What Type of Dental Procedure is a Crown

A dental crown is a common dental procedure that involves the placement of a cap over a damaged or decayed tooth. It is a versatile restorative option that can help restore the appearance, strength, and functionality of a tooth. In this article, we will explore the various aspects of dental crowns, including their types, benefits, procedure, aftercare, and more.

1. What are Dental Crowns?

Dental crowns, also known as dental caps, are custom-made prosthetic restorations that are placed over a damaged tooth. They cover the entire visible portion of the tooth above the gumline and are designed to mimic the shape, size, and color of a natural tooth. Crowns can be made from different materials, such as porcelain, ceramic, metal, or a combination of these materials.

Dental crowns serve multiple purposes, including:

Restoring severely decayed or damaged teeth
Strengthening weakened teeth
Improving the appearance of misshapen or discolored teeth
Supporting dental bridges
Protecting teeth after root canal treatment

2. Types of Dental Crowns

There are several types of dental crowns available, and the choice of crown depends on various factors, including the location, function, and aesthetic requirements. The most common types of dental crowns include:

Porcelain Crowns

Porcelain crowns are popular due to their natural appearance and excellent aesthetics. They blend seamlessly with the surrounding teeth, making them an ideal choice for front teeth restorations. However, porcelain crowns may be more prone to chipping and cracking compared to other materials.

Ceramic Crowns

Ceramic crowns are similar to porcelain crowns in terms of aesthetics but are more durable. They are known for their outstanding strength and are an excellent choice for both front and back teeth restorations. Ceramic crowns are highly resistant to wear and provide a natural look and feel.

Metal Crowns

Metal crowns, often made of gold or base metal alloys, are extremely strong and long-lasting. They offer excellent durability and require minimal removal of tooth structure during the preparation. However, metal crowns are not as aesthetically pleasing as porcelain or ceramic crowns and are typically used for molars and pre-molars.

Porcelain-Fused-to-Metal Crowns

Porcelain-fused-to-metal (PFM) crowns combine the strength of metal with the aesthetics of porcelain. These crowns have a metal base for strength and a layer of porcelain on top for natural appearance. PFM crowns are versatile and can be used in different areas of the mouth.

3. The Dental Crown Procedure

The dental crown procedure generally involves multiple steps and may require two or more dental visits. Here is an overview of the typical dental crown procedure:

1. Consultation and Examination

The first step is to schedule a consultation with your dentist. They will examine your teeth, take X-rays, and assess the condition of the tooth that requires a crown. Your dentist will discuss the procedure, address any concerns or questions you may have, and create a treatment plan tailored to your specific needs.

2. Tooth Preparation

The tooth receiving the crown will be prepared by removing a portion of its outer structure. This is necessary to create space for the crown to fit comfortably over the tooth. Your dentist will numb the area with a local anesthetic, ensuring a pain-free experience. In some cases, if the tooth is severely damaged or decayed, it may require additional restoration, such as a dental filling or a root canal, before crown placement.

3. Impression Making

Once the tooth is prepared, your dentist will take impressions of your teeth. These impressions will serve as a model for the dental laboratory to fabricate the custom crown. Your dentist may use traditional putty-like material or digital scanning technology to create accurate impressions.

4. Temporary Crown Placement

While your permanent crown is being fabricated, a temporary crown will be placed over the prepared tooth. This temporary crown provides protection and maintains the tooth's appearance and functionality until the permanent crown is ready.

5. Crown Placement

During your second visit, your dentist will remove the temporary crown and check the fit and color of the new crown. Any necessary adjustments will be made before the crown is permanently bonded to the tooth using dental cement. Your dentist will ensure the crown is properly aligned with the neighboring teeth and provide you with instructions for care and maintenance.

4. Aftercare and Maintenance

Proper aftercare and maintenance are essential to ensure the longevity of your dental crown. Here are some important tips to follow:

Good Oral Hygiene

Continue to brush your teeth twice a day and floss daily, paying extra attention to the area around the crown. Fluoride toothpaste and mouthwash can help prevent tooth decay and maintain the health of your natural teeth.

Avoid Chewing Hard Foods

Avoid biting down on hard foods or objects that can potentially damage the crown. These may include ice, hard candies, popcorn kernels, or pen chewing habits. If you engage in activities such as teeth grinding or clenching, your dentist may recommend a nightguard to protect your crown.

Regular Dental Check-ups

Visit your dentist for regular check-ups and professional cleanings at least twice a year. Your dentist will assess the condition of your dental crown and address any concerns or issues promptly.

Protective Measures

If you participate in contact sports or activities that pose a risk of dental injury, it is advisable to wear a mouthguard to protect your dental crown and natural teeth.

5. Cost of Dental Crowns

The cost of dental crowns can vary depending on factors such as the material used, the complexity of the case, geographical location, and the dentist's expertise. On average, the cost of a single dental crown can range from $800 to $1,500. However, it is important to consult with your dentist to get an accurate estimate based on your specific circumstances.

FAQs

1. How long do dental crowns last?

Dental crowns can last anywhere from 10 to 15 years or longer with proper care and maintenance. However, their lifespan can vary based on individual oral hygiene practices, biting forces, and other factors.

2. Are dental crown procedures painful?

No, dental crown procedures are typically not painful. Your dentist will administer local anesthesia to numb the area, ensuring a comfortable experience. Some patients may experience mild sensitivity or discomfort after the procedure, which usually subsides within a few days.

3. Can a dental crown be whitened or bleached?

Unlike natural teeth, dental crowns cannot be whitened or bleached. If your crown becomes stained or discolored, your dentist may recommend replacing it with a new crown to restore its natural appearance.
