On the big screen, Australian-born actress Margot Robbie may be best known for playing devil-may-care anti-heroes—like Suicide Squad member Harley Quinn and notorious figure skater Tonya Harding. But recently, a discussion of her role in Peter Rabbit proved that in real life, she’s making healthier choices. When asked whether it was hard to voice a character with a speech impediment, she revealed that she wears retainers in her mouth at night, which gives her a noticeable lisp.
“I actually have two retainers,” she explained, “one for my bottom teeth which is for grinding my teeth, and one for my top teeth which is just so my teeth don't move.”
Clearly Robbie is serious about protecting her dazzling smile. And she has good reasons for wearing both of those retainers. So first, let’s talk about retainers for teeth grinding.
Also called bruxism, teeth grinding affects around 10 percent of adults at one time or another, and is often associated with stress. If you wake up with headaches, sore teeth or irritated gums, or your sleeping partner complains of grinding noises at night, you may be suffering from nighttime teeth grinding without even being aware of it.
A type of retainer called an occlusal guard is frequently recommended to alleviate the symptoms of bruxism. Typically made of plastic, this appliance fits comfortably over your teeth and prevents them from being damaged when they rub against each other. In combination with stress reduction techniques and other conservative treatments, it’s often the best way to manage teeth grinding.
Orthodontic retainers are also well-established treatment devices. While appliances like braces or aligners cause teeth to move into better positions, retainers are designed to keep teeth from moving—helping them to stay in those positions. After active orthodontic treatment, a period of retention is needed to allow the bite to stabilize. Otherwise, the teeth can drift right back to their old locations, undoing the time and effort of orthodontic treatment.
So Robbie has the right idea there too. However, for those who don’t relish the idea of wearing a plastic appliance, it’s often possible to bond a wire retainer to the back surfaces of the teeth, where it’s invisible. No matter which kind you choose, wearing a retainer can help keep your smile looking great for many years to come.

For best results in cleaning your teeth of disease-causing plaque you need both the power of brushing open teeth surfaces and flossing in between them. But you may be wondering: should you perform one task before the other?
In general terms, no—there’s no solid evidence that flossing is better before brushing, or vice-versa. But that being said we do recognize each way has its own advantages.
If you floss before brushing, it’s possible you could loosen plaque that can then be easily brushed away when you perform your second hygiene task. Flossing first can also reveal areas that need a bit more attention from brushing if you suddenly encounter heavy particle debris or you notice a little bit of blood on the floss. And, by flossing first you may be able to clear away plaque from your tooth enamel so that it can more readily absorb the fluoride in toothpaste.
One last thing about flossing first: if it’s your least favorite task of the two and you’re of the “Do the Unpleasant Thing First” philosophy, you may want to perform it before brushing. You’re less likely to skip it if you’ve already brushed.
On the other hand, flossing first could get you into the middle of a lot sticky plaque that can gum up your floss. Brushing first removes a good portion of plaque, which can then make flossing a little easier. With the bulk of the plaque gone by the time you floss, you’ll not only avoid a sticky mess on your floss you’ll also have less chance of simply moving the plaque around with the floss if there’s a large mass of it present.
It really comes down to which way you prefer. So, brush first, floss last or vice-versa—but do perform both tasks. The one-two punch of these important hygiene habits will greatly increase your chances for maintaining a healthy mouth.
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.

Cancer treatment can consume all of your focus to the exclusion of other health issues. But these other issues still need attention, especially how treating cancer could affect other parts of your body. That definitely includes your teeth and gums.
Treatments like radiation or chemotherapy eradicate cancer cells disrupting their growth. Unfortunately, they may do the same to benign cells — “collateral damage,” so to speak. This could cause a ripple effect throughout the body, including in the mouth. Radiation, for example, could damage the salivary glands and result in reduced salivary flow. Because saliva neutralizes acid and diminishes bacterial growth, your risk for tooth decay as well as periodontal (gum) disease could increase.
While you may be able to recover from reduced salivary flow after treatment, your health could suffer in the meantime, even to the point of tooth and bone loss. Fortunately, there are some things we can do before and during your treatment.
If you can, have any necessary dental work performed well before you begin cancer treatment. You’ll be more resistant to side effects if you can start treatment with as healthy a mouth as possible.
Keep up your regular dental visits if at all possible, or see us if you begin seeing signs of dental disease. By staying on schedule, we’ll have a better chance of detecting and treating problems before they advance too far; we may also be able to provide preventive measures like topical fluoride applications to help keep your teeth resistant to disease. If you need more extensive treatment like tooth extraction or surgery we may need to coordinate with your cancer treatment provider.
Above all, continue to practice daily brushing and flossing to remove plaque, the main cause of dental disease. Drink plenty of water or take substances that boost salivation. And be sure to eat a nutritious diet while also reducing or eliminating tobacco or alcohol from your lifestyle.
Taking these steps will help protect your teeth and gums during cancer treatment. As a result, you have a better chance for maintaining your dental health during this critical time in your life.

Fans of the legendary rock band Steely Dan received some sad news a few months ago: Co-founder Walter Becker died unexpectedly at the age of 67. The cause of his death was an aggressive form of esophageal cancer. This disease, which is related to oral cancer, may not get as much attention as some others. Yet Becker's name is the latest addition to the list of well-known people whose lives it has cut short—including actor Humphrey Bogart, writer Christopher Hitchens, and TV personality Richard Dawson.
As its name implies, esophageal cancer affects the esophagus: the long, hollow tube that joins the throat to the stomach. Solid and liquid foods taken into the mouth pass through this tube on their way through the digestive system. Worldwide, it is the sixth most common cause of cancer deaths.
Like oral cancer, esophageal cancer generally does not produce obvious symptoms in its early stages. As a result, by the time these diseases are discovered, both types of cancer are most often in their later stages, and often prove difficult to treat successfully. Another similarity is that dentists can play an important role in oral and esophageal cancer detection.
Many people see dentists more often than any other health care professionals—at recommended twice-yearly checkups, for example. During routine examinations, we check the mouth, tongue, neck and throat for possible signs of oral cancer. These may include lumps, swellings, discolorations, and other abnormalities—which, fortunately, are most often harmless. Other symptoms, including persistent coughing or hoarseness, difficulty swallowing, and unexplained weight loss, are common to both oral and esophageal cancer. Chest pain, worsening heartburn or indigestion and gastroesophageal reflux disease (GERD) can also alert us to the possibility of esophageal cancer.
Cancer may be a scary subject—but early detection and treatment can offer many people the best possible outcome. If you have questions about oral or esophageal cancer, call our office or schedule a consultation. You can learn more in the Dear Doctor magazine article “Oral Cancer.”
