Radiographic (x-ray) images are an indispensible diagnostic tool in dentistry. One of the most routine and useful types of x-rays dentists take is the so-called bitewing. Here are some things you may want to know about this common diagnostic procedure.
What are bitewing x-rays?
Bitewings reveal the presence and extent of decay in the back teeth, specifically in areas where adjacent teeth touch each other. Unlike other areas of the teeth, these contacting surfaces between adjacent teeth can’t be examined visually. Bitewings can also show areas of bone loss around teeth — a sign of periodontal disease; however, they are not taken for that purpose because bitewings will not show the complete root surface that is surrounded by bone.
Why are they called that?
The name “bitewing” refers to how the film — or sensor, in the case of a digital x-ray — is positioned in the mouth: The patient bites down on a little tab or wing that holds the apparatus in place.
How often do I need them?
This is determined on a case-by-case basis, with the goal of not exposing you to any more radiation than necessary — even the minimal amount found in a series of bitewing x-rays. Your individual susceptibility to caries (tooth decay) and personal dental history will play a major role in determining how frequently you need radiographic examination — and, for that matter, how often you need to come in for routine cleanings and exams.
Are they safe?
The safety of bitewing x-rays is best illustrated with a comparison to the regular daily radiation exposure we get every day from environmental sources, which is about 0.01 millisieverts — the unit of measure we use for radiation. A series of 4 bitewing x-rays exposes you to 0.004 millisieverts of radiation — less than half of the daily exposure. Undetected tooth decay, which can spread quickly through the softer inner layers of teeth, is considered much more dangerous!
If a bitewing x-ray shows that there is tooth decay, what happens next?
If the cavity is very small, we may be able to treat it during the same appointment. If not, we will make a separate appointment to make sure it is taken care of promptly. The sooner tooth decay is treated, the better!
Though you don't like to admit it, you don't floss very often. Oh sure, you know it's important to remove the film of bacteria and food particles called plaque that builds up between and on your teeth. And you know you should do it every day.
It's just that, well… you're not very good at using dental floss.
While it's effective, dental floss takes some technique to hold it with your fingers and work it between your teeth. It can be hard for people to get the hang of it — and some aren't physically able or have obstacles like braces that make it harder.
There is a solution: an oral irrigator. Available for home use for decades, these devices deliver pulsating water at high pressure through a handheld device that looks like a power toothbrush. The water flows through a special tip to loosen and flush out plaque from between teeth.
You may have encountered oral irrigation during dental visits. They're a regular part of dental cleanings especially for treatment of periodontal (gum) disease. Because gum tissue weakened by disease may gradually separate from the teeth, large voids or gaps called periodontal pockets can form. These pockets can become further infected and accumulate plaque and calculus (hardened plaque deposits) that can also extend to the roots. Oral irrigation is a way to remove much of the plaque from these hard to reach places.
Oral irrigators have also proven effective for orthodontic patients whose brace hardware inhibits regular dental floss. A 2008 study, for example, found orthodontic patients were able to remove five times as much plaque with an oral irrigator as those who used only a manual toothbrush.
If you're simply looking for an effective alternative to dental floss, an oral irrigator is a good choice. We can help choose the right model for you and give you tips on using it. Your goal is the same as if you were using dental floss — remove the plaque between your teeth to keep disease at bay and your smile healthy.

We've all had them — tiny sores that pop up seemingly out of nowhere under the tongue or the inside of the cheek. They're named aphthous ulcers, but are more commonly known as canker sores. For some people, they can be a recurring irritation.
Round with a yellow-gray center surrounded by reddened skin, aphthous ulcers seem to coincide with periods of anxiety or stress, or as a result of some minor trauma. Many people will feel a tingling or painful sensation a few hours or days before the ulcers appear. Once they appear they usually persist for a week to ten days before finally drying and healing. In the meantime they can be painful, especially while eating or drinking.
One form known as recurrent aphthous stomatitis (RAS) affects about a quarter of the population with outbreaks of multiple ulcers that occur regularly. RAS ulcers are usually one centimeter or more in size — the larger the sore the more painful they tend to be.
There are ways to ease the discomfort of an ulcer outbreak and help hasten their healing. A number of over-the-counter products can be used in minor cases to numb the area temporarily and cover it to facilitate healing. We can also apply steroids or inject other medications for more severe cases. You may also find curbing your eating of certain foods like tomato sauce, citrus or spicy dishes can help.
