Losing all your teeth can dramatically impact your life for the worst. Fortunately, we can give you your "teeth" back. The most common way, at least until a few decades ago, is with custom dentures, which reasonably restore life-like appearance and dental function. But it does have one major drawback—it can't stop bone loss.
Loss of bone in the jaws often occurs with missing teeth. Normally, the bone continuously generates newer cells to replace older ones that have died. Chewing stimulates this growth as the force generated travels up through the teeth to the bone. But when teeth go missing, new bone growth slows, eventually causing the bone's volume and density to decrease.
Dentures can't reactivate this lost stimulation, and so bone loss may continue. Dentures even accelerate this loss as the compressive forces applied to the bony ridge are detrimental. This often leads to a "loosening" of a denture's fit that can make them uncomfortable and less secure to wear.
Today, however, patients with total tooth loss have another option that could alleviate the problem of bone loss—dental implants. Since their inception forty years ago, implants have become the preferred method of both dentists and patients for tooth replacement.
Implants consist of a titanium metal post that's surgically imbedded into the jawbone. Bone cells are attracted to this particular metal, readily multiplying and adhering to the implant's titanium surface. Because of this, an implant can slow or even stop bone loss.
Most people are familiar with the single tooth implant with an attached lifelike crown. Although this use of implants could be used to restore total tooth loss, it can be quite costly replacing over two dozen teeth individually.
But implants could still be part of the answer for someone with complete tooth loss, because they can also be used to support traditional restorations. A few implants strategically placed around the jaw can support either a removable denture or a fixed bridge.
Besides being a cost-effective way to add support to these traditional tooth replacements, the inclusion of implants will likely decrease continuing bone loss. Most importantly, it can give you back your dental function—and your smile to boot.

A fair number of people with total tooth loss have arrived at this point after a long history of dental issues. It's quite likely they've had a series of bridges or partial dentures over the years to accommodate lost teeth at various times before moving to full dentures.
For many, it often seems easier to extract any remaining teeth at some point and simply move on to a total restoration. It's often better for oral health, however, to preserve any remaining teeth for as long as possible and update restorations as needed. Dental implants could make this type of staged restoration strategy much easier to manage.
Implants are tiny metal posts surgically imbedded in a patient's jawbone. Over time, bone cells grow and adhere to the implant's titanium surface, creating a strong and durable hold. Its most familiar application is as a replacement for an individual tooth.
But because of their strength and durability, this advanced dental technology is also used to support other restorations like bridges and partial or full dentures by way of a few strategically placed implants. And it's in that role that they can be useful in planning and implementing future restoration upgrades when needed.
Under this strategy, we add implants to supplement pre-existing implants from earlier restorations to support the updated dental work. For example, we might have previously placed an implant supporting a single tooth or a small bridge. When the need later arises for a partial denture, we can add additional implants to be used with the earlier one to support the new denture.
If the earlier implants have been well-placed, we need only to add enough implants necessary to support a full denture when the time comes. How many will depend on the particular type of denture: A removable lower denture may only require one additional implant with one already in place. A fixed upper or lower denture will require enough to bring the number to between four and eight.
Taking this long-term approach can be more cost-effective in the long-run. More importantly, it can make for a smoother path for the patient and help preserve remaining teeth for as long as possible.

Placing a dental implant within the jawbone requires a surgical procedure. For most people it’s a relatively minor affair, but for some with certain health conditions it might be otherwise. Because of their condition they might have an increased risk for a bacterial infection afterward that could interfere with the implant’s integration with the bone and lead to possible failure.
To lower this risk, dentists for many years have routinely prescribed an antibiotic for patients considered at high-risk for infection to take before their implant surgery. But there’s been a lively debate among health practitioners about the true necessity for this practice and whether it’s worth the possible side effects that can accompany taking antibiotics.
While the practice still continues, current guidelines now recommend it for fewer health conditions. The American Dental Association (ADA) together with the American Heart Association (AHA) now recommend antibiotics only for surgical patients who have prosthetic heart valves, a history of infective endocarditis, a heart transplant or certain congenital heart conditions.
But patients with prosthetic joint replacements, who were once included in the recommendation for pre-surgical antibiotics, are no longer in that category. Even so, some orthopedic surgeons continue to recommend it for their joint replacement patients out of concern that a post-surgical infection could adversely affect their replaced joints.
But while these areas of disagreement about pre-surgical antibiotics still continue, a consensus may be emerging about a possible “sweet spot” in administering the therapy. Evidence from recent studies indicates just a small dose of antibiotics administered an hour before surgery may be sufficient to reduce the risk of infection-related implant failure with only minimal risk of side effects from the drug.
Because pre-surgical antibiotic therapy can be a complicated matter, it’s best that you discuss with both the physician caring for your health condition and your dentist about whether you should undergo this option to reduce the infection risk with your own implant surgery. Still, if all the factors surrounding your health indicate it, this antibiotic therapy might help you avoid losing an implant to infection.

If you have a problem tooth we’ve recommended removing, those “Tooth in one day” ads—a tooth removed and an implant placed at the same time—might start to pique your interest. But there are a few factors we must consider first to determine if this procedure is right for you. Depending on your mouth’s health conditions, you may need to wait a little while between tooth extraction and implantation.
Here are 3 timing scenarios for receiving your implant after tooth removal, depending on your oral health.
Immediately. The “tooth in one day” scenario can be much to your liking, but it could also be tricky in achieving the best results. For one, the implant may fit too loosely—the bone around the socket might first need to heal and fill in or undergo grafting to stimulate regeneration. In other words, immediate implant placement usually requires enough supporting bone and an intact socket. Bone grafting around the implant is usually needed as well.
After gum healing. Sufficient gum coverage is also necessary for a successful outcome even if the bone appears adequate. To guard against gum shrinkage that could unattractively expose too much of the implant, we may need to delay implant placement for about 4 to 8 weeks to allow sufficient gum healing and sealing of the extraction wound. Allowing the gums to heal can help ensure there’s enough gum tissue to cover and protect the implant once it’s placed.
After bone healing. As we’ve implied, implants need an adequate amount of supporting bone for best results. When there isn’t enough, we might place a bone graft (often immediately after tooth extraction) that will serve as a scaffold for new bone to grow upon. Depending on the degree of bone loss, we may wait until some of the bone has regenerated (about 2 to 4 months) and then allow the natural process of bone cells growing and adhering to the implant (osseointegration) to complete the needed bone growth. If bone loss is extensive, we may need to wait until full healing in 4 to 6 months to encourage the most stable outcome.

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.
