Why Does My Crown Hurt? Understanding Crown Sensitivity and Potential Causes
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 or discomfort in a crowned tooth is unfortunately not uncommon. The reasons for this pain can vary significantly, and accurately pinpointing the cause often requires a visit to your dentist.
This article will explore several potential reasons why your crowned tooth might be hurting, answering some frequently asked questions about crown sensitivity and providing guidance on when to seek professional dental care.
What are the common causes of crown pain?
Several factors can contribute to pain emanating from a crowned tooth. These include:
-
Underlying Tooth Decay or Infection: Even with a crown in place, decay can still occur beneath it. This is especially true if there was inadequate preparation of the tooth before the crown was placed, or if there's a leak at the margin between the crown and the tooth. An infection can lead to severe pain, swelling, and even the need for root canal treatment.
-
Gum Irritation or Infection (Periodontitis): Inflammation or infection of the gums surrounding the crowned tooth can cause pain and sensitivity. Gingivitis or periodontitis, if left untreated, can lead to bone loss and eventual tooth loss.
-
Bite Problems (Malocclusion): An improper bite can put excessive pressure on the crowned tooth, causing discomfort. This can occur due to teeth shifting over time or from an ill-fitting crown.
-
Cracked or Fractured Tooth: Sometimes, a tooth may already be cracked or fractured before the crown is placed. The crown might mask the initial problem, but the underlying damage can continue to cause pain. Even a seemingly well-placed crown can crack or fracture over time, leading to discomfort.
-
Sinus Issues: Pain in the upper molars can sometimes be referred pain from sinus infections. The proximity of the roots of upper molars to the sinuses means that pressure or inflammation in the sinuses can be felt as tooth pain.
-
Crown Cement Irritation: Occasionally, the cement used to attach the crown can irritate the surrounding gum tissue, leading to minor discomfort. This is usually temporary and resolves on its own.
-
Abscess: A collection of pus at the root of the tooth can cause throbbing pain. This often necessitates root canal treatment.
Is a loose crown causing my pain?
A loose crown can indeed cause pain and sensitivity. This is because the gaps between the crown and the tooth allow bacteria and food particles to enter, potentially leading to infection and inflammation. A loose crown should be addressed by a dentist as soon as possible.
Can I fix a loose crown at home?
While temporary measures like using dental cement (available at pharmacies) to temporarily re-secure a loose crown might seem appealing, it is strongly discouraged. These DIY methods are often ineffective and can even worsen the problem. A loose crown needs professional attention to ensure proper re-cementation and prevent further complications.
When should I see a dentist about crown pain?
You should consult your dentist immediately if you experience:
- Severe or persistent pain: Don't wait for the pain to subside on its own.
- Swelling or inflammation: This could indicate an infection.
- Increased sensitivity to hot or cold: This could be a sign of a problem with the tooth itself or the crown's fit.
- A loose crown: A loose crown increases the risk of infection.
- Difficulty chewing: This indicates an issue that needs professional evaluation.
Ignoring crown pain can lead to serious complications, including infection, tooth loss, and potentially more extensive and costly dental treatments. Early intervention is key to preserving your oral health. Schedule an appointment with your dentist to determine the cause of your pain and receive appropriate treatment.
