Is there a cause-and-effect relationship between good oral health and good heart health? While dentists have long known there is a relationship between oral health and general health, scientists are now trying to determine how closely oral health and heart health are related.

Current research suggests a link between severe, chronic gum (periodontal) disease and cardiovascular disease, stroke, and bacterial pneumonia.

"As is often the case with new risk factors," says William Haynes, MD, UI pharmacologist, "studies are not yet definitive. We're not certain why there is a relationship, but there are several possible explanations."

The leading theory is that bacteria from gum disease enter the bloodstream and attach to fatty deposits in blood vessels, contributing to blockage of the vessels and leading to heart disease.

What can you do to reduce your risk? The answer is simple:

• Keep your mouth healthy
• See your dentist regularly
• Brush your teeth at least twice a day
• Floss regularly
• If your dentist discovers gum disease, ask what treatments are available to control and reverse the disease

Pediatric dentistry

The old saw is still true-brush your teeth to prevent tooth decay. Today's pediatric dentists, specialists in caring for children's teeth, recommend that children make their first visit to the dentist by age one or within six months of the arrival of the first tooth. Introduce your child to a toothbrush early-as soon as teeth arrive and start brushing your child's teeth with a soft-bristled brush. Proper care of your child's "baby" teeth is important for the health of your child's permanent teeth.

Geriatric dentistry

Regular trips to the dentist are not just for the kids. Good oral health is important among the elderly as well. They are more susceptible to systemic conditions, making it easier to develop oral diseases that can lead to problems eating and talking, and a marginal quality of life. Managing dental care for the elderly requires not only an understanding of the medical and dental aspects of aging, but of factors including walking, independent living, socialization, and sensory function.

Did you know?

Your tongue is the home of some nasty bacteria-solobacterium moorei- responsible for up to 90 percent of chronic bad breath. Brushing twice daily and using a tongue scraper can help eliminate bad breath.

The boomer generation will be the first where the majority will keep their natural teeth throughout their lives thanks to water fluoridation and fluoride toothpaste.

Plaque is a film of bacteria-streptococcus mutans and anaerobes-that cover teeth causing tooth decay and gum disease. Saliva doesn't penetrate built-up plaque and can't neutralize the acid produced by the bacteria. Regular flossing and brushing help keep plaque under control.
