What is a Composite Resin (white) filling?

A composite resin is a tooth-colored plastic mixture filled with glass beads (silicon dioxide). This material is used for restoring decay, as well as for some cosmetic improvements of the smile. The color or shape of a disfigured tooth can be changed.

How is a composite placed?

First the decay is removed. Then, Dr. Ramirez places the composite in thin layers. He uses a special Plasma Arc Light to harden each layer. The composite is shaped and then polished to prevent staining and early wear.

How long does It take to place a composite?

Placement time depends on the size and location of the cavity. Plan on at least 45-60 minutes per tooth.

What is the cost?

Prices vary, but composites average 1 ½ - 2 times the price of a silver filling. Most dental insurance plans cover the cost of the composite up to the price of a mercury/silver filling, with you paying the difference.

Insurance companies pay the lowest alternative treatment. Whatever is cheapest is how they usually pay!

Advantages:

Composites bond to the tooth to support the remaining tooth structure, which helps to prevent breakage and insulate the tooth from excessive temperature changes.

Shades can be blended to create a color nearly identical to that of the actual tooth.

Disadvantages:

• Higher cost
• Extra placement time
• Possible post-operative sensitivity.
• The shade of the composite can change slightly if you drink tea, coffee or other staining foods.

Although they hold up well in small cavities, they are probably not the best recommendation for large cavities in back teeth. Inlay, onlay and crown restorations are better suited here.

Generally, Dr. Ramirez chooses to use porcelain onlay or crown restorations on back teeth because they are a superior material and have several structural and bonding advantages over regular composite or mercury-silver fillings. They last longer as long as your own natural tooth remains sound.

How long will a composite last?

According to reports, at least 5 years and possibly up to ten.
