Abstract (en)
[origin: US4743199A] In a method and a tooth brush for removing plaque from teeth and gums, the mixture of ozone with air of a predetermined ozone concentration is fed into the oral cavity through tubular bristles, provided on the surface of the tooth brush, from a source of the ozone-air mixture. The ozone-air mixture is distributed simultaneously with a dentifrice containing solid particles through which undesired high ozone concentration at spots outside a target spot in the oral cavity is neutralized.
