<p>On a journey, at a picnic, or in sports there is not always an opportunity to clean ones teeth after a meal and wash the hands before and after the tooth cleaning operation. The use of a toothpick is not sufficient and can lead to an injury of the gums. The new travelling set contains two moist tissues to be used before and after the tooth cleaning and dental floss suitable for a single use. The items are packed in order to form a soft and space saving unit and can be conveniently carried in a trouser- or shirt pocket.</p> |
