Abstract
We present three cases who presented to the emergency department with severe complications of dental infections: Ludwig's angina, necrotising fasciitis and peritonsillar abscess. All of our cases presented at the beginning of COVID-19 pandemic, with complications of dental infections. They delayed their dental treatment due to the pandemic. The airway management was difficult in our cases. Their mortality risk increased due to complications. We aimed to draw attention to complicated odontogenic infections which are rarely seen in emergency department in the past, however started to show up increasingly particularly at the beginning of the COVID-19 pandemic.
