People who’ve lost all their teeth (a condition known as edentulism) face a decision on how to restore their lost function and appearance. And there are a number of options to consider.
A fixed bridge supported by dental implants, for example, is a good choice for patients who still have sufficient bone structure in their jaw. It’s not a good choice, however, for those with the opposite situation — who’ve experienced significant bone loss which has also affected their facial structure. For them, there’s a better alternative that also uses implants for support — the overdenture.
An overdenture is similar to a traditional denture, in that it’s made of life-like crowns permanently set in denture plastic, and may either partially or fully cover the roof of the mouth. The main difference, though, is that unlike traditional dentures which rest for support on the gum ridges, an overdenture is supported by strategically placed implants that the denture fits over and connects to — hence the name “overdenture.”
There are a number of advantages for an overdenture, especially for patients with bone loss. A removable, implant-supported denture can be designed to replace lost tissues that have altered facial appearance — to “fill in” the face and restore aesthetic harmony. Patients who’ve previously worn dentures will also often find their speech better improved than with fixed bridgework.
Because it’s removable, an overdenture and the underlying gums are easier to clean, which helps inhibit disease and lessen further bone loss. It also allows you to properly care for the denture, which can extend its longevity and reduce future potential maintenance and replacement costs.
If you would like to consider removable overdentures as an option, you should begin first with a thorough oral exam that includes evaluating the status of your bone, jaw and facial structure. From there we can advise you if overdentures are the best choice for you.

Dental implants are best known as restorations for single missing teeth. But there’s more to them than that—they can also be used to support and secure removable dentures or fixed bridges.
That’s because a dental implant is actually a root replacement. A threaded titanium post is inserted directly into the jawbone where, over time, bone cells grow and adhere to it. This accumulated bone growth gives the implant its signature durability and contributes to its long-term success rate (95%-plus after ten years). It can support a single attached crown, or serve as an attachment point for a dental bridge or a connector for a removable denture.
The method and design of implants differentiates it from other restoration options. And there’s one other difference—implants require a minor surgical procedure to insert them into the jawbone.
While this might give you pause, implant surgery is no more complicated than a surgical tooth extraction. In most cases we can perform the procedure using local anesthesia (you’ll be awake the entire time) coupled with sedatives (if you have bouts of anxiety) to help you relax.
We first access the bone through small incisions in the gums and then create a small channel or hole in it. A surgical guide that fits over the teeth may be used to help pinpoint the exact location for the implant.
We then use a drilling sequence to progressively increase the size of the channel until it matches the implant size and shape. We’re then ready to insert the implant, which we remove at this time from its sterile packaging. We may then take a few x-rays to ensure the implant is in the right position, followed by closing the gums with sutures.
There may be a little discomfort for that day, but most patients can manage it with over-the-counter pain relievers like aspirin or ibuprofen. It’s what goes on over the next few weeks that’s of prime importance as the bone grows and adheres to the implant. Once they’re fully integrated, we’re ready to move to the next step of affixing your crown, bridge or denture to gain what you’ve waited so long for—your new implant-supported smile.

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.
Dental implants are considered today’s premier method for restoring missing teeth. Obtaining an implant, though, is often a long process and the implants themselves must be surgically placed within the jaw bone. Nothing to worry about, though: implant surgery is a minor to moderate procedure akin to a surgical tooth extraction.
Still like any surgery, this procedure does involve cutting into the soft tissues of the gums and could allow oral bacteria to enter the bloodstream. While most bacteria in the mouth are harmless (and even beneficial) a few strains can cause disease. For some people, especially those with certain heart conditions or joint replacements, this could potentially cause serious issues in other parts of their body that might be highly susceptible to infection.
To guard against this, it’s been a long-standing practice in dentistry to prescribe antibiotics to certain high risk patients before a procedure. Although this departs from the normal use of antibiotics for already occurring infections, due to the circumstances this has been deemed an acceptable measure to prevent disease.
In the past, the categories of patients for which preventive antibiotics were appropriate had been more extensive. In recent years, though, both the American Dental Association and the American Heart Association have adjusted their recommendations. Today, your dental provider may recommend antibiotic pre-treatment if you have a prosthetic (artificial) heart valve, a history of infective endocarditis (inflammation of the inner linings of the heart), a heart transplant or certain congenital heart conditions.
While physicians may still recommend premedication with antibiotics for patients with joint replacements, it’s not as blanket a standard as it might once have been. It’s now only recommended for certain cases, such as patients who’ve received a prosthetic joint within the last two years.
There’s still an ongoing debate about the effectiveness of antibiotic pre-medication. However, there’s evidence medicating before procedures with antibiotics can be beneficial in avoiding infection. If you fall into one of the categories just mentioned or are concerned about infection, feel free to discuss with your dentist if using antibiotics before your implant surgery is wise move for you.

Since their introduction over three decades ago, dental implants have evolved into dentistry’s premier tooth replacement choice. While their primary purpose is to replace missing teeth and rejuvenate a patient’s smile, they’re also regarded for another important benefit: they can slow or stop bone loss accelerated by the loss of teeth.
Like all living tissue, bone has a life cycle. Older bone dissolves and is absorbed by the body, a process called resorption. New bone forms and grows to replace the resorbed bone in response to stimuli occurring within the body. In the jaw, this stimulation comes from the forces the teeth receive when we bite or chew.
When a tooth is lost, however, it no longer transmits these force stimuli to the adjacent bone. This results over time in less new growth to replace resorbed bone, and the overall bone mass shrinks. In fact, about a quarter of the normal bone width will diminish in the first year alone after tooth loss. Other serious problems follow, like gum recession or chewing and speaking difficulties. A person’s appearance may also suffer, because as resorption continues unchecked, the underlying foundational bone will continue to shrink. As more teeth are lost, a decrease in the distance between the nose and chin may result causing the lower third of the face to become smaller in size.
Dental implants can interrupt this process by encouraging bone growth around the implant. Implants are made of “osseophilic” titanium, meaning the metal has a natural affinity with bone. After implantation, bone cells will begin to grow and attach to the titanium post. The enhanced growth stabilizes bone loss by providing stimulation to the bone as teeth once did, thereby maintaining bone levels and minimizing potential effects on the patient’s appearance.
Ironically, too much bone loss could make the installation of implants more difficult, since they require a minimum level of bone mass for anchorage. Receiving an implant as soon as is practical once a tooth is lost will minimize the chances of that occurring — and a better chance of improving bone health overall.