For the most part aphthous ulcers aren't dangerous. In some situations, though, you should seek dental or medical evaluation: a sore that doesn't heal within two weeks; increases in severity, frequency or duration of ulcers; or when you don't seem to ever be without an ulcer in your mouth. We may need to perform tests, including tissue biopsy, to make sure there aren't any underlying systemic conditions causing the ulcers.
More than likely, though, you'll only need relief from the aggravation caused by aphthous ulcers. Among the many remedies, there's one right for you.

What's an actor's most important feature? According to Vivica A. Fox, whose most recent big-screen role was in Independence Day: Resurgence, it's what you see right up front.
"On screen, your smile and your eyes are the most inviting things that bring the audience in" she said. "Especially if you play the hot chick."
But like lots of people, Vivica reached a point where she felt her smile needed a little help in order to look its best. That's when she turned to a popular cosmetic dental treatment.
"I got veneers years ago," Ms. Fox told Dear Doctor magazine in a recent interview, "just because I had some gapping that probably only I noticed."
What exactly are dental veneers? Essentially, they are thin shells of lustrous porcelain that are permanently attached to the front surfaces of the teeth. Tough, lifelike and stain-resistant, they can cover up a number of defects in your smile — including stains, chips, cracks, and even minor spacing irregularities like the ones Vivica had.
Veneers have become the treatment of choice for Hollywood celebs — and lots of regular folks too — for many reasons. Unlike some treatments that can take many months, it takes just a few appointments to have veneers placed on your teeth. Because they are custom made just for you, they allow you to decide how bright you want your smile to be: anywhere from a natural pearly hue to a brilliant "Hollywood white." Best of all, they are easy to maintain, and can last for many years with only routine care.
To place traditional veneers, it's necessary to prepare the tooth by removing a small amount (a millimeter or two) of its enamel surface. This keeps it from feeling too big — but it also means the treatment can't be reversed, so once you get veneers, you'll always have them. In certain situations, "no-prep" or minimal-prep veneers, which require little or no removal of tooth enamel, may be an option for some people.
Veneers aren't the only way to create a better smile: Teeth whitening, crowns or orthodontic work may also be an alternative. But for many, veneers are the preferred option. What does Vivica think of hers?
"I love my veneers!" she declared, noting that they have held up well for over a decade.
In the quest for the ideal diet, people often stress over one particular food group: carbohydrates. And for good reason—some carbohydrates have been linked to chronic inflammation, a contributing factor in many diseases. One such condition in particular, periodontal (gum) disease, could permanently damage your dental health.
But before you throw all the carbs out of your diet, let’s take a closer look at them. Not all carbs are the same or contribute to inflammation to the same degree.
Carbohydrates are organic compounds existing in living tissues. In foods, the most prevalent of these are sugars and starches that break down during digestion into the simple sugar glucose, which the cells in an organism use for energy.
But not all carb-based foods digest at the same rate, measured along a scale called the glycemic index. High glycemic foods like sugar, baked goods or potatoes digest quickly and can rapidly increase the glucose levels in the blood (blood sugar). This sudden glucose spike then triggers an insulin surge from the pancreas to restore the level to normal. This process in turn can cause inflammation.
On the other end of the glycemic index are complex or unrefined carbohydrates that digest much more slowly, and don’t quickly elevate blood sugar like simple carbs. In fact, nutritional studies consistently show carbohydrates in most vegetables, greens, beans or whole grains may actually decrease inflammation.
Inflammation is also a primary factor in gum disease, caused by a bacterial infection in the gums. Chronic inflammation damages the gums’ attachment with the teeth and can contribute to eventual tooth loss. And if your body already has an overactive inflammatory response due to your diet, you could be even more susceptible to gum disease.
A change in your diet in relation to carbs could help reduce this risk. Eat less sugar, white flour, rice and potatoes and more complex carbs like fresh vegetables and fruits. For even more protection include foods rich in Omega-3 fatty acids (like certain fish and nuts) and less Omega 6 foods (fried food or pastries, or chips, for example). And don’t forget your antioxidants, vitamins and minerals.
Eating fewer simple carbs and more complex carbs will help reduce inflammation in the body. And that’s a good thing for your gums.
