Start low
Begin with the lowest pressure level. The sensation is new, and comfort matters more than intensity in the first days.
Move up one level at a time, only when the current one feels easy.
Lean over the sink
Lean forward, place the tip in your mouth, then switch on. Keep your lips loosely closed and let the water fall into the sink.
Follow the gum line
Aim the jet along the gum line and pause briefly between each tooth. Work from the back teeth forward, outside first, then inside.
If you have had oral surgery or your gums bleed, ask your dentist before you start.
After use
Empty the tank and leave it open to dry. A dry tank stays fresh.
