I love this technique of turning jet. This is both more comfortable and less risky than standard nozzles that give a very powerful and localized stream, which makes the gums bleed profusely if you are not used ... or throw a little soft, which cleans not much. As the jet is very thin, it has no trouble slipping between the teeth and hunt food jams. Of course, it does not replace flossing but it leaves a much cleaner mouth than brushing followed by a single rinse with a cup of water. After about a year, turning jet eventually caught and this is the time of replacement. But within the cannula 2, that is less than a toothpaste tube or an Oral-B Sonic Complete brush.
