Stevia is a natural sweetener which is used in mouth care products to give products a sweeter flavour without the tooth decay causing properties of refined sugar.
A sweet extract obtained from the stevia plant (Stevia rebaudiana), this popular culinary ingredient is around 30 times sweeter than cane sugar. Consequently, an extract made from the twigs and leaves of the plant is a popular sugar substitute in cooking and baking. Stevia has the added benefit of actually suppressing dental bacteria growth to help keep your gums and teeth clean.
This ingredient is extracted from the stevia leaf, filtered, and purified. The extraction process is very similar to the way ingredients such as vanilla extract are obtained, where they are soaked in alcohol.
