Some people use toothpicks to try to remove trapped food from between the teeth and other people use dental floss to try to do this . Dental floss is very often recommended by dentists as safe for flossing teeth , so it is probably safe to remove food from between the teeth using dental floss , since it is more or less the same activity as flossing is . If the floss is too thick for the space between a pair of teeth then it will be difficult or impossible to get the floss down between the teeth .
