In real life he was a hard-charging basketball player through high school and college. In TV and the movies, he has gone head-to-head with serial killers, assorted bad guys… even mysterious paranormal forces. So would you believe that David Duchovny, who played Agent Fox Mulder in The X-Files and starred in countless other large and small-screen productions, lost his front teeth… in an elevator accident?
“I was running for the elevator at my high school when the door shut on my arm,” he explained. “The next thing I knew, I was waking up in the hospital. I had fainted, fallen on my face, and knocked out my two front teeth.” Looking at Duchovny now, you’d never know his front teeth weren’t natural. But that’s not “movie magic” — it’s the art and science of modern dentistry.
How do dentists go about replacing lost teeth with natural-looking prosthetics? Today, there are two widely used tooth replacement procedures: dental implants and bridgework. When a natural tooth can’t be saved — due to advanced decay, periodontal disease, or an accident like Duchovny’s — these methods offer good looking, fully functional replacements. So what’s the difference between the two? Essentially, it’s a matter of how the replacement teeth are supported.
With state-of-the-art dental implants, support for the replacement tooth (or teeth) comes from small titanium inserts, which are implanted directly into the bone of the jaw. In time these become fused with the bone itself, providing a solid anchorage. What’s more, they actually help prevent the bone loss that naturally occurs after tooth loss. The crowns — lifelike replacements for the visible part of the tooth — are securely attached to the implants via special connectors called abutments.
In traditional bridgework, the existing natural teeth on either side of a gap are used to support the replacement crowns that “bridge” the gap. Here’s how it works: A one-piece unit is custom-fabricated, consisting of prosthetic crowns to replace missing teeth, plus caps to cover the adjacent (abutment) teeth on each side. Those abutment teeth must be shaped so the caps can fit over them; this is done by carefully removing some of the outer tooth material. Then the whole bridge unit is securely cemented in place.
While both systems have been used successfully for decades, bridgework is now being gradually supplanted by implants. That’s because dental implants don’t have any negative impact on nearby healthy teeth, while bridgework requires that abutment teeth be shaped for crowns, and puts additional stresses on them. Dental implants also generally last far longer than bridges — the rest of your life, if given proper care. However, they are initially more expensive (though they may prove more economical in the long run), and not everyone is a candidate for the minor surgery they require.

One of the most important revolutions in healthcare in recent decades is the increasing use of lasers. Now, laser technology is making a showing in dental care for the treatment of periodontal (gum) disease.
Lasers (an acronym for "Light Amplification by Stimulated Emission of Radiation") narrowly focus and amplify light within a small area. First developed in the early 1960s, laser technology rapidly advanced in the ensuing decades with more compact and precise devices that were eventually safe and effective for many types of medical procedures. Its remarkable features are now available for the primary focus of gum disease treatment—removing bacterial plaque.
Plaque is a thin, built-up film of bacteria and food particles on tooth and gum surfaces that serves as a haven for the bacteria that cause gum disease. The continuing presence of plaque and calculus (tartar) enables the infection to thrive and advance within the gum tissues, ultimately damaging them along with supporting bone. As the tissues weaken and bone volume diminishes, the teeth are at greater risk for loss.
It's necessary, therefore, first and foremost to remove all detectable plaque and calculus to stop the infection. This is traditionally done with special hand tools called scalers used to manually remove plaque, or with ultrasonic equipment that vibrates plaque loose to be flushed away with water. These procedures can take numerous sessions and may result in some minor post-procedural discomfort and bleeding during the cleaning.
But lasers specifically designed for plaque removal can minimize tissue damage and resulting discomfort. Because the particular laser light used reacts only with plaque and diseased tissue, it can remove them without disturbing nearby healthy tissue usually more efficiently than traditional scaling. Dentists who've used the technology frequently report less bleeding and higher patient satisfaction.
But before lasers for gum disease treatment are widely adopted, the procedure must undergo further scrutiny. Reports from dentists notwithstanding, not enough research studies have been performed to date that meet the necessary scientific criteria. But if the evidence so far from the field holds up, it's quite possible lasers will one day become a regular part of dental practice for treating gum disease.

The primary goal of dental care is to preserve teeth. But there are circumstances in which removing a tooth, even a relatively healthy one, could prove best in the long run.
A malocclusion (poor bite) related to crowding might fit such a circumstance. Crowding occurs when the size of the jaw is too small for the teeth coming in. With not enough space, some teeth could erupt out of their proper positions. Removing certain teeth frees up space to eventually allow braces or other orthodontic devices to re-align the teeth.
The teeth most frequently removed are the first bicuspids, located between the cuspid (the "eyeteeth" directly under the eyes) and the back teeth, and the second premolar. Removing these won't normally affect appearance or functionality once orthodontic or cosmetic treatments are complete.
Because of the mechanics of jaw development it might be necessary to perform these extractions several years before orthodontic treatment. This could create another potential problem: the time lag could adversely affect bone health.
This is because bone, as living tissue, has a life cycle with cells forming, functioning and then dissolving, and new cells taking their place. When teeth are chewing or in contact with each other they generate force that travels through the tooth roots to the bone and stimulates cell growth at a healthy replacement rate.
But when a tooth is missing, so is this stimulation. This slows the replacement rate and eventually leads to decreased bone volume. Too much bone loss could create obstacles for orthodontic treatment or a future dental implant.
To avoid this, the dentist will often place a bone graft with processed bone mineral within the empty tooth socket right after extraction. The graft serves as a scaffold for bone cells to grow upon. The graft (plus any other added growth boosters) can help maintain a healthy level of bone volume to facilitate future orthodontic or restorative treatments.
Since targeted extraction for orthodontics is time-sensitive, you should have your child's bite evaluated by an orthodontist by age 7 to see if any action is necessary. The earlier a malocclusion is detected, the more likely a more attractive and healthy smile will be the ultimate outcome.

Spring means different things to different people—but to baseball fans, it means just one thing: the start of another thrilling season. All 30 Major League Baseball teams begin play this month, delighting fans from Toronto to Texas and everywhere in between.
The boys of spring carry on an age-old tradition—yet baseball is also changing with the times. Cigarette smoking has been banned at most ballparks for years; smokeless tobacco is next. About half of the MLB venues now prohibit tobacco of any kind, including “snuff” and “dip.” What’s more, a recent contract agreement bars new Major League players from using smokeless tobacco anywhere.
Why all the fuss? Because tobacco isn’t safe to use in any form. People who use smokeless tobacco get just as much highly addictive nicotine as cigarette smokers. Plus, they get a mouthful of chemicals that are known to cause cancer. This puts them at higher risk for oral cancer, cancer of the esophagus, pancreatic cancer and other diseases.
A number of renowned ballplayers like Babe Ruth, Curt Flood and Bill Tuttle died of oral cancer. The death of Hall of Famer Tony Gwinn in 2014 focused attention on tobacco use in baseball, and helped lead to the ban. Gwynn was convinced that his addiction to smokeless tobacco led to his getting oral cancer.
Yet tobacco isn’t the only cause of oral cancer. In fact, the disease is becoming more common in young people who do not smoke. That’s one more reason why it’s so important for people of all ages to keep to a regular schedule of routine dental exams. These visits offer a great opportunity to detect oral cancer in its earliest, most treatable stages.
So as you watch your favorite team, take a tip from the professional athletes’ playbook. If you don’t use tobacco, don’t start. If you do, now is a good time to quit. For help and support, call an expert at 1-800-QUIT-NOW or visit smokefree.gov.
