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.
Ed Helms is best known for his role as the self-absorbed, Ivy League sales rep, Andy Bernard, on television's The Office. But to millions of fans he's also Stu, a member of a bachelor trip to Las Vegas in the 2009 movie The Hangover. In it, Stu and his friends wake up from a wild night on the Strip to find some things missing: the groom-to-be, their memories and, for Stu, a front tooth.
In reality, the missing tooth gag wasn't a Hollywood makeup or CGI (computer-generated imagery) trick—it was Ed Helm's actual missing tooth. According to Helms, the front tooth in question never developed and he had obtained a dental implant to replace it. He had the implant crown removed for the Hangover movie and then replaced after filming.
Helms' dental situation isn't that unusual. Although most of the 170 million-plus teeth missing from Americans' mouths are due to disease or trauma, a few happened because the teeth never formed. While most of these congenitally missing teeth are in the back of the mouth, a few, as in Helms' case, involve front teeth in the “smile zone,” which can profoundly affect appearance.
Fortunately, people missing undeveloped teeth have several good options to restore their smiles and dental function. The kind of tooth missing could help determine which option to use. For example, a bridge supported by the teeth on either side of the gap might work well if the teeth on either side are in need of crowns.
If the missing tooth happens to be one or both of the lateral incisors (on either side of the centermost teeth), it could be possible to move the canine teeth (the pointy ones, also called eye teeth) to fill the gap. This technique, known as canine substitution, may also require further modification—either by softening the canines' pointed tips, crowning them or applying veneers—to help the repositioned teeth look more natural.
The optimal solution, though, is to replace a missing tooth with a dental implant which then has a lifelike crown attached to it, as Ed Helms did to get his winning smile. Implant-supported replacement teeth are closest to natural teeth in terms of both appearance and function. Implants, though, shouldn't be placed until the jaw has fully developed, usually in early adulthood. A younger person may need a temporary restoration like a bonded bridge or a partial denture until they're ready for an implant.
Whatever the method, there's an effective way to restore missing teeth. Seeing us for an initial exam is the first step toward your own winning smile.
While many people still consider dental implants the "new kids on the block" in dental restoration, they're now in their fourth decade of use. And since their inception implant technology has continued to improve and revolutionize how we replace missing teeth.
Implants are a different "species" compared to other restoration methods. To be precise, an implant is a tooth root replacement—usually a titanium metal post imbedded directly into the jaw bone. Titanium is not only a biocompatible metal, but bone cells naturally grow on its surface to create a strong and durable hold. It's this secure hold that's most responsible for implants' high long-term success rate.
But we should also credit some of this success to the steady stream of advances over the years in implant construction and supporting technologies. For one thing, we're now more accurate and precise with implant placement thanks to advances in computer tomography (CT) and cone beam CT (CBCT) scanning.
These digital processes merge a series of images taken by a special camera to form a three-dimensional model of the jaw. We can manipulate this model on a computer monitor to view it from different vantage points. It can help us locate and avoid anatomical structures like nerves and sinuses when determining where to place a future implant. CT and CBCT are especially useful when there's a concern about adequate available bone, a necessity for stable implants.
Technology has also improved how we create surgical guides, often used during implant surgery to obtain the most accurate results. Surgical guides are custom-made devices that fit over the teeth with the drilling locations for the implants marked on them. Recent advances in 3-D printing have made these guides even more accurate so that they fit more securely in the mouth. This greater stability increases their accuracy during the drilling sequence during surgery.
These and other advances are helping ensure every implant is a success story. The end result is both a functional restoration and a beautiful smile.

Are you interested in dental implants but a little hesitant about the surgery? Don’t be—this procedure to imbed an implant’s titanium post in the jawbone is relatively minor with little to no discomfort for most patients.
Some time before, however, we’ll need to pre-plan the surgery to pinpoint the best location for the implant, critical to achieving a solid hold and a life-like appearance. During these first visits we often create a surgical guide, a device inserted in the mouth during surgery that identifies the exact location for the hole (or channel) in the bone we’ll drill to insert the implant.
On surgery day, we’ll prepare you for a pain-free and relaxing experience. If you’re normally anxious about dental work, we may prescribe a sedative for you to take ahead of time. As we begin we’ll thoroughly numb the area with local anesthesia to ensure you won’t feel any pain.
The surgery begins with an incision through the gum tissue to access the underlying bone. Once it’s exposed, we’ll insert the surgical guide and begin a drilling sequence to gradually increase the size of the channel. This takes time because we want to avoid damaging the bone from overheating caused by friction.
Once we’ve created a channel that matches precisely the implant’s size and shape, we’ll remove the implant from its sterile packaging and immediately fit and secure it in the channel. We’ll then take x-rays to ensure it’s in the best position possible.
Satisfied we’ve properly situated and secured the implant, we’ll suture the gum tissue back in place to protect the implant with or without attaching a healing abutment to it as it fully integrates with the jawbone over the next few months (after which you’ll come back to receive your permanent crown). After a short recovery, you’ll return to full activity. Most patients only experience mild to moderate discomfort usually manageable with over-the-counter pain medication like aspirin or ibuprofen.
While implantation is a long process, you’ll be obtaining what’s considered by most dentists and their patients as the most durable and life-like tooth replacement available. Your new attractive smile will be well worth it.

Every year dentists place over 5 million dental implants for lost teeth, often removing the problem tooth and installing the implant at the same time. But getting a “tooth in a day” depends on a number of health factors, especially whether or not there’s adequate bone available for the implant. Otherwise, the implant’s placement accuracy and success could be compromised.
Bone loss can be a similar problem when a tooth has been missing for a long period of time. If this describes your situation, you may have already lost substantial bone in your jaw. To understand why, we need to know a little about bone’s growth cycle.
When bone cells reach the end of their useful life, they’re absorbed into the body by a process called resorption. New cells then form to take the older cells’ place in a continuous cycle that keeps the bone healthy and strong. Forces generated when we chew travel through the teeth to the bone and help stimulate this growth. But when a tooth is missing, the bone doesn’t receive this stimulus. As a result, the bone may not replace itself at a healthy rate and diminish over time.
In extreme cases, we may need to consider some other dental restoration other than an implant. But if the bone loss isn’t too severe, we may be able to help increase it through bone grafting. We insert safe bone grafting material prepared in a lab directly into the jaw through a minor surgical procedure. The graft then acts like a scaffold for bone cells to form and grow upon. In a few months enough new bone may have formed to support an implant.
Bone grafting can also be used if you’re having a tooth removed to preserve the bone even if you’re not yet ready to obtain an implant. By placing a bone graft immediately after extraction, it’s possible to retain the bone for up to ten years—enough time to decide on your options for permanent restoration.
Whatever your situation, it’s important that you visit us as soon as possible for a complete examination. Afterward we can assess your options and hopefully come up with a treatment strategy that will eventually include smile-transforming dental implants.
