Hello and welcome to HCM,
Wisdom teeth usually erupt in the age group of 18 to 25 years . In your case as your other teeth are hurting and mouth is sore i can suspect eruption of wisdom teeth as your other oral habits are good with no other oral problems.
To get it confirmed to need to get an OPG radiograph done which will show the position of all the wisdom teeth if any, upper two and lower two, their position in the oral cavity in relation to the jaw bone and adjacent teeth.This will help your
dentist to plan treatment for you.
If your wisdom teeth are impacted in the bone,they wont erupt in proper place and will disturb adjacent teeth and tissues, there is a chance of infection so better get it removed surgically.
take care.
