Nothing grabs your attention like a sharp tooth pain, seemingly hitting you out of nowhere while you’re eating or drinking. But there is a reason for your sudden agony and the sooner you find it out, the better the outcome for your oral health.
To understand tooth sensitivity, we need to first look at the three layers of tooth anatomy. In the center is the pulp filled with blood vessels and nerve bundles: it’s completely covered by the next layer dentin, a soft tissue filled with microscopic tubules that transmit sensations like pressure or temperature to the pulp nerves.
The third layer is enamel, which completely covers the crown, the visible part of a tooth. Enamel protects the two innermost tooth layers from disease and also helps muffle sensations so the tooth’s nerves aren’t overwhelmed. The enamel stops at about the gum line; below it the gums provide similar protection and sensation shielding to the dentin of the tooth roots.
Problems occur, though, when the dentin below the gums becomes exposed, most commonly because of periodontal (gum) disease. This bacterial infection caused by dental plaque triggers inflammation, which over time can weaken gum tissues and cause them to detach and shrink back (or recede) from the teeth. This can leave the root area vulnerable to disease and the full brunt of environmental sensations that then travel to the nerves in the pulp.
Tooth decay can also create conditions that cause sensitivity. Decay begins when certain oral bacteria multiply and produce higher than normal levels of acid. The acid in turn dissolves the enamel’s mineral content to create holes (cavities) that expose the dentin. Not treated, the infection can eventually invade the pulp, putting the tooth in danger of being lost unless a root canal treatment is performed to remove the infection and seal the tooth from further infection.
So, if you begin experiencing a jolt of pain while eating or drinking hot or cold foods or beverages, see your dentist as soon as possible to diagnose and treat the underlying cause. And protect your teeth from dental disease by practicing daily brushing and flossing, as well as seeing your dentist for regular dental cleanings and checkups. Don’t ignore those sharp pains—your teeth may be trying to tell you something.

When the multi-platinum recording artist, songwriter and TV personality Jason Derulo was recently asked about his ideal woman, his answer covered a remarkably broad spectrum. "There’s no specific thing," he said, "so I think it’s unfair to say what my ‘type’ is." But it turns out that there is one thing the So You Think You Can Dance judge considers essential: A beautiful smile.
"I’m not into messy teeth," Derulo said. "If the grill has spaces and different colors, it’s not my vibe."
As it turns out, he may be on to something: A number of surveys have indicated that a bright, healthy smile is often the first thing people notice when meeting someone new. Yet many are reluctant to open up that big grin because they aren’t satisfied with the way their teeth look. If you’re one of them, consider this: Modern cosmetic dentistry offers a variety of ways to improve your smile — and it may be easier and more affordable than you think.
For example, if your smile isn’t as bright as you would like it to be, teeth whitening is an effective and economical way to lighten it up. If you opt for in-office treatments, you can expect a lightening effect of up to 10 shades in a single one-hour treatment! Or, you can achieve the same effect in a week or two with a take-home kit we can custom-make for you. Either way, you’ll be safe and comfortable being treated under the supervision of a dental professional — and the results can be expected to last for up to two years, or perhaps more.
If your teeth have minor spacing irregularities, small chips or cracks, it may be possible to repair them in a single office visit via cosmetic bonding. In this process, a liquid composite resin is applied to the teeth and cured (hardened) with a special light. This high-tech material, which comes in colors to match your teeth, can be built up in layers and shaped with dental instruments to create a pleasing, natural effect.
If your smile needs more than just a touch-up, dental veneers may be the answer. These wafer-thin coverings, placed right on top of your natural teeth, can be made in a variety of shapes and colors — from a natural pearly luster to a brilliant "Hollywood white." Custom-made veneers typically involve the removal of a few millimeters of tooth enamel, making them a permanent — and irreversible — treatment. However, by making teeth look more even, closing up spaces and providing dazzling whiteness, veneers just might give you the smile you’ve always wanted.

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.
