Even in the 21st Century, losing most or all of your teeth is still an unfortunate possibility. Many in this circumstance turn to dentures, as their great-grandparents did, to restore their teeth. But today's dentures are much different from those of past generations—and dental implants are a big reason why.
The basic denture is made of a gum-colored, acrylic base with artificial teeth attached. The base is precisely made to fit snugly and comfortably on the patient's individual gum and jaw structure, as the bony ridges of the gums provide the overall support for the denture.
Implants improve on this through two possible approaches. A removable denture can be fitted with a metal frame that firmly connects with implants embedded in the jaw. Alternatively, a denture can be permanently attached to implants with screws. Each way has its pros and cons, but both have two decided advantages over traditional dentures.
First, because implants rather than the gums provide their main support, implant-denture hybrids are often more secure and comfortable than traditional dentures. As a result, patients may enjoy greater confidence while eating or speaking wearing an implant-based denture.
They may also improve bone health rather than diminish it like standard dentures. This is because the forces generated when chewing and eating travel from the teeth to the jawbone and stimulate new bone cell growth to replace older cells. We lose this stimulation when we lose teeth, leading to slower bone cell replacement and eventually less overall bone volume.
Traditional dentures not only don't restore this stimulation, they can also accelerate bone loss as they rub against the bony ridges of the gums. Implants, on the other hand, can help slow or stop bone loss. The titanium in the imbedded post attracts bone cells, which then grow and adhere to the implant surface. Over time, this can increase the amount of bone attachment and help stymie any further loss.
An implant-supported denture is more expensive than a standard denture, but far less than replacing each individual tooth with an implant. If you want the affordability of dentures with the added benefits of implants, this option may be worth your consideration.

For generations, dentures have helped people avoid the dire consequences of total teeth loss. Now, implant technology is making them even better.
Composed of life-like prosthetic teeth fixed within a plastic or resin gum-colored base, dentures are manufactured to fit an individual patient’s mouth for maximum fit, comfort and performance. But dentures also have a critical drawback—they can’t stop bone loss in the jaw.
Bone is constantly regenerating as older cells dissolve and then are replaced by newer cells. In the jawbone, the forces generated when we chew travel through the teeth to the bone and help stimulate this new cell growth. When teeth are missing, though, the bone doesn’t receive this stimulus and may not regenerate at a healthy rate, resulting in gradual bone loss.
Dentures can’t transmit this chewing stimulus to the bone. In fact, the pressure they produce as they rest on top of the gums may actually accelerate bone loss. Over time then, a denture’s once secure and comfortable fit becomes loose.
In the past, most patients with loose dentures have had them relined with new dental material to improve fit, or have new dentures created to conform to the changed contours of the jaws. But implant technology now offers another alternative.
Implants are in essence a tooth root replacement. Dentists surgically implant a titanium metal post directly into the jawbone that naturally attracts bone cells to grow and adhere to it over time (a process called osseointegration). This not only creates a secure and lasting hold, it can also stop or even reverse bone loss.
Most people know implants as single tooth replacements with a porcelain crown attached to the titanium post. But a few strategically placed implants can also support either removable or fixed dentures. Removable dentures (also called overdentures) usually need only 3 or 4 implants on the top jaw and 2 on the bottom jaw for support through built-in connectors in the dentures that attach to the implants. A fixed bridge may require 4-6 implants to which they are permanently attached.
There are pros and cons for each of these options and they’re both more expensive than traditional dentures. In the long run, though, implant-supported dentures could be more beneficial for your bone health and hold their fit longer.
While celebrating all that a new year brings, take a moment to remember the New Year's Day birthday of a true American patriot: the legendary Paul Revere. Ironically, he became a legend some 80 years after his midnight trek to warn colonists of approaching British troops, thanks to Henry Wadsworth Longfellow's 1861 poem “Paul Revere's Ride.” He was much better known to his fellow Bostonians as a prosperous silversmith, engraver—and “artificial teeth” maker.
That's right. Among his many business endeavors, Revere's résumé also included dental prosthetics, specifically custom dentures made of ivory. For the time, his work was state-of-the-art technology that far surpassed older tooth replacement methods.
But when we compare Revere's foray into the dental arts and today's restorations, his high quality 18th Century dentures were the proverbial “horse and buggy,” while modern denture technology seems like “supersonic transport.” Not only are today's dentures made of superior materials that are more “toothlike” in appearance, the means to create them using digital technology gives wearers a more secure and comfortable fit.
The modern denture—an appliance that replaces multiple or all lost teeth—is composed of a polymer base, usually acrylic that is colored to resemble gum tissue. Attached to this base are the prosthetic (“false”) teeth that replace those lost along the jaw. These new teeth are usually made of a durable dental material like porcelain that looks and functions like real teeth.
The basic design of today's denture hasn't changed much in the last century. What has changed is our ability to create dentures that follow an individual jaw contours much more precisely. Using the latest digital technology, we're able to obtain highly accurate impressions of the mouth to guide the manufacturing process. Fit is critically important for how dentures feel and function in the mouth. If they are too loose, they become uncomfortable and limit which foods you can eat.
If that weren't enough, recent advancements with dental implants have taken dentures to an entirely new level, beyond anything imaginable in Revere's day. We're now able to create dentures that connect or are permanently affixed to implants set within the jaw, which makes them more stable and secure. An implant-supported denture also helps prevent bone loss, a weakness of traditional dentures, causing them to loosen over time.
As amazing as they are, we wouldn't have the modern version of dentures without craftsmen like Paul Revere who helped advance the cause of dental restoration. So, lift a glass of holiday cheer this season to this hero of the American Revolution—and of American dentistry.
Since as many as 26 percent of older U.S. adults have lost all their teeth, there are a large number Americans who wear full removable dentures, also known as false teeth. You may be one of them.

Maybe you don’t like to be without teeth — ever. Or maybe you get a little forgetful sometimes. Whatever the reason, if you’re wearing your dentures to bed at night, we have one message for you: Please stop!
Sleeping in dentures can have serious health consequences. A recent study published in the Journal of Dental Research found that nursing home residents who wore their dentures to sleep were 2.3 times more likely to be hospitalized or even die of pneumonia as those who did not sleep in dentures. But how can wearing dentures at night more than double your chances of getting a lung infection?
As the study noted, pneumonia-causing bacteria can readily be moved from the mouth to the lungs simply by breathing. And dentures that are not removed at night can become breeding grounds for all kind of bacteria and fungi (such as yeast). That’s what makes them potentially dangerous.
Another condition often seen in people who wear upper dentures continually is called denture stomatitis, which is characterized by a red, inflamed palate (roof of the mouth) that has been infected with yeast. The yeast microorganisms can also infect cracked corners of the mouth, a condition known as angular cheilitis. Moreover, it has also been shown that people who sleep in dentures have higher blood levels of a protein called interleukin 6, which indicates that the body is fighting an infection. Need we go on?
Wearing dentures is supposed to improve your quality of life, not reduce it. So promote good health by taking your dentures out at night, and sticking to a good daily oral hygiene routine:
- Remove and rinse your dentures after every meal.
- Brush your dentures at least once a day with a soft toothbrush or denture brush and dish soap, liquid antibacterial soap, or denture cleanser (but don’t use toothpaste — it is too abrasive).
- Store your dentures in water or a solution made for this purpose.
- Brush your gums and tongue every day with a soft toothbrush (not the same one you clean your dentures with).
- Rinse your dentures in clean water before you put them back in your mouth.
