Do binkies cause skin irritation by mouth?

Indirectly possible: This would really be a 'drool rash' caused by the shield of the binky allowing saliva to stay trapped next to the skin, not something caused by the binky its self. Often when infants are teething they make excess saliva resulting in a drool rash on lips, cheeks and/or necks. This would happen even without the binky if they have lots of excess saliva.
