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.

Smiling can be a chore for those with missing teeth. Luckily, your dentists at Milford Dental Group in Milford, MA have many options available for replacing those teeth and restoring smiles to their former brilliance. Dr. Peyman Beigi and Dr. Nina Raeisian often suggest crowns and bridges to their patients who either have a tooth in jeopardy of being lost or need to fill in gaps from missing teeth. Learn about these restorations here.
What is a crown?
Like the royal headwear of the same name, dental crowns sit on top of a tooth. But while jewel-encrusted crowns are for decoration, dental crowns don't just improve the tooth's appearance. They protect teeth that have sustained damage from decay or accidents, allowing the wearer to retain the all-important root structure of their natural tooth while still being able to retain its function above the gumline. Crowns from your Milford, MA dentist are typically made from porcelain or porcelain fused to metal, depending on the location of the tooth and how it will be used; for chewing, biting, and so on. Crowns are fabricated in a laboratory using both physical measurements taken by Dr. Beigi and Dr. Raeisian, then attached using a bonding cement. With proper care, you can expect most crowns to last a decade or more before needing replacement or repair.
What is a dental bridge?
Think of a bridge that you drive your car across - it has a beginning and an end point on land, with a section that spans over a body of water or another stretch of road. A dental bridge has the same gap-closing properties. By placing two crowns on the teeth on either side of a gap, a pontic, or artificial tooth, can be sandwiched between them, creating a classic dental bridge. Bridges make eating and speaking easier, and can help prevent tooth decay and bone loss that is often associated with missing teeth.
If you think you might need a crown or a bridge, we at Milford Dental Group in Milford, MA look forward to discussing your options with you! Give us a call today at (508) 966-7023 to set up a consultation.
X-rays revolutionized dental care in the 20th Century. The same could happen in the 21st Century as cone beam computed tomography (CBCT) becomes a fixture beside the traditional x-ray machine.
CBCT made its debut in dental offices about a decade and a half ago. It utilizes the same invisible energy as traditional x-rays to create images of the face and jaw. But unlike traditional x-rays, which can only depict structures in the two dimensions of width and height, CBCT can create three-dimensional images in amazing detail.
The CBCT's x-ray projector rotates around a patient's head. As it emits a cone-shaped beam of x-rays, the device simultaneously collects anywhere from 150 to 599 distinct image views. It transmits these views to a computer that assembles them into three-dimensional images that can be viewed on a computer display.
From the data file of images, dentists can re-format a variety of views and angles of teeth, jaws and other facial bones at various levels of magnification. Because of this wide range of views, all in striking detail, CBCTs are highly useful among other things for diagnosis of malocclusions (bad bites), the size and location of infections, obstructions at possible implant sites, or jaw problems prior to surgery.
Because they expose a patient to higher doses of radiation than a standard x-ray machine, they're normally limited to more complex oral situations. That means you'll still undergo standard x-rays for most of your dental treatment needs. CBCT radiation levels are lower, however, than medical CT scans, which use a fan-shaped beam that can expose a patient to ten times the radiation of a CBCT. For dental care, a CBCT machine also produces greater image detail than an MRI.
Depending on your needs, CBCT may one day be a part of your dental care.Â With their range and accuracy, it could play a major role in helping you attain good health.
