Dental crowns are a common and effective solution for restoring damaged or decayed teeth. They are designed to be durable and long-lasting, but sometimes, they can fall out. Understanding the reasons why dental crowns can become dislodged can help you take preventive measures and seek appropriate care if it happens. In this blog, we will explore the common causes of dental crowns falling out and what you can do to prevent it.
Common Causes of Dental Crowns Falling Out
1. Cement Failure: The most common reason for a dental crown falling out is the failure of the dental cement that holds it in place. Over time, the cement can weaken due to factors such as:
- Saliva Breakdown: Saliva can gradually break down the dental cement, leading to a weakened bond between the crown and the tooth.
- Improper Application: If the cement was not applied correctly during the initial placement, the crown might not be securely attached.
2. Tooth Decay Under the Crown: Even though a crown protects the visible part of the tooth, the tooth underneath is still susceptible to decay. If decay occurs, it can weaken the structure that supports the crown, causing it to become loose and eventually fall out.
3. Physical Trauma or Impact: A blow to the face or mouth, such as during sports or an accident, can dislodge a dental crown. Additionally, habits like grinding or clenching teeth (bruxism) can exert excessive pressure on the crown, leading to its displacement.
4. Poor Fit: If the crown does not fit properly, it may not adhere securely to the tooth. An ill-fitting crown can result from:
- Inaccurate Impressions: Impressions taken during the preparation phase may not capture the tooth’s exact shape, leading to a poorly fitting crown.
- Changes in Tooth Structure: The tooth structure may change over time, affecting the fit of the crown.
5. Wear and Tear: Over time, the materials used for crowns can wear down. Crowns made from materials like porcelain or composite resin can become worn, chipped, or cracked, compromising their stability and leading to them falling out.
6. Chewing Hard or Sticky Foods: Eating hard or sticky foods can put undue stress on the crown, potentially dislodging it. Sticky foods like caramels or chewing gum can pull the crown off the tooth, while hard foods like nuts or ice can crack or break the crown.
7. Gum Disease: Gum disease can cause the gums to recede, exposing more of the tooth and weakening the support for the crown. This can lead to the crown becoming loose and eventually falling out.
What to Do If Your Crown Falls Out
If your dental crown falls out, it’s essential to take immediate steps to protect your tooth and seek professional dental care:
- Retrieve the Crown: Carefully retrieve the crown if possible. Rinse it with water and keep it safe, as your dentist might be able to reattach it.
- Protect the Tooth: If the tooth is sensitive or painful, you can use dental cement (available at most pharmacies) to temporarily reattach the crown or cover the exposed tooth with dental wax.
- Avoid Certain Foods: Avoid chewing on the affected side and stay away from hard, sticky, or crunchy foods until you can see your dentist.
- Contact Your Dentist: Schedule an appointment as soon as possible. They will examine the tooth and crown to determine the best course of action, which may involve reattaching the crown or creating a new one.
Preventing Dental Crowns from Falling Out
While it’s not always possible to prevent a crown from falling out, you can take several steps to reduce the risk:
- Maintain Good Oral Hygiene: Brush and floss regularly to prevent decay and gum disease.
- Avoid Hard and Sticky Foods: Be cautious with foods that can damage or dislodge your crown.
- Wear a Mouthguard: If you grind your teeth or play contact sports, wear a mouthguard to protect your crowns and teeth.
- Regular Dental Check-Ups: Visit your dentist regularly to ensure your crowns and overall oral health are in good condition.
Dental crowns can provide many years of service when properly cared for, but various factors can cause them to fall out. Understanding these causes and taking preventive measures can help maintain the longevity of your dental crowns. If a crown falls out, promptly addressing the issue with your dentist will protect and restore your oral health. Regular visits to Palm Dental Care, maintaining good oral hygiene, and adopting mindful eating habits are crucial for maintaining the security of your crowns.
