Is there a word that describes the tiny pieces of food that gets stuck in between your teeth after eating, and that you get rid of by brushing?
According to Mosby's Dental Dictionary and as suggested by Jim in the comments, the term is food debris:
Particles of food remaining in the mouth after eating which collect in tooth crevices and between the teeth and may contribute to the formation of dental caries.
A proper answer (food debris) has already been given; not right, but related, and suitable for extreme circumstances, is gobbet:
- a quantity of liquid, often in a sticky blotch
- a lump or chunk of something, especially of raw meat
The following single words are also frequently used to describe food that is stuck between the teeth.
a usually small part, member, or trace remaining
something that remains after a part is taken, separated, or designated or after the completion of a process
a remaining part or trace —usually used in plural
I honestly think that no one has concocted a specific word for the pieces of food trapped in your teeth. However, I do suppose that "food debris" will suffice as a solution to those who need a word to describe the subject. Now that I remember, I do suppose I have heard the term "hocker" used before, but I do not recommend it.
