Dentists suggest primary care doctors pay more attention to signs of illness that might appear in the mouth. From overlooked gum disease to suspicious lesions, oral health can provide a critical window into broader health issues. Some oral problems like oral thrush (linked with diabetes), mouth ulcers from Crohn's disease, and gum disease (linked with cardiovascular issues) can be detected through regular checkups. For osteoporosis patients, certain medications (like bisphosphonates) can cause dental issues. Early detection of oral cancer, especially those related to HPV, is crucial. Hence, doctors should recommend patients see a dentist when starting new medications. Maintaining good oral hygiene, like regular dental visits, daily brushing, and flossing, helps in overall health.
