swallowing excessive saliva while fasting will break your roza or not?

Asslam o alaikum to all of my brothers and sisters.. Well my question is that i have searched in google that when a person swallow his saliva while fasting is this breaks persons fast..? Everywhere it shows that swallowing saliva will not breaks persons fast but whenever i do sehri after sehri my mouth suddenly filled with water till iftari so is this ok to swallow that much saliva?.. Most people do not fell that much saliva in their mouth as i do..Mostly i spit out but after 2 or 3 mint again my mouth fill with water.. Iam not good in english but i hope you get whatever i said. My question is only that is this ok to swallow that much saliva? But it's very hard for me to not to swallow saliva while praying salah in the month of ramadan.. We don't use tissues while praying salah so i swallow my saliva because there is no any other way of spitting out while praying salah specially in the month of ramdhan
