Christie Brinkley's world-famous smile has graced the covers of countless magazines for over 30 years. In fact, in her own words from an interview with Dear Doctor magazine, the supermodel said, “I think my smile was really my passport to success in the modeling industry.” And while most of her smile's appeal comes naturally, Christie does give it a boost with good oral hygiene, regular dental checkups and tooth whitening. As Christie says, “When it comes to teeth, keep it as natural as possible. Do not go overboard on whitening. You want your teeth to compliment your faceÃ¢Â€Â¦your friends should not be required to wear sunglasses when you smile!”
Aside from some potential minor side effects such as tooth sensitivity, whitening teeth through bleaching is a relatively inexpensive way to brighten your smile conservatively and successfully. There are three common methods, as described below:
- An external or vital approach where “vital” (living) teeth are bleached through direct contact to the tooth's surface.
- An internal or non-vital approach where the tooth is whitened from the inside during a root canal treatment.
- A combination approach in which both internal and external bleaching techniques are used.
But what causes teeth to become discolored?
Tooth discoloration can be caused by a traumatic blow to your teeth resulting in nerve tissue (pulp) death. However, there can be many other causes: consuming or using products that stain the teeth such as coffee, tea, cola, tobacco products and red wine, to name just a few. Aging is another factor, as it results in changes in the mineral structure of the tooth as the enamel, the outermost layer, loses its beautiful and youthful translucency. Other causes include exposure to high levels of fluoride; tetracycline, an antibiotic, administered during childhood; inherited developmental disorders and jaundice in childhood; and tooth decay.
The good news is that we routinely brighten smiles through tooth whitening. To learn more about brightening your smile, continue reading the Dear Doctor magazine article “Teeth Whitening.” Or if you are ready to have your teeth professionally whitened, contact us today to schedule an appointment so that we can conduct a thorough examination and discuss your whitening treatment options.

Here's an interesting tidbit of information on Wheel of Fortune host Vanna White: like many people, she grinds her teeth at night. In a detailed interview with Dear Doctor magazine, Vanna explained how she had to replace a filling in a back tooth several times because of her grinding habit. Eventually, she had her dentist make her a nightguard to protect her famous smile.
“I really try to sleep with it every night,” Vanna told the magazine. “I try to keep it on my nightstand so when I go to bed, I remember to put it in. Or I will put it by my toothbrush so I can put it in after brushing my teeth at night.”
The habit of teeth grinding or clenching is often associated with stress and/or sleep deprivation. It is referred to as “parafunctional” (“para” – outside, “function” – normal), meaning it can generate biting forces well outside the normal range — perhaps 10 times normal. This excessive force can affect many areas of the oral system. Teeth may become worn, chipped or loose; jaw joints or muscles can go into spasm; and some grinders (or “bruxers” as they are also called) may even experience discomfort of the head, ears, neck or back. Many times, a person with a grinding habit does not become aware of it until it is pointed out by a sleep partner or dental professional.
Like Vanna White's dentist, we often recommend a nightguard to those with nocturnal bruxing habits. It is made of a very thin, wear-resistant plastic that fits over the biting surfaces of the upper teeth only. The lower teeth are then free to glide or skate over the guard, which prevents them from biting into the upper teeth. Some people wear their guards during the day if they tend to clench their teeth when under stress.

On the day when braces come off, most people feel that their orthodontic treatment is over. When they are then asked to wear retainers, they may wonder what this additional requirement will accomplish. Wasn't the work of moving their teeth to desired positions already completed? To understand the answer to this question, you need to understand how orthodontics works.
How does orthodontic treatment remodel your smile?
Although they give the appearance of being stable and unmoving, teeth and their surrounding structures (gums, jawbones, and ligaments) are living tissues and are actually in a constant state of change.
Teeth are rooted in bone and are attached by a fibrous tissue called the periodontal ligament (from peri meaning around and odont meaning tooth). One side of the ligament attaches to the cementum (part of the tooth's root) and the other side is attached to the bone, with the tooth suspended in between.
These tissues are constantly remodeling themselves, but pressure from the lips and cheeks on one side and from the tongue on the other create a balance that keeps the teeth suspended in the same location. When mild forces are placed on the teeth, such as the forces from the wires used in orthodontic treatment, the tissues slowly adapt and rebuild, resulting in a new position for the teeth.
What are retainers?
Orthodontic retainers are devices usually made of a clear plastic section that is fitted to the roof of the mouth, with thin wires that fit over the teeth.
What is the purpose of retainers?
The remodeling process keeps going after the orthodontic treatment stops, so time is needed for the teeth to reach a new balanced state. The retainer stabilizes them in their new position so that bone and ligament can reform around the teeth and hold them there. This works well for adolescents, whose jaws are in a state of growth, but adults may need outside assistance to stabilize their teeth for a longer time. They may be asked to wear retainers indefinitely to make sure their teeth do not move from their new positions.
What happens if you don't wear your retainers?
If you don't wear your retainers, your teeth are likely to return to the positions they had prior to your orthodontic treatment. This can happen fairly rapidly, underscoring the importance of wearing retainers as instructed.
What are the different types of retainers?
Most retainers are removable devices as described above. For people who require long-term use of retainers, thin retainer wires can be bonded to the inside surfaces of their front teeth. Such wires are usually left in place for several years, relieving them of the need to remove and replace their retainers.

Dental implants are replacements for missing teeth. They are very stable and can be made to look as good as or better than the teeth they replace. How do we do it? Here are seven frequently asked questions.
What are the parts of a dental implant?
The implant consists of a root, usually made of a titanium alloy, which extends below the gum tissue into the bone; and a crown, which emerges from the gum and resembles the crown of the original tooth.
Why is a dental implant so stable?
Titanium has a property of fusing with the bone of the jaw, so that it actually becomes part of the bony structure. The new implant's stability depends on having the needed volume of bone and gum tissue in the right position to anchor the implant.
How can you make sure I have enough bone?
When a tooth is lost, the bone in which it was anchored will resorb or melt away if care is not taken. It is important to minimize trauma during tooth removal to preserve bone tissue. If tissue has been lost it can be built up by bone grafting techniques.
What factors make a crown on an implant look real?
How real the crown looks depends on its shape, particularly as it emerges through the gum tissues, its color and its position relative to the teeth around it.
What is the emergence profile?
This term refers to the way the crown emerges through the gum tissue. It involves both the shape of the implant and how far it is placed into the gum and bone tissues.
How do you match the color of the crown?
We analyze your tooth color using shade guides and/or photography to provide the dental lab with as much information as possible to create the best color match. This is part of the artistry of reconstructive dentistry.
How will my gums look with my dental implant in place?
When people use the word “gums” they are often referring to the small pink triangles of tissue that fill in the spaces between teeth, called “papillae.” An implant must be placed at the correct distance from adjacent teeth and at the correct depth below the gum tissue for natural looking papillae to form.
You can see that success in matching of color, shape, and location of an implant is not simple and depends on the skill, artistry, and experience of your dental team.
