Not every patient adopts the "gold standard" of oral hygiene, i.e. toothbrush combined with dental floss and interdental brushes. It is therefore sensible to have a recommended alternative to hand. In these cases the water pick can be considered a complement to tooth cleaning. The following study overview shows that the water pick is much better - i.e. more effective - than its reputation suggests. The author carefully examined a large number of studies and assessed their results. This indicated, among other things, that water picks used in addition to toothbrushes had a positive effect against gingivitis and that they are the method of choice for orthodontic patients.
