Kristin Cavallari's flawless smile has been featured on TV, film and magazine covers. But the 25-year-old actress and reality-show personality didn't always have a perfect set of teeth. In fact, she told Dear Doctor magazine — where readers recently voted to crown her with the “Smile of the Year” award — that her dental treatments began the same way many do: with orthodontics in sixth grade.
“I had the ‘spaghetti catcher,’ which is what everyone used to call it,” she reminisced. But by that, she didn't mean a strainer — she's talking about what dentists call a “palatal expander.”
In case you're not familiar with this orthodontic device, a palatal expander takes advantage of the natural growth patterns of a child's upper jaw to create additional space for the top set of teeth. How does it work? Basically, it's similar to braces: By applying gentle pressure, the appliance creates changes in the jaw. Unlike braces, however, it's invisible — it fits between the upper teeth, close to the roof of the mouth.
During the three to six months a child wears the palatal expander, it pushes the left and right halves of the upper jawbone apart, and then maintains and stabilizes the new, wider spacing. Since the palatal bones don't fuse until after puberty, tightening it a little bit each day for the first few weeks provides a quick and painless method of making the upper jaw a bit roomier. And that can be a very good thing. Why?
There are lots of reasons. For one, it can relieve the condition called “crowding,” when there is not enough space in the upper jaw to accommodate the proper alignment of the permanent teeth. In the past, teeth often had to be extracted in that situation. It may even allow “impacted” teeth — ones which are blocked from erupting by other teeth — to come in normally.
It can help treat a “crossbite,” when the back top teeth come down to bite inside (instead of outside) the lower back teeth. It also generally shortens the total time a child needs for orthodontic treatment. That's good news for any teenager — even if their own day-to-day “reality show” isn't featured on TV!

In our constant battle against infectious disease, the “enemy” is often too close for comfort: hospitals and other medical facilities must be ever vigilant against opportunistic infections their patients may contract while in their care.
Dental offices are no exception. Because even the simplest procedure — a dental cleaning, for example — may result in exposure, providers and patients alike face a possible health risk. We must be especially concerned with blood-borne viral infections — spread by person to person contact through blood — the most serious being hepatitis B and C, and HIV/AIDS.
Hepatitis is a viral inflammatory disease that disrupts the critical functions of the liver, particularly as it cleanses and regulates the blood, and cause serious bodily impairment or death. The virus can be transmitted when the blood from an infected person makes its way into the bloodstream of another person, mainly through cuts or a needle injection. Human immunodeficiency virus (HIV) can lead to the chronic condition AIDS that destroys the body’s immune system; it spreads mainly through sexual contact, as well as through person to person blood contact.
The best defense against the spread of these diseases in dental offices or other healthcare settings is to eliminate as much as possible any opportunity for blood-to-blood contact. To accomplish this, all healthcare providers, including dentists, are mandated by federal, state and local authorities to incorporate and follow routine safety precautions. The U.S. Center for Disease Control and Prevention (CDC) issues regularly updated comprehensive guidelines for protocols and procedures to disinfect and sterilize equipment and facilities.
We dentists and our clinical staffs are also mandated by state licensing boards to refresh our knowledge of infection control procedures through continuing education. Such procedures cover every aspect of infection control, from barrier protection — by way of gloves, masks or gowns — to instrument disinfection.
Protecting patients as well as providers from the spread of infection is one of our profession’s highest standards. As a result, incidents of infection among the 170,000 practicing dentists in the United States are rare. You can be assured, then, that we’re taking every precaution to keep you and your family safe from disease when you visit our office.
