One bottle of Odol with a circa WWI reproduction label. The bottle is real Odol, imported from Germany and is full of concentrated mouthwash.
Unlike other mouthwash products at the time, Odol was a mouthwash concentrate and was meant to be diluted with water.
Odol was the first commercially produced antiseptic mouthwash, created in the late 1800s by German Research Karl Lingner. By 1912, the product was also sold in France and the US. The bottle has changed very little over the years, becoming only slightly more round. The cap switched from metal to plastic sometime in the 1930s.
Dating Odol bottles is a bit of a challenge because the bottle varied only slightly for many decades. We used several 1912-1913 ads to determine the correct bottle for the era. We’ve seen bottles marked as WWI with very round letters, however, these are from before 1900. The block style logo dates back to the turn of the century.
