Why Does My Tooth with a Crown Hurt?
A crown is designed to protect a damaged tooth, restoring its function and appearance. However, sometimes, even a crowned tooth can cause pain. This can be frustrating and worrying, but understanding the potential causes can help you address the issue effectively. This article explores the various reasons why a tooth with a crown might hurt and what you can do about it.
What are the common reasons for pain under a crown?
This is a frequent question asked by many experiencing this issue. Several factors can lead to pain beneath a dental crown, often stemming from problems with the underlying tooth structure or the crown itself. Let's explore some of the most common culprits:
-
Inflammation or Irritation of the Pulp (Root Canal Issues): Even with a crown, the underlying tooth structure can still experience issues. Pulpitis, or inflammation of the pulp (the soft tissue inside the tooth containing nerves and blood vessels), is a common cause. This can be due to existing decay that wasn't fully addressed before the crown was placed, a crack or fracture in the tooth that developed later, or bacterial infection. The pain can range from mild sensitivity to sharp, throbbing agony. If the inflammation is severe, a root canal may be necessary.
-
Cracked or Fractured Tooth: A crack or fracture in the tooth, either present before the crown was placed or developing afterward, can cause significant pain. The crown might mask the fracture initially, but pressure or biting can exacerbate the pain. This requires careful examination and may necessitate further treatment, possibly even extraction in severe cases.
-
Gum Irritation or Infection (Periapical Abscess): Gum irritation around the crowned tooth can cause pain and discomfort. This can arise from poor oral hygiene, leading to gum disease (gingivitis or periodontitis). In more serious cases, a periapical abscess—a pus-filled pocket at the tip of the root—can develop, resulting in severe pain, swelling, and even fever.
-
Crown-Related Problems: The crown itself can sometimes be the source of the pain. A poorly fitted crown can irritate the gum tissue, leading to discomfort. A loose or fractured crown can also cause pain and sensitivity. In such cases, the crown may need adjustment, refitting, or replacement.
-
Sinus Infection: Upper teeth are in close proximity to the sinuses. A sinus infection can sometimes cause referred pain that feels like it originates from a tooth, even one with a crown.
What should I do if my crowned tooth hurts?
If you are experiencing pain in a tooth with a crown, it's crucial to seek professional dental care immediately. Don't delay treatment, as ignoring the pain can lead to more significant complications. Your dentist will be able to properly diagnose the cause of your pain and recommend the appropriate treatment.
How is the pain diagnosed?
Diagnosis typically involves a comprehensive examination, including X-rays to assess the underlying tooth structure and identify any fractures, abscesses, or other issues. Your dentist may also perform a percussion test (tapping on the tooth) and palpation (feeling around the tooth and gum) to assess sensitivity and detect any inflammation.
How is the pain treated?
Treatment depends on the underlying cause. Options range from simple adjustments to the crown to more complex procedures like root canals, extractions, or the replacement of the crown. In cases of gum disease, improved oral hygiene and professional cleaning may be sufficient.
Can I prevent pain in my crowned tooth?
Maintaining excellent oral hygiene is key to preventing pain in a crowned tooth. This includes brushing and flossing meticulously, using an antiseptic mouthwash, and visiting your dentist regularly for checkups and cleanings. Avoid biting down on hard objects or using your teeth to open packages to minimize the risk of crown damage or fractures in the underlying tooth. Following your dentist’s recommendations post-crown placement is also vital for long-term success.
Remember, seeking timely professional dental care is vital for effective management of pain in a crowned tooth. Don't hesitate to contact your dentist if you experience any discomfort. Early intervention often leads to simpler and less invasive treatment options.
