Healing: I am sorry to hear of your agony. But, other then completely avoiding putting any other product on your face you will have to wait for the body to heal.

Maybe allergy: I'm guessing that maybe you used colgate or crest paste some people are allergic to these. If this what you used, try some antihistamine from the drugstore and vitamin c. A high protein diet and a multivitamin may help healing too.

Natural remedies: You can try using natural remedy such as chamomile tea compress. Can be used cold or room temperature, use clean towel with tea extract and apply on your face for 15 min. You will have to use it 2-3 times a day and apply a moisturizer that you know works for your skin, with no chemicals, additives. If burn is severe you should contact a dermatologist.
