I had finished eating a slice of pizza from a local diner; had eaten some cucumbers shortly after. Due to Chronic Periodontitist, dental picks, floss, and brushing are REQUIRED after each meal. I had noticed IMMEDIATELY AFTER FLOSSING, a "spiral, thread-like particle" had come out, along with a food particle. It was expelled from midline of lower left quad. I had done a "Google" search to see a correlation between cucumbers and dental care and had found an article that will be submitted on "cited" soon after this post.
