Four tongue scrapers, three in silver and one in ivory. These date from around 1850, England. Tongue scrapers such as these were hand crafted personal hygiene instruments, specially designed for the removal of debris which build up on the tongue. The concept of tongue scraping has endured, and similar devices made from metal or plastic are used in modern oral hygiene practices to remove the plaque, food debris and bacterial build ups responsible for halitosis (bad breath).
