NewMaterialsAddStrengthtoVeneersBeautifulLife-Likeness

With exciting innovations in cosmetic dentistry over the last few decades, we can now transform nearly any unattractive smile. One of the best and most cost-effective of these is the porcelain veneer. These thin layers of dental porcelain are bonded over the front of chipped, slightly misaligned or stained teeth to create an entirely new look.

Veneers have evolved over time, especially with the materials they contain that give them their beauty and life-likeness. The first veneers were made mainly of feldspathic porcelain, a mineral composition known for its similarity in color and translucence to natural teeth.

But because this early porcelain had a high amount of silica (in essence, glass), and because they were created through overlaying several thin layers that weren’t as strong as a single piece, they were prone to shattering. This made them problematic for teeth subject to heavy biting forces or patients with clenching or grinding habits.

The situation changed dramatically in the 1990s, when dental labs began adding Leucite, a sturdier glass-like mineral that didn’t diminish the porcelain’s translucence. Not only did Leucite make veneers more shatter-resistant, it also enabled dental technicians to fashion most of the veneer in one piece to further strengthen it.

More recent veneers may now incorporate an even stronger material called lithium disilicate. Because lithium disilicate has twice the strength of Leucite, veneers made with it can be as thin as 0.3 millimeters. Not only does this blend together the most desirable qualities expected of a veneer—strength, aesthetic appeal and easy fabrication—it allows for a broader range of situations and uses.

Both of these materials can be pressed or milled to assume the exact shape necessary to fit a particular tooth. The manufacturing process also allows for creating smaller veneers that can then be overlaid with porcelain for the most life-like appearance possible.

Thanks to these stronger materials enhancing the natural beauty of porcelain, we now have a wider creative palate for transforming your smile.

CelebratingPaulReverePatriotandDentalCraftsman

While celebrating all that a new year brings, take a moment to remember the New Year's Day birthday of a true American patriot: the legendary Paul Revere. Ironically, he became a legend some 80 years after his midnight trek to warn colonists of approaching British troops, thanks to Henry Wadsworth Longfellow's 1861 poem “Paul Revere's Ride.” He was much better known to his fellow Bostonians as a prosperous silversmith, engraver—and “artificial teeth” maker.

That's right. Among his many business endeavors, Revere's résumé also included dental prosthetics, specifically custom dentures made of ivory. For the time, his work was state-of-the-art technology that far surpassed older tooth replacement methods.

But when we compare Revere's foray into the dental arts and today's restorations, his high quality 18th Century dentures were the proverbial “horse and buggy,” while modern denture technology seems like “supersonic transport.” Not only are today's dentures made of superior materials that are more “toothlike” in appearance, the means to create them using digital technology gives wearers a more secure and comfortable fit.

The modern denture—an appliance that replaces multiple or all lost teeth—is composed of a polymer base, usually acrylic that is colored to resemble gum tissue. Attached to this base are the prosthetic (“false”) teeth that replace those lost along the jaw. These new teeth are usually made of a durable dental material like porcelain that looks and functions like real teeth.

The basic design of today's denture hasn't changed much in the last century. What has changed is our ability to create dentures that follow an individual jaw contours much more precisely. Using the latest digital technology, we're able to obtain highly accurate impressions of the mouth to guide the manufacturing process. Fit is critically important for how dentures feel and function in the mouth. If they are too loose, they become uncomfortable and limit which foods you can eat.

If that weren't enough, recent advancements with dental implants have taken dentures to an entirely new level, beyond anything imaginable in Revere's day. We're now able to create dentures that connect or are permanently affixed to implants set within the jaw, which makes them more stable and secure. An implant-supported denture also helps prevent bone loss, a weakness of traditional dentures, causing them to loosen over time.

As amazing as they are, we wouldn't have the modern version of dentures without craftsmen like Paul Revere who helped advance the cause of dental restoration. So, lift a glass of holiday cheer this season to this hero of the American Revolution—and of American dentistry.

If your teeth could use improvement from discoloration, chips, cracks, gaps, or misalignment, porcelain veneers can transform all of the above. This cosmetic option is suitable for a large portion of patients, but to determine if veneers are appropriate for you, schedule a consultation at Drs. Joseph & Nina Zeigler's dental office in St. Louis, MO, to address your concerns and imperfections. Read on to learn more!

Rejuvenate Your Smile with Porcelain Veneers

Dental veneers are wafer-thin shells of porcelain that match the shade of your natural teeth. Using a minimally invasive irreversible procedure, they cover enamel to correct a variety of dental issues mentioned above. They are highly stained resistant, which means that you can consume your cup of coffee without worry, and show off your smile with confidence. Porcelain veneers also boast protective qualities that can eliminate the need for further dental treatment in the future. Ideal candidates practice good oral hygiene habits, have sufficient tooth enamel, and several cosmetic issues you want to fix.

What to Expect From Treatment

Porcelain veneers typically take up to three visits to our St. Louis office to complete. These include diagnostic and treatment planning, tooth preparation, and bonding—in that order. To begin the procedure, your dentist will administer a local anesthetic to make you comfortable during preparation and placement. The tooth will be minimally reshaped with a small rotational device to ensure the best fit. Your dentist will then make a mold of your teeth before sending it to a laboratory where your permanent veneers are fabricated. During your third visit, they will cement them to the surface of the enamel.

TobaccoOneBaseballTraditionWeCanDoWithout

While sports like football, basketball and soccer have exploded in popularity over the last few decades, many Americans still have a soft spot for the granddaddy of them all: baseball. While technology has changed many aspects of the game, many of its endearing traditions live on.

Unfortunately, one baseball tradition isn’t so endearing and definitely hazardous to health—tobacco, primarily the smokeless variety. Players and coaches alike, even down to the high school level, have promoted or at least tolerated its use.

But there are signs this particular baseball tradition is losing steam. Not long ago, the San Francisco Giants became the first major league baseball team to prohibit tobacco in its home stadium—on the field as well as in the stands. The move was largely in response to a law passed by the City of San Francisco, but it does illustrate a growing trend to discourage tobacco use in baseball.

While smoking, chewing or dipping tobacco can certainly impact a person’s overall health, it can be especially damaging to the teeth, gums and mouth. Our top oral health concern with tobacco is cancer: Research has shown some correlation between tobacco use (especially smokeless) and a higher risk of oral cancer.

You need look no further than the highest ranks of baseball itself to notice a link between tobacco and oral cancer. Although from different eras, Babe Ruth and Tony Gwynn, both avid tobacco users, died from oral cancer. Other players like pitcher Curt Schilling have been diagnosed and treated for oral cancer.

Cancer isn’t the only threat tobacco poses to oral health. The nicotine in tobacco can constrict blood vessels in the mouth; this in turn reduces the normal flow of nutrients and disease-fighting immune cells to the teeth and gums. As a result, tobacco users are much more susceptible to contracting tooth decay and gum disease than non-users, and heal more slowly after treatment.

That’s why it’s important, especially in youth baseball, to discourage tobacco use on the field. While most of baseball’s traditions are worthy of preservation, the chapter on tobacco needs to close.
