"I use one, the stuff it blasts from between your teeth is unbelievable and it's very satisfying seeing all the bits in the sink. My old NHS dentist was very enthusiastic about them. Mouth feels very fresh afterwards.” Sparklingbrook
“I use one and it's great. I can't use floss as it hurts and gets stuck. I can't recommend the water flosser enough.” Charabanctrip
“I love my Waterpik, it's brilliant. Have the one with a tank that plugs into the mains. My husband has really crowded teeth and has never been able to floss, the Waterpik has made a massive difference to his gum health.” Goldenphoenix
“Our dentist recommended. DH loves it and uses it daily; I hate the damn thing because I'm so bad at directing it inside my mouth (part of my lifelong left/right confusion) the squirt gets all over the tiles. When I told dentist he suggested I use it when I'm in the shower, so I do. They do have a positive effect on gum health (dentist says he can see the difference).” 2bazookas
Readers of a certain age will remember an advert for beer that claimed to “refresh the parts that other beers cannot reach”. Well we can confidently say that a Waterpik is like Heineken, but for gums. This nifty gadget is basically a pressure washer for mouths that thoroughly irrigates all the nooks and crannies between your teeth that a normal toothbrush or bit of floss can’t get near, and we are totally here for it. Your thread on the subject was utterly rotten and had us howling at mental images of getting confused by lefts and rights and accidentally jet washing the bathroom or using it on mouldy windows. But the consensus is pretty unanimous and it seems Mumsnetters love their water flossers. So, if better oral hygiene is on your to-do list for 2022, then pop over to Boots where the Waterpik is currently just £37, down from £55, and enjoy squeaky clean gnashers forevermore.
