Overall Health Concerns — In many respects, your oral health can be seen as a mirror of your general health. Some dental problems may reflect issues in other parts of your body, and vice versa. For example, untreated oral infections can lead to poorer control of diabetes, an increased incidence of cardiovascular disease, and complications during pregnancy. General dentists are trained to identify these and other issues, and offer appropriate treatment or referral when needed. One special concern is obstructive sleep apnea, a potentially deadly condition that can sometimes be treated with an oral appliance. General dentists can also offer nutritional counseling, advice on tobacco cessation and general health and wellness information.
