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.
When they’re introducing a new movie, actors often take a moment to pay tribute to the people who helped make it happen — like, you know, their dentists. At least that’s what Charlize Theron did at the premiere of her new spy thriller, Atomic Blonde.
"I just want to take a quick moment to thank my dentists," she told a Los Angeles audience as they waited for the film to roll. "I don’t even know if they’re here, but I just want to say thank you."
Why did the starring actress/producer give a shout-out to her dental team? It seems she trained and fought so hard in the action sequences that she actually cracked two teeth!
“I had severe tooth pain, which I never had in my entire life,” Theron told an interviewer from Variety. At first, she thought it was a cavity — but later, she found out it was more serious: One tooth needed a root canal, and the other had to be extracted and replaced with a dental implant — but first, a bone grafting procedure was needed. “I had to put a donor bone in [the jaw] to heal,” she noted, “and then I had another surgery to put a metal screw in there.”
Although it might sound like the kind of treatment only an action hero would need, bone grafting is now a routine part of many dental implant procedures. The reason is that without a sufficient volume of good-quality bone, implant placement is difficult or impossible. That’s because the screw-like implant must be firmly joined with the jawbone, so it can support the replacement tooth.
Fortunately, dentists have a way to help your body build new bone: A relatively small amount of bone material can be placed in the missing tooth’s socket in a procedure called bone grafting. This may come from your own body or, more likely, it may be processed bone material from a laboratory. The donor material can be from a human, animal or synthetic source, but because of stringent processing techniques, the material is safe for human use. Once it is put in place your body takes over, using the grafted material as a scaffold on which to build new bone cells. If jawbone volume is insufficient for implants, it can often be restored to a viable point in a few months.
Better yet, when grafting material is placed in the tooth socket immediately after extraction, it can keep most of the bone loss from occurring in the first place, enabling an implant to be placed as soon as possible — even before the end of a movie’s shooting schedule.
Will Atomic Blonde prove to be an action-movie classic? Only time will tell. But one thing’s for sure: When Charlize Theron walks down the red carpet, she won’t have to worry about a gap in her smile.

When he isn’t among the ten players vying for position on the basketball court, Cole Aldrich of the New York Knicks sometimes lets his dangle behind one ear. Mason Plumlee, who plays for the Brooklyn Nets, slips his snugly inside one of his socks during off times. Other players can be seen at timeouts gnawing on them nervously, or tucking them into spandex waistbands. But when the whistle blows, they go into the mouth before the players get on the court.
We’re talking about protective mouthguards, of course. According to a recent story in the New York Times, only a handful of basketball players wore them regularly a few years ago. Today, more and more are wearing them, both in practice and during games. What’s the reason for the change?
Partly, it’s the result of better design and improved construction; today’s mouthguards are more comfortable and better-fitting than ever. Part of it comes from mounting evidence that they work: Research studies have consistently demonstrated the benefits of wearing a mouthguard — not only to protect the teeth, but also to reduce the risk of concussion. And partly, it stems from the growing acceptance that safety is an important aspect of all athletic activity.
If the pros are doing it — shouldn’t you be too? While you may think that only contact sports (such as football) are risky, the fact is that “non-contact” sports like baseball and basketball account for the majority of dental injuries. In fact, the American Dental Association recommends you wear a mouthguard when you participate in activities like handball, soccer, surfing and weight lifting — as well as boxing, skydiving, martial arts and “extreme sports” — whatever that may mean to you.
What’s the best kind of mouthguard? It’s the one that you actually wear, of course! And the most comfortable and best-fitting mouthguard is the one that’s custom-made for you by your dentist. Sure, you can pick up an off-the-shelf mouthguard at a big box store; but it can’t offer you the same level of protection and comfort you’ll get from a mouthguard that is made from a model of your own teeth. Custom-made mouthguards from your dentist are reasonably priced — and by preventing dental trauma, they can save an untold amount of hurt… both to your body and to your pocketbook.
So take a tip from the pros: Get a custom-made mouthguard, and wear it every time you play. But when you’re done playing… how about putting it away in a case?
