Cinnamon toothpicks not only aid in hygiene, they also help freshen your breath and add a sweet note to the end of any meal. To make strong, fresh-tasting cinnamon toothpicks, you need cinnamon oil. Don't confuse this with cinnamon flavoring extract, which is far less potent. Look for cinnamon oil in health food stores and large supermarkets or ask for it at the counter in pharmacies. While making the toothpicks requires little hands-on effort, you need to start the process at least a day in advance to allow them to absorb enough cinnamon flavor to your liking and to dry thoroughly.
Arrange the toothpicks in an even layer on the bottom of the glass jar or container. Add enough cinnamon oil to cover the toothpicks.
Put on the container's lid. Allow the toothpicks to soak in the oil overnight or for up to one day.
Remove the toothpicks from the container with tongs. Arrange them in a single layer on a nonabsorbent surface, such as a rimmed cookie sheet.
Leave the toothpicks until dry, about one to two hours. Store in an air-tight container.
