Have gehohlt me after long year of the manual and about 3 years Oral B standard brushes a Sonic sonic brush. For years, tells me my dentist 'press too hard on the toothbrush! Scrub away the tooth necks ....! " I knew this, but whether manually or using the "normal" electrical Oral B Brush - I always made print. Now with the new, completely different designed Sonic brush everything is different! Combined with the Oral B Sinic brushes and cleans the brush so good, so easy, so intense that I did not come to pass on the toothbrush pressure on the teeth to the idea. Simply slide humming and vibrating slightly over the teeth. Perhaps this is due to the slightly heavier body toothbrushes compared to Oral B. Anyway - it works! I am totally satisfied with this Zahnbürten of Oral B Sonic and can recommend them in good conscience.
