Waiting is part of life for a teenager: waiting to get a driver’s license, to graduate high school or to leave home and stretch their wings. A teenager with lost teeth may also need to wait until they’re older to obtain dental implants.
The reason arises from the differences in how implants and natural teeth attach to the jaw. Although natural teeth may seem rigidly set in the bone, they’re actually held in place by an elastic tissue between them and the bone known as the periodontal ligament. Tiny filaments that attach to the teeth on one side and the bone on the other hold the teeth in place, but also allow the teeth to move gradually in response to mouth changes.
A titanium implant post doesn’t have this relationship with the periodontal ligament — it’s attached directly to the jaw bone. Over time the bone, which has a special affinity with titanium, grows and adheres to it to form a durable bond without an attachment to the periodontal ligament. Because of this the implant can’t move like a natural tooth.
This is extremely important for implant placement because the jaws in particular won’t fully develop in most people until their late teens or early twenties: the upper jaw in particular will tend to grow out and down. Natural teeth accommodate to these changes, but the implant can’t — it will appear to retreat into the jaw. The gum tissues surrounding the implant also won’t conform to the continuing growth and may appear receded.
The best approach is to choose a temporary replacement option until the jaws and other facial bone structures have finished growing. One example is a bonded bridge in which we use a bonding agent to attach a bridge of artificial teeth to teeth on either side of a missing tooth — bonding won’t permanently alter them as with a traditional bridge. Once the jaws have finished growing, we can remove the bonded bridge and install the more permanent implant.
Ask any teenager: waiting can be hard. But with dental implants, waiting until the right time will help ensure the attractive result is a permanent one.

We've been using bridges to replace missing teeth for decades. Now, recently-developed implant-supported bridges are even more dependable, promising greater durability and less interference with remaining natural teeth.
But just like other restorations, you'll need to keep implant bridges clean to ensure their longevity. Although both the bridge and implants are impervious to disease, the supporting gums and bone aren't. If they become infected, they can break down and your restoration will fail.
Cleaning an implant-supported bridge includes flossing around each of the implants to remove dental plaque, a thin film of food particles and bacteria most responsible for dental disease. To perform this task, you'll have to pass the floss between the bridge and gums to access the sides of each implant.
To help make it easier, you can use a tool like a floss threader, a thin, shaft-like device with a loop on one end and a needle-like point on the other. You'll first thread about 18" of floss through the end and then pass the threader between the bridge and gums with the sharp end toward the tongue.
With the threader completely through, you'll then wrap the floss around your fingers as with regular flossing and move the floss up and down each side of the implants you can access. You'll then pull the floss out, reload the threader and move to the next section, repeating this process until you've flossed each side of each implant.
You can also use pre-cut floss with a stiffened end to thread between the bridge and gums or an interproximal brush with a thin bristled head that can reach underneath the bridge. And you might consider using an oral irrigator, a pump device that sprays a stream of pressurized water to remove and flush away plaque around implants.
To round out your hygiene efforts, be sure you visit your dentist at least twice a year for dental cleanings. Your dentist can also advise you and give you training on keeping your implants clear of disease-causing plaque. Cleaning around your implants will help ensure your restoration will last.

While many people still consider dental implants the "new kids on the block" in dental restoration, they're now in their fourth decade of use. And since their inception implant technology has continued to improve and revolutionize how we replace missing teeth.
Implants are a different "species" compared to other restoration methods. To be precise, an implant is a tooth root replacement—usually a titanium metal post imbedded directly into the jaw bone. Titanium is not only a biocompatible metal, but bone cells naturally grow on its surface to create a strong and durable hold. It's this secure hold that's most responsible for implants' high long-term success rate.
But we should also credit some of this success to the steady stream of advances over the years in implant construction and supporting technologies. For one thing, we're now more accurate and precise with implant placement thanks to advances in computer tomography (CT) and cone beam CT (CBCT) scanning.
These digital processes merge a series of images taken by a special camera to form a three-dimensional model of the jaw. We can manipulate this model on a computer monitor to view it from different vantage points. It can help us locate and avoid anatomical structures like nerves and sinuses when determining where to place a future implant. CT and CBCT are especially useful when there's a concern about adequate available bone, a necessity for stable implants.
Technology has also improved how we create surgical guides, often used during implant surgery to obtain the most accurate results. Surgical guides are custom-made devices that fit over the teeth with the drilling locations for the implants marked on them. Recent advances in 3-D printing have made these guides even more accurate so that they fit more securely in the mouth. This greater stability increases their accuracy during the drilling sequence during surgery.
These and other advances are helping ensure every implant is a success story. The end result is both a functional restoration and a beautiful smile.

