Dental composites produce a natural-coloured restoration which blends nicely with the existing tooth, because of this, dental composites are sometimes called white fillings. The natural look that composite resin creates makes this material popular for fillings as well as the fabrication of crowns
. One of the drawbacks of using composite resin in fillings is they are not as strong as some other restorative materials and they are prone to staining like natural teeth.
Disadvantages of Amalgam Fillings
Although amalgam fillings may be less expensive, they have other disadvantages that go beyond cost. Over time, the colour of the amalgam silver can be seen through the tooth enamel. This gives your tooth a greyish black colour which is not aesthetically pleasing. Also, the edges of amalgam fillings can wear down, become weak or break. This breakdown of amalgam in the cavity, allows bacteria to become trapped between the amalgam and the tooth structure causing caries to form once more. Because amalgam fillings contain 50 percent mercury, over time, they may corrode, leak, and even stain your teeth and gums.
Advantages of Composite Restorations
There are many advantages to tooth-coloured composite restorations. Not only do they look natural, they form a tight bond with the surrounding tooth structure, minimizing food and bacteria from entering which could lead to dental caries, or cavities. When a substantial amount of the tooth structure is lost, composite fillings are beneficial in restoring the strength and structure of the tooth.
