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.

Periodontal (gum) disease is an aggressive bacterial infection caused by built-up plaque on tooth surfaces. Gum disease results in bone loss and causes loss of attachment from the teeth, leading to eventual tooth loss.
The goal of any gum disease treatment is to remove as much plaque and calculus (hardened deposits of plaque) from the gums and teeth as possible. Scaling with special hand instruments or ultrasonic equipment is the basic technique for plaque and calculus removal above and below the gum line. As the infection spreads below the gum line, it can widen the natural gap between teeth and gums to form voids known as periodontal pockets that fill with infection. Accessing and cleaning these pockets, which can occur as deep as the tooth roots, will require more invasive procedures.
Pockets that form at a depth greater than 5 mm below the gum line will most likely require surgical access through the gum tissue. But for pockets not quite that deep there’s an intermediary technique called root planing without surgical intervention. As the name suggests, the roots are physically “planed,” much like shaving a wooden board to remove minute layers of wood.
Using similar instruments as with scaling, root planing removes calculus, bacteria and other infected matter adhering to the root surfaces. It’s best to perform the procedure with local anesthesia to numb the gum tissues, which may be quite sensitive depending on the degree of infection. Working in a pain-free environment also helps us to be as thorough as possible in detecting and removing every bit of plaque and calculus we can find.
In advanced cases, it may be necessary to perform this procedure during multiple visits. As plaque and calculus are removed the inflammation in affected tissues will begin to subside, revealing more deposits of plaque and calculus. It’s also important to begin and maintain a daily habit of effective brushing and flossing to lessen the chances of a recurring infection.
Treating gum disease is an ongoing effort that requires constant monitoring and sustained efforts to remove plaque and calculus, including root planing. Saving your teeth, however, is well worth the effort.
