Some types of dental fillings need to be often replaced because bacteria and food will form below the dental filling. Thus, before making your choice weigh the cons and pros for each type.

Types of Dental Fillings:

  1. Amalgam Dental Fillings:

    They contain about 50% of mercury and the remaining 50% is a mixture of silver, copper, zinc and tin. They are the cheapest type of dental fillings because the ingredients used are cheaper and the procedure also takes less time. They are also referred to as silver fillings, because of their grayish-silver color. They usually don’t bond well with the tooth and act like a wedge which fills an open space inside the tooth. Because of which, dentists have to remove some part of a healthy tooth material for creating a ledge which helps to keep the amalgam filling in place. Along with this, mercury content and color are the amalgam dental fillings’ drawbacks.

  2. Composite Resin Dental Fillings:

    They consist of glass and plastic. This type of filling appear more natural than other type such as amalgam dental fillings, because they match teeth color. Most people cannot say that the composite resin is not a part of natural tooth. They actually bond to the tooth, this allows the dentists to remove only the decayed part of the tooth. The drawbacks of composite resin dental fillings include less durability and possible shrinkage, which results in more frequent dental fillings replacement and it can also cause the bacterial growth resulting in further decay.

However, they are more prone to chipping and cracking than other materials. They need a certain amount of bulk for its durability, thus it is necessitate to remove some portion of healthy tooth material. They usually range in price, but cost a little more or usually the same as composite resin fillings. If more expensive materials are used, it may also cost as similar as gold fillings.

  5. Glass Ionomer Dental Fillings:

    These consist of a component of glass, acrylic and fluoroaluminosilicate. This material is most often used to fill small areas which are close to a tooth root or flat surfaces on the canines, bicuspids and incisors. Sometimes, this glass ionomer combines with the composite resin fillings for the hybrid dental filling, which offer advantages of both styles.
