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.

Twenty-six percent of American adults between 65 and 74 have lost all their teeth to dental disease. This isn’t an appearance problem only—lack of teeth can also harm nutrition and physical well-being.
Fortunately, we have advanced restorative options that can effectively replace missing teeth. Of these, there’s a tried and true one that’s both affordable and effective: removable dentures.
Dentures are simple in design: a plastic or resin base, colored with a pinkish-red hue to resemble gums to which we attach prosthetic (false) teeth. But while the design concept isn’t complicated, the process for creating and fitting them can be quite involved: they must conform to an individual patient’s jaws and facial structure if they’re going to appear natural.
If you’re considering dentures, here’s some of what it will take to achieve a successful outcome.
Positioning the teeth. The position of the prosthetic teeth on the base greatly determines how natural they’ll appear and how well they’ll function. So, we’ll need to plan tooth placement beforehand based on your facial and jaw structures, as well as photos taken of you before tooth loss. We’ll also consider how large the teeth should be, how far to place them forward or back from the lips, and whether to include “imperfections” from your old look that you see as part of your appearance.
Simulating the gums. While the teeth are your smile’s stars, the gums are the supporting cast. It’s important that we create a denture base that attractively frames the teeth by determining how much of the gums show when you smile, or adding color and even textures to better resemble gum tissue. We can also add ridges behind the upper teeth to support speech.
Balancing the bite. Upper and lower dentures don’t operate in and of themselves—they must work cooperatively and efficiently with each other during eating or speaking. So while appearance matters, the bite’s bite adjustment or balance might matter more. That’s why we place a lot of attention into balancing and adjusting the bite after you receive your dentures to make sure you’re comfortable.
This is a detailed process that we may need to revisit from time to time to make sure your dentures’ fit remains tight and comfortable. Even so, modern advances in this traditional restoration continue to make them a solid choice for total tooth loss.

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.
