Introduction:

Dental crowns are a vital component of restorative dentistry, offering both functional and aesthetic benefits. Whether you're dealing with a damaged tooth, want to enhance your smile, or need to protect a weakened tooth, dental crowns provide a reliable solution. In this detailed guide, we will explore what dental crowns are, why you might need one, the different types available, and what to expect during the procedure. We’ll also discuss the benefits, risks, and how to care for your crown to ensure it lasts for years.

What is a Dental Crown?

A dental crown is a custom-made cap that covers a damaged, decayed, or unattractive tooth. It restores the tooth’s shape, size, strength, and appearance. Crowns can be made from various materials, including porcelain, metal, or a combination of both, and are designed to blend seamlessly with your natural teeth.

When Would You Need a Dental Crown?

Dental crowns are recommended in several situations, including:

To protect a weak tooth from breaking or to hold together parts of a cracked tooth.

To restore an already broken or severely worn down tooth.

To cover and support a tooth with a large filling when there isn’t much tooth left.

To hold a dental bridge in place.

To cover misshapen or severely discolored teeth.

To cover a dental implant.

To make a cosmetic modification to improve the appearance of a smile.

There are several types of dental crowns available, each with its own advantages:

Metal crowns

Dental technicians use several metals to make dental crowns, including gold, palladium, nickel and chromium. Metal crowns rarely chip or break, last the longest in terms of wear and only require a small amount of enamel removal. They can also withstand biting and chewing forces.

The metallic color is the main drawback of this type of crown. Metal crowns are a good choice for out-of-sight molars.

Porcelain-fused-to-metal (PFM) crowns

Porcelain-fused-to-metal (PFM) crowns combine the durability of metal and the natural look of porcelain. Dentists can match these crowns to the shade of your own teeth.

Despite their strength, PFM crowns have some drawbacks. For example, the porcelain coating may chip off over time, exposing the metal underneath. In addition, PFM crowns may gradually wear down the enamel on your opposing teeth (the teeth that touch your crown when you close your mouth).

PFM crowns last almost as long as metal crowns. They can restore both front and back teeth.

Pressed ceramic crowns

A pressed ceramic crown has a hard inner core. It’s similar to a PFM, but the core is ceramic instead of metal. To make this inner core, a technician melts and presses ceramic in an oven at a very high temperature. Next, they add multiple layers of porcelain. Like all-porcelain crowns, pressed ceramic crowns mimic the translucency of natural tooth enamel.

Pressed ceramic crowns have the same drawbacks as PFM crowns. The layers of ceramic can chip away over time. Dentists use pressed ceramic crowns on front and back teeth.

All-ceramic or porcelain crowns

All-ceramic or porcelain crowns mimic the appearance of tooth enamel more than any other crown type. They’re also a good choice if you have metal allergies.

Lab technicians use many different materials to make ceramic crowns, but one of the most popular is zirconium dioxide. Zirconia crowns are extremely durable and can withstand heavier forces than other types of ceramic crowns. They’re also gentle on your opposing teeth, resulting in less enamel wear.

Same-day dental crowns

Many dentists use CAD/CAM (computer-aided design and manufacturing) technology to create crowns in their office while you wait. This software allows your dentist to take digital dental impressions of your teeth, and then use those impressions to design a custom crown. Once your dentist designs your crown, they’ll send the image files to an on-site milling machine. The machine will craft your new crown from a solid block of ceramic.

The main advantage of CAD/CAM technology is that you can get a dental crown in just one office visit. However, same-day crowns aren’t for everyone. Ask your dentist if you’re a candidate.

All-resin crowns

Dental crowns made out of resin are generally less expensive than other types of crowns. But they’re fragile and more likely to break compared to porcelain-fused-to-metal (PFM) crowns.

Dentists often use resin to make temporary crowns. They last three to five years on average.

• First Visit: Preparation:

• Examination and X-rays: The dentist will examine the tooth and take X-rays to check the roots and surrounding bone.
• Tooth Preparation: The tooth receiving the crown is reshaped to accommodate the crown. If the tooth is severely damaged or decayed, a filling material may be used to build up the tooth.
• Impression: After shaping, an impression of the tooth is made and sent to a dental lab where the crown is custom-made. A temporary crown is placed over the tooth to protect it.

• Second Visit: Crown Placement:

• Temporary Crown Removal: The temporary crown is removed, and the custom-made crown is placed on the tooth.
• Cementing: The dentist checks the fit and color of the crown. If everything looks good, the crown is permanently cemented into place.

What are the Benefits of Dental Crowns?

• Restoration of Function: Crowns restore the ability to bite and chew normally.
• Protection: They protect weak teeth from further damage or decay.
• Aesthetic Improvement: Crowns can significantly enhance the appearance of damaged or discolored teeth.
• Durability: With proper care, crowns can last many years, providing long-term benefits.

What are the Risks of Dental Crowns?

• Sensitivity: Some patients may experience sensitivity to hot or cold temperatures after getting a crown.
• Chipping or Breaking: Although rare, crowns made of porcelain can chip or break under excessive force.
• Loose Crown: Over time, the cement that holds the crown in place may wear out, causing the crown to become loose.
• Allergic Reactions: Although uncommon, some patients may have allergic reactions to the materials used in the crown.

How Long Does It Take to Feel Better After a Dental Crown Procedure?

Most patients feel better within a few days after the procedure. It’s normal to experience some sensitivity or discomfort initially, but this usually subsides quickly.

Foods to Avoid with a Crown To prolong the life of your crown, it’s advisable to avoid:

Hard foods like nuts and ice that could crack the crown.

Sticky foods like caramel and chewing gum that could pull the crown off.

Sugary foods that can lead to decay around the crown.

Are Dental Crowns Permanent? Dental crowns are not permanent, but they are long-lasting. With proper care, a crown can last anywhere from 10 to 30 years. The longevity depends on the material used, the location of the crown, and your oral hygiene practices.

Additional Details

Veneers vs. Crowns: Which Option is Right for Me? Veneers are a thinner, more conservative option that only covers the front surface of the tooth, making them ideal for cosmetic changes. Crowns, on the other hand, encase the entire tooth and are better for teeth that need strengthening or have significant damage.

What’s the Most Common Alternative to a Crown? A common alternative to a crown is a dental veneer or an inlay/onlay. These options are less invasive but may not provide the same level of protection as a crown, particularly for teeth that are heavily damaged.

Dental Cap vs. Crown: Is There a Difference? The terms "dental cap" and "crown" are often used interchangeably. Both refer to the same dental restoration used to cover and protect a damaged tooth.
