Here's an accessory that I was looking a long time for his gum on curette, which for some unknown reason was not available in France and elsewhere, so thankfully that Amazon is here !!! There is nothing better for regularly made a good teeth cleaning with incredible ease, much better than gels and other products that much damage the teeth and which ultimately are not that effective. I recommend occur for drinkers of tea, coffee and smoking biensur with the agreement of their dentists.
