Xylitol is a naturally-occurring sweetener found in vegetables, fruits, berries and mushrooms. Xylitol is best known for its cavity fighting abilities. Xylitol sweetener looks and tastes like sugar. The American Dental Association states that xylitol has been proven to reduce tooth decay in the 2006 study "The Use of Sorbitol and Xylitol Sweetened Chewing Gum in Caries Control." Xylitol works by reducing cavity-causing bacteria in the mouth. The United States Department of Agriculture has approved xylitol as safe for human consumption. Make your own xylitol toothpaste at home with a few basic ingredients.

Fill your sink with hot water. Place the jar of coconut oil in the water and let it melt for about five minutes. Pour 4 tbsp. warmed coconut oil into the mixing bowl.

Add 6 tbsp. baking soda to the mixing bowl. Stir thoroughly with a wooden spoon until the mixture forms a paste-like consistency.

Mix in 1 tsp. of xylitol and five to 10 drops of peppermint oil. Add eight to 10 drops of oil of oregano if using. Stir mixture together with a wooden spoon until smooth.

Spoon xylitol toothpaste into an airtight container and store at room temperature. Toothpaste will stay fresh for about six months.
