The following is an excellent tooth-powder:
Take of finely-powdered Peruvian Bark;
„ Prepared Coral;
„ Prepared Chalk;
„ Myrrh, of each half an ounce;
„ Orris root, a quarter of an ounce:
Mix them well together in a mortar, and preserve the powder in a wide-mouth stoppered bottle.
The teeth ought to be well brushed with the above tooth-powder every morning.
If the teeth be much decayed, and if, in consequence, the breath be offensive, two ounces of finely-powdered charcoal, well mixed with the above ingredients, will be found a valuable addition.
