Tooth Decay Under a Crown: Pictures, Causes, and Treatment
Dental crowns are designed to protect damaged teeth and restore their function and appearance. However, despite their protective nature, decay can still occur underneath a crown. This article will explore the causes, detection, and treatment of tooth decay under a crown, along with addressing common questions people have on this topic. We'll even touch upon preventative measures to help you maintain optimal oral health.
What does tooth decay under a crown look like?
Unfortunately, you can't see tooth decay under a crown with the naked eye. The crown itself obscures the affected area. This makes regular dental check-ups crucial. While there aren't readily available "pictures" showing decay under a crown, X-rays are the primary diagnostic tool used by dentists to detect this issue. X-rays will reveal any decay present beneath the crown’s surface, showing radiolucent areas (dark spots) indicative of decay. Your dentist will be able to interpret these images and inform you of the extent of the problem.
Why does tooth decay happen under a crown?
Several factors can contribute to decay developing beneath a dental crown:
- Inadequate preparation of the tooth before crown placement: If the tooth wasn't properly cleaned and prepared before the crown was cemented, bacteria could remain trapped under the crown, leading to decay.
- Poor oral hygiene: Insufficient brushing and flossing allow plaque and bacteria to accumulate, even under the crown's margins. This buildup creates an acidic environment conducive to decay.
- Leaking crown margins: Over time, the cement sealing the crown to the tooth can degrade or crack, creating gaps that allow bacteria and food particles to penetrate underneath.
- Pre-existing decay: If decay was already present on the tooth before crown placement, it might not have been completely removed, leading to its progression under the crown.
- Type of crown material: While the material itself doesn't directly cause decay, some materials might be more susceptible to developing leakage than others.
- Dietary habits: A diet high in sugar and refined carbohydrates creates an ideal environment for bacterial growth and acid production, increasing the risk of decay.
How is tooth decay under a crown diagnosed?
As mentioned earlier, visual inspection alone isn't sufficient. The dentist will rely on several methods:
- Dental X-rays: These are the most effective diagnostic tool to detect decay hidden under the crown.
- Transillumination: A special light can be used to illuminate the tooth, sometimes helping to detect subtle changes in tooth structure suggestive of decay.
- Clinical examination: The dentist will check for any signs of leakage, discoloration, or sensitivity around the crown.
What are the symptoms of tooth decay under a crown?
Often, there are no noticeable symptoms in the early stages. However, as the decay progresses, you might experience:
- Sensitivity to hot or cold: This is a common sign of decay, regardless of whether it's under a crown or not.
- Pain when biting or chewing: This indicates a more advanced stage of decay.
- Discoloration around the crown: While not directly visible under the crown, subtle discoloration might appear around its edges.
- Bad breath or a foul taste in your mouth: This can be an indication of bacterial infection.
How is tooth decay under a crown treated?
Treatment will depend on the severity of the decay:
- Minor decay: The dentist may remove the crown, clean the decay, and re-cement the crown.
- Moderate to severe decay: The decay may necessitate a root canal treatment to remove the infected pulp before the crown is replaced or repaired. In some cases, the tooth may be too severely damaged to save, requiring extraction.
Can I prevent tooth decay under a crown?
Yes! Diligent oral hygiene and regular dental check-ups are crucial for preventing decay.
- Maintain excellent oral hygiene: Brush twice a day with fluoride toothpaste, floss daily, and use an antimicrobial mouthwash.
- Regular dental check-ups: Visit your dentist for regular check-ups and cleanings at least twice a year, or as recommended by your dentist. This allows for early detection and treatment of any issues.
- Healthy diet: Limit sugary drinks and snacks.
Remember, early detection is key to successful treatment. Don't hesitate to contact your dentist if you experience any symptoms or concerns about your dental crown. Regular checkups and proactive oral hygiene are your best defense against decay, even under a crown.
