A crown is designed to protect a damaged tooth, restoring its function and appearance. However, sometimes a tooth with a crown can still experience pain. This can be unsettling, as it suggests something isn't quite right. Understanding the potential causes is crucial for addressing the issue promptly and effectively. This article explores the various reasons why a crowned tooth might hurt and what you should do about it.
What are the Possible Causes of Pain Under a Dental Crown?
Pain under a dental crown can stem from several sources, often requiring a professional diagnosis. Let's examine some of the most common culprits:
1. Irritation or Infection of the Tooth Pulp (Pulpitis):
Even with a crown, the underlying tooth structure can still become infected or irritated. This often happens if decay wasn't completely removed before the crown was placed, or if bacteria seeped under the crown over time. Symptoms can include spontaneous pain, sensitivity to hot or cold, and persistent throbbing.
2. Periodontal Disease (Gum Disease):
Gum disease can affect teeth with crowns just as easily as natural teeth. Inflammation and infection around the gumline can lead to pain, sensitivity, and potentially bone loss. This is especially important to address since periodontal disease can lead to crown loosening or even loss.
3. Cracked Tooth Syndrome:
A crack in the underlying tooth might not have been detected before the crown was fitted. This can become aggravated over time, leading to pain, particularly when biting down. Sometimes, the crown itself might even be cracked.
4. Abscess Formation:
A bacterial infection that has created a pus-filled pocket at the root of the tooth is known as an abscess. This is extremely painful and requires immediate professional attention. Symptoms include severe, throbbing pain, swelling, and sometimes fever.
5. Sinusitis:
While seemingly unrelated, sinus infections can sometimes cause referred pain, which can be felt in the upper teeth. If the pain is accompanied by other sinus symptoms like nasal congestion and pressure, a sinus infection is a potential cause.
6. Poor Crown Fit or Cement Failure:
Over time, the cement holding the crown in place might wear down or fail, creating a gap between the crown and the tooth. This can lead to sensitivity and pain.
7. Trauma to the Tooth:
A recent impact or injury to the tooth, even a seemingly minor one, could cause inflammation or damage under the crown, leading to pain.
What Should You Do If Your Crowned Tooth Hurts?
Don't ignore pain associated with a crowned tooth. Prompt professional care is crucial to prevent more serious complications. Schedule an appointment with your dentist as soon as possible. They will be able to:
- Conduct a thorough examination: Your dentist will perform a visual examination, possibly taking X-rays to assess the underlying tooth structure.
- Diagnose the cause of the pain: They will use various diagnostic tools to determine the underlying issue.
- Recommend appropriate treatment: Depending on the cause, treatment options might range from cleaning and polishing to root canal therapy, crown replacement, or periodontal treatment.
Ignoring pain from a crowned tooth can lead to more significant issues down the line, including tooth loss. Seeking prompt professional dental care is the best approach to managing this discomfort and preserving the health of your teeth.
