Oral Cancer

Tobacco's greatest threat to your health may be its link to oral cancer. The American Cancer Society reports that:

* About 90% of people with mouth cancer and some types of throat cancer have used tobacco. The risk of developing these cancers increases as people smoke or chew more or for a longer time.

* Smokers are six times more likely than nonsmokers to develop these cancers.

* About 37% of patients who continue to smoke after cancer treatment will develop second cancers of the mouth, throat or larynx. This compares with only 6% of those who stop smoking.

* Tobacco smoke from cigarettes, cigars or pipes can cause cancers anywhere in the mouth or the part of the throat just behind the mouth. It also can cause cancers of the larynx, lungs, esophagus, kidneys, bladder and several other organs. Pipe smoking also can cause cancer in the area of the lips that contacts the pipe stem.

* Smokeless tobacco has been linked to cancers of the cheek, gums and inner surface of the lips. Smokeless tobacco increases the risk of these cancers by nearly 50 times.

Implant Failure

Implants can replace lost teeth in people who smoke. However, smokers should know they have an increased risk that the procedure will fail.

"Studies have consistently found that patients who smoke have more implant failures," Dr. Albert says. Smokers who are considering getting a dental implant need to realize this risk, he says.

"Before getting implants, consider seeking counseling and support to help you quit smoking," he says.
