Experiencing intermittent tooth pain under a crown can be incredibly frustrating. That nagging ache that comes and goes can leave you wondering what's happening beneath the surface of your seemingly perfect restoration. This comprehensive guide will delve into the potential causes of this problem, explore effective treatment options, and offer valuable preventative measures to help you maintain a healthy smile.
What Causes Tooth Pain Under a Crown That Comes and Goes?
Several factors can contribute to intermittent pain under a dental crown. The pain often isn't constant because the underlying issue might not always be actively irritating the nerve. Here are some key culprits:
- Decay: Even with a crown in place, decay can occur beneath the restoration, particularly if there was pre-existing decay that wasn't fully addressed before the crown was placed. Bacteria can still find their way under the crown's margin, leading to decay and subsequent pain.
- Inflammation or Irritation of the Pulp (Nerve): This could stem from various sources like bacterial infection, a poorly fitting crown, or trauma to the tooth. Inflammation can cause intermittent pain as the pressure and irritation fluctuate.
- Cracked Tooth: A pre-existing crack in the tooth, often undetected before the crown was fitted, can become aggravated over time. This can cause pain that is intermittent and related to chewing or temperature changes.
- Gum Disease (Periodontitis): Gum disease can lead to inflammation and infection around the tooth, which can then cause pain that radiates to the area under the crown. This pain might be more noticeable at certain times of the day or after eating.
- Sinus Infection: Pain originating from a sinus infection can sometimes be mistaken for tooth pain, especially in the upper teeth. This is because the roots of upper molars are close to the sinuses.
How is Tooth Pain Under a Crown Diagnosed?
Diagnosing the exact cause of your pain requires a thorough examination by your dentist. They will likely perform the following:
- Visual Examination: A careful visual inspection of the crown and surrounding gum tissue.
- X-rays: X-rays are crucial to identify decay, cracks, or other underlying structural issues in the tooth.
- Percussion Test: The dentist will gently tap on the tooth to assess for sensitivity or pain.
- Temperature Sensitivity Test: The tooth will be tested with hot and cold stimuli to determine the level of sensitivity.
Based on the findings, your dentist can determine the appropriate course of action.
What Treatments Are Available for Tooth Pain Under a Crown?
Treatment depends entirely on the underlying cause. Possible options include:
- Root Canal Treatment: If decay or inflammation of the pulp is the culprit, a root canal might be necessary to remove the infected pulp and seal the tooth.
- Crown Replacement or Adjustment: If the crown is poorly fitted, causing irritation, it may need to be replaced or adjusted to improve its fit.
- Antibiotics: If a bacterial infection is present, antibiotics may be prescribed to combat the infection.
- Gum Disease Treatment: If gum disease is the underlying issue, treatment such as scaling and root planing will be necessary.
Can Tooth Pain Under a Crown Be Prevented?
While some issues are unavoidable, you can take steps to reduce your risk of experiencing tooth pain under a crown:
- Maintain Excellent Oral Hygiene: This includes regular brushing and flossing, as well as using an antiseptic mouthwash as directed by your dentist.
- Regular Dental Checkups: Regular visits to your dentist for checkups and cleanings are essential for early detection and treatment of any potential problems.
- Avoid Hard Foods: Refrain from biting down on excessively hard foods that could put pressure on the crown and the underlying tooth structure.
- Choose a Reputable Dentist: Selecting an experienced and qualified dentist is crucial for ensuring proper crown placement and overall oral health.
What if the Pain is Severe?
If you experience severe or persistent pain under your crown, contact your dentist immediately. Delaying treatment can worsen the underlying problem and potentially lead to more significant complications.
Does a cracked tooth under a crown always need to be extracted?
Not necessarily. Whether extraction is needed for a cracked tooth under a crown depends on the severity and location of the crack. In some cases, root canal therapy and crown repair or replacement may be sufficient. However, if the crack is extensive and compromises the tooth's structural integrity, extraction might be the only viable option. Your dentist will conduct a thorough examination to determine the best course of action.
How long does it take for tooth pain under a crown to go away?
The duration of tooth pain under a crown varies greatly depending on the underlying cause and the treatment received. For minor irritations, the pain might subside quickly after a simple adjustment. However, more complex issues, such as a root canal, might take several days or weeks for complete resolution of the pain.
