As you can tell, one of the byproducts from both reactions occurring in the different types of baking powder is CO2, or carbon dioxide (www.howthingswork.com). The use of baking powder in toothpaste is attributed to the bicarbonate, which can reduce the acidity in plaque, thereby reducing tooth decay (dentistry.about.com).
