Rye Tooth Powder
April 28th, 2015
Rye contains carbonate of lime, carbonate of magnesia, oxide of iron, manganese, and silica, all suitable for application to the teeth. Therefore, a fine tooth powder is made by burning rye, or rye bread, to ashes, and grinding it to powder by passing the rolling-pin over it. Pass the powder through a sieve, and use.
