Experiencing tooth pain under a crown that comes and goes can be incredibly frustrating. This intermittent pain often signals an underlying dental problem that requires professional attention. Ignoring it can lead to more serious complications, so understanding the potential causes and seeking timely treatment is crucial.
What Causes Tooth Pain Under a Crown That Comes and Goes?
Several factors can contribute to this type of pain. The most common culprits include:
-
Decay: Despite the crown protecting the visible portion of your tooth, decay can still occur underneath, particularly if there was existing decay before the crown was placed or if the crown doesn't fit perfectly, allowing bacteria to penetrate. This is a significant reason why excellent oral hygiene is critical, even after crown placement.
-
Pulpitis (Inflammation of the Pulp): The pulp is the soft tissue inside your tooth containing nerves and blood vessels. Inflammation of the pulp can cause intermittent pain, often worsening with temperature changes (hot or cold). This can be a result of decay, trauma, or a poorly fitting crown.
-
Cracked Tooth: A crack in the tooth structure beneath the crown can cause pain that fluctuates depending on biting pressure and other factors. Sometimes, the crack may not be visible on an X-ray, making diagnosis challenging.
-
Periodontal Disease (Gum Disease): Gum disease can lead to inflammation and infection around the tooth, which can manifest as pain that extends to the area under the crown.
-
Sinus Infection: In some cases, pain originating from a sinus infection might be mistakenly attributed to a dental problem. The proximity of the sinuses to the upper teeth means that pain can sometimes be referred.
-
Abscess: A pocket of pus caused by a bacterial infection at the root of the tooth can cause severe, throbbing pain that comes and goes. This usually requires urgent treatment.
What Should I Do if I Have Tooth Pain Under a Crown?
If you're experiencing tooth pain under a crown, even if it's intermittent, don't delay seeking professional dental care. Your dentist is best equipped to diagnose the underlying cause and recommend appropriate treatment. Delaying treatment can lead to more extensive damage and more complex—and costly—procedures in the future.
How is Tooth Pain Under a Crown Diagnosed?
Your dentist will likely perform a thorough examination, including:
- Visual Inspection: A careful examination of the crown and surrounding gum tissue.
- X-rays: To assess the tooth structure underneath the crown and identify any decay, cracks, or abscesses.
- Percussion Test: Gently tapping on the tooth to check for sensitivity.
- Cold/Heat Test: Applying cold or hot stimuli to determine the level of pulp inflammation.
How is Tooth Pain Under a Crown Treated?
Treatment depends on the underlying cause:
- Decay: May involve removing the decay, placing a filling, and potentially replacing the crown.
- Pulpitis: Might require a root canal to remove the inflamed pulp and prevent further infection.
- Cracked Tooth: May necessitate a root canal, a crown replacement, or in severe cases, tooth extraction.
- Periodontal Disease: Requires periodontal treatment to address the gum infection.
- Abscess: Often involves drainage of the abscess and antibiotics to combat infection.
Can I Prevent Tooth Pain Under a Crown?
While you can't entirely eliminate the risk, proactive measures can significantly reduce the chances of experiencing pain under a crown:
- Maintain Excellent Oral Hygiene: Brush and floss meticulously twice a day.
- Regular Dental Checkups: Schedule regular checkups and cleanings to catch any problems early.
- Avoid Hard Foods: Minimize chewing extremely hard foods that might damage the crown or underlying tooth structure.
- Report Any Unusual Symptoms Immediately: Don't wait for the pain to become unbearable; contact your dentist at the first sign of any discomfort.
How Long Does Tooth Pain Under a Crown Last?
The duration of pain varies depending on the cause and treatment. If left untreated, the pain can persist for a prolonged period and worsen. With prompt professional intervention, the pain can often be resolved relatively quickly.
Is Tooth Pain Under a Crown an Emergency?
While not always an immediate emergency, persistent or severe pain under a crown requires prompt attention. If the pain is intense, accompanied by swelling, or interferes with your ability to eat or sleep, seek immediate dental care.
