Yes, get to the dentist or emergency care.
You'd need to see a doctor or dentist to find out for sure. It's difficult to tell from your description, but other possibilities could be a sinus infection(can cause similar pain to toothache) or the lymph node behind your ear swelling.
Sounds like an abscess. Dentist or Oral Surgeon as soon as they can see you.
