What is Pumice?

Pumice is formed when lava containing high levels of gases and water erupts from a volcano. The escaping gas bubbles make the lava frothy.  When the gas-rich froth of glassy lava solidifies rapidly, a very light and porous volcanic rock is formed giving the cooled pumice its light density and pocked appearance.


The gritty texture of pumice makes it ideal for polishing smooth surfaces. The outer layer of your teeth, called the enamel, is the hardest substance in your body. When the surface of your enamel becomes scratched or pitted, plaque and bacteria have more places to hide and a rougher surface to cling to. When your teeth are polished with pumice powder – which is often mixed with a flavoring agent – it removes the plaque and bacteria and smooths the surface of your teeth.


In addition to removing plaque and bacteria, Pumice powder can also polish out stains that occur when your teeth react with the foods you eat and the beverages you drink. It also takes care of discoloration from smoking. Having your teeth polished professionally with pumice powder also gets you to a dentist’s office on a regular basis. This gives your dentist a chance to check your mouth for signs of cavities, gum disease or oral cancer.


The pumice powder that your dentist uses is formulated especially to be used on teeth. Don’t ever attempt to save money or time by cleaning your own teeth with a pumice powder intended for other uses.
