What are Dental Crowns

What are dental crowns: also known as a tooth cap, is a custom-made cover that fits over your natural tooth, restoring its shape, size, and functionality. In this comprehensive guide, we will delve into the world of dental crowns, exploring their different types, reasons for getting them, the procedure involved, how to care for them, and much more.

What is a Dental Crown?

A dental crown is a versatile dental restoration that can be made from various materials, including metal, porcelain, zirconia, and ceramic. These materials are carefully chosen based on your specific dental needs. For instance, metal crowns, such as gold or platinum alloys, are known for their durability and ability to withstand biting and chewing forces. On the other hand, porcelain and ceramic crowns provide a more natural appearance that closely resembles your surrounding teeth.

Reasons for Getting a Dental Crown

There are several situations in which your dentist may recommend a dental crown:

  1. To Protect a Weak Tooth: If your tooth is weakened due to decay or a crack, a dental crown can provide the necessary support to prevent further damage or breakage.
  2. To Restore a Broken or Worn-Down Tooth: Dental crowns are an ideal solution for restoring teeth that have been severely worn down or fractured, helping to restore their functionality and aesthetics.
  3. To Support a Dental Bridge: If you have missing teeth and are considering a dental bridge, dental crowns can be used to anchor the bridge in place, ensuring stability and a natural-looking smile.
  4. To Cover Misshapen or Discolored Teeth: Dental crowns can be used to cover teeth that are misshapen, severely discolored, or have undergone cosmetic modifications, providing a uniform and attractive appearance.
  5. To Protect a Tooth After a Root Canal: Following a root canal treatment, a tooth becomes more fragile and prone to fractures. A dental crown can protect and strengthen the tooth, preventing any further damage.

Types of Dental Crowns

Dental crowns come in various types, each offering its own set of advantages and considerations:

  1. Metal Crowns: Made from alloys like gold or platinum, metal crowns are known for their strength and longevity. They are an excellent choice for back teeth that require durability and are not visible when you smile.
  2. Porcelain-Fused-to-Metal (PFM) Crowns: These crowns combine the strength of metal with the natural appearance of porcelain. However, they may show a dark line near the gum line over time, which can be a cosmetic concern for some individuals.
  3. All-Ceramic Crowns: These crowns are made entirely of ceramic or porcelain, providing a highly natural and aesthetically pleasing result. They are an excellent choice for front teeth or anyone concerned about metal allergies.
  4. Zirconia Crowns: Zirconia crowns are known for their strength, durability, and natural appearance. They are highly resistant to chipping and provide excellent aesthetics, making them a popular choice among dentists and patients alike.

The Dental Crown Procedure

The process of getting a dental crown typically involves the following steps:

  1. Initial Examination: Your dentist will conduct a thorough examination, which may include X-rays, to assess the condition of your tooth and determine if a dental crown is the right solution for you.
  2. Tooth Preparation: During this phase, your dentist will remove any decay or old filling material from the tooth. They will then reshape the tooth to create space for the crown, ensuring a precise fit.
  3. Impression Taking: An impression of your prepared tooth and the surrounding teeth will be taken using either digital scans or traditional physical molds. This impression serves as a blueprint for creating your custom-made crown.
  4. Temporary Crown Placement: While your permanent crown is being fabricated at a dental laboratory, your dentist will place a temporary crown over your prepared tooth. This temporary crown protects the tooth and maintains its function and aesthetics.
  5. Permanent Crown Placement: Once your permanent crown is ready, you will return to the dental office for its placement. Your dentist will remove the temporary crown, clean the prepared tooth, and carefully cement the permanent crown in place. They will ensure proper fit, bite alignment, and aesthetics before finalizing the procedure.
  6. Dental crowns restore damaged teeth, improving strength and aesthetics. Choose materials like porcelain for durability and a natural-looking smile makeover.

Caring for Your Dental Crown

Proper care and maintenance are essential for the longevity and health of your dental crown. Here are some tips to help you care for your crown:

  1. Practice Good Oral Hygiene: Brush your teeth at least twice a day with a soft-bristled toothbrush and fluoride toothpaste. Floss daily, paying extra attention to the area around your crown.
  2. Avoid Hard and Sticky Foods: Be cautious when consuming hard or sticky foods, as they can potentially damage or dislodge your crown. Opt for softer and healthier alternatives to protect your crown and natural teeth.
  3. Wear a Nightguard (if necessary): If you tend to grind or clench your teeth at night, your dentist may recommend wearing a nightguard to protect your crown and prevent any potential damage.
  4. Attend Regular Dental Check-ups: Regular dental visits are crucial to monitor the health of your crown and ensure its longevity. Your dentist will examine your crown, clean it professionally, and address any concerns or issues.

The Lifespan of a Dental Crown

The lifespan of a dental crown can vary depending on several factors, including the material used and how well you care for it. On average, dental crowns can last between 10 to 15 years or even longer with proper maintenance. It is essential to follow your dentist’s recommendations for regular check-ups and maintain good oral hygiene practices to extend the lifespan of your crown.

Dental Crown Costs and Insurance Coverage

The cost of a dental crown can vary based on factors such as the type of crown, material used, location, and dental insurance coverage. On average, dental crowns can range from $800 to $1700 or more per crown. It is important to check with your dental insurance provider to understand the coverage details and any limitations or restrictions that may apply.

Alternatives to Dental Crowns

While dental crowns are an effective solution for many dental issues, there are alternative treatments that your dentist may consider based on your specific needs. These alternatives may include dental veneers, dental bonding, inlays, onlays, or orthodontic treatment. It is essential to consult with your dentist to determine the best treatment option for your dental concerns.
