The white inside portion of an orange peel, called the albedo, contains a number of compounds including vitamin C, limonene, glucarate, pectin and soluble fiber. Limonene, also called d-Limonene, is a natural solvent cleaner that is extracted from the orange peel and used commercially in a wide variety of cleaning products. Unlike the fruit itself, orange peels do not contain citric acid, which can erode tooth enamel over time.

Using Orange Peels:
The process of tooth whitening with an orange peel is simple. Wash the orange to remove any dirt. Peel the orange and rub the albedo over your teeth. Rinse your mouth with water or brush your teeth. Repeat as desired with a fresh piece of orange peel. Discard the orange peel after use. Orange peels that are commercially grown may contain pesticides and herbicides; nutritional scientists recommend you choose organically grown oranges.
Grind dry orange peels and bay leaves into a powder. Mix this powder with some water and make a toothpaste mixture with which you will brush onto your teeth. This can also help you stave off other dental problems such as gum disease and cavities.
