Oral irrigators, also known as water flossers or dental water jets, are devices used as a complement to routine oral hygiene. They function by emitting a pulsating jet of water that helps remove food debris and bacterial biofilm from interdental and subgingival areas, which are frequently difficult to reach with traditional brushing alone.
Available scientific evidence suggests that oral irrigators can bring significant benefits to gingival health. Some studies have concluded that, although irrigators do not demonstrate a significant reduction in visible bacterial plaque, there is a positive trend in the improvement of gingival health, namely in the reduction of inflammation and gingival bleeding, particularly in people with dental implants, orthodontic appliances, or special needs.
In patients with fixed braces, these appliances make the effective removal of bacterial plaque difficult, increasing the risk of gingivitis and caries lesions, making irrigators a good complement that can improve bleeding and gingival inflammation indices.
Despite the identified benefits, oral irrigators do not replace toothbrushing or dental floss. Their use is recommended as a complement to daily oral hygiene, especially for people with greater difficulty in interdental cleaning. The effectiveness also depends on the correct and regular use of the device. In conclusion, scientific literature demonstrates that oral irrigators have a positive impact primarily on gingival health, reducing inflammation and bleeding. However, it must never be forgotten that their use is merely a complement and should not be used as a substitute for daily brushing and the use of floss or interdental brushes.
