All was well for about 14 years, and then around 2003, the Gore company sold their Glide floss to Procter and Gamble (abbreviated here as PG). For about a year or so, Gore continued to manufacture Glide for PG's Crest floss product. While Gore's factories were making it, the anti-shredding quality of the floss remained. After a year or so, manufacturing control went back to PG, and Crest brand floss degraded to be merely shred resistant.
