Hate flossing and interdental brushes but use them
me too, my teeth are very tightly packed together, although luckily straight thanks to orthodontics as a child.
Water flossing rinses out particles/debris and (imo) removes more comprehensively tape does, it would probably be good to also floss too if you could (?)
I used to sometimes get a bit of gum bleeding when I brushed but that is far rarer now.
I know you have to lay out £50 and it doesnt replace the need for regular dental check ups but I feel it would pay for itself many times over in fee's for actual dental work
