Growing up with a dentist stepdad, Cheryl Burke of Dancing with the Stars heard a lot over the years about the importance of good oral hygiene — in particular, the benefits of using dental floss.
“My dad would say, ‘make sure you floss,’ but I never really listened to him. I was very, very stubborn,” Cheryl told Dear Doctor magazine recently in an exclusive interview. Cheryl admits this stubbornness took its toll, in the form of tooth decay. “I definitely had my share of cavities,” Cheryl recalled.
Cavities can form when food particles, particularly sugar and carbohydrates, are not effectively cleaned from the spaces between teeth. These particles are then broken down by bacteria naturally present in the mouth, resulting in the production of acids that attack the tooth enamel.
When she reached her twenties, Cheryl decided she really needed to step up her oral hygiene and cultivate an asset so important to a professional dancer: a beautiful smile. And once she did, cavities became a distant memory.
“I think when you do floss frequently, it helps to reduce the chances of getting cavities,” Cheryl said. “It took me a while to figure it out.” Now Cheryl flosses after every meal. “I carry floss with me wherever I go. I have no shame busting out my floss in the middle of a restaurant!” She declared.
Dental decay is actually a worldwide epidemic, especially among kids. Untreated, it can lead to pain, tooth loss, and, because it is an infectious disease, it may even have more serious systemic (whole body) health consequences. The good thing is that it is entirely preventable through good oral hygiene at home and regular professional cleanings here at the office.

The CAT scan is a relatively recent technique in dentistry, used to get an image of what’s happening deep within your jaws. You may be wondering what a CAT scan tells us that a conventional x-ray picture does not, and whether it is worth the extra expense to get one. And how does a CAT scan compare with a conventional x-ray in terms of radiation exposure?
CAT stands for “computer assisted tomography.” Often it’s just called a CT scan, for “computerized tomography.” The word “tomography” comes from roots meaning “slice” and “write.” Tomographic techniques take repeated two dimensional pictures, similar to repeatedly slicing through an object, and then assembles them with a computer to produce a three dimensional (3-D) image.
The latest type of CT scan used in dentistry is called CBCT, or Cone Beam Computed Tomography. The Cone Beam refers to a spiral beam of x-rays, which is used to create a series of two dimensional images from which a computer creates a 3-D image. Such an image is of great value in assessing problems and planning treatment.
Here are just a few examples of how a CBCT scan can be used. Orthodontists can see skeletal structures and developing teeth that are still inside the jawbone while planning strategies for directing the teeth in order to arrive at a better bite. Oral surgeons can find impacted or missing teeth, see their locations, and view their proximity to nerves and sinuses, assisting them in planning surgeries. These scans are particularly useful for root canal specialists because they show root canals that are less than a millimeter wide and even reveal accessory canals that may not be visible on conventional x-rays. In cases of sleep disorders such as sleep apnea, a CBCT during sleep can be used to view a person’s airway and how it may be blocked by the tongue and other soft tissues in a person’s throat during sleep.
Compared to background radiation, the amount of radiation delivered in dental x-rays is minimal. A CBCT delivers a dose of radiation that is less than a typical full mouth x-ray series but more than a typical two dimensional panoramic radiograph. Generally CBCT scanners deliver lower doses than medical CT scanners.
With one low-dose CBCT scan, we can get an accurate idea of the internal structure of your bones and teeth and how they are situated in relation to each other. Prior to the availability of such images, many of these relationships had to be discovered in the course of a surgery or other treatment. Thus such a scan can aid greatly in the quality of treatment you will receive.
