You then create the depletion charge based on actual units of usage. Thus, if you extract 500 barrels of oil and the unit depletion rate is $5.00 per barrel, then you charge $2,500 to depletion expense.
âXylitol helps prevent cavities because bacteria that cause tooth decay cannot utilize it to grow and cannot metabolize it to produce acid. Xylitol is most effective in gum or mint form and should be consumed three to five times daily for a total of 5 grams per day.
Another way to reduce your risk of cavities is through the use of fluoride, which strengthens teeth. A dentist can evaluate your risk of caries and then suggest appropriate fluoride treatments. Fluoride in water strengthens teeth from within, as they develop, and also on the outside.
