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.
You’ve probably heard a lot about dental implants as replacements for missing teeth. So, why are they so popular with both patients and dentists? While other restorations can mimic the color, shape and texture of natural teeth, dental implants have one clear advantage — and it’s all about the bone.
The bone in your jaws provides stability and structure for teeth — without it and the intricate system of gum tissue attachments teeth couldn’t survive the normal biting and chewing forces they encounter every day. That’s why bone health is crucial for maintaining tooth integrity.
Teeth also help bone to remain strong and healthy. The forces we generate as we chew transmit through the tooth roots to the bone, which stimulates continuing growth. If a tooth is missing, however, the bone around it doesn’t receive this stimulation and may begin to lose some of its volume and density — up to a quarter of its width in just the first year after tooth loss.
This bone loss continues even with other restorations because they’re not able to stimulate bone growth. But dental implants can. This is because the portion of the implant imbedded into the bone is constructed most often of titanium, which has a natural affinity toward bone. Bone cells are naturally attracted to titanium and will begin to grow and attach to the metal surface, a process known as osseointegration.
Through osseointegration, the implant develops a durable bond with the jawbone a few weeks after surgery that surpasses other restorations, and is a prime reason for their success rate. Although installing implants can be an expensive undertaking, their proven longevity may result in less maintenance, repair or replacement costs over time than other replacement options.
If you’re considering dental implants, remember it’s what you can’t see beneath the attractive crown that makes them special. And it’s a choice you can depend on to provide you a beautiful smile for years to come.

You’re considering dental implants and you’ve done your homework: you know they’re considered the best tooth replacements available prized for durability and life-likeness. But you do have one concern — you have a metal allergy and you’re not sure how your body will react to the implant’s titanium and other trace metals.
An allergy is the body’s defensive response against any substance (living or non-living) perceived as a threat. Allergic reactions can range from a mild rash to rare instances of death due to multiple organ system shutdowns.
A person can become allergic to anything, including metals. An estimated 17% of women and 3% of men are allergic to nickel, while 1-3% of the general population to cobalt and chromium. While most allergic reactions occur in contact with consumer products (like jewelry) or metal-based manufacturing, some occur with metal medical devices or prosthetics, including certain cardiac stents and hip or knee replacements.
There are also rare cases of swelling or rashes in reaction to metal fillings, commonly known as dental amalgam. A mix of metals — mainly mercury with traces of silver, copper and tin — dental amalgam has been used for decades with the vast majority of patients experiencing no reactions. Further, amalgam has steadily declined in use in recent years as tooth-colored composite resins have become more popular.
Which brings us to dental implants: the vast majority are made of titanium alloy. Titanium is preferred in implants not only because it’s biocompatible (it “gets along” well with the body’s immune system), but also because it’s osteophilic, having an affinity with living bone tissue that encourages bone growth around and attached to the titanium. Both of these qualities make titanium a rare trigger for allergies even for people with a known metal allergy.
Still, implant allergic reactions do occur, although in only 0.6% of all cases, or six out of a thousand patients. The best course, then, is to let us know about any metal allergies you may have (or other systemic conditions, for that matter) during our initial consultation for implants. Along with that and other information, we'll be better able to advise you on whether implants are right for you.

You may be familiar with a dental implant used to replace a single tooth — but implant technology can do much more. Implants can also support other restorations including total teeth replacement on a jaw.
The reason they're so versatile is because implants replace the tooth root as well as the visible crown. We use a metal post, usually made of titanium, which we surgically implant in the jawbone as a root substitute. Because of a special affinity with titanium, bone around the implant grows and adheres to it and creates a durable bond.
With a single tooth replacement (the implant's original purpose when they were introduced in the 1980s) we attach a life-like porcelain crown to the individual titanium post. But with their continuing development we've adapted implants for other applications, like using a few strategically-placed implants as a stable platform for removable dentures or fixed bridges.
We're now able to use implants to support a full prosthetic (false) dental arch. Though similar in appearance to a removable denture, this particular prosthesis is permanently joined to the supporting implants with retaining screws.
Of course, the application requires careful pre-planning, which includes making sure you have enough healthy bone to support the implants. We'll also need to determine how many implants you'll need (usually four to six for this application) and create a surgical guide to place them in the best location for supporting the prosthesis. A dental technician will then create the prosthesis to match your jaw ridge contours and facial structure.
Using implants this way has a benefit other types of restorations can't provide: they may help stop future bone loss. The jawbone life cycle depends on stimulation from the attached tooth as you bite and chew — stimulation that ends when you lose the tooth. Traditional dentures and other restorations can't replicate that stimulation. Implants, on the other hand, directly encourage bone growth and can stop gradual bone loss.
If you need some form of total teeth replacement, consider one supported by implants. You may find they'll provide an excellent long-term solution to both function and appearance.
First introduced in the 1980s, dental implants are a popular and reliable tooth replacement option. Numerous studies show that after ten years 95% are still in place. Much of this success owes to the implant’s titanium post imbedded directly into the jaw, which then attracts bone growth. This additional growth securely anchors the implant in place for an unrivaled durability among other replacement options.
Still, a small percentage of implants fail — some in the first few months and others after a few years. Here are 3 reasons why, and how you can overcome them.
Poor bone quantity and quality. Implants need a certain amount of existing bone to succeed. Sometimes, though, there isn’t enough because prolonged absence of a tooth causes bone loss around the empty socket. Conditions like diabetes, osteoporosis or tobacco use can also compromise bone health. It’s often possible to increase bone volume with grafting, especially right after tooth extraction.
Teeth grinding habits. This occurs when you unconsciously grind or clench your teeth, usually during sleep. The habit can create forces far in excess of what’s normal when we bite or chew and can damage or even break the crown attached to an implant. Besides reducing stress (a major factor for teeth grinding), you can also alleviate the abnormal force generated by wearing a night guard.
Periodontal (gum) disease. Although your implants are impervious to disease or infection, supporting gums and bone aren’t. Plaque, a film of food and bacteria that builds up on tooth surfaces, can cause gum disease that weakens the supporting tissues (gums and bone) of the implant. This can give rise to a specific condition with implants known as peri-implantitis where the infected gum tissues and bone around it deteriorate, leading to the implant’s catastrophic loss. To avoid this, practice consistent daily hygiene, including around the implant. And see us regularly for checkups and cleanings, or as soon as possible if you see signs of gum problems.
