About 3 days ago i had a discomfort on the inside of gum it hasn’t gone away and after paying more attention noticed a bright red patch maybe a couple inches in size on my gum underneath the wisdom tooth . I am planning to see a dentist asap but would like to see if I’m over reacting . Pictures is the best I could take since It’s right next to the tongue. I know I’m long overdue for a dental visit please advice .
