What are the Different Types of Dental Fillings?

Dental Fillings

There are several materials available for dental restorations at Dexter dental office including crowns and fillings, such as ceramic, glass ionomer, and composite resin. In this blog post learn more about different dental restorations.

Here are the different types of dental fillings:

Cast Gold

Gold is a durable and strong material that may be used to create crowns and fillings. On the other side, gold restorations are quite noticeable, thus gold is not the ideal choice if a natural appearance is preferred. The inherent strength and durability of gold are advantages to take into account for individuals who prefer the way gold restorations appear.


Amalgam is a metal alloy consisting of silver, copper, tin, and liquid mercury. Although it has been used for decades as a dental filler, its use is declining because of worries about mercury poisoning. The fact that amalgam has a silvery shine that contrasts with natural tooth tones and can make teeth appear discolored and unsightly is another reason why amalgam is less popular these days.


The shade of the composite fillings can be closely matched to the color of existing teeth. Composites are particularly well suited for use in front teeth or visible parts of teeth. Composite fillings micro-mechanically bond to tooth structure, providing further support. In addition to use as a filling material for decay, composite fillings can also be used to repair chipped, broken, or worn teeth.


Its strength, durability, and aesthetic appeal make dental ceramic a popular choice for treatments including veneers, crowns, and bridges. The advantage of ceramic is that it may be appropriately tinted to blend in with the existing teeth’s natural color. The fact that ceramic is more brittle than other materials is a drawback. Strong material is required for ceramic restorations on molars and incisors to withstand the force of chewing and biting. The drawback is that lighter, more aesthetically pleasing ceramics do not have the same natural look as this sturdy ceramic.

Glass ionomer is composed of a particular kind of glass and acrylic. Fillings below the gum line and in little infants are the most typical uses of this material (drilling is still necessary). Fluoride is released by glass ionomers, which may help shield the tooth from more decay. But compared to composite resin, this material is weaker and more prone to wear and breakage. Glass ionomer costs about the same as composite resin and often lasts five years or less. The most recent ones are comparable to composites and have an even longer lifespan when used in the right locations.

To create dental restorations that are both aesthetically pleasing and useful, selecting the appropriate material usually requires finding a balance between function and aesthetics.
