welcome in H.C.M.
I have gone through your query regarding jaw pain
after tooth extraction (left molar).
Here I would like to tell you that pain of tooth socket of extracted molar had a tendency to be referred to ear of same side, Secondarily during extraction of difficult impacted tooth
some times temporomandibular joint gets injured and and start paining along with earache.
Therefore it will be better to consult your dentist
or ENT specialist
to manage it.
