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.

A root canal treatment is a highly effective way to save a deeply decayed tooth. Sometimes, though, complications make it difficult or even impossible to perform the traditional procedure. In those cases, we may need to use a different option.
Tooth decay becomes an imminent threat to a tooth's survival if it works its way into the pulp, the innermost layer of a tooth. It's only a short advancement from there into the roots by way of the root canals.
In a typical root canal treatment, we access the pulp by drilling a small hole in the biting surface of a back tooth or the back side of a front tooth. We remove all the tissue within the pulp and fill it and the root canals with a special filling to prevent re-infection. After sealing the access hole, we cap the tooth with a crown to further protect it.
Although root canal treatments have a high success rate, re-infection can still occur. Often, a second root canal will save the tooth from the new infection.
In some cases, though, using the traditional procedure might do more harm than good. It's possible we may find extra canals previously undetected branching out from the primary canal at the root end. Canals can calcify and narrow, making them extremely difficult to fill. Subsequent dental work may also prove troublesome: we would have to take the restoration apart, which could further weaken the tooth.
The alternative is a procedure known as an apicoectomy. Instead of accessing the pulp through the crown, we access the root end through the gum tissue. We then focus on removing infected tissue at the tooth's root end, along with a tiny amount of the root tip. We then place a small filling at the end of the root canal (essentially plugging it up) to prevent further infection. We may also perform grafting to encourage bone growth in any voids left by the procedure.
Endodontists, specialists in root canals, have the advanced training and specialized equipment to perform an apicoectomy. With their expertise, they may be able to save your tooth with this specialized procedure when a root canal treatment won't work.
