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.

The holidays are a season for giving. At this time of year, lots of us spend hours rushing around, looking for the perfect gifts for people we care about. But sometimes, amidst all the hustle and bustle, it doesn’t hurt to step back and think about yourself a little. If a better-looking smile has been on your list but you haven’t taken the first steps, the holiday season might be the right time to give yourself a gift.
Many smile problems, like discolored, chipped or uneven teeth, can be resolved with veneers—wafer-thin porcelain shells that cover the front surfaces of teeth. Veneers are custom-made just for you: They can have a pearly luster to match your existing teeth, or be Hollywood-white for a dazzling red-carpet smile. In just a few visits to the dental office, you can have the smile you’ve always wanted—and a whole new look for the New Year.
If damaged or missing teeth are what’s bothering you, you’ll be happy to know that there are lots of good options for replacing them. If the tooth’s roots are still in good shape, a crown or cap could be the answer. This is a sturdy replacement for the entire visible part of the tooth that not only looks great, but also functions well in your bite—and can last for years to come.
If teeth are missing or can’t be saved, we offer several options for replacement, including fixed (non-removable) bridgework and dental implants. A tried-and-true method for replacing one or more missing teeth, bridges are firmly supported by healthy teeth next to the gap in your smile. These teeth must be prepared to receive the bridge by having some of the tooth’s surface removed.
Dental implants are today’s premier option for tooth replacement. In this high-tech system, a root-like titanium insert, placed directly into the bone beneath the gum, forms a solid anchorage for the visible part of the replacement tooth. Implants look and feel completely natural, and can last for many years. Plus, they don’t require any work to be done on nearby teeth.
What kind of smile makeover is right for you? Just ask us! We will be happy to take a look at your smile and recommend a treatment plan. And in this season of generosity, there’s no better gift you can give yourself than a bright new smile.
