What is a Composite Resin (White Filling)?
A composite filling is a tooth-colored plastic and glass mixture used to restore decayed teeth. Composites are also used for cosmetic improvements of the smile by changing the color of the teeth or reshaping disfigured teeth. They can also be used to close gaps or part of mini smile makeover using boning technique.
How is a composite placed?
Following preparation, the cosmetic dentist places the composite in layers, typically using a light specialized to harden each layer. When the process is finished, the dentist will shape the composite to fit the tooth. The cosmetic dentist then polishes the composite to prevent staining and early wear.
What is the cost?
Prices vary, but composites can cost up to two times the price of a silver filling. Most dental insurance plans cover the cost of the composite up to the price of a silver filling, with the patient paying the difference. As composites continue to improve, insurance companies are more likely to increase their coverage of composites.
What are the advantages of composites?
Aesthetics are the main advantage of composites, since cosmetic dentist can blend shades to create a color nearly identical to that of the actual tooth. Composites bond to the tooth to support the remaining tooth structure, which helps to prevent breakage and insulate the tooth from excessive temperature changes. Composite is mercury-free or has no other metals.
What are the disadvantages?
After receiving a composite, a patient may experience postoperative sensitivity. Also, the shade of the composite can change slightly if the patient drinks tea, coffee or other staining foods. The cosmetic dentist can put a clear plastic coating over the composite to prevent the color from changing if a patient is particularly concerned about tooth color. Composites tend to wear out sooner than silver fillings in larger cavities, although they hold up as well in small cavities…read more
With large cavities, we recommend the use of cosmetic onlays or cosmetic crowns to provide stronger long lasting restoration.
