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.

Today, dental implants are an increasingly popular option for replacing lost teeth — an issue faced by many older Americans. It’s not hard to see why these high-tech prosthetic teeth are preferred: They look, “feel” and function just like natural teeth… and with proper care they can last the rest of your life. Unfortunately, many people who could benefit from implants also face an additional health problem: diabetes, a metabolic disease that can affect many different parts of the body, sometimes severely.Â Uncontrolled diabetes can lead to nerve and tissue damage, and may adversely impact your oral health. So if you have diabetes, does it mean you won’t be able to get dental implants?Â
The short answer is no — but there are some considerations that diabetics (and their health care providers) need to keep in mind. For example, it has been demonstrated that wounds in diabetics tend to heal more slowly, and are more prone to infection than those in non-diabetics. Also, people with diabetes sometimes experience a chronic inflammatory response, which can eventually lead to tissue damage or other problems.
Because the placement of dental implants requires minor surgery, dentists and researchers have questioned whether people with diabetes are good candidates for implants. Now there’s encouraging news: Several recent studies have come to the conclusion that many diabetics can indeed undergo an implant procedure without undue risk.
One key consideration is how well an individual can control his or her blood glucose levels. Researchers have found that diabetics with good blood glucose control, those with poor glucose control, and non-diabetics all have similar implant success rates (above 95%). However, in diabetics with poor glucose control, more time may be needed for the jawbone to heal in the area where the implant procedure was done. That doesn’t by any means rule out the placement of a dental implant — but it does mean that special considerations apply to individuals in this situation.
So if you are considering an implant procedure but have trouble controlling your blood glucose levels, ask us how we can help. Just remember that in most cases, having diabetes doesn’t mean you won’t be able to enjoy the benefits of dental implants. If you have additional questions, contact us or schedule an appointment.
Normally, teeth erupt and grow in a symmetrical alignment: on the top palate, for example, the two central incisors take center stage; on either side are the lateral incisors, and then beside these the canines (cuspids).
But what happens when teeth don’t grow in? The result can be a smile that just doesn’t quite look right; more importantly, normal function is impaired because the person can’t grasp and chew food correctly.
These missing teeth are the result of a congenital (“from birth”) defect. It’s estimated that almost a quarter of all people are missing one or more wisdom teeth, and more than 5% are missing one or more second premolars or upper lateral incisors.
In a normal arch (the upper or lower set of teeth), each tooth type performs a particular role during eating. A missing tooth causes the remaining teeth to compensate, but beyond their capacity. The remaining teeth also tend to move to fill in any gaps left by the missing teeth, as when the eye teeth move toward the central incisors in the absence of the lateral incisors. This puts them out of position, so they can’t cover (“occlude”) their counterparts on the other arch and grasp food properly.
To improve the smile and restore proper chewing function it’s necessary to first move these “out of position” teeth to their correct position through orthodontics. We would then fill the gaps that result with life-like restorations (preferably dental implants with crowns) that resemble the type of tooth that should be there.
The restoration needs to be timed carefully, especially for young patients whose jaw structure has not fully developed. If implants are installed before the jaw’s full maturity (usually late teens or early twenties), the implant crowns may not appear to be the right length as the jawbone continues to grow. Since bone growth depends on the normal pressures exerted by the teeth, there may also be insufficient bone mass in the gap area to support a dental implant. Growing bone with bone-grafting material may be necessary before installing implants.
The total process could take many months or even years, depending on age and other conditions. In the end, though, the results can be astounding — better function and a vibrant, new smile.

Dental implants have quickly become the restoration of choice for two basic reasons: they effectively restore the lost function of missing teeth and simultaneously rejuvenate the smile with their life-like appearance.
Achieving a life-like appearance, however, isn’t always a simple matter. A restoration in what we dentists call the “Smile Zone” (the upper front area that displays both teeth and the gum line when you smile) requires careful planning and technique to ensure they appear as life-like as possible.
Our first concern is whether there’s enough bone to fully anchor an implant. Bone is a living, dynamic tissue that goes through cycles of dissolving (resorption) and growth. The normal forces of biting and chewing transmit through healthy teeth and stimulate growth in the bone. When the teeth are missing and no longer transmit this pressure, the bone will eventually resorb only and not grow.
Adjacent teeth could also be affected with bone loss if the extraction was difficult and a bone graft was not placed into the extraction socket to preserve bone. This not only puts adjacent teeth at risk of gum and bone loss but can also have implications for the final smile appearance. This bone also supports the triangular tissue between teeth known as papillae which give teeth their arched appearance. If the bone isn’t adequate, there’s less hope that the papillae will regenerate.
With these concerns it’s very important to consider how the implant and crown emerges from the gums in the Smile Zone. Recent developments in implant design are helping in this regard. The design change of the top of the implant re-orients the gum tissues in relation to the implant from vertical to horizontal, which dentists call “platform switching.” This provides greater stabilization where bone mass is limited, and helps create a more aesthetically pleasing result. There are also other techniques, such as surgical tissue grafting of the papillae that can further enhance the final appearance.
Although creating a natural, life-like appearance in the Smile Zone is difficult, it’s not impossible. It’s important first to undergo a complete dental examination and profile, where we can advise you on your best options to achieve a beautiful smile.

If you follow the hit TV reality show Amazing Race, you know that professional-hockey-playing brothers Bates and Anthony Battaglia won the $1 million prize in the latest globe-spanning competition. You may also have witnessed Anthony removing his false front teeth from time to time — like when he had to dive for pearls in Bora Bora. Since he plans to resume his sports career, Anthony wears a partial denture to fill the gap in his classic “hockey mouth.” He has said that when he finally hangs up his skates, he will use some of his Amazing Race prize money to get new, permanent teeth. When it's time to get that new smile, Anthony, like many people, will have to choose between two good options for permanent tooth replacement.
The preferred option for most people is dental implants. In this system, tiny titanium posts substitute for the root part of your missing tooth (or teeth). These are placed beneath your gum line in a minor surgical procedure we perform right here at the dental office. The amazing thing about dental implants is that they actually fuse to your jawbone, allowing your replacement teeth to last a lifetime.
The titanium implant itself is not visible in the mouth; the part of an implant tooth that you see is the lifelike crown. Virtually indistinguishable from your natural teeth, the crown is attached to the implant above the gum line. Dental implants can be used to replace a single tooth, multiple teeth, or even all your teeth. You don't necessarily need one implant for every tooth because implants can support bridgework or even a complete set of prosthetic teeth.
The second-best option is a natural-tooth fixed bridge. In this system, we use healthy natural teeth on either side of the empty space left by a missing tooth (or teeth) as supports for one or more of the prosthetic teeth that will fill the gap. The downside is that in order to turn these healthy teeth into supports (which are referred to in dentistry as “abutments”), we need to remove some enamel and then cap them. This procedure can leave those teeth more prone to decay than they were before. But with regular dental exams and good oral hygiene on your part, bridgework can last many years.
Which system is right for you? That's a question we would be happy to help you determine... even if you haven't won a large jackpot or gone pearl diving in Bora Bora.
