We ordered the handset Oral B Oxyjet 3000 after several years of using the Oral-B Waterjet that always satisfies us. Disappointed at first use: maximum power is the Oxyjet Level 2 Waterjet: cleaning is not effective and insufficient. The electric toothbrush provides too much vibration and is deleterious to a bridge or implant, again the mechanism, instead of truly eliminate the "plaque" concentrated on the neck of the tooth and caused a start of tooth abscess on one of mine after three days of use, despite the habit of strict hygiene. We reuse the old Waterjet and manual brushes. Shame!
