You didn't say if you have a local or general anaesthesia.
Usually, if you remove 1 or 2 molars on one side, local anaesthesia
by way of a nerve block is sufficient. For more extensive
procedures, general anaesthesia may be used and in that case, you
may have had a tube down your windpipe, which may give you a sore
throat.
I guess you probably had LA. If you have a pharyngitis/tonsillitis,
it may be totally coincidental. On the other hand, if you had some
infection related to an impacted wisdom tooth, for example, during
surgery the infection might well have tracked down to the throat
and give you symptoms now.
Most important is to check that you do not have a pre-existent
heart problem (previous rheumatic heart disease, congenital or
acquired valve disorders, hole in the heart...that sort of thing).
If you do, you should have had antibiotic prophylaxis. If not, a
pharyngitis/tonsilitis will get better with symptomatic and if
necessary, antibiotic treatment. I guess you might be already on
antibiotics on account of the wisdom tooth extraction, especially
if it was inflamed.
See your GP if your symptoms persist and he will be able to tell
you what's wrong.
