Metal porcelain crowns are a popular dental restoration option that provide both strength and aesthetics. If you have questions about these crowns, you're not alone. In this article, we will address the most frequently asked questions about metal porcelain crowns to help you make an informed decision about your dental health. Read on to find answers to your queries.
What Are Metal Porcelain Crowns?
Metal porcelain crowns, also known as porcelain-fused-to-metal (PFM) crowns, are dental restorations that combine the strength of a metal substructure with the natural appearance of porcelain. These crowns are commonly used to repair damaged teeth, strengthen weakened teeth, and improve aesthetics.
1. How are Metal Porcelain Crowns Made?
The process of creating metal porcelain crowns involves two main steps. First, your dentist will prepare the tooth by removing any damaged or decayed areas. Then, an impression of the tooth is taken, which is used to create a custom-made metal substructure. Finally, a layer of porcelain is fused to the metal substructure to create a natural-looking crown.
The metal substructure provides strength and stability, while the porcelain layer gives the crown its natural appearance. The color of the porcelain is carefully chosen to match the shade of your surrounding teeth, ensuring a seamless blend.
2. Are Metal Porcelain Crowns Durable?
Yes, metal porcelain crowns are known for their durability. The metal substructure offers excellent strength, making these crowns suitable for both front and back teeth. The porcelain layer adds an aesthetic touch and is resistant to staining. With proper care and regular dental check-ups, metal porcelain crowns can last for many years.
3. Can Metal Porcelain Crowns Cause Allergic Reactions?
In rare cases, some individuals may have an allergic reaction to the metals used in the substructure of metal porcelain crowns. Most commonly, nickel or other base metals can cause these reactions. It's important to inform your dentist if you have any known metal allergies, as alternative materials can be used to prevent allergic responses.
4. How Should I Care for Metal Porcelain Crowns?
Caring for metal porcelain crowns is similar to maintaining your natural teeth. Regular brushing, flossing, and rinsing with mouthwash are essential. Avoid chewing on hard objects, such as ice or pens, as this can damage the porcelain layer. Regular check-ups with your dentist will ensure the longevity and health of your metal porcelain crown.
Frequently Asked Questions (FAQ)
1. How long does it take to get a metal porcelain crown?
The process of getting a metal porcelain crown typically requires two dental appointments. During the first appointment, your tooth will be prepared and an impression will be taken. This impression is sent to a dental laboratory for crown fabrication. On the second appointment, the crown is fitted and permanently placed on your tooth.
2. Can metal porcelain crowns be used for front teeth?
Yes, metal porcelain crowns can be used for both front and back teeth. However, if aesthetics are a priority, all-porcelain crowns may be a better option for front teeth as they provide a more natural appearance.
3. Are metal porcelain crowns covered by insurance?
Many dental insurance plans partially cover the cost of metal porcelain crowns. It's best to consult with your insurance provider to understand your coverage and any out-of-pocket expenses you may have.
4. How long do metal porcelain crowns last?
Metal porcelain crowns can last anywhere from 10 to 15 years or even longer with proper care and maintenance. Regular dental check-ups and good oral hygiene practices are key to ensuring the longevity of your crown.
5. Can metal porcelain crowns be replaced if damaged?
If your metal porcelain crown becomes damaged, it can often be replaced. Your dentist will assess the condition of the crown and recommend the most suitable course of action to restore your dental health.
