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.

Over a lifetime, teeth can endure temperatures ranging from freezing to near boiling, biting forces of as much as 150 pounds per square inch and a hostile environment teeming with bacteria. Yet they can still remain healthy for decades.
But while they’re rugged, they’re not indestructible — they can incur serious damage from tooth decay or periodontal (gum) disease, two of the most prevalent oral infections. If that happens, you could be faced with the choice of removing the tooth or trying to save it.
Because today’s restorations like dental implants are quite durable and amazingly life-like, it might seem the decision is a no-brainer — just rid your mouth of the troubled tooth and replace it. But from a long-term health perspective, it’s usually better for your gums, other teeth and mouth structures to try to save it.
How we do that depends on the disease and degree of damage. Tooth decay, for example, starts when high levels of acid soften the minerals in the outer enamel. This creates a hole, or cavity, that we typically treat first by filling with metal amalgam or, increasingly, composite resins color-matched to the tooth.
If decay has invaded the pulp (the innermost layer of the tooth), you’ll need a root canal treatment. This procedure removes infected material from the pulp and replaces the empty chamber and the root canals with a special filling to guard against another infection. We then cap the tooth with a life-like crown for added protection.
Gum disease, on the other hand, is caused by dental plaque (a thin film of bacteria and food particles on tooth surfaces), and requires a different approach. Here, the strategy is to remove all of the plaque and calculus (hardened plaque deposits) we can find with special hand instruments or ultrasonic equipment, and often over several sessions. If the infection extends deeper or has created deep pockets of disease between the teeth and gums, surgery or more advanced techniques may be necessary.
Though effective, some of these treatments can be costly and time-consuming; the tooth itself may be beyond repair. Your best move is to first undergo a complete dental examination. From there, we can give you your best options for dealing with a problem tooth.
