Tooth Filling Material

If your dentist detects cavities in your teeth, one of the dental treatments that may be suggested may include having the rotten part of the tooth removed and then the vacated area filled with a dental material called tooth fillings.

There are different types of tooth filling materials that are available to help restore your teeth. Each one has advantages and disadvantages and differs from the other types of materials concerning aesthetics, durability, expense, and strength. The type of tooth filling material your dentist may recommend will depend on these factors in addition to which of your teeth have to be treated and the type of damage that has to be repaired.

Types of Tooth Filling Materials

Composite Resin Fillings

Composite resins are made of a combination of finely ground glass particles and plastic and can last you for at least five years. Because they can be matched to the exact hue of your teeth, they are ideal for front teeth, any visible portion of a tooth that requires small or large fillings and inlays. They can be bonded directly onto your teeth making the tooth stronger than it would be with other types of fillings. Depending on whether you require direct or indirect filings, having composite resin fillings installed may take more than one visit to the dentist office.

Gold Fillings

Gold fillings are one of the more expensive types of fillings; however, they are highly durable, do not corrode and can last at least 15 years. They are made of primarily gold and a mixture of other metals. Gold fillings are used for crowns, onlays, and inlays and having them installed requires at least two visits to the dentist office.

Amalgam Fillings

Amalgam fillings silver-toned fillings that are composed of almost 50 percent of mercury with the remaining portions comprised of a mixture of other metals, including tin, copper, silver, and tin. These non-bonded and durable fillings can be used to restore your back teeth and can last for more than ten years. However, they cannot be color-matched to your teeth and tend to corrode with time, resulting in discoloration in the areas where your tooth is in contact with the filling.

Ceramics Fillings

Usually composed of porcelain, ceramic fillings are used to restore veneers, crowns, inlays, onlays, orthodontic brackets, and implants. They are made to have the same coloring as teeth and can last you for over seven years. If it is necessary for you to have a ceramic inlay or onlay, the affected tooth will have to be reduced in size to make the filling sizable enough so that it will not break.

Glass Ionomer Fillings

This type of filling is composed of acrylic and fluoroaluminosilicate, a material used to make glass. Glass ionomer fillings may be recommended if you have decaying tooth material in your front teeth or below your gum line in the roots of your teeth. The fillings release fluoride, which can make the tooth stronger and more resistant to further decay. They can last you for at least five years but are weaker than composite resin fillings.
