Non-Metal Fillings

We use fillings to fill a cavity formed from tooth decay. We also use them to repair broken or cracked teeth and worn teeth. Below are frequently asked questions about non-metal fillings and metal fillings. At Deldar Dental, we support non-metal fillings.

Non-Metal Fillings FAQ’s

What are the benefits of metal fillings over non-metal fillings?

Silver amalgam fillings are very strong, able to withstand the constant friction of chewing more so than composite resin, porcelain, or glass ionomer fillings.

The silver amalgam fillings last at least 7 years and usually more, while composite resin, porcelain, and glass ionomer fillings last just 5 or more years.

Another benefit of silver amalgam is that the fillings can be installed in one visit, which isn't the case for all fillings, as some other materials require the cavity to be cast in one visit and then filled in a later visit.

Gold foil fillings last even longer, about 10 - 15 years.

Are non-metal fillings more expensive?

Non-metal fillings do cost more but they offer more benefits that silver amalgam fillings.

The exact prices depend on the dentistry, but on average, silver amalgam fillings cost $60 - $150 each. It's the cheapest way to get a filling. For comparison, composite fillings are roughly twice as expensive, weighing in an average price of $125 - $250.

If you're covered by dental insurance, plans usually cover 60 - 80% of the price of fillings.

Alternatively, gold fillings require a more costly material and skill from your dentist, making it the most expensive option for fillings.

What are the benefits of non-metal fillings over metal fillings?

The most obvious advantage of non-metal fillings is that they blend in with your teeth more than silver amalgam fillings.

Amalgam fillings can also corrode over time and may discolor the area where the filling meets the tooth. Don't be fooled by name and color: silver amalgams are made up of more than just silver. "Amalgam" means a mixture or blend - silver amalgam fillings are a mix of silver, tin, zinc, copper, and mercury. That last ingredient should alarm you because silver amalgam fillings are indeed about 50% mercury. Most oral health experts believe that this small amount of mercury is harmless but there are others who are concerned about the possible long-term effects.

Traditional silver amalgam fillings do not easily bond to teeth. To ensure that the fillings fit snugly and adhere to teeth, dentists prepare a pocket by drilling extra and removing some healthy tooth structure.

In addition, when you have a silver amalgam filling sitting near a gold filling, the two metals interact and your saliva can produce an uncomfortable electric current known as galvanic shock.
