Boxed tube of "Clinomyn smokers toothpaste", by Trentham Laboratories, England, 1971-1975
The nicotine and tar in tobacco smoke causes yellow staining on the teeth. Toothpastes like this one were advertised “to keep teeth free from tobacco and other stains without harsh abrasive action”. Originally made by Trentham Laboratories, Clinomyn toothpaste is still available today. Toothpaste and toothpowders only began to be used in Britain from the 1700s, becoming increasingly popular in the 1840s.
