Even with modern prevention and treatment advances, losing teeth in later life is still a sad but common part of human experience. Just as generations have before, many today rely on dentures to regain their lost dental function and smile.
But although effective, dentures have their weaknesses. The most serious: they can't prevent jawbone deterioration, a common problem associated with tooth loss.
Bone health depends on chewing forces applied to the teeth to stimulate replacement growth for older bone cells. When teeth are gone, so is this stimulation. Dentures can't replicate the stimulus and may even accelerate bone loss because they can irritate the bone under the gums as they rest upon them for support.
But there's a recent advance in denture technology that may help slow or even stop potential bone loss. The advance incorporates implants with dentures to create two hybrid alternatives that may be more secure and healthier for the supporting bone.
The first is known as an overdenture, a removable appliance similar to a traditional denture. But instead of deriving its support from the gums alone, the overdenture attaches to three to four implants (or only two, if on the lower jaw) that have been permanently set into the jawbone. This not only increases stability, but the implants made of bone-friendly titanium attract and foster increased bone growth around them. This can help slow or even stop the cycle of bone loss with missing teeth.
The second type is a fixed denture. In this version, four to six implants are implanted around the jaw arch. The denture is then secured in place to these implants with screws. It's a little more secure than the overdenture, but it's also more expensive and requires good quality bone at the implant sites.
If you've already experienced significant bone loss you may first need bone grafting to build up the implant sites for these options, or choose traditional dentures instead. But if you're a good candidate for an implant-supported denture, you may find it provides better support and less risk of continuing bone loss than traditional dentures.

Although dental disease prevention has made great strides over the last century, tooth decay and periodontal (gum) disease continue to pose a major health threat. People who’ve lost all of their teeth (edentulism) or most of them suffer the most with adverse effects on their overall health, function and appearance.
Removable dentures have been the traditional and most affordable means to treat edentulism. But even with material and construction advances in recent years, dentures can still lose their fit over time as the bone in the jaw shrinks. This happens because the bone no longer has the stimulus of natural teeth and older cells can’t be replenished at a healthy rate; the continuing compression of traditional dentures on the jaw’s bony ridges compounds the problem.
As the bone shrinks the dentures become loose and uncomfortable to wear. Among other results, this poor fit can drastically affect how you eat: studies of denture wearers have found a decrease in their diet’s nutritional value because they’re eating fewer vegetables or fibrous, “chewy” foods and more foods with refined carbohydrates and fats that are easier to eat but less nutritious.
There is an alternative, though, that might slow bone loss and provide a better long-term fit: an overdenture supported by dental implants. With this appliance, a few implants are strategically installed in the upper or lower jaw. Matched attachments securely fasten the denture to the implants. In this case, the implants not the jaw ridge and gums support the denture thereby preserving the bone.
If you’re healthy enough to undergo a tooth extraction, you should be able to handle implant surgery, a minor procedure usually performed with local anesthesia and with little to no discomfort afterward. It may even be possible to retrofit your current denture to work with the implants, but that will need to be determined during the planning stages.
Although more expensive than a traditional denture, overdentures are much more affordable than fixed restorations stabilized with implants. The difference, though, is the increase in your quality of life — for better nutrition, physical health and social confidence.
