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.

Moving your teeth to a more functional and attractive alignment is a big undertaking. You can invest months — even years — and a lot of expense to correct a bad bite. But all that effort could be for nothing if your teeth return to their original positions.
The very aspect of dental physiology that makes orthodontics possible can work against you in reverse. Your teeth are not actually rigidly fixed in the bone: they're held in place by an elastic gum tissue known as the periodontal ligament. The ligament lies between the tooth and the bone and attaches to both with tiny fibers.
While this mechanism holds the teeth firmly in place, it also allows the teeth to move in response to changes in the mouth. As we age, for example, and the teeth wear, the ligament allows movement of the teeth to accommodate for the loss of tooth surface that might have been created by the wear.
When we employ braces we're changing the mouth environment by applying pressure to the teeth in a certain direction. The teeth move in response to this pressure. But when the pressure is no longer there after removing the braces or other orthodontic devices, the ligament mechanism may then respond with a kind of “muscle memory” to pull the teeth back to where they were before.
To prevent this, we need to help the teeth maintain their new position, at least until they've become firmly set. We do this with an oral appliance known as a retainer. Just as its name implies it helps the teeth “retain” their new position.
We require most patients to initially wear their retainer around the clock. After a while we can scale back to just a few hours a day, usually at nighttime. Younger patients may only need to wear a retainer for eighteen months or so. Adults, though, may need to wear one for much longer or in some cases permanently to maintain their new bite.
Although having to wear a retainer can be tedious at times, it's a crucial part of your orthodontic treatment. By wearing one you'll have a better chance of permanently keeping your new smile.

Magician Michel Grandinetti can levitate a 500-pound motorcycle, melt into a 7-foot-tall wall of solid steel, and make borrowed rings vanish and reappear baked inside bread. Yet the master illusionist admits to being in awe of the magic that dentists perform when it comes to transforming smiles. In fact, he told an interviewer that it’s “way more important magic than walking through a steel wall because you’re affecting people’s health… people’s confidence, and you’re really allowing people to… feel good about themselves.”
Michael speaks from experience. As a teenager, his own smile was enhanced through orthodontic treatment. Considering the career path he chose for himself — performing for multitudes both live and on TV — he calls wearing an orthodontic device (braces) to align his crooked teeth “life-changing.” He relies on his welcoming, slightly mischievous smile to welcome audiences and make the initial human connection.
A beautiful smile is definitely an asset regardless of whether you’re performing for thousands, passing another individual on a sidewalk or even, research suggests, interviewing for a job. Like Michael, however, some of us need a little help creating ours. If something about your teeth or gums is making you self-conscious and preventing you from smiling as broadly as you could be, we have plenty of solutions up our sleeve. Some of the most popular include:
- Tooth Whitening. Professional whitening in the dental office achieves faster results than doing it yourself at home, but either approach can noticeably brighten your smile.
- Bonding. A tooth-colored composite resin can be bonded to a tooth to replace missing tooth structure, such a chip.
- Veneers. This is a hard, thin shell of tooth-colored material bonded to the front surface of a tooth to change its color, shape, size and/or length; mask dental imperfections like stains, cracks, or chips, and compensating for excessive gum tissue.
- Crowns. Sometimes too much of a tooth is lost due to decay or trauma to support a veneer. Instead, capping it with a natural-looking porcelain crown can achieve the same types of improvements. A crown covers the entire tooth replacing more of its natural structure than a veneer does.
