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.
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.

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.

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.
