How Does A Crown Work? (Dental Work Procedure)

Are you curious about how a crown works and what the dental crown procedure entails? In this article, we will explore the ins and outs of dental crowns, including their purpose, materials used, and the step-by-step process involved in getting one.

A dental crown is a tooth-shaped cap that is used to restore weak, broken, or decayed teeth. It provides strength and protection by fitting over the entire tooth. Crowns can be made from various materials, such as resin, metal, and porcelain, each offering different benefits and aesthetics.

During the dental crown procedure, your dentist will prepare the tooth by removing a small amount of enamel to make room for the crown. An impression will be taken, and a temporary crown may be placed. The impression will be sent to a lab to create a custom crown, or in the case of same-day crowns, the crown will be created in-office using CAD/CAM technology. On your final visit, the permanent crown will be cemented in place.

Caring for dental crowns involves regular oral hygiene practices, such as brushing your teeth with fluoride toothpaste, flossing, and visiting your dentist for check-ups. It’s essential to maintain good dental hygiene to ensure the longevity of your crown.

Now that you have a brief overview of how a crown works and the dental crown process, let’s delve into more detailed information about the types of dental crowns, the materials used, the benefits, risks, alternatives, and the importance of regular dental check-ups for crown maintenance.

Key Takeaways:

• Dental crowns are tooth-shaped caps used to restore weak, broken, or decayed teeth.
• They can be made from materials like resin, metal, and porcelain.

Types of Dental Crowns

When it comes to dental crowns, there are several types to choose from, each with its own unique characteristics and advantages. Understanding the different options can help you make an informed decision about which type of crown is best for your dental needs.

Metal Crowns

Metal crowns, made from materials such as gold, palladium, nickel, or chromium, are known for their durability and strength. They can withstand biting and chewing forces and are less likely to chip or break compared to other types of crowns. However, metal crowns have a metallic appearance and may not be the most aesthetically pleasing option.

Porcelain-Fused-to-Metal (PFM) Crowns

Porcelain-fused-to-metal (PFM) crowns provide a balance between natural aesthetics and strength. These crowns combine a metal base for strength with a porcelain coating for a natural tooth-like appearance. PFM crowns are a popular choice for individuals who want a crown that looks natural but also offers durability and strength.

Pressed Ceramic Crowns

Pressed ceramic crowns are known for their natural appearance and ability to mimic the translucency of natural tooth enamel. These crowns have a hard inner core and are then layered with porcelain to achieve a lifelike appearance. Pressed ceramic crowns are a suitable choice for individuals who prioritize aesthetics and want a crown that closely resembles their natural teeth.

All-Ceramic or Porcelain Crowns

All-ceramic or porcelain crowns are the go-to option for those looking for the most natural-looking crown. These crowns offer excellent aesthetics, as they can closely mimic the color, shape, and translucency of natural teeth. Additionally, all-ceramic crowns are an ideal choice for individuals with metal allergies, as they do not contain any metal components.

Ultimately, the type of dental crown that is right for you will depend on factors such as your individual dental needs, aesthetic preferences, and budget. Consulting with your dentist can help you determine the best crown option to restore the function and appearance of your teeth.

Dental Crown Procedure

When it comes to dental crown procedures, there are two main methods: traditional crowns and CEREC crowns. Let’s take a look at the step-by-step process for each:

Traditional Crowns

1. The first step in the traditional crown procedure is preparing the tooth. The dentist will remove a small amount of enamel to create space for the crown.
2. Next, an impression of the tooth is taken using a putty-like material. This impression will be used to create a custom crown that fits perfectly over the prepared tooth.
3. While the permanent crown is being made in a dental laboratory, a temporary crown is placed to protect the prepared tooth.
4. During the final visit, the temporary crown is removed, and the permanent crown is cemented in place after ensuring a proper fit and alignment.

Traditional crowns typically require two or three visits to the dentist, with a waiting period between appointments for the crown to be fabricated.

