What is a composite resin (white filling)?
Composite resin is a tooth-colored material made of plastic and fine glass particles. It was first introduced in the 1960s and has since been improved to be strong enough for both front and back teeth.
In addition to repairing decay, composites are also used for cosmetic improvements, such as reshaping teeth or enhancing their color.
How is a composite placed?
The dentist applies the composite in layers, using a specialized light to harden each layer. Once complete, the filling is shaped and polished to match the natural tooth.
How long does it take to place a composite?
Composite fillings typically take 10 to 20 minutes longer to place than traditional silver fillings, depending on the size and location of the cavity.
What is the cost?
Composite fillings generally cost more than silver fillings. Most insurance plans cover the cost up to the price of a silver filling, with the patient responsible for any difference.
What are the advantages of composites?
Composites offer excellent aesthetics, as they can be color-matched to your natural teeth. They also bond directly to the tooth, helping to strengthen the remaining structure and reduce the risk of breakage.
Additionally, composites help insulate the tooth from temperature changes.
What are the disadvantages?
Composite fillings may cost more and take longer to place. Some patients may experience temporary sensitivity after treatment.
They may also stain slightly over time from substances like coffee or tea and may wear faster than silver fillings in large restorations.
How long will a composite last?
Composite fillings typically last 7 to 10 years. Their lifespan is comparable to silver fillings in smaller cavities but may be shorter in larger restorations.
