NewFrontTeethforaTeenagedDavidDuchovny

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.

YourOtherTeethMayNeedStraighteningBeforeReplacingaMissingTooth

You’re ready to have that missing tooth replaced with a dental implant or other life-like restoration. But we may first have to address another problem — moving the teeth around the missing tooth space back to where they should be.

That empty space is the primary reason those teeth are no longer in the right position. Through their attachment to the periodontal ligament that lies between them and the bone, teeth are able to move slightly over time in response to mouth changes. This same mechanism, however, may also cause teeth to “drift” toward each other across the empty space left by a missing tooth; too much drift and there won’t be enough room for the replacement tooth.

A fairly straightforward orthodontic treatment can restore drifted teeth to their original position to make room for the replacement. There is one situation, however, that can complicate this treatment — if you also have periodontal (gum) disease, a plaque-induced bacterial infection. During normal tooth movement bone dissolves (resorbs) in front of the tooth in the direction of movement, while new bone forms behind it to help stabilize the tooth in its new position. Gum disease, however, can weaken the bone around these teeth, inhibiting the natural rebuilding process of bone and connective tissue that could jeopardize the success of the orthodontic treatment.

It’s important, then, to first treat and bring the gum disease under control to restore health to both the gums and bone. It’s also just as important during orthodontic treatment to prevent another infection flare-up through renewed brushing and flossing and regular office cleanings and checkups. Choosing clear aligners over traditional braces to move the teeth could also help — unlike fixed braces that often make oral hygiene difficult, clear aligners can be removed to allow easier cleaning of teeth and gums.

Depending on your situation, the process for preparing your mouth for a tooth replacement can involve several procedures and healing time. But the end result — a brand new tooth that looks amazing — will be something to smile about.
