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.
One of the best and most successful tooth replacement choices available is the dental implant. No other restorative method is as similar in both form and function to a real tooth as an implant; and with a success rate of 95-plus percent after ten years, it’s one of the most durable.
But there can be extenuating circumstances that make obtaining an implant difficult or sometimes impossible. One possible problematic situation is the systemic disease diabetes.
Diabetes is a hormonal condition in which the body is unable to sufficiently regulate the amount of glucose (a basic sugar that provides energy to the body’s cells) within the blood stream. Normally, the pancreas produces the hormone insulin to reduce excess glucose. But diabetes interferes with this insulin production: if you have Type 1 diabetes, the pancreas has stopped producing insulin altogether; if you have the more common Type 2, the body doesn’t produce adequate insulin or it doesn’t respond sufficiently to the insulin produced.
Over time diabetes can affect other areas of health, especially wound healing. Because the condition gradually causes blood vessels to narrow and stiffen, the normal inflammatory response to disease or trauma can become prolonged. This in turn slows the rate of wound healing.
Slow wound healing can have a bearing on the recovery period just after implant surgery, especially the necessary integration process that takes place between the bone and the titanium metal implant that provides its signature strength. If that process is impeded by slow wound healing caused by diabetes, the risk increases dramatically for implant failure.
That’s the worst case scenario if you have diabetes, but only if your condition is out of control. If, however, you have your blood sugar levels well regulated through medication, diet and exercise, then your chances for implant success could easily be on par with someone without diabetes.
So if you’re diabetic and are considering dental implants for missing teeth, it’s important to discuss the possibility of obtaining them with both your dentist and the physician caring for your diabetes. With your overall healthcare team working together, there’s no reason why diabetes should stop you from enjoying this premiere restoration for missing teeth.

Seven out of ten Americans are missing at least one tooth due to decay, periodontal (gum) disease or injury. Unfortunately, the consequences go far beyond a missing tooth — the loss of even one could set in motion a cascade of problems.
Perhaps the most damaging of these problems is bone loss. Like other living tissue, bone has a life cycle — older cells dissolve (resorb) into the body and are replaced by fresher cells. This growth cycle in the jawbone receives stimulation from forces generated by teeth when we chew or bite. If a tooth is no longer present to provide this stimulation, the affected bone cells won’t regenerate at a healthy rate. Over time this causes the volume of bone to diminish, as much as 25% the first year after tooth loss.
The void left by a missing tooth can also adversely affect remaining teeth. Teeth are held in place by a tough but elastic tissue known as the periodontal ligament that lies between the tooth and the bone. The ligament enables teeth to move gradually in response to mouth changes so that the teeth remain tightly aligned with each other. When there’s a gap from a missing tooth, this tendency will cause the teeth on either side to move (or “drift”) toward the open space. Although a natural phenomena, it can result in a malocclusion (poor bite).
That’s why it’s important to replace a missing tooth with a life-like replica — not just for appearance’s sake, but also to improve function and prevent the rise of these other problems. While many options exist (from removable dentures to fixed bridges) the choice most preferred by dentists and patients is the dental implant.
An implant replaces the tooth root as well as the crown, because it’s imbedded securely into the jawbone. Because of a natural affinity with titanium, the principal metal used in implants, bone cells will grow to its surface. Not only will this anchor the implant more securely, it will slow or even stop bone loss.
If you have a missing tooth, you should visit us as soon as possible to consider your options for a replacement. A new tooth will help stop even greater problems from occurring.

For generations, dentures have helped people avoid the dire consequences of total teeth loss. Now, implant technology is making them even better.
Composed of life-like prosthetic teeth fixed within a plastic or resin gum-colored base, dentures are manufactured to fit an individual patient’s mouth for maximum fit, comfort and performance. But dentures also have a critical drawback—they can’t stop bone loss in the jaw.
Bone is constantly regenerating as older cells dissolve and then are replaced by newer cells. In the jawbone, the forces generated when we chew travel through the teeth to the bone and help stimulate this new cell growth. When teeth are missing, though, the bone doesn’t receive this stimulus and may not regenerate at a healthy rate, resulting in gradual bone loss.
Dentures can’t transmit this chewing stimulus to the bone. In fact, the pressure they produce as they rest on top of the gums may actually accelerate bone loss. Over time then, a denture’s once secure and comfortable fit becomes loose.
In the past, most patients with loose dentures have had them relined with new dental material to improve fit, or have new dentures created to conform to the changed contours of the jaws. But implant technology now offers another alternative.
Implants are in essence a tooth root replacement. Dentists surgically implant a titanium metal post directly into the jawbone that naturally attracts bone cells to grow and adhere to it over time (a process called osseointegration). This not only creates a secure and lasting hold, it can also stop or even reverse bone loss.
Most people know implants as single tooth replacements with a porcelain crown attached to the titanium post. But a few strategically placed implants can also support either removable or fixed dentures. Removable dentures (also called overdentures) usually need only 3 or 4 implants on the top jaw and 2 on the bottom jaw for support through built-in connectors in the dentures that attach to the implants. A fixed bridge may require 4-6 implants to which they are permanently attached.
There are pros and cons for each of these options and they’re both more expensive than traditional dentures. In the long run, though, implant-supported dentures could be more beneficial for your bone health and hold their fit longer.
Dental implants are by far the best way to replace missing teeth. But they do more than improve your smile: they can restore your ability to eat, chew and talk properly, especially if the teeth replaced are in the back of your mouth. What’s more, they can improve the entire look of your face by restoring facial height and cheek support lost because of the missing teeth.
There is, however, one obstacle to overcome before receiving dental implants — a lack of sufficient bone at the implant site. Bone loss usually occurs when teeth have been missing for some time. This is because when we chew the forces generated by the teeth stimulate continual bone growth to make up for older bone that has dissolved (resorbed). This stimulation doesn’t occur after teeth are lost, which slows the rate of bone growth. Over time the amount of healthy bone diminishes.
Without enough bone for support, implants can’t be placed properly. Fortunately, some of the bone can be regenerated through techniques that place bone grafting material at the site to stimulate and serve as a scaffold for new bone.Â The new bone will eventually replace the graft.
For missing upper back teeth with bone loss, we can take advantage of facial anatomy to grow the bone needed for implants. This area of the face is where the maxillary sinuses, air spaces lined with a tissue membrane, are located on either side just above the upper jaw. After determining their exact size and location through detailed x-ray imaging, we can surgically access the area inside the mouth just above the missing teeth.
The sinus cavity is an area where bone growth can occur by placing a bone graft between the floor of the sinus and the sinus membrane. Sometimes bone growth enhancers are used to stimulate and speed up regeneration. The procedure can usually be performed with local anesthesia (much like a routine tooth filling), with only mild discomfort afterward for a few days managed by an anti-inflammatory drug like ibuprofen and a decongestant for sinus swelling.
After six to seven months, we re-evaluate the area to see if sufficient bone has returned for implant surgery. If so, you will be well on your way to achieving a new look and better function through dental implants.
