While tooth loss can occur at any age, replacing one in a younger patient requires a different approach than for someone older. It’s actually better to hold off on a permanent restoration like a dental implant if the person is still in their teens.
This is because a teenager’s jaws won’t finish developing until after nineteen or in their early twenties. An implant set in the jawbone before then could end up out of alignment, making it appear out of place — and it also may not function properly. A temporary replacement improves form and function for now and leaves the door open for a permanent solution later.
The two most common choices for teens are a removable partial denture (RPD) or a bonded fixed bridge. RPDs consist of a plastic gum-colored base with an attached prosthetic (false) tooth matching the missing tooth’s type, shape and jaw position. Most dentists recommend an acrylic base for teens for its durability (although they should still be careful biting into something hard).
The fixed bridge option is not similar to one used commonly with adult teeth, as the adult version requires permanent alteration of the teeth on either side of the missing tooth to support the bridge. The version for teens, known as a “bonded” or “Maryland bridge,” uses tiny tabs of dental material bonded to the back of the false tooth with the extended portion then bonded to the back of the adjacent supporting teeth.
While bonded bridges don’t permanently alter healthy teeth, they also can’t withstand the same level of biting forces as a traditional bridge used for adults. The big drawback is if the bonding breaks free a new bonded bridge will likely be necessary with additional cost for the replacement.
The bridge option generally costs more than an RPD, but buys the most time and is most comfortable before installing a permanent restoration. Depending on your teen’s age and your financial ability, you may find it the most ideal — though not every teen is a good candidate. That will depend on how their bite, teeth-grinding habits or the health of surrounding gums might impact the bridge’s stability and durability.
A complete dental exam, then, is the first step toward determining which options are feasible. From there we can discuss the best choice that matches your teen’s long-term health, as well as your finances.
The U.S. Centers for Disease Control and Prevention calls it “one of the ten most important public health measures of the 20th Century.” A new vaccine? A cure for a major disease? No—the CDC is referring to the addition of fluoride to drinking water to prevent tooth decay.
Fluoride is a chemical compound found in foods, soil and water. Its presence in the latter, in fact, was key to the discovery of its dental benefits in the early 20th Century. A dentist in Colorado Springs, Colorado, whose natural water sources were abundant with fluoride, noticed his patients' teeth had unusual staining but no tooth decay. Curious, he did some detective work and found fluoride in drinking water to be the common denominator.
By mid-century, fluoride was generally recognized as a cavity fighter. But it also had its critics (still lively today) that believed it might also cause serious health problems. Ongoing studies, however, found that fluoride in tiny amounts—as small as a grain of sand in a gallon of water—had an immense effect strengthening enamel with scant risk to health.
The only condition found caused by excess fluoride is a form of tooth staining called fluorosis (like those in Colorado Springs). Fluorosis doesn't harm the teeth and is at worst a cosmetic problem. And it can be avoided by regulating the amount of ingested fluoride to just enough for effectively preventing tooth decay.
As researchers have continued to learn more about fluoride, we've fine-tuned what that amount should be. The U.S. Public Health Service (PHS), which sets standards for fluoride in drinking water, now recommends to utilities that fluoridate water to do so at a ratio of 0.7 mg of fluoride to 1 liter of water. This miniscule amount is even lower than previous recommendations.
The bottom line: Fluoride can have an immense impact on your family's dental health—and it doesn't take much. Excessive amounts, though, can lead to dental staining, so it's prudent to monitor your intake. That means speaking with your dentist about the prevalence of fluoride in your area (including your drinking water) and whether you need to take measures to reduce (or expand) your use of it.

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.
