Nomad, I hope your fears have been eased by the above posts from knowledgeable members.
HPV+ is something about 80% of the population will get at one point or another, most people can clear this from their bodies and it does no harm. At this time hereditary links for oral cancer have not scientifically been established. Links between a person having cervical
HPV and it turning into oral
HPV have not been proven either.
Tooth pain can cause alot of pain in a persons neck, jaw and ears. Since it hurt for a while before the tooth extraction, you need to give your body time to heal. Sore throats can be caused by many things including post nasal drip. Depending where you are located, this time of year is when it bothers many people. Im not dismissing your symptoms at all. Im glad you are being watchful. I suggest waiting at least 2 weeks and if you still are feeling the same to then seek out an ENT who is experienced with head and neck cancer. Not all ENTs do this, some focus primarily on doing tubes in childrens ears.
Best wishes with your recovery from the extraction. I know it can be very painful for a while.
