My gum is inflamed, swollen & hurts around my bottom right wisdom tooth that's half cut through. i'm getting earache and sore throat. is it infected?

Positive: Yes you may need intervention and extraction of teeth and may need antibiotics to avoid further infection pain and the ear it is because nerve endings are stimulated for the root inflamation.

Probably: You likely have a pericoronitis. This is an infection under the gum tissue covering part of that wisdom tooth. You may be biting it with the top tooth as well. Hot salt water rinses and Ibuprofen right away. Get to the oral surgeon asap to get this treated. Infection can get much worse and be life threatening if left too long. Good luck.

Pericorinitis: Contact your dentist for a definitive diagnosis,but it appears to be pericorinitis. An antibiotic may be needed or an extraction may be warranted.

See a dentist: A wisdom tooth that has not fully come in can cause a painful infection. If you are experiencing pain, swollen lymph nodes, earache and it does not go away or if you find it difficult to open your mouth, you should see a dentist for evaluation, x-ray and wisdom teeth removal.
