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.
For people with edentulism (total loss of teeth), removable dentures is a viable option for regaining both lost function and an attractive appearance. From the moment they begin wearing them, denture wearers can chew food, speak and smile with confidence.
But there are downsides to dentures, especially if they’re not cared for properly. Dentures put pressure on the gums and bony ridges of the jaw, which can cause bone to dissolve (resorb) and decrease its volume over time. Without proper maintenance they can also become a breeding ground for bacteria and fungi that not only lead to bad breath but, in cases of partial dentures, can increase the risk of dental disease. They could also contribute to serious systemic diseases.
You can reduce some of these risks by following these 3 important denture maintenance tips. Doing so will help extend the life of your dentures, as well as keep your mouth healthy.
Clean your dentures at least once a day. In addition to taking your dentures out and rinsing them with water after eating, you should also brush them daily with dish detergent, antibacterial soap or denture cleaner — but not toothpaste, which is too abrasive. Effervescent (fizzing) cleaning tablets also aren’t a viable substitute for manual brushing in removing disease-causing plaque from denture surfaces.
Take your dentures out at night while you sleep. Wearing dentures 24/7 can hasten bone loss, as well as increase your chances of dental disease or even more serious illnesses. A recent study, for example, found nursing home patients who left their dentures in at night were twice as likely to experience serious complications from pneumonia as those who didn’t. While you sleep, store your dentures in water or in a solution of alkaline peroxide made for this purpose.
Brush your gums and tongue every day. Keeping your gum surfaces clean will help reduce the levels of bacteria and other microbes that can cause disease. You can either use an extra-soft tooth brush (not the one you use to clean your dentures) or a damp washcloth.
