I know my wisdom teeth are coming in impacted, but right now my mouth is slightly swollen and i can barely open my jaw and i'm in a lot of pain ?

Painful Wisdom: You may have a bad case of pericoronitis. My recommendation would be to get a referral to your local oral surgeon. In the meantime, take a full course of a broad spectrum antibiotic combined with Ibuprofen. You should experience a noticeable reduction in the pain and swelling within 3 days. Be sure to take the full course of antibiotics. But yes, they need to come out.

See a dentist ASAP: When wisdom teeth cause problems, they need to come out. If you are experiencing pain, swollen gums, lymph nodes 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.

Evaluation: Please see your dentist or oral surgeon to have those problematic teeth evaluated. They most likely need to be extracted due to lack of space.

Pericornitis: Sounds like pericornitis - inflammation/infection around a partially erupted tooth. You can get some relief from ibuprofen (tylenol (acetaminophen) not as effective) and warm salt water rinses. A dentist can prescribe an antibiotic to help. Need to consider extracting this tooth when all is back to normal as the condition is likely to recur and may be worse and harder to cure next time.
