Although teeth are quite durable, we can still lose them—even all of them—to disease or injury. The good news, though, is that we have effective ways to restore teeth after they're lost. One of these, the removable denture, has given people their teeth back for several generations. And with recent advances in technology, today's dentures are even better.
Although more advanced, today's dentures share the same basic structure as those from a century ago: prosthetic (false) teeth set in a plastic resin colored to resemble the gums. The traditional denture is molded to fit snugly over an individual patient's alveolar jaw ridges, which once supported the former natural teeth. The denture stays in place primarily through a suction effect between the denture and the ridges.
Modern technology, though, has greatly improved today's dentures. Digital imaging can be used to generate highly accurate impressions of the dental ridges that can lead to denture bases with better fit. Dentists using photographs of the patient, especially in earlier years, are better able to identify facial landmarks, which enables them to position the new teeth to more closely recreate the patient's former smile.
These technological aids now help dentists to create more attractive dentures with better support and comfort. But the fit that makes this possible may not last due to a particular weakness inherent in traditional dentures—continuing bone loss. When teeth are missing, the underlying jawbone can lose bone volume over time. Dentures don't stop this process and can accelerate it due to constant friction and pressure on the dental ridges.
But a new modification incorporating dental implants with dentures can help solve these problems. By placing a few strategically positioned implants in the jawbone that then connect with the denture, the appliance not only gains more stability, but also produces less pressure on the dental ridges. In addition, bone cells naturally grow and adhere to the titanium implant posts, which helps to stop or slow bone loss.
If you've experienced total tooth loss, dentures are an affordable and effective option. Thanks to modern dental advances, you can get back the smile and dental function you once lost.

Dentures can be an effective and affordable solution for people who've lost all their teeth. With them a person can once again eat nutritiously, speak clearly and smile confidently — and with regular care they can last for years.
As part of that ongoing care, be sure you consider one important thing with your dentures: you may want to take them out at night while you sleep. If you do you'll lessen your chances of developing these 4 health problems.
Accelerated bone loss. Traditional dentures are fitted to rest securely on the gums. This, however, creates pressure on the gums and the bony ridges beneath them that can contribute to bone loss. Wearing dentures around the clock usually accelerates this process, which could eventually lead to among other problems looser denture fit and discomfort.
Bacterial and fungal growth. Microorganisms that cause oral diseases find conducive breeding spots on the underside of dentures while they're worn in the mouth. Studies have found that people who continuously wear their dentures are more likely to have bacterial plaque and oral yeast than those that don't.
Potentially dangerous infections. Bacterial and fungal growth increases your risk of oral infections that could affect more than your mouth. A recent study of elderly nursing home residents found those who wore their dentures during sleep were over twice as likely to develop serious cases of pneumonia requiring hospitalization. It's believed bacteria harbored on the dentures can pass from the mouth to the lungs as a person breathes over them while they sleep.
Blocked salivary flow. During the night our salivary flow naturally ebbs; wearing dentures while we sleep could cause denture stomatitis, in which the tissues covered by a denture (particularly along the roof of the mouth) become inflamed and infected with yeast. It's often accompanied by angular cheilitis or cracking at the corners of the mouth that becomes infected by the same yeast.
Wearing your dentures while you sleep contributes to conditions ranging from irritating to life-threatening. To prevent such problems clean your dentures as well as the rest of your mouth regularly — and talk to your dentist whether you should leave them out when you go to bed.

Some patients who wear dentures face a kind of Catch-22: their denture fit may have loosened and become uncomfortable over time due to continued bone loss, yet the same bone loss prevents them from obtaining dental implants, a superior tooth replacement system to dentures.
But there may be a solution to this dilemma that combines the stability of implants with a removable denture. A set of smaller diameter implants — “mini-implants” — can support a removable denture with less bone than required by a conventional implant.
Like all living tissue, bone has a life cycle: after a period of growth, the older bone dissolves and is absorbed by the body, a process known as resorption. The forces generated when we bite or chew are transmitted by the teeth to the jawbones, which stimulates new bone formation to replace the resorbed bone. When the teeth are lost, however, the stimulation is lost too; without it, resorption will eventually outpace bone growth and repair, causing the bone mass to shrink.
Removable dentures also can’t supply the missing stimulation — bone loss continues as if the dentures weren’t there; and due to the compressive forces of a denture, bone loss accelerates. As the jawbone structure used to originally form the denture’s fit eventually shrinks, the denture becomes loose and difficult to wear. It’s possible to adjust to the new jaw contours by relining the dentures with new material or creating a new set of dentures that match the current bone mass. Without adequate bone, fixed crowns or bridges anchored by conventional implants may also be out of the picture.
On the other hand, mini-implants with their smaller diameter need less bone than the traditional implant. A few strategically placed within the jaw are strong and stable enough to support a removable denture. One other advantage: these mini-implants can be installed in one visit with local anesthesia and usually without the need for incisions or stitches.
