I did research and watched you tube videos on how happy people were on this toothbrush. its a bit pricey but I feel like I just came back from the dentist every time. I'm in my 40's and I wear both a night guard and day guard because I grind my teeth. They are not in the best shape for doing so. I also have a perm.retainer on the bottom of my set so its very hard to 'floss' in between teeth and uncomfortable. This toothbrush is awesome. It does both at the same time.
I like the firmness of the bristles, I’d call it medium firm. These come in 2 sizes: full or compact head. The flow of the water is palpable which helps me to direct the flow where I need it.
