Dental crowns are one of the most common restorative dental procedures, offering a reliable solution to restore damaged or weakened teeth. Whether you've experienced tooth decay, a fracture, or wear from grinding, a dental crowns can help you regain the full function and appearance of your tooth. In this blog, we will explore what dental crowns are, when they are necessary, how they are applied, and what you can expect during the process.
What Is a Dental Crown?
A dental crown is a cap that fits over a damaged or weakened tooth to restore its shape, size, strength, and appearance. The crown is designed to cover the tooth entirely, essentially making it “new” again. Crowns are made from various materials, including metal, porcelain, and ceramic, and are customized to match the natural color of your surrounding teeth for a seamless finish.
Crowns are used in both restorative and cosmetic dentistry. They can help preserve the function of a tooth that has been weakened due to decay or damage and can also be used to improve the aesthetics of a tooth that is misshapen or discolored.
Types of Dental Crowns
Dental crowns come in several different materials, each with its own benefits. The choice of material often depends on the location of the tooth, the level of damage, your budget, and your personal preferences.
1. Porcelain Crowns
Porcelain crowns are often chosen for their aesthetic qualities. These crowns are made to look and feel like natural teeth, making them a popular choice for visible teeth, such as the front teeth. Porcelain crowns are highly durable and resistant to staining, though they may not be as strong as metal crowns, especially in the back teeth where heavy chewing forces occur.
2. Porcelain-Fused-to-Metal Crowns
These crowns combine the strength of metal with the natural appearance of porcelain. The metal structure provides a solid base, while the porcelain overlay mimics the look of natural enamel. This type of crown is commonly used for teeth that require additional strength, such as molars, but still want a more natural appearance compared to full metal crowns.
3. Metal Crowns
Metal crowns are typically made from alloys such as gold, platinum, or other non-corrosive metals. They are highly durable and can withstand the pressure from chewing, making them ideal for back teeth. However, the main downside is that they are not as aesthetically pleasing since they don’t resemble natural teeth.
4. Zirconia Crowns
Zirconia is a relatively new material that offers strength and durability while closely mimicking the appearance of natural teeth. These crowns are made from a strong, biocompatible material that is ideal for both front and back teeth. Zirconia crowns are often considered an excellent all-around option for durability and appearance.
5. Resin Crowns
Resin crowns are typically less expensive than porcelain or metal crowns, but they also tend to wear down faster. Resin is a good option for those looking for a budget-friendly solution, but it's not as durable as other types of crowns, especially in high-pressure areas like the back teeth.
Why Are Dental Crowns Needed?
Dental crowns can be recommended for a variety of reasons. They are commonly used in the following situations:
1. To Protect a Weak Tooth
Teeth that have been weakened by decay, large fillings, or fractures may be at risk of breaking. A crown can provide additional strength to prevent the tooth from cracking or falling apart, helping preserve the tooth’s function.
2. To Restore a Broken or Worn-Down Tooth
If a tooth has been chipped, cracked, or severely worn down (often due to grinding or clenching), a crown can restore its appearance and function. The crown will cover the damaged tooth and help protect it from further damage.
3. To Hold a Dental Bridge in Place
When a tooth is missing and a dental bridge is used to fill the gap, crowns are placed on the adjacent teeth to anchor the bridge securely in place. The crowns on the adjacent teeth provide the necessary support to maintain the bridge's stability.
4. To Cover a Dental Implant
Dental implants are often crowned with a tooth-like cap once the implant has been placed and the bone has integrated with the implant. The crown serves as the replacement tooth, providing both function and aesthetics.
5. To Improve the Appearance of a Tooth
For teeth that are discolored, misshapen, or unusually large or small, a crown can be used to improve the appearance of the tooth. Porcelain or ceramic crowns are ideal in these cases because they can be customized to match the surrounding teeth.
6. After Root Canal Therapy
If a tooth has undergone root canal treatment, it can become more brittle and susceptible to fracture. A crown is often placed over the tooth to protect it and restore its strength and function.
The Process of Getting a Dental Crown
The process of getting a dental crown usually takes two visits to the dentist. Here's what you can expect during each appointment:
First Visit: Preparation and Impression
-
Examination and X-rays: Your dentist will begin by examining the tooth and taking X-rays to ensure there is no underlying infection or damage to the tooth’s roots.
-
Tooth Preparation: If the tooth is severely damaged, your dentist may need to reshape it to ensure the crown fits properly. In some cases, if a significant portion of the tooth is missing, a filling material may be added to build up the tooth before placing the crown.
-
Impressions: Once the tooth is prepared, your dentist will take an impression of the tooth and the surrounding area. This mold is sent to a dental lab where your custom crown will be created. If needed, a temporary crown will be placed to protect the tooth while the permanent one is made.
Second Visit: Crown Placement
-
Fitting: Once the custom crown is ready, your dentist will remove the temporary crown and fit the new one over your tooth. The dentist will check for proper fit, bite alignment, and comfort.
-
Cementing the Crown: After ensuring the crown fits perfectly, it will be permanently cemented into place. If you have a porcelain crown, your dentist will also make sure it matches the color of your surrounding teeth for a seamless result.
-
Final Adjustments: Any necessary adjustments will be made, and the procedure will be completed.
Caring for Your Dental Crown
Once your crown is in place, it's important to maintain good oral hygiene to ensure its longevity. Here are a few tips to care for your new dental crown:
-
Brush and Floss Regularly: Brush your teeth at least twice a day and floss daily to remove plaque buildup around the crown. Be careful when flossing to avoid dislodging the crown.
-
Avoid Hard Foods: While crowns are durable, avoid chewing on hard objects like ice or pens to prevent damaging the crown or your natural teeth.
-
Visit Your Dentist Regularly: Keep up with regular dental checkups to monitor the health of your crown and surrounding teeth.
-
Be Mindful of Teeth Grinding: If you grind your teeth at night, consider wearing a nightguard to protect your crown and natural teeth from excessive wear.
Benefits of Dental Crowns
- Durability: Dental crowns are long-lasting and can endure years of daily use with proper care.
- Restoration of Function: Crowns restore the full function of damaged teeth, allowing you to chew and speak normally.
- Aesthetic Improvement: Porcelain and ceramic crowns provide a natural-looking solution to damaged or discolored teeth.
- Protection: Crowns provide a protective barrier for weakened teeth, helping prevent further damage or fractures.
