Understanding Dental Crowns: Insights from Dr. Cindy Li
Hello, I’m Dr. Cindy Li from Excel Dental, located at 49 East Avenue South, Hamilton, Ontario. Today, I want to share some insights about dental crowns, a common yet often misunderstood dental procedure. Whether you’re considering a dental crown or just curious about the process, this article will provide you with a comprehensive understanding of what dental crowns are, the types available, the procedure involved, their benefits, common issues, and how to care for them.
What Are Dental Crowns? An Overview by Dr. Cindy Li
Dental crowns, often referred to as caps, are prosthetic devices that are cemented onto existing teeth or implants. Unlike removable devices such as dentures, which you can take out and clean daily, crowns are permanently fixed. They cover the entire visible portion of a tooth above the gum line, restoring its shape, size, strength, and appearance.
Crowns are typically used to protect a weak tooth from breaking, restore an already broken tooth, or cover and support a tooth with a large filling when there isn’t much tooth left. They can also be used to hold a dental bridge in place, cover misshaped or severely discolored teeth, and cover a dental implant.
The materials used for crowns can vary, including metals, porcelain, resin, and ceramics. Each material has its own advantages and is chosen based on the specific needs of the patient. For instance, metal crowns are known for their durability, while porcelain crowns offer a more natural appearance.
At Excel Dental, we ensure that each crown is custom-made to fit your tooth perfectly, providing both functional and aesthetic benefits. Our goal is to help you maintain a healthy, beautiful smile.
Types of Dental Crowns: Materials and Uses
There are several types of dental crowns, each made from different materials and suited for various uses. The most common types include metal crowns, porcelain-fused-to-metal (PFM) crowns, all-ceramic or all-porcelain crowns, and resin crowns.
Metal crowns are made from alloys that contain a high content of gold or platinum, or base-metal alloys like cobalt-chromium and nickel-chromium. These crowns are incredibly durable and can withstand biting and chewing forces well. They are often used for out-of-sight molars.
Porcelain-fused-to-metal crowns provide a stronger bond than regular porcelain because they are connected to a metal structure. They are more durable than all-porcelain crowns and can be color-matched to your adjacent teeth. However, the metal underlying the crown’s porcelain can sometimes show through as a dark line, especially at the gum line.
All-ceramic or all-porcelain crowns provide the best natural color match compared to any other crown type and may be more suitable for people with metal allergies. They are a good choice for front teeth. Resin crowns are less expensive than other crown types, but they wear down over time and are more prone to fractures.
Each type of crown has its own set of advantages and potential drawbacks. During your consultation at Excel Dental, we will discuss the best material for your specific needs, ensuring that your crown provides both functionality and aesthetics.
The Dental Crown Procedure: Step-by-Step Guide
The process of getting a dental crown typically requires two visits to the dentist. During the first visit, we will examine and prepare the tooth that needs the crown. This may involve taking X-rays to check the roots of the tooth and surrounding bone. If the tooth has extensive decay or there’s a risk of infection or injury to the tooth’s pulp, a root canal treatment may be performed first.
Next, we will numb the tooth and surrounding gum tissue before reshaping the tooth to make room for the crown. If a large area of the tooth is missing due to damage or decay, we may use a filling material to build up the tooth to support the crown. Once the tooth is reshaped, we will take an impression of the tooth and the surrounding teeth to ensure the crown will not affect your bite.
The impression is sent to a dental laboratory where the crown is manufactured. This process usually takes two to three weeks. In the meantime, we will place a temporary crown to protect the prepared tooth. The temporary crown is made of acrylic and is held in place using temporary cement.
During your second visit, we will remove the temporary crown and check the fit and color of the permanent crown. If everything is satisfactory, we will numb the tooth and permanently cement the crown in place. We will then make any necessary adjustments to ensure a comfortable bite.
Benefits of Dental Crowns: Health and Aesthetics
Dental crowns offer numerous benefits, both in terms of health and aesthetics. One of the primary health benefits is the protection they provide to damaged or weakened teeth. By covering the entire tooth, a crown can prevent further decay and damage, reducing the risk of tooth loss.
Crowns also restore the functionality of your teeth. If you have a tooth that is cracked or severely worn down, a crown can restore its shape and size, allowing you to chew and speak properly. This can significantly improve your quality of life, making everyday activities more comfortable and enjoyable.
From an aesthetic perspective, dental crowns can greatly enhance the appearance of your smile. They can be color-matched to your natural teeth, ensuring a seamless and natural look. This is particularly beneficial for front teeth, where appearance is especially important. Crowns can also cover discolored or misshapen teeth, giving you a more uniform and attractive smile.
Additionally, dental crowns can provide long-lasting results. With proper care, crowns can last for many years, making them a cost-effective solution for dental restoration. At Excel Dental, we use high-quality materials and advanced techniques to ensure that your crowns are durable and aesthetically pleasing.
Common Issues and Solutions with Dental Crowns
While dental crowns are generally very effective, there are some common issues that patients may experience. One of the most common problems is sensitivity or discomfort after the crown is placed. This is usually temporary and can be managed with over-the-counter pain relievers. If the sensitivity persists, it may indicate that the crown is too high and needs to be adjusted.
Another issue that can occur is the crown becoming loose or falling off. This can happen if the cement that holds the crown in place washes out or if there is decay under the crown. If your crown becomes loose or falls off, it’s important to contact us immediately so we can re-cement it or provide a new crown if necessary.
Crowns can also chip or crack, especially if they are made of porcelain. Small chips can often be repaired with composite resin, but larger cracks may require a new crown. To minimize the risk of damage, avoid chewing on hard objects like ice or pens, and wear a mouthguard if you grind your teeth at night.
In rare cases, patients may experience an allergic reaction to the materials used in the crown. If you have a known allergy to certain metals, be sure to inform us during your consultation so we can choose a suitable material for your crown. At Excel Dental, we are committed to addressing any issues promptly and effectively to ensure your comfort and satisfaction.
Caring for Your Dental Crowns: Expert Tips from Dr. Li
Proper care is essential to ensure the longevity and effectiveness of your dental crowns. One of the most important aspects of crown care is maintaining good oral hygiene. This includes brushing your teeth at least twice a day and flossing daily to remove plaque and prevent decay around the crown.
It’s also important to avoid habits that can damage your crowns, such as chewing on hard objects, grinding your teeth, or using your teeth as tools. If you have a habit of grinding your teeth, we may recommend a nightguard to protect your crowns and natural teeth from excessive wear.
Regular dental check-ups are crucial for monitoring the condition of your crowns and overall oral health. During these visits, we will check the fit and integrity of your crowns and address any potential issues before they become serious problems. Professional cleanings can also help maintain the health of your gums and the area around the crown.
Lastly, be mindful of your diet. While crowns are durable, they can still be damaged by certain foods. Avoid sticky or hard foods that can dislodge or crack your crown. Eating a balanced diet rich in vitamins and minerals can also support your overall oral health. At Excel Dental, we are here to provide guidance and support to help you care for your dental crowns effectively.
