What is a Dental Crown and Why Might Your Tooth Need One?

A dental crown is a tooth-shaped cap that's placed over a tooth to restore its shape, size, strength, and improve its appearance. Think of it like a protective helmet for your tooth. This article explains everything you need to know about dental crowns, from the different materials used to the procedure involved, and why it is worth considering if you have a damaged or decayed tooth. As ISTAR Dental Supply, we are dedicated to providing the highest quality manufacturing for dental equipment, with our eyes set on providing products for dental clinics, dentists, dental schools, dental labs, and dental hospitals.

1. What Exactly is a Dental Crown?

A dental crown is a tooth-shaped "cap" that is placed over a tooth. It covers the visible portion of the tooth above the gum line. The crown is a tooth-shaped cap that restores the tooth's shape, size, strength, and appearance. The purpose is to protect and restore the tooth structure when it's been compromised by decay, damage, or other issues. Dental crowns are designed to look and function just like your natural teeth.

At ISTAR Dental Supply, we understand the critical role a well-made dental crown plays in restoring a patient's smile and oral health. We make dental crowns using modern technology and materials.

2. Why Would I Need a Dental Crown?

There are several situations where your dentist might recommend a dental crown. You may need a dental crown in the following situations:

• Extensive Decay: If a tooth has a large cavity that's too big for a filling, a dental crown can restore its structure.
• Broken or Cracked Tooth: A broken tooth or a significantly cracked tooth can be protected and strengthened with a dental crown.
• After a Root Canal: A tooth that has undergone a root canal often becomes brittle and needs a crown for protection.
• Cosmetic Enhancement: Dental crowns can be used to improve the appearance of misshapen, discolored, or worn-down teeth.
• To Support a Dental Bridge: Dental crowns serve as anchors for a dental bridge, which replaces missing teeth.
• To cover Dental Implant: A dental crown is the best option for a dental implant.

If you're experiencing any of these dental issues, consult your dentist to see if you need a crown.

3. What Are the Different Types of Dental Crowns?

There are many types of dental crowns available, each with its own advantages and disadvantages. Here's a breakdown of the several types available:

• Metal Crowns: These are made from alloys like gold, palladium, nickel, or chromium. Metal crowns rarely chip or break, and they withstand biting and chewing forces well. They are a good choice for out-of-sight molars.
• Porcelain-Fused-to-Metal (PFM) Crowns: These have a metal base for strength and a porcelain layer for a more natural look. However, the porcelain can sometimes chip, and the metal may show through as a dark line near the gums.
• All-Ceramic or All-Porcelain Crowns: These provide the best natural color match and are a good option for front teeth. All-porcelain crowns are also a good choice for people with metal allergies.
• Zirconia Crowns: Zirconia crowns are incredibly strong and durable, making them a good choice for both front and back teeth. They offer a good balance of aesthetics and strength.
• Resin Crowns: Made from dental composite resin, resin crowns are another option.

The best type of crown for you will depend on your specific needs, the location of the tooth, and your budget. We at ISTAR Dental Supply, offer materials for all types of dental crowns to your dentist or dental professional.

Here's a table summarizing the different types of dental crowns:

4. What is the Dental Crown Procedure Like?

The dental crown procedure typically involves two dental visits:

First Visit: Tooth Preparation and Temporary Crown

1. Examination and Preparation: Your dentist will examine the tooth, take X-rays, and numb the area. Prepare the tooth by removing any decay and shaping the tooth for a crown, to make room for the crown.
2. Impression: An impression of your tooth and the surrounding teeth is taken. This is sent to a dental laboratory where your custom dental crown will be fabricated.
3. Temporary Crown Placement: A temporary dental crown is placed to protect the prepared tooth while your permanent crown is being made.

Second Visit: Permanent Crown Placement

1. Removal of Temporary Crown: Your dentist will remove the temporary crown.
2. Fitting and Adjustment: The new crown is tried on, and any necessary adjustments are made to ensure a proper fit and bite.
3. Cementation: Once the crown fits perfectly, it's permanently cemented to the tooth. Your permanent crown is ready.

