In summertime I would cycle water once every month, better once every two weeks, if kept at floor level, covered up and not in the trunk. Winter, one to three months. Probably safe longer than that but that is what I would do.
Food is a problem in the summer unless it is dehydrated. Canned stuff will take alot without going off, but I am uncomfortable eating even canned wet items that have sat in a hot car more than a day or two.
I would store bone-dry staples in the car in well sealed and dehumified containers. Like rice, dry beans etc.
Get something jammed down in between your teeth and into the gum line and sometimes a piece of floss will save the day without the need to go poking something else in there and risking further injury, infection etc.

Not so fast ...-Your teeth won't fall out if you don't floss them for 3 days.
