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.

Although dental implants are best known as single tooth replacements, they can actually play a role in multiple or complete tooth loss (edentulism) restorations. While replacing multiple teeth with individual implants is quite expensive, there’s another way to incorporate them in a restoration at much less cost — as supports for bridges.
In this case, only a few strategically placed implants are needed to support restorations of multiple crowns fused together into a single unit. Implant-based bridges consist of two main types: the first type is a fixed bridge, which is permanently attached to the implants and can’t be removed by the patient. It’s often the preferred treatment for patients who’ve lost most or all of their teeth but have not yet experienced significant bone loss in the jaw.
This choice, however, may not be the best option for patients with significant bone loss. In these cases, there’s a second type of fixed bridge: an implant-supported fixed denture. This type of fixed denture provides support for the lost bone support of the lips and cheeks. If a fixed bridge is not possible due to finances or inadequate bone support to place 4 to 6 implants, a removable denture (also known as an overdenture) that’s supported and held in place by implants is the next best alternative. Unlike a fixed bridge, an overdenture can be removed by the patient for cleaning purposes, and will require less investment than a fixed bridge.
For people with bone loss, the overdenture does more than restore chewing and speech function. Because bone loss can diminish support of the facial structures — actually shorten the distance between the chin and the tip of the nose — an overdenture provides additional bulk to support these structures to improve appearance. Depending on what the patient needs for facial support, overdentures for the upper jaw can be designed as “full palates,” meaning the denture plastic completely covers the upper jaw palate, or open in which the plastic doesn’t completely cover the palate.
Besides the condition of your teeth, gums and bone, your own personal preferences and financial ability will also play a role in which option is best for you. After considering all these factors, we can recommend which of these types of implant-based restorations will fit your needs. With either bridge, fixed or removable, you’ll certainly benefit from the improvement to both your mouth function and your smile.

Think dental implants only replace individual teeth? Think again—this premier technology can also support other kinds of restorations to provide better stability and comfort. And, they also help improve bone health when incorporated with any type of tooth replacement options, especially dentures.
Although traditional dentures have enjoyed a long, successful history as a tooth replacement solution, they can interfere with bone health. That’s because regular dentures fit in the mouth by resting on the bony ridges of the jaw, which has implications for the bone.
As living tissue, bone goes through a growth cycle with older bone cells dying and dissolving and newer cells forming to take their place. The teeth play a role in this growth cycle — the forces generated when we chew travel up through the teeth and help stimulate bone growth. When teeth go missing, however, so does this stimulus.
Traditional dentures can’t replace this missing stimulus. In fact, the constant pressure of dentures on the jaw may even accelerate bone loss. A sign this is happening occurs when the dentures’ once tight fit begins to loosen and they become uncomfortable to wear.
Implant-supported dentures can help eliminate this problem. We first surgically place a few implants in the jaw, the number determined by which jaw (the lower requires less) and whether the denture is removable or fixed. If removable, the denture has connective points that match the implant locations — you simply connect them with the implants. If fixed, the denture is screwed into the implants to hold it in place.
So, how does this help bone health? For one, the denture no longer puts as much pressure on the jaw ridges—the main support comes from the implants. And, the implants themselves encourage bone stimulation: The titanium in the implant has a special affinity with bone cells that naturally grow and adhere to its metal surface. This natural integration between implant and bone can stop bone loss and may even help reverse it.
If you’re interested in implant-supported dentures, you’ll first need to undergo a full dental exam with your dentist. These restorations aren’t appropriate for all dental situations. But, if they can work for you, you may be able to enjoy the benefits of an implant-supported restoration.

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.

If you're considering dental implants to replace one or more missing teeth, you'll need to undergo a minor to moderate surgical procedure (depending on the number of implants) to install them. Depending on your current health status and medical history, you may need antibiotics before or after the procedure to help ensure a successful outcome.
Although implants have a high success rate (over 95%), they can still fail — and bacterial infection is a major culprit. Installing implants requires surgically accessing the bone through the gum tissues; you may also need other invasive procedures like tooth extraction or bone or gum tissue grafting. These disruptions to the soft tissues can introduce bacteria into the bloodstream.
In certain individuals, this can increase infection risk not only around the implant but also in other parts of the body. You may be at higher risk, for example, if you have serious health problems like cardiovascular disease or diabetes, a weakened immune system, you use tobacco or you're over or under normal weight. The American Dental and American Heart Associations both recommend antibiotics before dental implant surgery as a preventive measure against infection if you have a prosthetic heart valve, a history of infective endocarditis, a heart transplant or some congenital heart conditions.
For other patients with low to moderate risk for infection, there's vigorous debate on administering antibiotics before implant surgery. There are some side effects to antibiotic use, ranging from diarrhea to allergic reactions, and an increased concern in general to the developing resistance of many infectious agents due to the prevalent use of antibiotics. Many dentists and physicians are becoming more discriminate in the patients for which they prescribe antibiotics before surgical procedures.
It really comes down, then, to your particular case: not only the specific procedures you need but also your general health. After weighing these factors against the possible benefits for protecting your health and improving your odds of a successful outcome, we'll recommend whether antibiotic treatment for implants is right for you.
