What is a Composite Filling (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.
the composites used in our clinic are BPA Free composite materials Venus Diamond and also the composite of choice recommended by the IAOMT from Voco Admira. For build ups under crowns and for certain situations we use a non BPA Glasionomer cement material that is also BPA free called GCP a Glass carbomer filling material that is produced in Holland.
How is a composite placed?
Following preparation, the 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 dentist then polishes the composite to prevent staining and early wear.
What are the advantages of composites?
Aesthetics are the main advantage of composites, since dentists 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. The Filling is bonded to the tooth which gives additional strength to the tooth.
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.
