In brief: Ear pain

Depending on which tooth was treated, particularly an upper back molar, the infection could cause ear pain.
If the tooth had a root canal and you are still having ear pain, check back with you dentist. There may be residual infection, or you may have a different dental problem (another tooth or TMJ disorder). If there is no other dental disease, see an ENT specialist to check you ears.

In brief: Root canal ear pain

It is common to have radiating pain to the ear.
The toxins in an abscess tooth irritate the tooth nerve which travels to your brain. The nerve goes through an opening near your ear. This can make your ear hurt too. The bacteria don't cause pain, it is the toxins they produce onto the nerve.
