By the end of 2001, Sonicare had become the number-one selling rechargeable power toothbrush in the United States. A few months later Optiva Corporation changed its name to Philips Oral Healthcare, Inc. In October 2000, Philips Domestic Appliances and Personal Care, a division of Philips, acquired the company. In 1995, GEMTech changed its name to Optiva Corporation. After several years of research and creating prototypes, the Sonicare toothbrush was introduced in November 1992 at a periodontal convention. They formed a new company named GEMTech to promote a dental hygiene device using a piezoelectric multimorph transducer. In 1987, David Giuliani, an entrepreneur with a background in electrical engineering, met with University of Washington professors Drs.

Individual studies have shown that Sonicare toothbrushes are more effective at removing plaque and reducing gingivitis than manual toothbrushes. In regards to probing depth, Sonicare showed a mean reduction of 0.84 mm from baseline at 6 months, while Oral B showed an average reduction of 0.39 mm. The percentage reduction in inflammation from baseline at 6 months was 31.9% for Sonicare and 18.1% for Oral B. Īn additional study showed that while both Sonicare and Oral B electric toothbrushes do better than manual toothbrushes in removing plaque, reducing gingival inflammation, and reducing probing depths, the Sonicare showed significantly more improvement than Oral B. A 2007 study comparing the two found the rotation/oscillation brush to be more effective in single-use plaque reduction. A second review found no clinical evidence for the dynamic fluid activity of the Sonicare toothbrush being more effective in plaque removal than an Oral-B oscillating/rotating electric toothbrush. However a 2004 review of 29 studies concluded that only electric toothbrushes with rotational/oscillation movement removed more plaque than other brushes when correctly used. Individual clinical research has shown Sonicare toothbrushes to be more effective than comparable Oral-B electric toothbrushes in reduction of gingival inflammation and therefore improvement in periodontal health. Also, there is a Sonicare for kids that has 2 different heads that works with a wide variety of ages. Typically, the sonicare costs over $100 but new models are available for the price conscious consumer. Currently, there are multiple types of Sonicare brushes to appeal to every consumer. The replaceable head is also driven magnetically. Rather than connecting to its charger with conductors, it uses inductive charging-the charger includes the primary winding of the voltage-reducing transformer and the fat handle of the brush includes the secondary winding.
The brush head vibrates at hundreds of times per second, with the latest models at 31,000 strokes per minute or 62,000 movements per minute (517 Hz).
