teeth, slowly following the gum line. The water jet should be directed between the tooth spaces, surfaces above the gum line, stopping momentarily at the area to be cleaned. In the case of hard-to-reach areas such as when using braces, in gum pockets, the angle of the nozzle can be changed. Criticism Dentists classify the oral irrigator as a wellness product because it cannot replace medically sensible brushing and flossing. There is only a possible improvement in blood circulation in the gums due to the massage effect. On the other hand, there is a risk that food debris will get into the tooth pockets due to improper use ("flushing the tooth pockets") and damage the teeth and gums there. Because of this risk, most dentists do not recommend the use of oral irrigators. It is also not advisable to use an irrigator if you have gum disease or have had a tooth extraction. However, other studies have shown that oral irrigators are better at removing plaque than flossing. See also Dental floss References Dental equipment Oral hygiene
