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.
There are many possible causes of pain in or around the ear although most patients and even physicians can think of only a few causes. Those causes being allergies, earwax or ear infection, whether it be a middle ear infection (otitis media) or Swimmer's ear (otitis externa).ndeed, this particular cause of otalgia is due to Cranial Nerve 5 that transmits pain involving the jaw to the ear itself. Sometimes the pain/discomfort is due to a non-biologic trigger, like cell phone use (read more about this here). There are many other examples of non-ear causes of otalgia.
