I showed him the device. My dentist, I've known for over 20 years himself user of a dental jet, said that the idea is very good. Compact and highly efficient. I am a consumer of nuts. After thorough brushing (electric brush) this device still flushes residues while I have a very tight teeth. In the end you feel good cleanliness. A small additive in water and is super quiet at hygiene! It is a good investment especially when you realize that his dental heritage is not renewed. To be compared dental costs avoided and pleasure to say hello to her right dentist for scaling union. We will love her dentist!