5. How Long Does a Dental Crown Last?

Crowns can last between five and 15 years, or even longer, with proper care. The lifespan of a dental crown depends on several factors, including:

• Oral Hygiene: Brushing twice a day, flossing daily, and regular dental visits are crucial for maintaining the health of your tooth under the crown and preventing decay.
• Diet: Avoid chewing hard foods, ice, or sticky candies that could damage the crown.
• Habits: If you grind or clench your teeth, your dentist may recommend a nightguard to protect your crown.
• Crown Material: Some materials, like zirconia, are more durable than others.

With diligent dental care, your dental crown can provide many years of reliable service.

6. How Much Does a Dental Crown Cost?

The cost of a crown can vary widely depending on several factors:

• Material: Metal crowns are generally less expensive than other types, while all-ceramic or zirconia crowns tend to be more expensive.
• Location: The cost of dental procedures can vary by geographic region.
• Dentist's Fees: Each dentist sets their own fees for procedures.
• The complexity of the procedure: The complexity of the dental crown procedure.
• Location of the tooth: Crowns on front teeth can be more complex.

It's best to discuss crown costs with your dentist to get an accurate estimate for your specific situation. Remember that investing in a high-quality dental crown is an investment in your long-term oral health.

7. How a Dental Crown is created?

The creation of a dental crown is a blend of artistry and precise technology. Here's a look at the process:

1. Digital or Traditional Impressions: As discussed, your dentist will take an impression of your prepared tooth. This can be done traditionally with putty-like material or digitally using an intraoral camera. Digital impressions are becoming increasingly common due to their accuracy and comfort.
2. CAD/CAM Technology: If a digital impression is taken, the data is sent to a computer-aided design/computer-aided manufacturing (CAD/CAM) system. This technology allows for the precise design and milling of the crown from a block of ceramic, zirconia, or other chosen material.
3. Dental Lab Fabrication: If a traditional impression is used, it's sent to a dental lab. Skilled technicians use the impression as a mold to create the crown. They carefully sculpt the crown to match the shape, size, and color of the permanent crown of your surrounding teeth.
4. Material Selection: The chosen crown material (porcelain, zirconia, metal, etc.) is selected based on your dentist's recommendation and your preferences.
5. Layering and Firing (for Porcelain Crowns): For porcelain crowns, the technician layers different shades of porcelain to mimic the natural translucency of a tooth. The crown is then fired in a special oven to harden and strengthen the material.
6. Finishing Touches: Once the crown is made, it's polished and checked for any imperfections. The lab ensures the crown meets the exact specifications provided by your dentist.

8. Temporary vs. Permanent Dental Crowns: What's the Difference?

It's important to understand the distinction between temporary and permanent crowns:

• Temporary Dental Crowns: These are used as a short-term solution while your permanent crown is made. Temporary crowns are made from acrylic or composite resin and are not as strong or durable as permanent crowns. They are meant to protect the prepared tooth, prevent sensitivity, and maintain the space for the permanent crown. Your dentist will place a temporary crown in your mouth. Temporary crown to cover and protect the tooth.
• Permanent Dental Crowns: These are custom-made to fit your tooth precisely and are designed for long-term use. They are fabricated from stronger materials like porcelain, zirconia, or metal alloys. Once the crown is usually created, it provides lasting protection, function, and aesthetics.

9. Caring for Your Dental Crown: Ensuring Longevity

Proper care is essential to maximize the lifespan of your dental crown:

• Brush and Floss Regularly: Brush your teeth, including the crowned tooth, twice a day with fluoride toothpaste. Floss daily to remove plaque and debris from around the crown and between your teeth.
• Avoid Hard Foods: Be cautious when chewing hard foods, ice, or other objects that could potentially chip or crack the crown.
• Address Teeth Grinding: If you grind or clench your teeth (bruxism), talk to your dentist about wearing a nightguard to protect your crown and other teeth from damage.
• Regular Dental Checkups: Schedule regular dental visits for checkups and cleanings. Your dentist can monitor the condition of your crown and address any potential issues early on.

10. What are the benefits of a Dental Crown?

Dental Crowns Offer Several Benefits:

• Restores Tooth Function: A dental crown allows you to chew and speak properly if you have a damaged or weakened tooth.
• Protects Weakened Teeth: It provides a protective shell for a tooth that is cracked, broken, or has undergone a root canal.
• Improves Appearance: Dental crowns can significantly enhance the aesthetics of your smile by correcting misshapen, discolored, or damaged teeth.
• Supports Dental Bridges: They serve as anchors for dental bridges, replacing missing teeth and restoring your bite.
