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 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.
Dental implant technology has advanced at such an astounding rate in recent years that you can now walk into a dentist's office with a problem tooth and out the same day with a new one. Unfortunately, not all dental situations allow for this possibility.
For example, you might be considering an implant many years after losing a tooth. But there's a potential problem: there might not be enough supporting bone. While an implant might still be possible, inadequate bone complicates the matter.
Because implants are essentially tooth root replacements, they require a certain amount of bone for stability and the best attractive outcome. As a general rule, implants need to be surrounded by at least 1.5-2.0 millimeters of healthy bone to support an implant. But you might not have enough if your tooth has been missing for awhile, regardless if you have or haven't worn dentures or other restorations.
That's because bone has a life cycle in which older cells die and newer ones form to take their place. As we chew or bite, the force generated travels up through the teeth to the bone to stimulate this new growth. Without a tooth the bone doesn't receive this stimulus, which can slow the growth rate. Over time the affected bone can lose its volume and density.
If we find you've experienced loss to the point your bone won't support an implant, that doesn't automatically mean this popular restoration is out of the picture. But it will require us first performing a procedure known as augmentation or bone grafting to help rejuvenate some of the lost bone.
With grafting, we place processed bone grafting material in the jaw through a minor surgical procedure to form a scaffold for new bone to grow upon. After several months this can result in several millimeters of new growth maintaining the width of the underlying bone, which in turn may be able to support an implant.
Bone grafting is quite common, often performed at the same time as tooth extraction if there's going to be a time lag before installing an implant. Even if performed later, though, it can successfully rejuvenate lost bone and make it possible for you to take advantage of durable, life-like implants.

You probably already know that using tobacco causes significant health risks: It increases your odds of getting various cancers and coronary diseases, to name just a few. Unfortunately, not everyone is able to kick the habit, even when they know they should. Tooth loss is another issue that can cause trouble for your health, in the form of bone loss, malnutrition, and social or psychological problems. Dental implants are a great way to replace missing teeth — but does smoking complicate the process of getting implants?
The short answer is yes, smoking can make implant placement a bit riskier — but in the big picture, it doesn’t mean you can’t (or shouldn’t) have this procedure done if it’s needed.
Smoking, as you know, has harmful effects in your mouth (even leaving aside the risk of oral cancer). The hot gases can burn the oral cavity and damage salivary glands. Nicotine in smoke reduces blood flow to the soft tissues, which can affect the immune response and slow the processes of healing. At the same time, smoking promotes the growth of disease-causing oral bacteria.
How does this affect dental implants? Essentially, smoking creates a higher risk that implants may not heal properly after they are placed, and makes them more likely to fail over time. Studies have shown that smokers have an implant failure rate that’s twice as great as non-smokers. Does this mean that if you smoke, you shouldn't consider implants to replace missing or failing teeth?
Not necessarily. On the whole, implants are the most successful method of replacing missing teeth. In fact, the overall long-term survival rate of implants for both smokers and non-smokers is well over 90 percent — meaning that only a small percentage don’t work as they should. This is where it’s important to get the expert opinion of an implant specialist, who can help you decide whether implants are right for your particular situation.
If you do smoke, is there anything you can do to better your odds for having a successful dental implant? Yes: quit now! (Implants are a good excuse to start a smoking-cessation program.) But if you can’t, at least stop smoking for one week before and two weeks after implant placement. And if that is not possible, at least go on a smoking diet: restrict the number of cigarettes you smoke by 50% (we know you can at least do that!) Try to follow good oral hygiene practices at all times, and see your dentist regularly for checkups and cleanings.
If you’re in the initial planning stages for a dental implant, you may already be encountering a number of options to consider. One that may come up is how the visible crown will attach to the metal implant imbedded in the bone.
Generally speaking, implants are composed of two parts: a metal post most often made of titanium placed into the bone that serves as the “root” for the new tooth; and a visible, life-like crown made of dental porcelain that attaches to an abutment on the titanium post. The crown can be attached in one of two ways: either with a small screw through the biting surface of the crown into a receiving hole in the abutment or cemented to it.
The major advantage of a screwed crown is that it allows for easy removal of the crown if needed. While the titanium post can often last a lifetime, porcelain crowns more often need repair or replacement since they receive the brunt of the biting forces in the mouth. A screw-attached crown is much easier to remove than a cemented one.
On the other hand, screwed crowns have a small access hole that must be restored with a tooth-colored filling to help the crown appear natural. This isn’t too great an issue with back teeth but does make achieving a natural appearance in the front more difficult. Cemented crowns look more like a natural tooth and are thus more flexible in achieving the desired appearance.
Besides the possibility the cement may cause gum inflammation or bone loss, the chief detraction from cemented crowns is the difficulty in removing them. Crowns are often damaged in this process so it’s highly likely it will have to be replaced rather than repaired. It’s possible to use weaker cement, but this raises the risk of the crown coming loose at some point from the abutment.
As we plan for your implant, we’ll discuss which type of attachment will work best for you, depending on the tooth to be replaced and other conditions with your oral health. The end result, though, should be the same — a new, natural-looking tooth that serves you well for many years to come.