While there’s usually a period of months between implant placement and the permanent crown, a new technique known as same-day tooth replacement installs both the implant and a temporary crown during the same visit. But be advised — it does have its risks and isn’t for everyone.
Successful same-day replacements require special attention during the three phases for implants: the removal (extraction) of the existing tooth; placement of the implant in the bone; and attachment of the crown, the visible tooth, to the implant. The tooth extraction lays the foundation for the entire process; the extraction procedure must be performed carefully to avoid undue damage to the socket. In addition, if infection or disease has compromised the site, an implant may not be possible immediately.
The implant must then be placed in the bone so that it’s stable and immovable. All implants stabilize with time as the bone grows and adheres to them, but we need greater stability for a same-day tooth replacement when an extraction is performed.
Our last consideration is positioning the implant so that the attached crown blends in naturally with the surrounding gum tissue and adjacent teeth. We must place it at the proper depth below the gum tissues so that the crown appears to emerge from them in the proper tooth length.
Taking extra care during all these phases, including the angle of crown attachment, will increase our chances of success. We still run a risk of implant damage or failure, however, from biting forces before the implant fully integrates with the bone. This means avoiding chewy foods and other situations that might increase the force on the implant. We may also use a temporary crown that’s slightly shorter than adjacent teeth so it won’t make full contact with the opposing tooth.
If you’d like to know if you’re a good candidate for a same-day tooth replacement, see us for a detailed examination. After reviewing your needs, we’ll be able to discuss with you the risks and benefits for a new look in one day.

So, you’ve just acquired an attractive restoration with dental implants. You may be thinking at least with these teeth you won’t have to worry about dental disease.
Think again. While the implants and their porcelain crowns are impervious to decay the surrounding gums and bone are still vulnerable to infection. In fact, you could be at risk for a specific type of periodontal (gum) disease called peri-implantitis (inflammation around the implant).
Bacterial plaque, the thin bio-film most responsible for gum disease, can build up on implant crowns just as it does on natural tooth surfaces. If it isn’t removed with daily brushing and flossing and regular dental cleanings the bacteria can trigger an infection in the gums.
Besides weakening gum tissues, gum disease can also cause bone loss, of critical importance to dental implants. An implant depends on the bone they’re inserted in to hold them in place. If the bone around an implant becomes infected it could begin to be lost or dissolve (resorb), which could lead to loss of the implant.
That’s why it’s critical to keep the natural tissue structures supporting your implants infection-free. Not only is daily hygiene a must, but your implants and any remaining natural teeth should undergo professional cleaning at least twice a year or more if your dentist recommends it.
Cleanings involving implants will also be a bit different from natural teeth. While the dental materials used in the crown and implant post are quite durable, regular cleaning instruments can scratch them. Although tiny, these scratches can become hiding places for bacteria and increase your risk of infection.
To avoid this, your hygienist will use instruments (known as scalers and curettes) usually made of plastics or resins rather than metal. The hygienist may still use metal instruments on your remaining natural teeth because their enamel can tolerate metal without becoming scratched creating a smoother surface.
While keeping implants clean can sometimes be a challenge, it’s not impossible. Implants on average have a long-term success rate above 95%. With both you and your dentist caring and maintaining these state-of-the-art restorations, you may be able to enjoy them for decades.
