People have depended on dentures for generations—and they still do. That's because they work, both in restoring dental function and a smile marred by missing teeth.
But they have one major drawback related to bone health. That's because living bone has a life cycle: as older cells die, new ones form to take their place. The pressure generated when we chew stimulates this growth. But when this stimulus goes missing along with the teeth, the cell replacement rate slows and bone volume and density gradually diminishes.
Traditional dentures can't transmit this chewing pressure stimulus. And because they rest directly on the gum ridges, they can adversely affect the underlying bone and actually accelerate bone loss.
But implant technology potentially solves this bone loss problem with dentures by using implants rather than the gums to support them. It's a two-fold benefit: first, the implants relieve much of the irritation to the gums and bone caused by traditional dentures. Primarily, though, the implants themselves can slow or even stop continuing bone loss.
Most implants are made of titanium, not only because it's compatible with the body, but also because it has an affinity with bone. Over time bone cells grow on the titanium post imbedded in the jawbone. This process not only creates stability and durability, it can improve bone health.
In recent years dentists have incorporated implants with dentures to create two exciting treatment options. With one option, the dentist installs two or more implants in the jaw, to which a specially fitted removable denture can be attached. You would still have the ease of removing the denture for cleaning, while gaining greater stability and a reduced risk of bone loss.
The other option is a fixed denture (or bridge) attached permanently to implants. For this option, a patient's jawbone must be adequate and healthy enough to support at least four to six implants. A fixed denture is also often costlier and more complex than a removable denture, but it can feel more like real teeth. It also promotes better bone health too.
Although both options are more expensive than traditional dentures, they can pay dividends for long-term dental health. Implants could help you enjoy your new dentures and resulting smile for a long time to come.

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 it's possible for a teenager to lose a tooth from decay, it's more common they'll lose one from an accidental knockout. If that happens to your teenager, there are some things you should know to achieve a good outcome.
Our top concern is to preserve the underlying bone following tooth loss. Like other tissues, bone has a life cycle: older cells dissolve and are absorbed by the body (resorption), then replaced by new cells. The biting pressure generated when we chew helps stimulate this growth. But bone around a missing tooth lacks this stimulation and may not keep up with resorption at a healthy rate.
This can cause a person to lose some of the bone around an empty tooth socket. To counteract this, we may place a bone graft at the site. Made of bone minerals, usually from a donor, the graft serves as a scaffold for new bone growth. By preventing significant bone loss we can better ensure success with a future restoration.
Because of its lifelikeness, functionality and durability, dental implants are considered the best of the restoration options that can be considered to replace a missing tooth. But placing an implant during the teen years is problematic because the jaws are still growing. If we place an implant prematurely it will appear to be out of alignment when the jaw fully matures. Better to wait until the jaw finishes development in early adulthood.
In the meantime, there are a couple of temporary options that work well for teens: a removable partial denture (RFP) or a fixed modified bridge. The latter is similar to bridges made for adults, but uses tabs of dental material that bond a prosthetic (false) tooth to the adjacent natural teeth to hold it in place. This alleviates the need to permanently alter the adjacent natural teeth and buy time so that the implant can be placed after growth and development has finished.
And no need to worry about postponing orthodontic treatment in the event of a tooth loss. In most cases we can go ahead with treatment, and may even be able to incorporate a prosthetic tooth into the braces or clear aligners.
It's always unfortunate to lose a tooth, especially from a sudden accident. The good news, though, is that with proper care and attention we can restore your teenager's smile.

The month of May has been designated “Better Speech & Hearing Month” by the American Speech-Language-Hearing Association. Why would this be of interest to dental professionals? Because teeth are vital for good speech, and missing teeth can make it very hard to speak properly.
Speech is all about sounds, and forming sounds correctly requires proper positioning of oral structures such as the lips, tongue and teeth. For example, there are some words that are almost impossible to pronounce correctly without touching your tongue to your teeth. In fact, one of the hardest words to say without teeth…is teeth!
Missing teeth can affect speech indirectly as well, by reducing self-confidence. People who are missing front teeth often develop the habit of talking behind their hand or mumbling to avoid revealing the gap in their smile. Not being able to speak clearly and confidently can affect not only your appearance, but also your job prospects and social life. So what can you do about missing teeth?
Dental implants are today’s preferred tooth-replacement method. Implants are small titanium posts that are inserted in the jaw bone beneath your gums. They serve as “roots” to hold realistic-looking prosthetic (artificial) teeth in place. Implants can be used to replace one tooth, a group of teeth, or an entire row of teeth (upper or lower). Sometimes a dental implant can be placed the same day a failing tooth is removed so that you won’t need a second surgical procedure.
The healthy natural teeth on either side of the gap can also be used to support one or more replacement teeth. This method, called bridgework, can be used to replace a single tooth or several teeth in a row. Another option is removable dentures, which do not stay in the mouth all the time.
Each of these options has its benefits and risks. We’d be happy to discuss all of them in detail and help you decide which would be best in your own situation.

Dental implants are considered today’s premier method for restoring missing teeth. Obtaining an implant, though, is often a long process and the implants themselves must be surgically placed within the jaw bone. Nothing to worry about, though: implant surgery is a minor to moderate procedure akin to a surgical tooth extraction.
Still like any surgery, this procedure does involve cutting into the soft tissues of the gums and could allow oral bacteria to enter the bloodstream. While most bacteria in the mouth are harmless (and even beneficial) a few strains can cause disease. For some people, especially those with certain heart conditions or joint replacements, this could potentially cause serious issues in other parts of their body that might be highly susceptible to infection.
To guard against this, it’s been a long-standing practice in dentistry to prescribe antibiotics to certain high risk patients before a procedure. Although this departs from the normal use of antibiotics for already occurring infections, due to the circumstances this has been deemed an acceptable measure to prevent disease.
In the past, the categories of patients for which preventive antibiotics were appropriate had been more extensive. In recent years, though, both the American Dental Association and the American Heart Association have adjusted their recommendations. Today, your dental provider may recommend antibiotic pre-treatment if you have a prosthetic (artificial) heart valve, a history of infective endocarditis (inflammation of the inner linings of the heart), a heart transplant or certain congenital heart conditions.
While physicians may still recommend premedication with antibiotics for patients with joint replacements, it’s not as blanket a standard as it might once have been. It’s now only recommended for certain cases, such as patients who’ve received a prosthetic joint within the last two years.
There’s still an ongoing debate about the effectiveness of antibiotic pre-medication. However, there’s evidence medicating before procedures with antibiotics can be beneficial in avoiding infection. If you fall into one of the categories just mentioned or are concerned about infection, feel free to discuss with your dentist if using antibiotics before your implant surgery is wise move for you.
