Composite restoration involves the application of a tooth-coloured plastic and glass mixture used to restore decayed teeth, or for cosmetic improvements of the smile by changing the colour of the teeth or reshaping disfigured or damaged teeth. It is most commonly used as a tooth coloured material for fillings in tooth cavities.
How is a Composite Placed?
The composite resin is prepared and then the dentist places it in layers, typically using a light specialised to cement harden each layer. When the resin is set in place, the dentist will shape the composite to fit the tooth. Then it can be polished to give a shiny, smooth finish and to prevent staining and early wear.
What are the advantages of Composites
The main advantage is the blend that can be achieved to create a colour nearly identical to that of the actual tooth. Composites bond to the natural tooth structure to support it, which helps to prevent breakage and insulate the tooth from excessive changes in temperature.
What are the disadvantages of Composites
Patient may experience sensitivity around the area of a new composite filling. Also, the colour of the composite can change if the patient drinks tea, coffee, wine or eats staining foods.
