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 have a lot of options for replacing missing teeth, from state-of-the-art dental implants to affordable, but effective partial dentures. But if the teeth in question have been missing for a while, you may first have to undergo orthodontic treatment. Here's why.
While they may feel rigid and firm in the jawbone, teeth are actually held in place by periodontal (gum) ligaments. These elastic tissues lie between the teeth and the bone and attach to both with tiny filaments. This mechanism allows the teeth to incrementally move over time in response to biting pressures or other environmental factors.
When a tooth goes missing the teeth on either side of the space naturally move or "drift" into it to help close the gap. This natural occurrence can reduce the space for a restoration if it has gone on for some time. To make room for a new prosthetic (false) tooth, we may have to move the drifted teeth back to where they belong.
If you're thinking metal braces, that is an option—but not the only one. Clear aligners are another way to move teeth if the bite problem (malocclusion) isn't too severe. Aligners are a series of custom-made, clear, plastic trays worn over the teeth. The patient wears each tray, slightly smaller than the previous one in the series, for about two weeks before changing to the next one. The reduction in size gradually moves teeth to their intended target position.
Many adults prefer clear aligners because they're nearly invisible and don't stand out like metal braces. They're removable, so you can take them out for cleaning or for special occasions. And, we can also attach a prosthetic tooth to the tray that temporarily covers the missing tooth space.
Whichever orthodontic treatment you choose, once completed we can then proceed with restoration to permanently replace your missing teeth. While it can be a long process, the end result is a beautiful smile that could last for years to come.

Dental implants are today’s closest restorative facsimile to natural teeth. And they’re versatile: not only can they replace single teeth but they can also support bridges or dentures.
But since one of their crucial components is made of metal, are you out of luck obtaining this state-of-the-art dental restoration if you have a metal allergy?
The answer is: probably not—it’s rare for implants to cause an allergic reaction. Still, metal allergies can be a potential problem within your mouth as with other areas of health.
An allergy originates from the body’s necessary response to potentially harmful microorganisms or substances. Sometimes, however, this response becomes chronic and exaggerated, creating an allergy. People can have allergies to nearly anything with responses ranging from a minor rash to a potentially life-threatening multi-organ system shutdown (anaphylactic shock).
A small number of people have allergies to particular metals. One of the most common is nickel, which affects an estimated 17% of women and 3% of men; cobalt and chromium are also known to cause allergies. Consumer exposure, particularly metal contact with the skin through jewelry or clothing, is the most prevalent, but not the most concerning. That’s reserved for metal allergies related to medical devices like coronary stents or hip and knee prostheses. And in dentistry, there are rare occasions of inflammation or rashes from metal amalgam fillings.
Which brings us to dental implants: the main metal post that’s inserted into the jawbone is usually made of titanium. It’s the metal of choice for two reasons: it’s bio-compatible, meaning the body normally accepts its presence; and it’s osteophilic, which means bone cells readily grow and adhere to it, a major reason for implant durability.
While it’s possible for someone to have an allergy and subsequent reaction to implants with titanium, the occurrences appear to be extremely low. In one study of 1,500 patients, titanium allergies were estimated to be a factor in implant failures in less than 1% of those studied.
Even so, if you have known metal allergies you should make sure your dentist knows. Being aware of all the facts will help them recommend the best tooth replacement choice for you—and hopefully it will be dental implants.

Dental implants to replace teeth are a popular choice as much for their durability as their life-likeness. Most implants last for decades, which can result in lower long-term maintenance costs than other replacement options.
But to achieve this longevity, you must take care of your implants. You should brush and floss them daily right along with your remaining natural teeth — and continue regular semi-annual dental visits for cleanings and checkups.
You may be wondering, though: if they're made of inorganic materials, why worry with brushing them? It's true that bacterial plaque, the thin film of food particles most responsible for dental disease, doesn't affect them.
Your implants, though, don't exist in a bubble: they're imbedded in real bone, surrounded by real gum tissue and placed next to real teeth. All these other living tissues are susceptible to infection caused by plaque, even from plaque on non-organic implants.
The bone and tissues around an implant can even have a higher susceptibility to infection. This is because an implant's attachment in the jaw differs from that of natural teeth. An implant is imbedded directly into the bone; a natural tooth, on the other hand, maintains its hold through an elastic gum tissue between it and the bone called the periodontal ligament. Tiny fibers from the ligament attach to the tooth on one side and to the bone on the other.
Besides holding the tooth in place, the ligament also contains blood vessels that supply the tooth and surrounding tissues not only with nutrients but also antibodies that help fight infection. Due to the absence of a ligament connection, an implant doesn't enjoy the same level of protection from infection. Â It's much easier for tissues and teeth around an implant to become infected, and harder to stop it.
That's why prevention through daily hygiene is so important. So, be sure to brush and floss all your teeth — including implants — every day, and keep up your regular dental visits. And at the first sign of a possible infection — swollen, red or bleeding gums — see us as soon as possible for an examination.
Consider your implants a long-term investment in both your smile and dental health. Taking care of them will pay dividends for many years to come.

You've seen the ads for obtaining a new tooth in one day with a dental implant. Those aren't exaggerated claims — you can leave the dental office the same day with a new tooth that looks and functions like the old one.
But the dramatic marketing aside, there is a bit more to the story. Same day tooth replacement isn't appropriate in every situation. And even when it is, there are risks for failure.
We can minimize those risks, however, by focusing on certain goals during the three distinct phases in the process: removing the natural tooth; placing the metal implant into the jawbone; and affixing the visible, crown.
It's crucial during tooth extraction that we avoid damaging the socket bone that will ultimately support the implant's titanium post. If the socket walls break down it could set up future gum recession or cause us to abort the implant procedure altogether that day.
When placing the implant, we want to focus on achieving a strong hold. Due to its special affinity with titanium, bone cells gradually grow and adhere to the post to firmly anchor the implant in time. But since we're immediately loading a crown rather than allowing the bone to fully integrate first, we need to ensure the implant has a secure hold from the get-go. We can only achieve this with precise placement based on careful examination and planning, as well as adequate bone.
Even so, the implant still needs to integrate with the bone for a lasting hold, and that takes time. Even with normal biting forces the implant risks damage during this integration period. That's why we place a temporary crown a little shorter than the surrounding teeth. Those adjacent teeth will take the brunt of the biting force and not the implant.
Once the bone has fully integrated, we'll replace the temporary crown with a permanent one the proper height proportional to the other teeth. Even with the temporary crown, though, you'll still have a life-like tooth the day we removed the older one.
The key to success is planning — first determining if you meet the criteria for a same-day implant and then mapping out and carefully executing each succeeding step. Doing this will ensure your same-day implant is a success from day one.
