Study finds depression and anxiety symptoms linked to poorer oral health

ANBAR, Iraq — A new study has identified a direct association between symptoms of depression and anxiety and reduced oral health. Researchers analyzed data from 650 adults using the PHQ-9, GAD-7 and OHIP-14 scales, which measure depression, anxiety and oral health-related quality of life. The findings showed that as depressive and anxiety symptoms grew more severe, participants reported worsening conditions of their teeth and gums. The effect was notably stronger among individuals with severe depression and high anxiety levels. The researchers also reported lower oral health scores among participants over the age of 45 and those from middle-income households. They called on dentists to take patients' psychological state into account during examinations and treatment. Experts noted that stress and anxiety can disrupt hormones and reduce vitamin absorption, weakening the immune system and creating conditions that contribute to oral and dental disease. No further details on the study's publication or funding were immediately available.
