How do i get rid of my mouth ulcer in a day/night? it's affecting how much i eat.

Oral ulcer: Many treatments otc glyoxide anesthetic and antiseptic useful. Salt water gargles helpful regretfully doubt gone in 24 hours.

Laser: Ulcers self-heal in 14 days from onset. If not it may be more serious than just an ulcer. If your Dentist treats with lasers, he/she may be able to eliminate the ulcer. If not, dab a little Milk of Magnesia or Benzocaine in Orabase (Orabase-B) onto the ulcer about 15 minutes before a meal.
