Does a "teething" rash look any different from an "allergic" rash or does it depend on the kid/offending food/particular tooth, etc.?
DS has a funny amoeba shaped rashy red spot on the fatty pad of skin above his penis that comes and goes. It first emerged with teething, I believed, and he still appears to be teething on and off. The only other possibility is a reaction to goats milk yogart and cheese which he eats daily or every other day... how can you tell what's what?
