What is the best practice for using an oral irrigator?

The recommendation to direct the stream perpendicular to the long axis of the tooth is based on the principle of optimizing the removal of debris and biofilm from the gum line and interproximal areas. When the irrigator's stream is positioned this way, it can effectively penetrate the pockets between the gum and the tooth, dislodging food particles and bacteria that contribute to gingivitis and periodontal disease. This approach maximizes the efficacy of the irrigator in promoting oral hygiene.

Using an oral irrigator improperly, such as directing the stream towards the gum line at an angle or in a circular motion, may fail to deliver the cleaning action needed in interproximal spaces or may even irritate the gum tissue. Additionally, relying solely on the lowest setting could limit the device’s effectiveness in cleaning, as sufficient pressure may be necessary to effectively remove debris. Therefore, positioning the stream correctly is essential for achieving optimal results in oral irrigation practices.
