When something tides you over, it keeps you going for the time being.
Example
You take your camera outside on a sunny day, but you have forgotten the lens hood. You make an improvised hood out of a roll of paper and an elastic band. That tides you over until you get the hood.
It means to have just enough to hold you over until you get what you are actually waiting for. Such as, getting bread before getting appetizers to "tide" you over until the apps come out.
Although, I don't know if this is actual proper usage of the word "tide" or just one of those stupid things people started saying that caught on...

There is no idiom "the tide turned over." There is a saying that "the tide turned," but it's not an idiom because you can figure out what it means by thinking. Tides "turn" when they shift from high tide to low tide - the currents either go toward the beach or away from it depending on what tide is coming up. People say "the tide turned" or "the tide will turn" to mean that situations in life are changing, just in the same way that the tides change.
I certainly hope that this ten dollars will tide me over until payday. I will have to move my beach towel before the high tide arrives.
Actually the phrase is "tide you over" and the origin I'm not sure of. For instance if someone came asking for a certain amount of money, I might respond, How much can you get by with. If the respondant state a lesser amount in order to make it till a later date, then I would give the person the lesser amount just to "tide them Over" or help them until something else came along to help them. Hope this helps
