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.

For most people, raising kids is an expensive proposition. (A recent estimate by the U.S. Department of Agriculture puts the average tab at almost a quarter of a million dollars before they turn 18.) But if you’ve been keeping up with parenting news lately, you may have come across an even more jaw-dropping fact: According to a survey by the Sunstar group, a maker of oral hygiene products, when the tooth fairy makes a pickup in New York City, she (or her parental surrogate) leaves an average of $13.25 per tooth!
That compares to $9.69 per tooth in Los Angeles, $5.85 in Chicago and $5.02 in Boston — and it’s a far higher rate than most other polls have shown. But it brings up a good question: What's a baby tooth really worth? Ask a dentist, and you may get an answer that surprises you: A lot more than that!
A child’s primary (baby) teeth usually begin coming in around the age of 6 to 9 months, and start making their exits about the time a child reaches six years; by the age of 10 – 13, they’re usually all gone. But even though they will not last forever, baby teeth are far from disposable — and they deserve the same conscientious care as adult teeth. Here’s why:
Primary teeth play the same important roles in kids’ mouths as permanent teeth do in the mouths of adults: they allow kids to bite and chew effectively, speak normally and smile brightly. Their proper functioning allows children to get good nutrition and develop positive social interactions as they grow toward adolescence — and those are things it’s difficult to put a price tag on.
But that’s not all baby teeth are good for. Each one of those little pearly-whites serves as a guide for the permanent tooth that will succeed it: It holds a space open in the jaw and doesn’t let go until the grown-up tooth is ready to erupt (emerge) from beneath the gums. If primary teeth are lost too soon, due to disease, decay or accidents, bite problems (malocclusions) can develop.
A malocclusion (“mal” – bad; “occlusion” – bite) can result when permanent teeth don’t erupt in their proper locations. “Crowding” is a common type of malocclusion that can occur when baby teeth have been lost prematurely. The new, permanent teeth may come in too close together because neighboring teeth have shifted into the gap left by the prematurely lost tooth, creating an obstruction for the incoming teeth. In other cases, the permanent teeth may emerge in rotated or misplaced positions.
Bite problems make teeth harder to clean and thus more prone to disease; they may also cause embarrassment and social difficulties. The good news is that it’s generally possible to fix malocclusion: orthodontists do it every day. The bad news: It will almost certainly cost more than $13.25 per tooth. Alternatively, baby teeth in danger of being lost too soon can often be saved via root canal treatment or other procedures.
We’re not advocating giving big money to toddlers — but we do want to make a point: The tooth fairy’s payout: a few dollars. A lifetime of good checkups and bright smiles: incalculable.
Semi-annual office cleanings are important for keeping teeth healthy and disease-free. If you’ve replaced some of your teeth with dental implants, though, you may be thinking they don’t need as much attention from your hygienist.
It’s quite the opposite — cleaning around implants is important, and actually requires additional attention. The reason for this relates to both how dental implants attach to the jaw and their constructive materials.
Natural teeth are held in place by the periodontal ligament with tiny fibers that attach to the teeth on one side of it and to the jawbone on the other. The ligaments and the gingival (gum) fibers (which are also attached to the tooth) provide some disease resistance to the teeth through its rich blood vessel and collagen network. Dental implants, on the other hand, anchor directly into the jawbone. The titanium integrates with the bone, which naturally attracts to the metal and grows around it, which provides the implant’s eventual attachment strength. The implant doesn’t attach to the gum tissue and won’t develop the same relationship with the periodontal ligament as natural teeth.
Bacterial plaque, the primary cause for tooth decay and periodontal (gum) disease, can collect on an implant crown just as readily as on a natural tooth. Although the materials that make up an implant can’t be affected by a plaque-induced infection, the gum tissues and supporting bone around it can. In fact, because implants lack the disease resistance of the gingival fibers and the ligament attachment, an infection can turn rapidly into a condition known as peri-implantitis that could cause bone and tissue loss and lead to the loss of the implant.
Your hygienist understands the importance of removing plaque and calculus (hardened plaque deposits) from around your dental implant. This often calls for different instruments made of plastics or resins that won’t scratch the implant’s highly polished surface. Scratches provide a haven for bacteria to collect and make it more difficult to dislodge them. Likewise, if the hygienist uses ultrasonic equipment that loosens plaque through vibration, the hygienist will often use nylon or plastic tips to minimize damage to the implant.
And don’t forget your own personal hygiene habits — they’re just as important with dental implants as with natural teeth. Keeping plaque under control, both at home and with your dentist, is crucial to longevity for your dental implants.
