Petosan Silent Power toothbrush combines the benefits of brushing with a double-headed toothbrush. Brushing both sides of the teeth in the same motion saves time and is very effective! Two brush heads are included - one small and one large to accommodate all breeds. This toothbrush allows you to reach both above and below the gum line; with 20,000 brush strokes per minute, the Silent Power toothbrush is highly effective at removing plaque. It is recommended to use different brush heads if the brush is to be used on more than one pet to avoid the spread of any diseases. Produced in Norway and designed by a team of Scandinavian dentists and veterinarians (Batteries not included)
