Does moistening the lips with the tongue and swallowing the saliva break the fast, and what is the ruling on the days during which this was done while suffering from obsessive-compulsive disorder? And does touching things with the teeth or putting a finger in the mouth break the fast?
Excessive spitting is a form of waswas (whispers from Satan) that should be abandoned. Moistening the lips with saliva is permissible and does not invalidate the fast. Similarly, holding something between the teeth or inserting a finger into the mouth does not invalidate the fast.
