Top 6 Factors that Impact the Cost of a Tooth Filling Replacement

When your child has a cavity or damaged tooth, the dentist will likely repair the tooth with a filling. Fillings, also called dental restorations, are a very common way to restore a damaged tooth to its normal function and appearance.

Generally, tooth fillings only last for five to fifteen years. That means that, eventually, most fillings will need replacing. Here’s what you need to know about the cost of replacing a filling:

What Factors Affect the Cost of a Tooth Filling Replacement?

No two fillings are exactly alike, and the cost of replacing a filling can vary. In pricing your child’s filling, the dentist will consider the following factors:

  1. Placement of the filling. An easy-to-reach tooth filling will cost less than a filling in a tooth that’s tucked away near the back of the mouth. Tough-to-reach teeth can require more equipment and more time to fill.
  2. The tooth’s function. A tooth that’s subject to chewing and grinding will demand a more durable filling. Stronger filling materials are more costly.
  3. Time. If there’s an infection or something else that needs to be taken care of before the tooth can be filled, your child may need more than one appointment. Each appointment and procedure carries its own cost.
  4. The dentist. Different dentists have different rates, and they have different agreements with insurance providers.
  5. Location. Rates vary by location. Dentists in different states, regions, and cities may have very different rates.
  6. Type of filling. This is typically the largest factor when it comes to cost. Whether you decide on a stronger or more natural looking material vs. something less costly is up to you and what your dentist recommends.

Replacement Filling Materials and Costs

Let’s take a closer look at each type of filling material and its cost:


Amalgam is a mixed-metal filling material. It’s made of a combination of silver, tin, zinc, copper, and mercury. Amalgam is the least expensive dental filling material and typically lasts about ten years.

The average cost for an amalgam filling is between $110 and $200.

Composite Resin

A composite resin filling is made with plastic and glass. It’s tooth-colored, so it’s a great option if appearance is a concern. A composite resin filling is more expensive than amalgam and can last up to five years.

A composite filling costs $135 to $240, on average.

Cast Gold

Naturally, of the three options, gold is the most expensive filling material. Gold fillings are exceptionally durable and can last for fifteen years.

Cast gold fillings cost as much as ten times more than amalgam.
