Dealing with Cracked Porcelain Crowns: Causes and Solutions - Dentistry

More Info

---

Dealing with cracked porcelain crowns can be a frustrating experience, especially if it happens repeatedly. Porcelain crowns are designed to be durable and aesthetically pleasing, but they can still crack or break under certain conditions. Here are some potential causes and solutions to consider:

Causes of Cracked Porcelain Crowns
1. Bruxism (Teeth Grinding): One of the most common reasons for cracked crowns is bruxism, which is the involuntary grinding or clenching of teeth, often occurring during sleep. This excessive pressure can lead to fractures in porcelain crowns, especially if they are not reinforced or if the underlying tooth structure is compromised.

2. Improper Fit: If the crown does not fit properly, it can create uneven pressure on the tooth, leading to cracks. A poorly fitted crown may also cause discomfort and additional wear on adjacent teeth.

3. Material Quality: The quality of the porcelain used in the crown can also affect its durability. Lower-quality materials may be more prone to chipping or cracking.

4. Underlying Tooth Issues: If the tooth beneath the crown has structural issues, such as decay or fractures, it can compromise the integrity of the crown.
5. Excessive Force: Activities that involve biting down on hard objects (like ice or hard candies) can exert excessive force on crowns, leading to fractures.


Solutions for Cracked Porcelain Crowns
1. Consult Your Dentist: The first step is to schedule an appointment with your dentist. They can assess the damage and determine whether the crown can be repaired or if it needs to be replaced.
2. Evaluate for Bruxism: If you suspect that grinding your teeth at night is the cause, discuss this with your dentist. They may recommend a night guard, which is a custom-fitted appliance that you wear while sleeping to protect your teeth and crowns from grinding forces.

3. Consider Material Options: If you have had multiple issues with porcelain crowns, you might want to discuss alternative materials with your dentist. Zirconia crowns, for example, are known for their strength and may be a better option if you have a history of cracking.

4. Proper Fit and Adjustment: If your crown is not fitting well, your dentist can make adjustments to ensure a better fit. This may involve reshaping the crown or the underlying tooth structure.

5. Avoid Hard Foods: To prevent further damage, try to avoid biting down on hard foods or objects. Being mindful of your eating habits can help prolong the life of your crowns.

6. Regular Dental Check-ups: Regular visits to your dentist can help catch any issues early on. They can monitor the condition of your crowns and the health of your teeth, allowing for timely interventions if problems arise.

7. Consider a Different Type of Crown: If you continue to experience issues with porcelain crowns, it may be worth discussing other types of crowns with your dentist. Some materials may offer better durability based on your specific dental needs.


Conclusion
Cracked porcelain crowns can be a sign of underlying issues that need to be addressed. By consulting with your dentist and considering factors such as bruxism, fit, and material quality, you can find effective solutions to prevent future damage. Remember, maintaining good oral hygiene and regular dental check-ups are key to ensuring the longevity of your dental restorations. If you suspect that grinding your teeth is a contributing factor, addressing this issue promptly can save you from further complications.
