Hi there - for me manuka was awesome. Because it's antibacterial it actually fights cavities. Strangely enough. It's the bacteria in plaque that causes cavities. (Go figure) I used it after each meal. I would eat, brush my teeth and then use the manuka (1 teaspoon put in mouth - let melt -swish for 1-3 minutes (- it stings- but your mouth feels amazing after.) I would use it when I knew it would be a while before something else went in there then in between I would rinse frequently with the baking soda mixture or flat club soda. It is antibacterial, anti fungal and antibiotic.. Pretty awesome bees I must say. Hugs
