Using Toothpicks

What is the rule on using toothpicks after the meal for a person who wants to fast the next day?

For a person who wants to fast the next day, it is not obligatory to remove the bits of food by a toothpick even in case he thinks not doing so may lead to their entering the throat. Later, if the bits enter the throat inadvertently, the fast is not void. Of course, if he is sure that not using a toothpick leads to their entering the throat, it is obligatory to use a toothpick and in case he neglects it, his fast is void if the bits enter; rather it is void, by obligatory caution, even if they do not enter.
