Does the secretion from the gums, which has a taste when the tongue passes over it, affect the validity of fasting and prayer, especially with increased saliva when trying not to swallow it?

Interpreting the condition of the gums and their treatment requires consulting a specialized doctor. As for swallowing saliva, it does not invalidate the fast. However, if the gums secrete pus or blood, swallowing it is forbidden and invalidates the fast, because the mouth is considered like the exterior, and swallowing a part of something impure breaks the fast.
