Vertigo from an infected tooth?

Vertigo: Usually vertigo is from an infection or other disorder in the inner ear canal. It is possible, but unlikely, for an infection from a tooth to spread from the tooth into the ear. You need to visit an ENT physician or a dentist.

Not usually: There are many different causes for vertigo but it is unlikely it is caused by a tooth. I would recommend an ENT that deals with vertigo for a definative diagnosis.
