I bought my Ulta 100 a month ago and love this product. My dentist recommended due to my bad flossing technique especially the back teeth. It is amazing even after brushing how many food particles appear in the sink. I highly recommend getting one for preventing teeth and gum disease!
I have only used this product for about two weeks. My teeth look and feel cleaner. Can't wait until I have my next appointment with my dental hygienist to see her reaction.
