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.

Starting college is one of life’s biggest transition moments, the first time many young people can truly say they’re on their own. Their freshman year can be both exhilarating and frightening.
The reason for this seeming dichotomy is that both exciting opportunities and harmful pitfalls abound in college life. One such pitfall that’s often overlooked involves dental health: it’s all too easy to neglect good habits and adopt bad ones. But while it may not seem as harmful as other dangers, inattention to your dental health could create consequences that plague you long after graduation.
But being diligent about dental care can help you avoid serious problems now and in the future. At the top of the list: brush and floss your teeth daily and continue seeing a dentist at least twice a year. Hopefully, your parents or guardians have trained you in these vital habits—and they’re definitely habits you should continue for the rest of your life.
Close in importance to good oral hygiene is a healthy diet. Besides eating primarily “natural” food—fresh fruits and vegetables and less-processed foods—you should also set limits on your sugar consumption. This carbohydrate is a primary food for disease-causing bacteria, so limiting as much as possible the sugar you eat to just meal times will lower your risk for tooth decay.
Another area in which you should tread wisely is alcohol consumption. Besides the obvious consequences of alcohol abuse, immoderate drinking can also cause dental problems. Alcohol (and smoking) tends to dry out the mouth, which can increase the levels of oral bacteria and in turn increase your risk of both tooth decay and periodontal (gum) disease.
Finally, avoid getting piercings involving the lips, mouth or tongue even if it’s the thing to do. Piercing hardware can chip teeth and contribute to the shrinking back of the gums (recession). And be sure you practice safe sex: unprotected sexual activity could expose you to viral infections that cause oral problems including cancer.
Your college years should be an exciting and memorable experience. By practicing these and other common sense dental habits, you’ll be sure to remember these years fondly.

People improve their smiles for a lot of reasons: to better their career prospects, to put some juice in their social lives or just to do something special for themselves. But you may have an even stronger reason: a once-in-a-lifetime event—maybe your wedding day—is coming up soon.
You have several options for transforming your smile for the big day—and some are even quite economical. Here are 4 affordable ways to make your smile beautiful for that forever moment.
Cleanings. While dental cleanings should already be part of your regular dental care, scheduling one right before a big event can do wonders for your smile. Not only can your hygienist remove any lingering dull and dingy plaque and tartar, but they can polish your teeth for a brighter shine. Remember, though: dental cleanings support your own hygiene efforts, they don't replace them. Your own daily practice of brushing and flossing will also help you maintain a beautiful smile.
Teeth Whitening. You can also get an extra boost of brightness with a tooth whitening procedure. Using a professional bleaching solution and other techniques, your dentist can lighten your smile to your tastes, from a more natural hue to dazzling white. The whitening effect, though, is temporary, so plan to see your dentist no more than a few weeks before your big day.
Bonding. Perhaps a tiny chip is all that stands between you and a knockout smile. Your dentist may be able to repair that and other minor defects by bonding tooth-colored materials to the chip site. These composite resin materials have the shine of enamel and can be color-blended to match your tooth's natural shade. Composite resins are also fairly rugged, although you should avoid biting down on hard foods or objects.
Veneers. Although more expensive than the previous options mentioned, veneers are still affordable compared to crowns or bridgework. Usually made of thin layers of dental porcelain, dentists bond veneers to the front of teeth to mask mild to moderate problems like heavy staining, disfiguration and minor gaps. But because veneers are custom-fabricated by a dental lab, you'll need to plan them with your dentist at least six months before your event. The resulting change to your smile, though, may well be worth the wait.

Is having good oral hygiene important to kissing? Who's better to answer that question than Vivica A. Fox? Among her other achievements, the versatile actress won the “Best Kiss” honor at the MTV Movie Awards, for a memorable scene with Will Smith in the 1996 blockbuster Independence Day. When Dear Doctor magazine asked her, Ms. Fox said that proper oral hygiene was indeed essential. Actually, she said:
"Ooooh, yes, yes, yes, Honey, 'cause Baby, if you kiss somebody with a dragon mouth, my God, it's the worst experience ever as an actor to try to act like you enjoy it!"
And even if you're not on stage, it's no fun to kiss someone whose oral hygiene isn't what it should be. So what's the best way to step up your game? Here's how Vivica does it:
“I visit my dentist every three months and get my teeth cleaned, I floss, I brush, I just spent two hundred bucks on an electronic toothbrush — I'm into dental hygiene for sure.”
Well, we might add that you don't need to spend tons of money on a toothbrush — after all, it's not the brush that keeps your mouth healthy, but the hand that holds it. And not everyone needs to come in as often every three months. But her tips are generally right on.
For proper at-home oral care, nothing beats brushing twice a day for two minutes each time, and flossing once a day. Brushing removes the sticky, bacteria-laden plaque that clings to your teeth and causes tooth decay and gum disease — not to mention malodorous breath. Don't forget to brush your tongue as well — it can also harbor those bad-breath bacteria.
While brushing is effective, it can't reach the tiny spaces in between teeth and under gums where plaque bacteria can hide. But floss can: That's what makes it so important to getting your mouth really clean.
Finally, regular professional checkups and cleanings are an essential part of good oral hygiene. Why? Because even the most dutiful brushing and flossing can't remove the hardened coating called tartar that eventually forms on tooth surfaces. Only a trained health care provider with the right dental tools can! And when you come in for a routine office visit, you'll also get a thorough checkup that can detect tooth decay, gum disease, and other threats to your oral health.
Bad breath isn't just a turn-off for kissing — It can indicate a possible problem in your mouth. So listen to what award-winning kisser Vivica Fox says: Paying attention to your oral hygiene can really pay off! For more information, contact us or schedule an appointment for a consultation.

For most dental procedures you’re usually back to your regular routine in no more than a day or two (or even hours) afterward. For the most part, the mouth heals rather quickly.
But there may still be a short period of discomfort after tooth extraction, gum surgery or similar invasive procedures. The good news is you will most likely have no need for strong narcotic painkillers — milder, over-the-counter pain relievers are usually sufficient to manage your discomfort.
The most common of these are known as non-steroidal anti-inflammatory drugs (NSAIDs). This group of pain relievers — which include aspirin and ibuprofen — block the release of substances in the body known as prostaglandins that stimulate inflammation that increases pain in damaged tissues. They’re much preferred for mild to moderate pain because they don’t have the side effects of steroids or narcotics like morphine or codeine. They also tend to be less costly than these other prescription drugs.
But while they’re reasonably safe, they can cause problems if you exceed the recommended dosage or use them for prolonged periods. Their blockage of certain chemicals reduces the clotting mechanism in blood leading to a blood-thinning effect. Not only will this increase bleeding, it can also damage the stomach lining and cause ulcers if used over a period of weeks. Improper dosage of NSAIDs has also been linked to miscarriages and repeat heart attacks, which is why they’re not recommended for use during pregnancy or with patients with a history of heart or intestinal problems.
But if taken as directed by your physician or dentist — usually no more than 2,400 milligrams a day and only for a few days — such side effects are quite rare. The benefit is much more common: about five hours of pain relief from a single dose for most people. With the help of ibuprofen or similar drugs, you’ll be on your feet after your dental work in no time.Â
