It’s a common problem for denture wearers: after years of a comfortable fit, your dentures now seem to be uncomfortably loose. The reason, though, may have more to do with bone loss than the dentures.
Bone is a living tissue with a life cycle — it forms, it ages, and it eventually dies and dissolves (resorbs). It’s replaced with new bone and the cycle repeats. Additionally, the forces generated when we bite or chew are transmitted from the teeth to the jaw, which helps stimulate new bone growth. When the natural teeth are missing, however, the bone no longer receives this stimulus. Resorbed bone isn’t replaced at a healthy rate, which leads over time to bone loss.
Denture construction can also contribute to bone loss. The denture palate rests for support on the bony ridges that once held the teeth. Over time the compressive forces of the dentures apply damages and reduces the volume of gum tissue and eventually does the same to the bone. Combining all these factors, the reduced gum and bone volume will eventually alter the denture fit.
There are a few alternatives for correcting loose dentures. One is to reline them with new plastic, as either a temporary fix performed during an office visit or a more permanent relining that requires sending your dentures to a dental lab. Depending on the rate of bone loss, a patient could go through several denture relinings to accommodate ongoing changes in the jaw. At some point, though, it may be necessary to create a new set of dentures.
A third alternative that’s becoming increasingly useful is to incorporate dental implants into the denture design. Implants can of course be used to replace individual teeth, but a few strategically placed implants (usually of smaller dimension) can serve as a support platform for a removable denture. This relieves some of the compression force of a traditionally worn denture and can slow bone loss.

For centuries, people who've lost all their teeth have worn dentures. Although materials in today's dentures are more durable and attractive than those in past generations, the basic design remains the same — prosthetic (false) teeth set in a plastic or resin base made to resemble gum tissue.
If you're thinking of obtaining dentures, don't let their simplicity deceive you:Â a successful outcome depends on a high degree of planning and attention to detail customized to your mouth.
Our first step is to determine the best positioning for the prosthetic teeth. It's not an “eyeball” guess — we make a number of calculations based on the shape and size of your jaws and facial features to determine the best settings within the resin base. These calculations help us answer a few important questions for determining design: how large should the teeth be? How far forward or back from the lip? How much space between the upper and lower teeth when the jaws are at rest?
We also can't forget about the artificial gums created by the base. How much your gums show when you smile depends a lot on how much your upper lip rises. We must adjust the base size to accommodate your upper lip rise so that the most attractive amount of gum shows when you smile. We also want to match as close as possible the color and texture of your natural gum tissues.
There's one other important aspect to manage: how your upper and lower dentures function together when you eat or speak. This means we must also factor your bite into the overall denture design. This may even continue after your dentures arrive: we may still need to adjust them while in your mouth to improve function and comfort.
Ill-fitting, dysfunctional and unattractive dentures can be distressing and embarrassing. But with careful planning and customization, we can help ensure your new dentures are attractive and comfortable to wear now and for years to come.

People who’ve lost all their teeth have benefitted from a solution that’s been around for generations: removable dentures. These appliances have helped millions of people chew and eat food, speak, and smile confidently.
But for all their benefits (including affordability) there’s still some things you need to do to get the most out of them like cleaning them daily or having us check them regularly for damage and wear. And, there’s one thing you shouldn’t do: wear them around the clock. Not removing them when you sleep at night can harm your oral health and reduce your dentures’ longevity.
Dentures are fitted to rest on the gums and the bony ridges that once held your natural teeth. This exerts pressure on the underlying bone that can cause it to gradually dissolve (resorb). This loss in bone volume eventually loosens your denture’s fit. If you’re wearing them all the time, the process progresses faster than if you took them out each night.
The under surfaces of dentures are also a prime breeding ground for bacteria and fungi. Besides unpleasant odors and irritation, these microorganisms are also the primary cause for dental disease. Research has found that people who sleep in their dentures have higher occurrences of plaque, a thin film of bacteria and food remnants that cause periodontal (gum) disease. They’re also more prone to higher levels of yeast and the protein interleukin-6 in the blood, which can trigger inflammation elsewhere in the body.
