The dentist is a key member of your personal medical team. Patients should be open with their dentists about all of their health conditions because some may require special medication or treatment. For example, patients with certain heart conditions may require antibiotics before dental treatment. Also, they may require tailored treatment to prevent excessive bleeding if they are taking a blood thinner. Dentists can also monitor the affects oral disease can have on a health condition. For instance, dentists are on the lookout for the development of gum disease in pregnant women (Periodontal disease can result in premature, low birth weight babies). Sharing health conditions also helps prepare the dentist in case of an emergency (eg epilepsy). Be sure to reveal any changes in your health history at every dental visit to ensure optimum, uncomplicated care. Make sure you tell the dentist if you have any of the following conditions: AIDS/HIV Any heart-related conditions, including congenital heart defect Asthma Any allergies, including allergies to latex Cancer Diabetes Eating disorders Epilepsy/seizures Knee, joint or hip replacement surgery Pregnancy If you smoke or chew tobacco
