Mr. Hong has crooked teeth. For example the neck of a top canine (Fig.1 *) is too high to be brushed well so that the gums are reddish. Before braces, he is told to use water flosser. In ten days, the gums are not so "angry" (Fig.2). He is happy to braces on (Fig.3). It is expected that his oral hygiene will be perfect with practice of water flosser and good alignment of his teeth in 1 to 2 years.
