Can a cavity cause laryngitis and trouble breathing? I have had symptoms off and on for almost a year. Now worried because on antibiotics for pneumonia (although I believe it was from allergic reaction to foods-a norm for me). But, the laryngitis has been off and on for almost a year. thanks! -amy
Hi. Thanks for the query. A cavity is not commonly seen to cause Laryngitis or breathing difficulty, however if the infection in tooth is severe and there is pus discharge then it can cause throat infection and can probably cause Laryngitis. But if there is just a cavity with no pain in tooth then your symptoms are not due to the tooth. So it is advisable to consult an Emergency room and get evaluated, and they can advise you to get a chest x-ray done to rule out lung infection or other possible pulmonary diseases and other causes. For now continue taking antibiotics and along with it do warm saline gargles. Hope this helps. Regards.