CEREC Crowns

CEREC crowns, on the other hand, offer a same-day crown placement option due to the use of advanced CAD/CAM technology. Here’s how the process works:

1. The tooth is prepared as with traditional crowns, removing a small amount of enamel to make room for the crown.
2. An optical impression of the tooth is taken using a 3D digital scanner, eliminating the need for messy putty impressions.
3. The dentist uses computer-aided design (CAD) software to design the crown, customizing its shape and size to ensure a precise fit.
4. The crown is then milled from a block of ceramic in the dental office using computer-aided manufacturing (CAM) technology.
5. Finally, the dentist bonds the crown to the prepared tooth, completing the procedure in a single visit.

The use of CEREC technology eliminates the need for temporary crowns and multiple dental visits, providing a convenient and time-saving option for patients.

Summary:

The dental crown procedure involves either traditional crowns or CEREC crowns. Traditional crowns require multiple visits, with a temporary crown placed while the permanent crown is being made in a dental lab. CEREC crowns, on the other hand, can be completed in a single visit using CAD/CAM technology. With advancements in dental technology, patients now have the option of choosing the most suitable method for their crown placement needs.

Dental Crown Materials

When it comes to dental crowns, there are several materials that can be used depending on the patient’s needs and preferences. Each type of material has its own unique properties and advantages. Let’s take a closer look at some of the most commonly used dental crown materials:

Gold Alloys

Gold alloy crowns have been used in dentistry for decades and are known for their strength and durability. They offer excellent longevity and can withstand the forces of biting and chewing. One of the main advantages of gold crowns is their biocompatibility, meaning they are less likely to cause any allergic reactions. However, their metallic appearance may not be suitable for patients who prioritize aesthetics.

Porcelain-Fused-to-Metal (PFM)

Porcelain-fused-to-metal crowns combine the strength of metal with the natural look of porcelain. They are a popular choice because they offer a good balance between strength and aesthetics. The metal substructure provides durability, while the outer layer of porcelain mimics the color and translucency of natural teeth. However, over time, the metal margin may become visible at the gumline, resulting in a less natural appearance.

Porcelain Crowns

Porcelain crowns are highly sought after for their unmatched natural appearance. They are made entirely of porcelain, which allows them to closely resemble the color and texture of natural teeth. Porcelain crowns are a great choice for front teeth or other visible areas of the mouth. However, they may not be as strong as other materials and can be more prone to chipping or cracking.

Composite Crowns

Composite crowns are made from a plastic resin material and are generally less expensive compared to other types of crowns. They can be color-matched to the surrounding teeth, providing a natural appearance. However, composite crowns may not be as durable as other materials and may require more frequent repair or replacement.

When choosing a dental crown material, it’s important to consider factors such as strength, aesthetics, durability, and cost. Your dentist can guide you in making the best decision based on your individual needs and preferences.

Your dentist will take precautions to minimize the risk of nerve damage, but it is important to be aware of this potential complication.

3. Root Canal Failure

In certain situations, a dental crown can cause a previously treated root canal to fail. This can occur if the crown puts excessive pressure on the tooth, leading to complications or damage to the root canal. Your dentist will evaluate the condition of your tooth and discuss the potential risks and benefits of dental crowns in order to make the best treatment decision for your specific situation.

While these risks exist, it is important to remember that dental crowns are a common and generally safe dental treatment. Your dentist will carefully assess your individual case and provide recommendations based on your unique dental health needs.

“Understanding the potential risks of dental crowns can help you make an informed decision about your dental health.”

Same-Day Dental Crowns

Advancements in dental technology have made it possible for patients to receive same-day dental crowns, thanks to CAD/CAM technology. This innovative approach allows dentists to create custom crowns right in their office, eliminating the need for multiple visits and temporary crowns.

With same-day dental crowns, the process is streamlined and efficient. The dentist will use a digital scanner to capture a precise image of your tooth, eliminating the need for messy impressions. This digital impression is then used to design and fabricate your custom crown on-site.

The CAD/CAM technology used in same-day crowns provides accurate and precise results. The process involves computer-aided design (CAD) to digitally design the crown, followed by computer-aided manufacturing (CAM) to mill the crown out of a solid block of ceramic material. The result is a strong and durable crown that blends seamlessly with your natural teeth.

Same-day dental crowns offer numerous benefits to patients. Not only do they save time by avoiding multiple visits, but they also provide immediate restoration for damaged teeth. With CAD/CAM technology, patients can leave the dental office with a beautifully restored tooth in just one appointment.

