Dental crowns are designed to protect a damaged or weakened tooth, restoring its function and appearance. However, a common question arises: can you still get a cavity underneath or around a crown? The short answer is yes, but it's less common than decay on a natural tooth. Understanding why this happens, and how to prevent it, is crucial for maintaining excellent oral health.
Why Can Cavities Develop Under or Around Crowns?
While crowns significantly reduce the risk of cavities, they aren't foolproof. Decay can still occur due to several factors:
-
Poor Oral Hygiene: Failing to maintain diligent brushing and flossing allows plaque and bacteria to accumulate, even around the crown's margins. This buildup can lead to decay at the gum line or under the crown's edges, especially if the crown isn't perfectly fitted.
-
Inadequate Crown Placement: If the crown isn't properly cemented or if there's a gap between the crown and the tooth, bacteria can easily penetrate and cause decay. This is why it's essential to see a skilled and experienced dentist for crown placement.
-
Existing Decay Before Crown Placement: If decay wasn't completely removed before the crown was installed, it can continue to progress underneath, leading to further problems.
-
Root Decay: Even with a crown, the roots of the tooth can still be susceptible to decay, particularly in individuals with gum disease or receding gums.
-
Sugary Drinks and Snacks: Frequent consumption of sugary and acidic foods and drinks weakens tooth enamel, increasing the risk of decay even under a crown.
How Can I Prevent Cavities Under or Around a Crown?
Prevention is key to maintaining the longevity and effectiveness of your dental crown. Here's how to minimize the risk of developing cavities:
-
Maintain Excellent Oral Hygiene: Brush twice daily with fluoride toothpaste, floss daily, and use an antimicrobial mouthwash as recommended by your dentist. Pay close attention to the area around your crown, ensuring you thoroughly clean the gum line.
-
Regular Dental Checkups and Cleanings: Regular visits to your dentist allow for early detection of any potential problems. Professional cleanings remove plaque and tartar buildup that you might miss at home. X-rays can also detect decay that's not visible to the naked eye.
-
Proper Diet: Limit your intake of sugary and acidic foods and drinks. Rinse your mouth with water after consuming these items.
-
Avoid Harmful Habits: Refrain from habits like grinding your teeth or clenching your jaw, as these can put extra stress on your crown and potentially lead to cracks or gaps where bacteria can enter.
What Happens If I Get a Cavity Under My Crown?
If a cavity develops under your crown, your dentist will need to remove the crown to access and treat the decay. This may involve filling the cavity, performing a root canal if the infection has reached the pulp, or in severe cases, extracting the tooth. It's important to address the issue promptly to prevent further complications.
Can You Get a Cavity On a Crown?
While less likely than decay under a crown, it's theoretically possible for decay to develop on the crown's surface if the material is porous or if there is significant plaque buildup that isn’t removed during regular cleanings. However, this is rare with modern dental crowns.
How Often Should I See My Dentist for Checkups After Getting a Crown?
The frequency of dental checkups after receiving a crown depends on your individual oral health needs and your dentist's recommendations. However, most dentists recommend at least once or twice a year for checkups and professional cleanings to ensure the long-term health and integrity of your crown.
By following these preventive measures and maintaining regular dental visits, you can significantly reduce the risk of cavities developing under or around your dental crowns, ensuring the long-term success of your restorative treatment. Remember, consistent oral hygiene and regular professional care are essential for maintaining a healthy smile.
