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.

First introduced in the 1980s, dental implants are a popular and reliable tooth replacement option. Numerous studies show that after ten years 95% are still in place. Much of this success owes to the implant’s titanium post imbedded directly into the jaw, which then attracts bone growth. This additional growth securely anchors the implant in place for an unrivaled durability among other replacement options.
Still, a small percentage of implants fail — some in the first few months and others after a few years. Here are 3 reasons why, and how you can overcome them.
Poor bone quantity and quality. Implants need a certain amount of existing bone to succeed. Sometimes, though, there isn’t enough because prolonged absence of a tooth causes bone loss around the empty socket. Conditions like diabetes, osteoporosis or tobacco use can also compromise bone health. It’s often possible to increase bone volume with grafting, especially right after tooth extraction.
Teeth grinding habits. This occurs when you unconsciously grind or clench your teeth, usually during sleep. The habit can create forces far in excess of what’s normal when we bite or chew and can damage or even break the crown attached to an implant. Besides reducing stress (a major factor for teeth grinding), you can also alleviate the abnormal force generated by wearing a night guard.
Periodontal (gum) disease. Although your implants are impervious to disease or infection, supporting gums and bone aren’t. Plaque, a film of food and bacteria that builds up on tooth surfaces, can cause gum disease that weakens the supporting tissues (gums and bone) of the implant. This can give rise to a specific condition with implants known as peri-implantitis where the infected gum tissues and bone around it deteriorate, leading to the implant’s catastrophic loss. To avoid this, practice consistent daily hygiene, including around the implant. And see us regularly for checkups and cleanings, or as soon as possible if you see signs of gum problems.
