A crown is designed to protect and strengthen a damaged tooth, but sometimes, even with a crown in place, pain can persist or develop. This can be frustrating and worrying, so let's explore the potential reasons why your crowned tooth might be hurting.
What Could Be Causing the Pain Under My Crown?
Several issues can lead to pain in a tooth with a crown. It's crucial to see your dentist for a proper diagnosis and treatment plan, as self-treating can worsen the problem. However, understanding the possibilities can help you prepare for your appointment.
1. Irritation or Infection of the Tooth Pulp (Pulpitis):
Even with a crown, the underlying tooth structure, including the pulp (the soft tissue containing nerves and blood vessels), can become inflamed or infected. This is often caused by decay that wasn't completely removed before the crown was placed, or by a new cavity forming underneath the crown. Symptoms can range from mild discomfort to severe throbbing pain, especially when chewing or biting.
2. Periodontal Disease (Gum Disease):
Gum disease, characterized by inflammation and infection of the gums, can affect teeth with crowns. Bacteria can build up along the gum line, even under the crown's margin, causing irritation and pain. Swelling, redness, and bleeding gums are also common signs.
3. Cracked Tooth Syndrome:
A cracked tooth, even one seemingly well-protected by a crown, can cause significant pain. A hairline fracture, unseen during initial treatment, might be the culprit. This crack can extend under the crown, leading to discomfort when chewing or biting, or even spontaneous pain.
4. Abscess Formation:
An abscess is a pocket of pus that forms at the root of a tooth due to infection. This can be incredibly painful and requires immediate dental attention. Symptoms can include intense pain, swelling, and sensitivity to pressure.
5. Problems with the Crown Itself:
Occasionally, the problem isn't with the tooth itself, but with the crown. A poorly fitting crown can irritate the surrounding gum tissue, causing discomfort. A fractured or loose crown can also lead to pain and sensitivity.
6. Tooth Sensitivity:
Sensitivity to temperature (hot or cold) or pressure is common after dental work, but persistent or severe sensitivity under a crown may indicate an underlying problem.
7. Sinusitis:
While less directly related to the tooth itself, sinus infections can sometimes cause referred pain that feels like a toothache, particularly in the upper teeth.
How Can I Tell What's Wrong with My Crowned Tooth?
It's impossible to accurately diagnose the cause of pain under a crown without a professional dental examination. However, paying attention to the characteristics of your pain can help your dentist make a diagnosis:
- Type of pain: Is it sharp, throbbing, dull, or aching?
- Intensity of pain: Is it mild, moderate, or severe?
- Duration of pain: Is it constant or intermittent?
- Location of pain: Is the pain localized to the crowned tooth, or does it radiate to other areas?
- Triggers: Does the pain worsen with chewing, biting, hot/cold temperatures, or sweet foods?
What Should I Do If My Crowned Tooth Hurts?
Schedule an appointment with your dentist immediately. Don't delay seeking professional help. Ignoring dental pain can lead to more serious problems and more extensive (and costly) treatment down the line. Your dentist will conduct a thorough examination, possibly including X-rays, to determine the cause of your pain and recommend the appropriate treatment.
