In brief: Sugar

Bacteria in your mouth cling to your tooth & if fed by sugar they produce acids that erode your tooth & result in decay ( a cavity).

In brief: Combination

Tooth decay comes from a combination of food debris left on and in between teeth and bacteria that use the food debris and create acids that damage tooth enamel and dentin.

In brief: Bacteria and sugar

Decay is caused by bacteria which are naturally occurring in your mouth.
When the bacteria are fed sugar, either simple like sweets or complex like bread or sugar, they produce acid which eats into the tooth.

In brief: Certain Bacteria

You need the combination of of a few things.
1) bacteria in your mouth. The better you can control the bacteria count the less likey you are to get decay. 2) carbohydrate. The bacteria use and produce acid as a by-product. Sugar is worst 3) a susceptible tooth surface. Smooth sufaces and self cleansing areas of the mouth are less prone to cavities...Sealants can fill in groves and pits 4) time.
