Your dentures have served you well over the years. Lately, though, you’ve noticed the fit loosening in the lower denture. It’s not a new problem: you’ve had them refitted a few times already. But now it seems to be growing worse and you’re having more trouble chewing food or speaking clearly.
The problem isn’t all wear and tear with your dentures — the bone in your jaw is shrinking. A denture applies forces that are compressive. Natural teeth produce forces when we chew that travel through the tooth root and stimulate the bone to grow. Without teeth, there’s no such force to stimulate the bone. As a result, new bone cells don’t replace older cells at a healthy rate and bone volume diminishes over time. Because traditional dentures are supported by the gum ridges, the constant compressive forces on the gums can also contribute to bone loss.
As mentioned, we can refit dentures by lining them with new acrylic material. Eventually, though, it may be necessary to consider a new set of dentures that match the altered contours of your jaw. But continuing bone loss might lead to the same fate for your new dentures as your previous pair.
There’s a relatively new alternative, though, that could provide greater denture stability and help deter bone loss: implant overdentures. They’re actually a union between a traditional denture and a dental implant, a tooth replacement approach introduced over thirty years ago.
With this option, two strategically-placed implants are surgically inserted into the jaw bone. We then manufacture a denture (or retrofit your current dentures, if possible) with fittings that connect to the implants. Once in the mouth, the dentures gain their main support from the implants rather than the gum ridge, which relieves pressure on the bone. And because the titanium implant has a natural affinity with bone, new bone will grow and attach itself to it, increasing its stability and stopping bone loss.
Although more expensive than traditional dentures, implant overdentures are more affordable than individual teeth replaced by implants and are very cost-effective over time. What’s more, they can restore the comfort and confidence to eat, speak and smile that you once enjoyed when you had your own teeth.

Let's say you have a diseased tooth you think might be on its last leg. It might be possible to save it, perhaps with a significant investment of time and money. On the other hand, you could have it replaced with a life-like dental implant.
That seems like a no-brainer, especially since implants are as close as we have to natural teeth. But you might want to take a second look at salvaging your tooth—as wonderful as implants are, they can't beat the real thing.
Our teeth, gums and jaws form an intricate oral system: Each part supports the others for optimum function and health. Rescuing a troubled tooth could be the best way to preserve that function, and replacing it, even with a dental implant, a less satisfying option.
How we save it will depend on what's threatening it, like advanced tooth decay. Caused by bacterial acid that creates a cavity in enamel and underlying dentin, decay can quickly spread into the tooth's pulp and root canals, and eventually threaten the supporting bone.
We may be able to stop decay and save the tooth with a root canal treatment. During this procedure, we remove diseased tissue from the pulp and root canals through a drilled access hole, and then fill the empty spaces. We then seal the access and later crown the tooth to protect it against future infection.
A second common threat is periodontal (gum) disease. Bacteria in dental plaque infect the outer gums and, like tooth decay, the infection quickly spreads deeper into the root and bone. The disease weakens gum attachments to affected teeth, hastening their demise.
To treat gum disease, we manually remove built-up plaque and tartar (hardened plaque). This deprives the infecting bacteria of their primary food source and “starves” the infection. Depending on the disease's advancement, this might take several cleaning sessions and possible gum surgery to access deep pockets of infection around the root.
Because both of these treatment modalities can be quite in-depth, we'll need to assess the survivability of the tooth. The tooth could be too far gone and not worth the effort and expense to save it. If there is a reasonable chance, though, a rescue attempt for your troubled tooth might be the right option.

Oral cancer is one of the more dangerous malignancies people face. But there are ways you can reduce your risk of this deadly disease through changes in lifestyle habits and behaviors.
Two of the better known behaviors for increased oral cancer risk are immoderate consumption of alcohol and the use of tobacco, particularly chewing tobacco and snuff. Eliminating these, especially the latter, can vastly improve your odds of avoiding cancer. Another factor is a strain of the human papilloma virus (HPV 16) that's transmitted sexually, which you can avoid through safe sex practices.
In addition to these lifestyle changes, there's one more you should make to lower your oral cancer risk: adjustments to your diet. Research over the last half century has provided ample evidence of a link between the foods we eat and our risk of all types of cancers, including oral.
The biggest concern is over certain elements in some foods that can damage DNA, the molecular “operating instructions” that regulate the formation and function of our bodies' cells. These elements are collectively known as carcinogens because of their role in cancer formation.
An example of a carcinogen is a group of chemicals called nitrosamines. These form during preservation processes using nitrites in meats like bacon or ham. They're also found in beer or certain preserved fish. To limit your consumption of nitrosamines, you should reduce these and other processed products and replace them with fresh fruits and vegetables, or organic meats and dairy products.
Our DNA can also be damaged by unstable molecules called free radicals that arise during normal cellular function. But there are also substances known as antioxidants that help protect the cells from free radical damage. Many plant-based foods contain nutrients like vitamins C and E that have antioxidant properties, so including them in your diet could help reduce your oral cancer risk.
Several clinical studies over the years have been consistent in their findings that a diet rich in fresh fruits and vegetables can reduce the risk of oral or throat cancers, as well as other forms of cancer. Making changes to your diet in that direction, plus other lifestyle changes, could help you avoid this devastating oral disease.
