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!

Did you know that tooth decay (dental caries) is the second most frequently occurring disease — surpassed only by the common cold? It can start as soon as toddlers sprout their first teeth and by middle age, more than 90% of adults are affected by the problem! Fortunately, you can significantly lower your risk for decay. The key is to nurture health-promoting (protective) factors in your mouth while discouraging those that are disease causing (pathologic).
The top two traditional steps can't be stressed enough:
Good Oral Hygiene. Diligent brushing and flossing, along with routine professional cleanings, help limit a buildup of bacterial plaque (biofilm). This whitish film is attractive to decay-producing bacteria (among the many types of bacteria — including beneficial ones — that normally live in the mouth). These microbes like to snack on sugars and carbohydrates (perhaps part of that bagel you had for breakfast or the midafternoon candy bar), and in the process they produce acid. A healthy oral environment has a neutral pH — a perfect balance between acids and bases. But in a more acidic environment, minerals in the protective enamel of your teeth start to dissolve, exposing the dentin and root surfaces underneath that are even more vulnerable.
Sensible Diet. Keep decay-producing bacteria in check by limiting your intake of sugars and carbohydrates; the bacteria need these nutrients to grow and reproduce. Choose products containing natural sugars, such as those in fruits and vegetables, over those containing added sugars, such as sodas and candy. Be aware that Xylitol, an “alcohol sugar” used in some chewing gums and dental products, can actually help reduce pathogenic bacteria. And don't forget that frequent consumption of acidic foods and beverages, such as sipping coffee during the day, can create an acidic environment in your mouth that can contribute to decay by eroding tooth enamel and weakening its defenses.
Individual Risk Factors
You also may have individual risk factors as well that our office can help you identify and address. For example, the shape of everyone's teeth varies and some of us have more valleys, tiny grooves and pits than others. These likely places for bacteria to congregate can be the most difficult to reach with a toothbrush, but invisible sealants can be applied to prevent bacteria from reaching those areas.
