I'm on antibiotics for wisdom tooth abscess, goin away in 3 weeks time ( flying) might not be able to have it out before i go away, can i still fly?

Probably: As long as you get the abscess under control you should be fine to fly. Get a back-up prescription for antibiotics and pain meds just in case. Worst case scenario, delay your flight until you get treatment.

Get it done: Antibiotics are very helpful but you have to address the root cause of the infection to ever be truly safe. A month on antibiotics isn't the best way to solve this. Follow your doctor's recommendations and get the extraction rather than putting it off.

Priorities: Make it a priority to get it out NOW. Antibiotics do not guarantee that you will not swell up and be in terrible pain when you are away from home. Don't know where you are traveling to, but better to be safe than sorry. All the best...

Sooner better but...: The best person to answer that question would be the dentist who actually examined you, saw the x-rays of the tooth, knows your medical history, can follow you over the next few days, etc. Asking that health care professional for his\her advice makes more sense than posting a general question to doctors, who can't see you and have to make educated guesses with little knowledge of the specifics.

Yes, you can fly: However, if you rely on antibiotics or other not a definitive treatment, the pain and tooth infection always will come back. Dentist will treat a tooth infection by treating the cause and getting rid of the infection. Do not delay. See any dentist ASAP. Good luck.
