Why Some Dental Fillings May Cost $150 or $400: Size and Surfaces Explained

Have you ever wondered why one dental filling may cost around $150 while another may cost $400? The difference often comes down to the size of the cavity, the number of tooth surfaces involved and the treatment your tooth needs.  

Our team at Markham Street Dental believes that understanding your dental treatment helps you make informed decisions about your smile’s health. Let’s take a look at tooth fillings, what affects their cost and why addressing tooth decay early is important.

Not All Cavities Are the Same

When tooth decay develops, your dentist assesses how much of the tooth is affected and determines the most suitable treatment for your unique case. A small filling may repair a cavity on just one surface of a tooth, while a large filling may involve two or three surfaces, such as the top and side of a molar. 

The more extensive the damage, the more complex the restoration may be. Your dentist in Armidale, NSW, considers:

  • The size and location of the cavity
  • The remaining healthy tooth structure
  • The material used when planning treatment

How Much Can a Dental Filling Cost?

The cost of a filling depends on the tooth, the surfaces requiring treatment and the complexity of the procedure. As a guide, the following prices show how costs may vary:

  • Small, one-surface filling — from around $150
  • Medium, two-surface filling — from around $250
  • Larger, three-surface filling — from around $400 

These figures are examples, not a confirmed Markham Street Dental fee schedule. The only way to determine the estimated cost of treatment is to book a consultation, receive a thorough exam and have a chat with the dentist. We can also review health fund rebates with you. 

What Happens If You Leave a Cavity Untreated?

A small cavity may seem harmless, especially if it doesn’t hurt. However, tooth decay can progress through the enamel and into the softer dentin beneath it. As the decay advances, the damage may extend closer to the dental pulp, which contains the tooth’s nerves and blood vessels. 

You may develop sensitivity, toothache or pain when chewing, although some cavities cause few noticeable symptoms. A filling may no longer be enough if decay reaches the pulp or the tooth develops irreversible inflammation or infection.  

From a Tooth Filling to Root Canal Treatment 

When the pulp becomes inflamed or infected, your Armidale dentist may recommend root canal treatment to:

  • Remove the affected tissue
  • Clean the inside of the tooth
  • Seal the tooth
  • Cap it with a crown for protection, depending on the damage 

Root canal treatment can involve more time and expense than many routine dental fillings. However, the right treatment depends on your individual circumstances, and not every cavity progresses to this stage.
