Experiencing tooth pain under a crown that comes and goes can be incredibly frustrating. This intermittent discomfort often indicates an underlying issue that needs attention, and ignoring it could lead to more serious problems down the line. Let's explore the potential causes, diagnostic approaches, and treatment options for this common dental concern.
What Causes Intermittent Tooth Pain Under a Crown?
The most common culprits behind this type of pain are:
-
Decay: Even with a crown in place, decay can occur beneath it, particularly if the tooth wasn't perfectly prepared before the crown was cemented. Bacteria can still find their way under the crown, leading to decay and subsequent inflammation and pain. This pain often intensifies when consuming hot or cold foods or drinks.
-
Pulpitis (Inflammation of the Tooth Pulp): Irritation or infection of the tooth's pulp (the soft tissue containing nerves and blood vessels) can cause throbbing pain that may come and go. This can be triggered by various factors, including trauma, decay, or a poorly fitting crown.
-
Periodontal Disease: Gum disease can affect the tissues supporting the tooth, even if a crown is present. Infection around the crown margin can lead to pain that's intermittent or constant.
-
Cracked Tooth: A pre-existing crack in the tooth that wasn't fully addressed before crowning can worsen over time, resulting in pain that comes and goes, especially with biting or chewing. The crown might mask the crack initially, but the underlying problem will still cause discomfort.
-
Sinus Infection: Pain originating in the sinuses can sometimes be felt in the upper teeth. This is less likely to be the cause if the pain is specifically isolated under the crown, but it's a possibility to consider.
-
Loose Crown: A crown that's become loose or shifted can create pressure points and cause pain that fluctuates.
How is Intermittent Tooth Pain Under a Crown Diagnosed?
Your dentist will conduct a thorough examination, including:
-
Visual Inspection: A careful examination of the crown and surrounding gum tissue to check for signs of decay, inflammation, or a loose crown.
-
X-rays: X-rays are essential to assess the tooth structure beneath the crown, detect any decay, cracks, or bone loss.
-
Percussion Test: The dentist taps gently on the affected tooth to check for sensitivity and pain.
-
Cold/Heat Test: Applying cold or hot stimuli to the tooth helps assess the health of the pulp.
Based on these findings, your dentist can accurately diagnose the problem and recommend appropriate treatment.
What are the Treatment Options for Tooth Pain Under a Crown?
Treatment depends on the underlying cause:
-
Decay: If decay is present, the dentist may need to remove the crown, clean out the decayed area, and potentially perform a root canal treatment before recementing the crown.
-
Pulpitis: A root canal is usually necessary to treat inflammation or infection of the tooth pulp. This involves removing the infected pulp, cleaning the canals, and filling them to prevent reinfection.
-
Periodontal Disease: Treatment may involve scaling and root planing to remove plaque and tartar from below the gum line, along with instructions on improving oral hygiene practices.
-
Cracked Tooth: Depending on the severity of the crack, the dentist might need to extract the tooth or attempt to repair it using procedures like a root canal and crown lengthening.
-
Loose Crown: The crown will need to be recemented, ensuring a proper fit.
-
Sinus Infection: In this case, your dentist might refer you to an ENT specialist for treatment of the sinus infection.
Can a Toothache Under a Crown Be Prevented?
Preventive measures play a key role:
-
Excellent Oral Hygiene: Maintaining meticulous oral hygiene—brushing twice daily, flossing regularly, and using an antimicrobial mouthwash—significantly reduces the risk of decay and gum disease.
-
Regular Dental Checkups: Regular visits to your dentist allow for early detection and treatment of any dental problems, even those hidden beneath crowns. This is crucial for preventing minor issues from escalating into more severe and painful conditions.
Does the Pain Always Indicate a Serious Problem?
While intermittent pain doesn't automatically mean a serious problem, it shouldn't be ignored. Early intervention is crucial to prevent the condition from worsening. Seeing your dentist as soon as possible is vital to determine the cause and receive timely treatment.
When Should I See a Dentist About Tooth Pain Under a Crown?
Don't delay seeking professional help if you experience persistent or worsening pain, sensitivity to temperature changes, swelling around the affected tooth, or a change in the crown's appearance (e.g., chipping, looseness). Prompt action prevents minor issues from becoming major dental emergencies.
By understanding the potential causes, diagnostic procedures, and treatment options, you can proactively address intermittent tooth pain under a crown and maintain optimal oral health. Remember, regular dental checkups and good oral hygiene practices are your best defense against future problems.
