In 1987, David Giuliani, an entrepreneur with a background in electrical engineering, alongside 2 University of Washington professors, Dr. David Engel and Dr. Roy Martin, formed the company GemTech, to promote a dental hygiene device using a piezoelectric multimorph transducer. After several years of research and creating prototypes, the Sonicare toothbrush was introduced in November 1992 at a periodontal convention in Florida.
In 1995, the company was bought out by Philips, and re-named Philips Oral Healthcare, Inc. Testament to the success of the technology used, the end of 2001 saw Sonicare become the number-one selling rechargeable power toothbrush in the United States. In 2003, in order to reinforce the success of its Sonicare toothbrush Philips began rebranding its growing range as "Philips Sonicare". Multi award-winning distributor Baby Brands Direct offer a select range of children’s power toothbrushes and replacement brushes for pharmacy and nursery stockists. Philips Sonicare say of their range, “After 20 years, we're still the #1 recommended sonic power toothbrush brand by dental professionals worldwide”.
