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.

Perhaps you’ve heard the old saying: “Take care of your dentures and your dentures will take care of you.” Well, maybe it’s not that old—but it’s still a sensible notion. Maintaining your dentures by routinely cleaning them and having them checked for fit will improve their longevity.
There’s one other thing you should include on your maintenance routine—avoid wearing your dentures 24/7, especially while you sleep. This bad habit could lead to some unpleasant consequences.
For one, wearing dentures continuously can accelerate bone loss in the jaw that eventually causes your dentures to lose their comfortable fit. Bone loss is a natural consequence of tooth loss because the bone no longer receives the stimulation to grow transmitted by the teeth during chewing. Dentures can’t transmit this stimulus; what’s more, the pressure they place on the gums and underlying bony ridges could make bone loss worse. You can relieve this gum pressure at night by taking them out.
Dentures can also become a breeding ground for bacteria and fungi that cause disease, irritation and unpleasant mouth odors. Taking dentures out at night deprives these microorganisms of a prime opportunity to carry on business as usual—and it’s also a great time to clean your dentures. People who sleep with their dentures in their mouth are more likely to have gum or oral yeast infections and higher levels of proteins produced by white cells that increase inflammation. That could contribute to other diseases throughout the body.
Besides taking your dentures out at night, you should also practice other daily hygiene tasks. Remove your dentures after eating and rinse them with clean water. Brush your dentures daily with a soft-bristled brush and dish or antibacterial soap or dental cleanser (no toothpaste—it’s too abrasive for denture surfaces). Be sure you clean your gums and tongue every day too. When your dentures are out, store them in clean water or preferably an alkaline peroxide-based solution.
Removing your dentures at night and these other good habits will help extend the life and fit of your dentures. It could also help keep the rest of you healthy.

Generations have depended on dentures to effectively and affordably replace lost teeth. But they do have a major weakness: They contribute to jawbone loss that creates not only mouth and facial problems, but can also ruin a denture’s fit.
Bone loss is a normal consequence of losing teeth. The biting forces normally generated when we chew stimulate new bone to replace older bone. When a tooth is missing, however, so is that chewing stimulation. This can slow bone replacement growth and gradually decrease the density and volume of affected bone.
While dentures can restore dental appearance and function, they can’t restore this growth stimulation. What’s worse, the pressure of the dentures against the gum-covered jaw ridge they rest upon may irritate the underlying bone and accelerate loss.
But there is a solution to the problem of denture-related bone loss: an implant-supported denture. Rather than obtaining its major support from the gum ridges, this new type of denture is secured by strategically-placed implants that connect with it.
Besides the enhanced support they can provide to a denture restoration, implants can also deter bone loss. This is because of the special affinity bone cells have with an implant’s imbedded titanium post. The gradual growth of bone on and around the implant surface not only boosts the implant’s strength and durability, it can also improve bone health.
There are two types of implant-supported dentures. One is a removable appliance that connects with implants installed in the jaw (three or more for the upper jaw or as few as two in the lower). It may also be possible to retrofit existing dentures to connect with implants.
The other type is a fixed appliance a dentist permanently installs by screwing it into anywhere from four and six implants. The fixed implant-supported denture is closer to the feel of real teeth (you’ll brush and floss normally), but it’s usually more costly than the removable implant-supported denture.
While more expensive than traditional ones, implant-supported dentures still cost less than other restorations like individual implant tooth replacements. They may also help deter bone loss, which may lead to a longer lasting fit with the dentures. Visit your dentist for an evaluation of your dental condition to see if you’re a good candidate for this advanced form of dental restoration.

Dentures, removable restorations for missing teeth and gum tissue, can take a number of different forms, but are usually of two different types: complete and partial. A complete denture replaces all the teeth in a given arch. A removable partial denture (RPD), on the other hand, replaces several missing teeth while using the remaining teeth as support.
A common type of RPD formed of plastic is known as a “flipper” because it’s lightweight enough to be “flipped out” or moved around with the tongue. They serve an important purpose as a temporary appliance for use between periodontal treatment, implant placement and similar treatments before obtaining a more permanent restoration. In fact, they’re often referred to as “transitional” RPDs because they’re not designed for permanent tooth replacement.
Because of their low cost relative to other restorations, however, they often become the permanent choice for many people. While a well-constructed, properly fitting RPD in a healthy mouth can be an affordable alternative for people on modest budgets, their long-term use may increase the risk of dental disease and accelerated bone loss. Decades of research verify that people who permanently wear RPDs encounter more tooth decay and periodontal (gum) disease than non-wearers.
This is because the attachment points of a plastic RPD to remaining teeth increases bacterial growth, which can cause both tooth decay and gum disease. This doesn’t only endanger the survival of the remaining teeth, it can lead to bone loss that will affect the RPD’s fit.
While the better course is to consider RPDs as a stepping stone to dental implants or a fixed bridge, there’s an intermediary RPD constructed of cast vitallium or gold alloy that could be considered a permanent choice. These are even lighter weight than plastic and less obtrusive in their attachments in the mouth, which can reduce plaque stagnation and promote a better oral environment.
Regardless of your choice in dentures, it’s always important to maintain good consistent oral hygiene with daily brushing and flossing and semi-annual professional cleanings and checkups. Keeping a healthy mouth will help reduce your risk of dental disease and increase your satisfaction with your denture of choice.
