Filling vs Crown vs Root Canal Explained

Mar 01, 2024

Welcome to our extensive guide on dental procedures designed to address tooth decay. Dental health is paramount for overall well-being, and when confronted with decay, it is crucial to comprehend the available treatment options. This blog post will explore three standard dental procedures: fillings, crowns, and root canals. By understanding the distinctions between these treatments, you can make wise decision about your oral health.

Filling: The Conservative Approach to Tooth Decay

A filling is often the recommended treatment when dental decay is detected early. A filling entails the removal of the decayed part of the tooth and filling the resulting cavity with a dental material.

Types of Fillings

  1. Amalgam Fillings:
    • Composed of a mixture of metals
    • Known for their durability and affordability
  1. Composite Fillings:
    • Made of a tooth-colored resin material
    • Blend in with the natural tooth color, thus, providing a more aesthetically pleasing option
    • It is less durable compared to amalgam fillings but offers a conservative approach

How Fillings Are Done

  1. Anesthetizing the tooth and surrounding area to ensure comfort during the procedure.
  2. Eliminating the decayed portion of the tooth involves using specialized dental instruments.
  3. Preparing the cavity by cleaning and disinfecting it.
  4. Applying the chosen filling material in layers and curing it with a special light.
  5. Shaping and polishing the filling for a natural appearance and proper bite.

Pros and Cons of Fillings


  • Quick and straightforward procedure
  • Less invasive than other treatments
  • Preserve most of your natural tooth structure.
  • Cost-effective option compared to crowns and root canals


  • Limited durability, especially for composite fillings
  • It may require replacement or repair over time
  • Not suitable for extensive decay or weakened teeth

Crown: Restoring Structural Integrity with a Dental Cap

When tooth decay progresses beyond what a filling can address, a dental crown, also known as a dental cap, is often recommended. A crown is a protective cover, restoring the tooth’s shape, size, and strength.

When is a Dental Crown Recommended?

  1. Extensive Decay:
    • When a large portion of the tooth is affected by decay
    • In cases where a filling would compromise the tooth’s structural integrity
  1. Fractured or Weakened Teeth:
    • Teeth that are weakened due to trauma or previous dental work
    • Teeth with cracks, fractures, or areas of significant wear

The Process of Placing a Dental Crown

  1. Numbing the area to ensure a painless experience.
  2. Reshaping the tooth to provide room for the crown.
  3. Taking impressions of the tooth to create a custom-fit crown.
  4. A temporary crown is being placed while the permanent one is being fabricated.
  5. Cementing the permanent crown onto the reshaped tooth.

Advantages and Disadvantages of Dental Crowns


  • Provides significant structural support for weakened teeth
  • Restores the appearance and functionality of damaged teeth
  • Offers long-lasting protection when cared for properly


  • It involves a more extensive procedure than fillings
  • Requires removing a significant portion of the natural tooth
  • Higher cost compared to fillings

Root Canal: Saving the Tooth from Extraction

When dental decay penetrates the innermost layer of the tooth, known as the dental pulp, a root canal treatment becomes necessary to rescue the tooth from extraction. This process includes the removal of the infected pulp, thoroughly cleaning the root canals, and sealing them to prevent additional infection.

Signs and Symptoms of Need for a Root Canal

  • Intense tooth pain, particularly when pressure is applied.
  • Persistent sensitivity to hot or cold temperatures
  • Gum swelling or tenderness in the vicinity of the affected tooth.
  • Discoloration or darkening of the tooth

What Happens During a Root Canal Treatment?

  1. Numbing the area to ensure a painless procedure.
  2. Accessing the tooth’s pulp chamber and canals.
  3. Extracting the infected pulp and cleansing the canals.
  4. Shaping the canals and filling them with dental material.
  5. A temporary filling or crown protects the tooth until a permanent restoration is applied.

Benefits and Drawbacks of Root Canal Therapy


  • It saves the tooth from extraction, preserving natural aesthetics and functionality
  • Eliminates tooth pain caused by infection or inflammation
  • It prevents the spread of infection to nearby teeth.


  • It may require additional dental work, such as a dental crown, to provide structural support
  • Multiple visits may be required to complete the treatment process
  • Root canal-treated teeth are more susceptible to fracture and may require extra care
