Middle ear and outer ear infections are common causes of sharp ear pain. An infection of the inner ear, formally called labyrinthitus, may cause sharp pain as well as a loss of balance. People with a bad cold or the flu often experience sharp ear pain.
6. Tooth infection: Sometimes a bacterial infection of the tooth can cause ear in the pain. A cavity in the tooth, chipped or broken tooth, all of these can cause tooth decay allowing bacteria to infect the pulp. The infection most of the time spreads to the bones supporting the tooth and causing severe pain.
