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.

UseSweetenerSubstitutesWiselytoReduceSugarinYourDiet

Although a variety of foods provide energy-producing carbohydrates, sugar is among the most popular. It’s believed we universally crave sugar because of the quick energy boost after eating it, or that it also causes a release in our brains of serotonin endorphins, chemicals which relax us and make us feel good.

But there is a downside to refined sugars like table sugar or high-fructose corn syrup: too much in our diets contributes to conditions like cardiovascular disease, diabetes, and dental disease. On the latter, sugar is a primary food source for oral bacteria; the more sugar available in the mouth the higher the levels of bacteria that lead to tooth decay and gum disease.

Moderating your intake of refined sugars and other carbohydrates can be hard to do, given that many processed foods contain various forms of refined sugar. A diet rich in fresh fruits and vegetables helps control sugar intake as well as contribute to overall health. Many people also turn to a variety of sugar substitutes: one study found roughly 85% of Americans use some form of it in place of sugar. They’re also being added to many processed foods: unless you’re checking ingredients labels, you may be consuming them unknowingly.

Sugar substitutes are generally either artificial, manufactured products like saccharin or aspartame or extractions from natural substances like stevia or sorbitol. The good news concerning your teeth and gums is that all the major sugar substitutes don’t encourage bacterial growth. Still, while they’re generally safe for consumption, each has varying properties and may have side-effects for certain people. For example, people with phenylketonuria, a rare genetic condition, can’t process aspartame properly and should avoid it.

One alcohol-based sweetener in particular is of interest in oral care. A number of studies indicate xylitol may actually inhibit bacterial growth and thus reduce the risk of tooth decay. You can find xylitol in a variety of gum and mint products.

When considering what sugar substitutes to use, be sure you’re up to date on their potential health effects for certain individuals, as well as check the ingredients labels of processed foods for added sweeteners. As your dentist, we’ll also be glad to advise you on strategies to reduce sugar in your diet and promote better dental health.
