It depends on the cany, authorities say. Jelly beans and caramel won’t do it, but peanut butter crackers, potato chips, and salted crackers are just a few of the foods that are most likely to cause tooth decay.
How? Simple carbohydrates sugars are easily washed out of the mouth by saliva, while complex carbohydrates, found in crackers and potato chips, stick between the teeth for several hours, thus becoming a source for the bacteria that causes tooth decay.
I addtition to potato chips and crackers, other offeneders include oatmel cookies, cereal flakes coated with sugar, puffed oat cereal, and cream-filled cookies.
The least stick foods, and therefore the least likely to cause tooth decay, are apples, bananas, hot fudge sundaes, and milk chocolates bars.
