People have depended on dentures for generations—and they still do. That's because they work, both in restoring dental function and a smile marred by missing teeth.
But they have one major drawback related to bone health. That's because living bone has a life cycle: as older cells die, new ones form to take their place. The pressure generated when we chew stimulates this growth. But when this stimulus goes missing along with the teeth, the cell replacement rate slows and bone volume and density gradually diminishes.
Traditional dentures can't transmit this chewing pressure stimulus. And because they rest directly on the gum ridges, they can adversely affect the underlying bone and actually accelerate bone loss.
But implant technology potentially solves this bone loss problem with dentures by using implants rather than the gums to support them. It's a two-fold benefit: first, the implants relieve much of the irritation to the gums and bone caused by traditional dentures. Primarily, though, the implants themselves can slow or even stop continuing bone loss.
Most implants are made of titanium, not only because it's compatible with the body, but also because it has an affinity with bone. Over time bone cells grow on the titanium post imbedded in the jawbone. This process not only creates stability and durability, it can improve bone health.
In recent years dentists have incorporated implants with dentures to create two exciting treatment options. With one option, the dentist installs two or more implants in the jaw, to which a specially fitted removable denture can be attached. You would still have the ease of removing the denture for cleaning, while gaining greater stability and a reduced risk of bone loss.
The other option is a fixed denture (or bridge) attached permanently to implants. For this option, a patient's jawbone must be adequate and healthy enough to support at least four to six implants. A fixed denture is also often costlier and more complex than a removable denture, but it can feel more like real teeth. It also promotes better bone health too.
Although both options are more expensive than traditional dentures, they can pay dividends for long-term dental health. Implants could help you enjoy your new dentures and resulting smile for a long time to come.

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.

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.

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.

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.
