Dental Crown vs Filling: What’s the Difference?

Table of Contents

Tooth damage can occur in various ways. When it does, your dentist will usually recommend a crown or a filling to repair it. These restorative treatments protect and strengthen teeth, but they work differently and are used for different levels of damage. 

Knowing when each treatment is appropriate helps you understand what your local dentist is recommending and why. 

In this blog, we’ll walk through the differences between crowns and fillings, how each one works, and the types of problems they’re best suited to fix.

What is a Dental Crown?

A dental crown is a custom-made cap that completely covers a damaged or weakened tooth. It acts as a protective shield, restoring the tooth’s shape, strength, and function.

Crowns in St Clair can be crafted from various materials, such as porcelain, metal, or ceramic, each offering distinct advantages in durability and aesthetics. When a tooth has suffered extensive decay, undergone root canal treatment, or sustained a fracture, a dental crown is the recommended solution.

The Process of Getting A Dental Crown

Here’s a step-by-step look at what to expect when getting a crown:

  1. Examination and Assessment: We begin with a thorough clinical examination and may take X-rays to assess the tooth’s condition and determine whether a crown is suitable.
  2. Preparation: The tooth is gently prepared by removing any damaged or decayed areas. Local anaesthetic is used where needed to keep you comfortable throughout the process.
  3. Impression or Digital Scan: Instead of traditional impressions, a digital scan is taken to create a precise 3D model of your tooth. This allows for accurate design and fit.
  4. Same-Day Crown Design and Placement: Using CEREC technology, your crown is designed and created on-site. In many cases, the final crown can be fitted on the same day, without the need for a temporary crown or multiple visits.
  5. Final Placement: Once ready, the crown is carefully fitted and adjusted to ensure comfort and proper bite alignment, restoring the tooth’s strength and function.

When Is a Crown Recommended?

You might need a dental crown if:

  • Your tooth is significantly weakened by decay or has a large filling.
  • You have undergone a root canal and need additional support for the treated tooth.
  • Your tooth is cracked or broken and requires full coverage.
  • You wish to improve the appearance of a discoloured or misshapen tooth.
  • A crown is needed as an anchor for a dental bridge or as part of a dental implant treatment for replacing missing teeth.

What is a Dental Filling?

A dental filling is used to repair a tooth that has been affected by minor to moderate decay or damage. The process involves removing the decayed portion of the tooth and filling the cavity with a restorative material such as composite resin. Tooth fillings are a conservative treatment option that preserves as much of your natural tooth structure as possible while preventing further decay.

The Filling Procedure

The process of getting a filling is relatively quick and straightforward, with a few steps involved. 

  1. We start with an examination to determine the extent of decay or damage.
  2. The affected area is numbed to ensure you remain comfortable throughout the procedure.
  3. The decayed portion of the tooth is carefully removed.
  4. The cavity is then filled with your chosen material, which is shaped and polished to blend naturally with your tooth.

When Do I Need a Dental Filling?

Fillings are excellent for preserving as much of your natural tooth as possible. They’re a more conservative approach to dental restoration. That’s why they are important in helping solve the following dental issues:

  • Cavities: Fillings are most commonly used to treat cavities caused by tooth decay, preventing further spread.
  • Chipped Teeth: Teeth that have been chipped or fractured due to accidents or trauma can be repaired using fillings.
  • Tooth Wear: If teeth are worn down due to grinding or clenching, fillings can help restore their original shape and function.
  • Cosmetic Corrections: Fillings can also be used for minor cosmetic enhancements, such as closing small gaps or correcting irregularities.

Key Differences Between a Crown and a Filling

Now that we’ve explored the ins and outs of dental crowns and fillings, let’s pinpoint the key differences that set these two treatments apart:

Purpose

A dental crown provides structural support and protects weakened or damaged teeth, while fillings repair a small portion of a tooth from cavities or tooth damage from decay or injury. Crowns cover the entire tooth, while fillings target specific damage.

Tooth Preservation

Fillings are the go-to choice when it comes to preserving as much of your natural tooth structure as possible, requiring minimal removal of damaged areas. Crowns, on the other hand, require more extensive reshaping and may result in significant tooth reduction.

Extent of Damage

A crown is for substantial damage that compromises the tooth’s core structure, while a filling works best for minor to moderate damage, keeping the tooth’s core intact.

Durability 

Dental crowns are stronger and last longer, making them ideal for teeth that are heavily damaged or weakened. Fillings are best for minor repairs but may not withstand heavy pressure over time.

Procedure & Cost 

Fillings are quicker and less expensive, while crowns require more preparation, multiple visits, and a higher cost.