Care for Dental Crowns

Proper care is essential for maintaining the longevity of dental crowns. By following a few simple steps, you can keep your crowns in optimal condition and ensure they continue to protect and enhance your smile.

1. Dental Crown Maintenance

Regular brushing and flossing are crucial for maintaining healthy teeth and gums, including those with dental crowns. Use a soft-bristled toothbrush and fluoride toothpaste to gently clean your teeth, paying attention to the area where the crown meets the gumline. Avoid using excessive force or abrasive toothpaste, as this can damage the crown’s surface.

In addition to daily brushing, it’s important to floss around the crown to remove plaque and food particles that can accumulate between the teeth. Use a floss threader or waxed floss to navigate around the crown and ensure thorough cleaning.

2. Regular Dental Check-Ups

Scheduling regular dental check-ups is vital for monitoring the condition of your dental crowns and overall oral health. During these visits, your dentist will examine the crowns for any signs of wear, damage, or decay. They will also assess the underlying teeth and gums to identify and address any potential issues.

Your dentist may recommend professional cleaning to remove any tartar or plaque that has accumulated around the crown. Regular check-ups allow for early detection and intervention, preventing further damage and ensuring the longevity of your dental crowns.

3. Healthy Oral Habits

In addition to proper maintenance and regular dental check-ups, adopting healthy oral habits can further enhance the longevity of your dental crowns. Avoid chewing on hard objects such as ice, pens, or fingernails, as this can cause damage to the crown or underlying tooth structure.

If you grind or clench your teeth, known as bruxism, discuss this with your dentist. They may recommend a nightguard or other protective measures to prevent damage to your crowns. It’s also essential to maintain a balanced diet and limit the consumption of sugary and acidic foods and beverages, as these can contribute to tooth decay and compromise the integrity of your crowns.

By following these care guidelines and maintaining regular dental visits, you can ensure the longevity and functionality of your dental crowns, allowing you to enjoy a healthy, beautiful smile for years to come.

Alternatives to Dental Crowns

If dental crowns are not the best option for your dental needs, there are several alternatives available that can help restore and improve the appearance and function of your teeth.

Dentures

Dentures are removable prosthetic devices that replace missing teeth and surrounding tissues. They come in two types: complete dentures for those missing all of their teeth and partial dentures for those missing only a few teeth. Dentures are custom-made to fit your mouth and are held in place by suction or with the help of dental adhesives. While dentures can be an effective solution to restore your smile, they may require adjustments over time due to changes in the jawbone and gum tissue.

Dental Bridges

Dental bridges are fixed prosthetic devices that replace one or more missing teeth. They consist of artificial teeth (pontics) that are held in place by dental crowns on the adjacent teeth. Dental bridges can restore the appearance and function of missing teeth, but they require the preparation of the adjacent teeth to support the crowns. It is important to maintain good oral hygiene and visit the dentist regularly to ensure the longevity and success of dental bridges.

Veneers

Veneers are thin, custom-made shells that are bonded to the front surface of the teeth to improve their appearance. They can be used to correct issues such as stained or discolored teeth, chipped or broken teeth, and gaps between teeth. Veneers are made from porcelain or composite resin and provide a natural-looking and durable solution. However, they require the removal of a small amount of enamel from the tooth surface for proper placement.

Tooth Rebuilding with Fillings

If the damage to your tooth is minimal, tooth rebuilding with fillings may be an alternative to dental crowns. This procedure involves removing decayed or damaged tooth structure and filling the cavity with a dental filling material such as composite resin or amalgam. The filling restores the shape and function of the tooth while providing protection against further damage. Tooth rebuilding with fillings is a less invasive option compared to dental crowns but may not be suitable for extensive tooth damage.

It is important to consult with your dentist to determine the most appropriate alternative to dental crowns based on your specific dental needs and conditions. Your dentist will evaluate the condition of your teeth and provide recommendations for the best treatment options.

Conclusion

In conclusion, dental crowns are a versatile and effective solution for restoring and protecting damaged teeth. Whether you have a weak, broken, or decayed tooth, a dental crown can provide the strength and support needed to improve your dental health. With a variety of materials available, including metal, porcelain, and composite, you can choose the option that best suits your needs and preferences.
