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.

ChooseaMouthrinseCarefullyifyouwanttoEnhanceyourDentalHealth

Many people use a mouthrinse as part of their daily oral hygiene. If you’d also like to include a mouthrinse in your regimen, the kind you choose will depend on what you want it to do for you.

If your main desire is fresh breath, then a cosmetic rinse that imparts a minty smell to the mouth should fit the bill. That, however, is all they do — cosmetic mouthrinses don’t contribute to oral health beyond your personal satisfaction that your breath is free of bad odors. But, if you want more — added protection against dental disease, for example — then you’ll need to consider a therapeutic mouthrinse.

Therapeutic mouthrinses are usually described as anti-cariogenic (prevents decay) or anti-bacterial, and include both over-the-counter (OTC) and prescription rinses. Their purpose is to either strengthen teeth or reduce the mouth’s bacterial levels. Of the OTC variety, most contain a small amount of sodium fluoride, which can strengthen tooth enamel. They’ve proven highly effective: a number of studies show using a sodium fluoride mouthrinse in conjunction with brushing and flossing reduces the chances of new cavities forming.

A number of OTC rinses also have an anti-bacterial effect, usually provided by active ingredients such as triclosan, zinc or essential oils like menthol. Even a slight reduction in bacteria can help lessen the chances of gingivitis (gum inflammation), an early form of periodontal (gum) disease. Reducing bacteria levels may also help alleviate bad breath.

Some individuals, though, have higher than normal levels of bacteria, or a systemic weakness in fighting certain bacterial strains. If this is your case, you might benefit from a prescribed mouthrinse intended to lower bacterial levels. Most prescription mouthrinses contain chlorhexidine, which has been amply demonstrated as an effective anti-bacterial control of tooth decay and gum disease. Chlorhexidine prevents bacteria from adhering to the teeth and so disrupts plaque buildup, the main cause of dental disease. Its prolonged use will result in the dark staining of teeth in some people, but this can be removed during dental cleanings and teeth polishing. Long-term use is generally not preferred compared to getting the proper attention from regular cleanings and examinations.

If you would like more advice on adding a mouthrinse to your daily hygiene regimen, especially to help reduce your risk of dental disease, please feel free to discuss this with us at your next checkup. Regardless of which type of mouthrinse you choose, they should always be used as a complement to daily brushing and flossing, along with regular dental cleanings and checkups.
