Everyone knows Vanna White as the elegant co-host of the popular game show Wheel of Fortune. But here's one thing you may not know: White is listed in the Guinness Book of World Records as television's most frequent clapper, with an average of 720 claps per show — that's over 28,000 per season! And here's something else: the star with the megawatt smile wore braces as a kid, and she's not too shy to talk about it.
“I only had to wear them for a year and it was a good experience for me,” she told an interviewer for Dear Doctor magazine. But when it was time for her son to get them, White noticed something different. “We used to have those silver bands that went all the way around each tooth, and they don't have that anymore. It is fascinating to see how far they have come.”
We're glad she noticed! In fact, orthodontic appliances have advanced a good deal in the past decade or so. Instead of using metal bands, brackets holding the wire part of braces are now typically attached directly to the teeth with a dental adhesive. For an even less obtrusive look, ask about using colorless brackets instead of metal ones — that way, the only part that's clearly visible is the thin wire itself. And in some situations, braces can be placed on the lingual (tongue) side of the teeth, making them all but invisible.
Another type of nearly invisible appliance is the clear orthodontic aligner. The aligner system consists of a series of precision-made transparent “trays” that fit over the teeth. Each tray is worn for a few weeks, and each moves your teeth by a small amount; together, they can help correct mild to moderate orthodontic problems. And the best part — they're really hard to notice! That makes them perfect for both adults concerned about a “professional” look, and image-conscious teens.
So if you're a TV star — or if you'd just like to have a brighter and better smile — it's never too late to get started!

For years preparing teeth for fillings or other restorations has required the use of a drill. Although quite effective in removing decayed structure and preparing the tooth for bonding, it usually requires a local anesthetic. That and the noise it generates can be unsettling for many patients.
In recent years, a different type of technique known as “air abrasion” has increased in popularity among dentists. Known also as “particle abrasion,” the technique uses a stream of fine particles to remove decayed tooth structure and is less invasive than the traditional drill. Although the technology has been around since the mid-20th Century, recent developments in suction pumps that remove much of the dust created have made it more practical. It also works well with new natural-looking bonding materials used for tooth structure replacement.
The fine particles — usually an abrasive substance like aluminum oxide — are rapidly discharged through a hand-held instrument using pressurized air aimed at affected tooth areas. Decayed teeth structure is softer than healthier tissue, which allows air abrasion to precisely remove decay while not damaging the other.
Besides removing decay or abrading the tooth for bonding, air abrasion can also be used to minimize stained areas on surface enamel and to clean blood, saliva or temporary cements from tooth surfaces during dental procedures. It’s also useful for smoothing out small defects in enamel or aiding in sealant applications.
It does, however, have a few limitations. It’s not as efficient as the traditional drill with larger cavities or for re-treating sites with metal (amalgam) fillings. Because of the fine texture of the abrasive particles, affected teeth need to be isolated within the mouth using a rubber dam or a silicone sheet. High-volume suction must be continually applied to capture the fine particles before the patient swallows them or it fills the procedure room with a fine cloud of material.
Still, while air abrasion technology is relatively new, it has clear advantages over the traditional drill in many procedures. As advances in the technology continue, air abrasion promises to offer a more comfortable and less invasive experience in dental treatment.
