Tooth Decay Under a Crown: Pictures, Causes, Symptoms, and Treatment
Dental crowns are designed to protect damaged teeth and restore their function and appearance. However, even with a crown in place, tooth decay can still occur underneath. This is a serious issue requiring prompt dental intervention. This article will explore the causes, symptoms, and treatment of tooth decay under a crown, supported by visual representations where appropriate (though I cannot directly display images). Imagine accompanying this text with illustrative photos easily found through a quick image search on Google, Bing or other search engines for visual reinforcement.
What are the signs of decay under a crown?
This is a crucial question because often, decay under a crown isn't immediately obvious. Early signs can be subtle and easily missed. These may include:
- Sensitivity to hot or cold: A sudden increase in sensitivity to temperature changes, even after the crown was initially placed, could indicate underlying decay.
- Discoloration: The area around the crown or the crown itself may exhibit darkening or discoloration.
- Pain: Pain, particularly when biting or chewing, is a significant warning sign. This pain might be persistent or intermittent.
- A loose crown: If the crown starts to feel loose or wobbly, it's possible underlying decay is weakening the tooth structure.
- Swelling or gum tenderness: Inflammation or tenderness in the gums surrounding the crown could suggest an infection related to decay under the crown.
While I cannot provide pictures directly, searching for "tooth decay under crown" on image search engines will provide numerous visual examples of these symptoms. Remember, if you experience any of these signs, schedule a visit with your dentist immediately.
What causes tooth decay under a crown?
Several factors can contribute to decay developing under a dental crown:
- Inadequate preparation before crown placement: If the tooth wasn't properly cleaned and prepared before the crown was cemented, bacteria could remain trapped underneath, leading to decay.
- Poor oral hygiene: Insufficient brushing and flossing, even with a crown, allows bacteria and plaque to accumulate, causing decay. Areas under the crown are particularly difficult to clean.
- Existing decay before crown placement: If there was pre-existing decay not completely addressed before the crown was fitted, it could progress beneath the crown.
- Leaking crown: Over time, a crown can develop a gap or leak, allowing bacteria and moisture to penetrate the space between the crown and the tooth.
- Cracked tooth: An existing crack in the underlying tooth, even after crown placement, can create a pathway for bacteria.
Understanding these causes emphasizes the importance of maintaining excellent oral hygiene and regular dental checkups.
How is tooth decay under a crown treated?
Treatment for decay under a crown depends on the severity of the damage:
- Minor decay: In cases of minimal decay, your dentist might remove the crown, clean the affected area, place a new filling, and then re-cement the crown.
- Moderate to severe decay: More extensive decay may require a root canal to remove the infected pulp (the soft tissue inside the tooth). After the root canal, the tooth may need a post and core buildup before the crown can be re-cemented or replaced.
- Extensive decay or tooth fracture: In severe cases where the tooth is extensively damaged or fractured, extraction may be necessary. A dental implant, bridge, or partial denture could be considered as replacement options.
Again, a visual examination by your dentist is essential to assess the extent of the damage and determine the most appropriate treatment. Do not attempt self-diagnosis or treatment.
Can you prevent tooth decay under a crown?
Yes, proactive measures can significantly reduce the risk of decay under a crown:
- Maintain meticulous oral hygiene: Brush twice daily with fluoride toothpaste and floss regularly, paying careful attention to the gum line around the crown.
- Regular dental checkups: Schedule routine dental checkups and cleanings to allow your dentist to detect any problems early on.
- Proper diet: Limit your intake of sugary and acidic foods and drinks, as these contribute to tooth decay.
By adopting these preventative measures, you can significantly extend the lifespan of your crown and maintain the health of your teeth.
How much does treating tooth decay under a crown cost?
The cost of treating decay under a crown varies depending on several factors, including the severity of the decay, the need for root canal treatment, and your location. The total cost will also depend upon the type of crown or the replacement tooth structure needed. It's best to contact your dentist directly for a personalized quote after a proper examination.
Remember, seeing your dentist regularly is crucial for preventing and detecting problems like tooth decay under a crown. Early intervention is key to preserving your oral health and avoiding more complex, costly treatments.
