Inflammation: When gums get swollen and itchy it is because there is too much plaque and buildup. Usually they bleed when touched too or when brush and floss. Sounds like it is time to see your favorite dentist for a good check up and cleaning.

Hard to say: This could be a simple case of gum disease or something more serious. You really should see a dentist for an examination.

Consult dentist & MD: At 19 i would want you to consult both a dentist and physician with those symptoms. Could be gum disease or even a systemic health condition. Do not wait!

Allergic reaction?: What you described could well be an allergic reaction. However, it could also be something else. I would suggest that you calk your physician and discuss your symptoms and see how this should be handled. If the symptoms worsen, or you have trouble breathing, call 911.

Needs to be seen : These types of symptoms require a one on one clinical exam by a dentist. There are many possibilities, both of dental and medical origin.
