Please do encourage your friend to join, at least read and research here. Salt/baking soda in warm water works well to ease the pain. The doctor can prescribe liquid lidocaine to ease the pain. Doctor can also prescribe something called magic mouthwash that contains ingredients to sooth the mouth.

good luck,