To avoid these and other unpleasant outcomes, you should develop a few important habits: remove and rinse your dentures after eating; brush them at least once a day with dish or anti-bacterial soap or a denture cleanser (not toothpaste, which can be too abrasive); and take them out when you sleep and place them in water or an alkaline peroxide-based solution.
Be sure you also brush your gums and tongue with an extra soft toothbrush (not your denture brush) or wipe them with a clean, damp washcloth. This will help reduce the level of bacteria in the mouth.
Taking these steps, especially removing dentures while you sleep, will greatly enhance your well-being. Your dentures will last longer and your mouth will be healthier.
Maybe you don’t like to be without teeth — ever. Or maybe you get a little forgetful sometimes. Whatever the reason, if you’re wearing your dentures to bed at night, we have one message for you: Please stop!
Sleeping in dentures can have serious health consequences. A recent study published in the Journal of Dental Research found that nursing home residents who wore their dentures to sleep were 2.3 times more likely to be hospitalized or even die of pneumonia as those who did not sleep in dentures. But how can wearing dentures at night more than double your chances of getting a lung infection?
As the study noted, pneumonia-causing bacteria can readily be moved from the mouth to the lungs simply by breathing. And dentures that are not removed at night can become breeding grounds for all kind of bacteria and fungi (such as yeast). That’s what makes them potentially dangerous.
Another condition often seen in people who wear upper dentures continually is called denture stomatitis, which is characterized by a red, inflamed palate (roof of the mouth) that has been infected with yeast. The yeast microorganisms can also infect cracked corners of the mouth, a condition known as angular cheilitis. Moreover, it has also been shown that people who sleep in dentures have higher blood levels of a protein called interleukin 6, which indicates that the body is fighting an infection. Need we go on?
Wearing dentures is supposed to improve your quality of life, not reduce it. So promote good health by taking your dentures out at night, and sticking to a good daily oral hygiene routine:
- Remove and rinse your dentures after every meal.
- Brush your dentures at least once a day with a soft toothbrush or denture brush and dish soap, liquid antibacterial soap, or denture cleanser (but don’t use toothpaste — it is too abrasive).
- Store your dentures in water or a solution made for this purpose.
- Brush your gums and tongue every day with a soft toothbrush (not the same one you clean your dentures with).
- Rinse your dentures in clean water before you put them back in your mouth.
People who’ve lost all their teeth (a condition known as edentulism) face a decision on how to restore their lost function and appearance. And there are a number of options to consider.
A fixed bridge supported by dental implants, for example, is a good choice for patients who still have sufficient bone structure in their jaw. It’s not a good choice, however, for those with the opposite situation — who’ve experienced significant bone loss which has also affected their facial structure. For them, there’s a better alternative that also uses implants for support — the overdenture.
An overdenture is similar to a traditional denture, in that it’s made of life-like crowns permanently set in denture plastic, and may either partially or fully cover the roof of the mouth. The main difference, though, is that unlike traditional dentures which rest for support on the gum ridges, an overdenture is supported by strategically placed implants that the denture fits over and connects to — hence the name “overdenture.”
There are a number of advantages for an overdenture, especially for patients with bone loss. A removable, implant-supported denture can be designed to replace lost tissues that have altered facial appearance — to “fill in” the face and restore aesthetic harmony. Patients who’ve previously worn dentures will also often find their speech better improved than with fixed bridgework.
Because it’s removable, an overdenture and the underlying gums are easier to clean, which helps inhibit disease and lessen further bone loss. It also allows you to properly care for the denture, which can extend its longevity and reduce future potential maintenance and replacement costs.
If you would like to consider removable overdentures as an option, you should begin first with a thorough oral exam that includes evaluating the status of your bone, jaw and facial structure. From there we can advise you if overdentures are the best choice for you.
