While the cost of a composite may vary, they cost about one and a half to two times the average cost of a silver filling. Luckily, most dental insurance plans will cover the price of the composite up to that of a silver filling, but with the patient being liable for the difference. But as composites continue improving, insurance companies will most likely double their coverage of composites.
Advantages of composites
The major advantage is aesthetics, as dentists are able to blend shades to make a color that closely resembles the real tooth.
Composites work by bonding to the tooth in order to support the rest of the tooth structure. This not only prevents breakage, but also insulates the tooth from extreme temperature variations.
Disadvantages of composites
Following the placement of a composite, some patients experience post-operative sensitivity. Additionally, the composite’s shade may change slightly on drinking coffee, tea, or taking any other staining foods. The dentist may place a clear plastic coating on the composite to prevent it from changing colour, especially if the patient is particularly concerned about his or her tooth colour. In larger cavities, composites tend to wear out faster than silver fillings, especially in larger cavities, despite holding up as well in much smaller cavities.
