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.

Controlling discomfort during dental work is one of our top priorities. Advances in anesthesia over the last century have made that objective easier to attain, especially for routine procedures.
The term anesthesia means “without feeling or pain.” It refers to the use of substances to prevent a patient’s nervous system from sensing pain. There are two basic types: general, through intravenous injection (IV) or gas inhalation that places a patient in an unconscious state; and local, which only affects the part of the body involved in the procedure while the patient remains conscious.
The latter type has become very important in dentistry, especially for mild to moderate procedures. Because teeth and gum tissues are rich in nerves, patients can have a heightened level of sensitivity that can increase anxiety and discomfort during dental work. Local anesthesia reduces that discomfort and relaxes both patient and dental provider.
We typically administer local anesthesia in two ways: by applying the anesthetic to the outside tissue surface (with a cotton swab, patch or spray) or by injection. The first type, topical anesthesia, is most often used to eliminate the pricking discomfort of the needle used to inject the main anesthetic. Using both applications eliminates any painful sensation at all — the only thing you might feel is a slight pressure during the procedure.
As mentioned before, local anesthesia benefits us as well as you. Knowing you’re at ease and comfortable allows us to better focus on the procedure — we’re not rushed to finish to spare you further discomfort. A relaxed, unhurried atmosphere is essential to a successful outcome for any dental procedure.
We’ve also found solutions for another issue with local anesthesia that concerns patients: the length of time the numbing effect lingers after a procedure. In response, the dental profession has developed different types of anesthesia that reduce this after effect considerably. We’re also more selective about what procedures actually require anesthesia — some, like routine teeth cleaning or work on the outer enamel (which doesn’t contain nerves), can usually be performed without it.
All in all, local anesthesia reduces your level of discomfort and increases our ability to be thorough in performing your dental work. You’ll not only find the experience more pleasant, but it will also enhance the quality of your care.
