Food spoils/goes rancid/goes off when microbes on the food begin to grow, and reach levels which would make eating the food unpalatable/potentially harmful.
Most microbes love living in an environment which is slightly warm, with a food source and some liquid (the last two things are generally provided by the food item they are living on). Putting your food in the fridge or freezer reduces the temperature which the microbes live in, hence they cannot breed as quickly so your food remains fresher for longer.
If food particles remain in the teeth , it can spoil your teeth quickly.
Food can spoil anywhere. If it is left in the temperature danger zone, food will spoil faster. The temperature danger zone is between 145 degrees and 45 degrees.
