The first SP i ever saw was studying to be a nurse, i was very nervous and all about this as well as i heard hiv or SIDA as we call it in french could be transmitted this way. She said it would need like 1000 liters of saliva to be a sligh risk. Its true tough that a bad cut or somthing having to do with BLOOD is more risky, but saliva is not really an issue.
Personally so far i never catched anything, so i would say if the risk is there, its very small. Would suck to catch something too, but most diseases can be threated, at least the one you may get trough oral.
