Tooth-colored fillings don't just restore teeth damaged by tooth decay but also provide several important advantages. Centralia, WA, dentists Drs. Steven Ash and Brian Roberts of Ash & Roberts, DDS explain how you benefit when you receive the fillings.
What are tooth-colored fillings?
Tooth-colored fillings blend in with the natural color of your teeth, making your fillings practically invisible. They're made of composite resin, a substance created by mixing durable plastic resin with powdered glass. Composite resin is available in a variety of shades to ensure that your dental work isn't noticeable.
What are the advantages of tooth-colored fillings?
Tooth-colored fillings not only look better but are also better for your teeth. When you have a cavity, some of the healthy tooth structure surrounding the decayed area must be removed in order to prepare the tooth for the filling. Although the filling process prevents decay from worsening and spreading, it also weakens your tooth slightly. Tooth-colored fillings only require the removal of a small amount of healthy tooth structure, unlike silver amalgam fillings. Removing the smallest amount of tooth structure possible is the key to strong teeth.
Composite resin doesn't just fill the hole in your tooth, but actually strengthens it. The material bonds to your tooth just seconds after it's applied in our Centralia office. Tooth-colored fillings also reduce the risk that your tooth will crack. Silver amalgam fillings constantly expand and contract when you eat or drink hot or cold foods and beverages. Unfortunately, the continual expansion and contraction can eventually cause a crack to form in your tooth. Cracks increase the risk of a broken tooth or a new cavity in the tooth. Because composite resin doesn't expand or contract when exposed to temperature changes, it's an excellent choice for fillings.
Tooth-colored fillings offer an excellent way to restore and protect your teeth. If you have a toothache or it's been a while since your last dental exam, call Centralia, WA, dentists Drs. Steven Ash and Brian Roberts of Ash & Roberts, DDS at (360) 736-8380 to schedule your appointment.
It takes a lot of skill, experience, talent and artistry to create tooth restorations that look so natural that no one can tell them apart from the originals. To do so requires understanding of the normal anatomy of a tooth as well as of the interactions of light and color.
How the anatomy of a tooth determines color
The color that we perceive when looking at a tooth results from the combined appearance of the tooth’s center core (dentin layer) and its covering enamel. Going from the outside in, the enamel is made of tightly packed crystals of calcium, which cause it to be one of the hardest substances naturally produced by animals. The crystals are also responsible for a tooth’s brilliance and translucence. The dentin is more like bone, a porous living tissue composed of microscopic tubes, interspersed with more calcium crystals. In the very center of the tooth is a central chamber containing the pulp and nerves.
Each of these layers has its own physical and optical properties. Since the enamel is translucent and the dentin is more opaque, most of the tooth’s color comes from the dentin and is transmitted through the enamel layer. Factors that affect this transmission include the thickness and age of the enamel as well as external tooth whitening.
If the enamel is more translucent, more of the color of the dentin shows through. If it is more opaque, the enamel absorbs and reflects light so that less color is visible and the enamel looks brighter.
The language of color composition and reflected light
Color means the whole spectrum in the rainbow. The spectrum is made up of the three primary colors — red, blue, and green. When all are combined, they create white light.
Hue refers to the brightest forms of the colors. The color we perceive depends on the dominant wavelength of light that is reflected by an object.
Value refers to a color’s lightness or darkness. A brighter color has a higher value.
Chroma is the amount of identifiable hue in a color. An achromatic color (without hue) appears gray.
Saturation is a measure of a color’s intensity.
This terminology of color is used not only by dentists and dental technicians, but also by a wide range of artists. It implies expertise and understanding of how colors work, how they vary and change and affect one another.
