I have 3 unopened cans of Caroid Tooth Powder that have never been opened. My Dad worked for Breon Labs which made and sold this tooth powder. When I got married in 1961 I took these 3 cans with me and have kept them under the bathroom sink all these years. Growing up my sister, brother & I hated using tooth powder and were so happy when we would go to my grandmothers and use Colgate tooth paste. What a sweet walk back in time and memories.
Caroid tooth powder was made by Breon Labs, a division of Sterling Drug. When I worked with them in the 1960's, we had a line of Caroid products which all contained a proteolytic enzyme called papain for breaking down protein. We would place a raw egg in a cup and sprinkle Caroid powder on it; quickly the protein in the egg would break down in the cup. The products ,except for Caroid and Bile, were very low sales volume and not marketed. When Sterling was dissolved, I do not know were the Caroid line was sold.
I used Caroid in 1945, in the USA. Really did a great job! Wish it was still for sale.
"Not the same product I used. It was Caroid tooth powder in a white and blue can, by Colgate (I think), or was it Proctor and Gamble. It worked like a charm. Since they quit making it about 15 years ago. my teeth and dental exams are terrible. I have no control over my tartar condition, etc., anymore. Please, make it again!!!!"
Papain, the papaya enzyme was the effective ingredient in Caroid toothpowder. Very effective. Then the company took papain out of the mix for some reason. Not sure when or why that was. Maybe they wanted to save money with cheaper ingredients. Caroid then became just another useless toothpowder, lost customers, went out of business. So what you should do now is find a good source of papain powder and mix your own dentifrice. Duckduckgo is the best search engine, you will find many sources for papain there.
I can remember being fascinated as a little kid while watching my father using Caroid to brush his teeth. What are the Caroid ingredients? Does it say on the box or can?Thank you.
