An oral irrigator comprises a handle housing defining a cavity, a tip removably connected to the handle housing, and a tip release assembly connected to the handle housing. The tip release assembly comprises a tip eject button slidably connected to the handle housing and movable between a first position and a second position, and a latch connected to the handle housing and positioned within the cavity. Movement of the tip eject button from the first position to the second position moves the latch laterally across the cavity from an engage position to a disengage position.
