn't subside warrants immediate attention.
- Sudden onset of pain: A sudden, sharp pain suggests a potential problem requiring prompt diagnosis.
- Pain accompanied by swelling or fever: This could indicate an infection needing urgent care.
- Loose or cracked crown: A visibly damaged crown needs immediate repair to prevent further complications.
Ultimately, only a dentist can accurately diagnose the source of your crown pain and recommend the best course of treatment. Ignoring crown pain could lead to more serious dental problems, so don't hesitate to schedule an appointment if you're experiencing any discomfort.
