Tooth-Colored Fillings Lincoln

What Material Do Tooth-Colored Fillings Use?

Silver fillings consist of different metals, including tin, copper, mercury, gold, and other alloys. In stark contrast, tooth-colored fillings use composite resin, which combines glass and plastic compounds to form a putty-like substance. Since composite resin is more malleable, dentists can create a more effective seal in the damaged portion of the tooth while reducing the removal of natural tooth structure. Buffing teeth down to accommodate a dental filling is typical for silver fillings; however, this is typically not the case when using tooth-colored alternatives.

The Benefits of Composite Resin vs. Amalgam

One of the most significant drawbacks of amalgam is its response to hot and cold stimuli. When metal is exposed to extreme temperatures, it begins to expand and then contract into its original state after the stimulus is removed. This regular expansion causes the filling to act as a wedge inside the tooth and only breaks it apart more quickly. This is often why dentists will replace it with a tooth-colored alternative. Composite resin does not respond to stimuli in this way, making it ideal for use as a filling material.

Additionally, composite resin can be shaded to blend in exactly with your existing tooth, reducing the risk of it appearing in your smile. It doesn’t reflect light in the same way as silver, either, making it ideal for filling visible cavities.

How are Tooth-Colored Fillings Placed?

Placing a filling typically only takes one appointment. After examining your tooth, the dentist will clean it of any decay or debris before applying a mild etching material directly to the tooth. This makes the surface more porous, allowing the resin to bond more effectively. After placing and molding the filling inside your cavity, the dentist will bond the material instantly via a curing light. Once hardened, they can make mild adjustments to the filling as needed. With proper care, your restoration should last at least 10 years before needing to be replaced!

Making Your Restorations Last

To ensure your restoration gets as much mileage as possible, it’s essential to practice daily oral care, schedule checkups and cleanings once every six months at our dental office, and avoid using your teeth to perform tasks that are really suited for a tool. Do not chew on inedible or extremely hard objects, as this can prematurely wear down your restoration and damage your natural enamel.
