Having a cavity filled isn't what most people would look forward to, but it can be an essential part of dental care if decay has formed. composite fillings, beautifulFortunately, Dr. R. Brad Beasley, your dentist in Athens, AL, offers an option that makes fillings a little less unpleasant. At North Alabama Center for Cosmetic & General Dentistry, we use a composite material - a tooth-colored mixture of plastic and glass - to blend fillings in with the rest of the teeth. Here's are some reasons why composite fillings are the material of choice for both dentists and patients alike:

Attractive

If you've had any metallic fillings in the past, you know they can be fairly noticeable, even on your back teeth. They can show through the translucent enamel, giving most or all of the tooth a darkened appearance. Sometimes the metal particles can even make their way under the gums or soft tissues, leaving a blue-gray "tattoo" that, while harmless, can easily be mistaken for a malignancy.

With composite fillings from your Athens cosmetic dentist, your restored teeth will look totally natural. That's because the composite material comes in a variety of colors that Dr. Beasley carefully matches to each of his patients' teeth, giving you a personalized treatment that will strengthen your smile and improve your appearance.

Durable

When "white" fillings were first introduced, many dentists were still choosing amalgam as the filling material of choice for teeth used frequently for chewing. The material used for composite fillings wasn't quite as strong as metal and could break down due to constant pressure. Over time, the dental industry has reworked the structure of composite fillings that make them equally as durable as metal fillings. At North Alabama Center for Cosmetic and General Dentistry, you no longer have to choose between form and function when it comes to your fillings.

The next time you need a cavity filled, Dr. Beasley will be happy to use composite material to finish it off. Give us a call in Athens, AL if you have any further questions about composite fillings or any other cosmetic or general dentistry procedure!

ItsanArtDeterminingToothColorinCompositeResinRestorations

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.
