Oral health linked to brain aneurysm risk

« Back to Dental

A Finnish study suggests diseases of tooth-supporting tissues, such as severe gingivitis and periodontitis, appear to increase the risk of developing and rupturing a cerebral artery aneurysm. Around 2%–3% of adults have a cerebral artery aneurysm, which, if ruptured, can cause a life-threatening subarachnoid haemorrhage. The findings by dentist and oral and maxillofacial surgeon Joona Hallikainen highlight the particular importance of maintaining good oral health for individuals with unruptured aneurysms.
