I've noticed the same thing with replacement heads wearing out fast—honestly thought I was doing something wrong too. For anyone budget-conscious, I've found buying generic-brand heads online saves quite a bit... quality's decent enough and my dentist hasn't complained yet.
I've tried generic heads too, and while they're definitely cheaper, I found they wore out even quicker for me. Maybe I'm just heavy-handed or something, but after a few weeks the bristles were already looking sad and frayed. Ended up switching back to name-brand ones on sale—still pricier, but they seem sturdier in my experience. Guess it depends on your brushing style...or maybe I just got unlucky with the generics? Glad they're working out for you though!
I've actually had the opposite experience with generic heads. At first, I thought mine were wearing out fast too, but then my hygienist pointed out I was pressing way too hard when brushing. Once I eased up a bit, the generics lasted just as long as the branded ones. Maybe try being a little gentler and see if that helps? Took me a while to get used to brushing lightly, but now my gums feel better too...just a thought!
Interesting point about brushing pressure—I used to be super paranoid about brushing too hard, especially with electric brushes. My dentist mentioned something similar about easing up, but honestly, I still find myself worrying if I'm getting it right. Did you find it tricky to adjust how much pressure you use? Wondering if there's some trick or method to knowing when you're brushing gently enough...
Totally get what you're saying—I had the same anxiety when I switched to electric. My dentist suggested holding the brush with just fingertips instead of gripping it fully, which naturally reduces pressure. Felt weird at first, but it actually helped me ease up without even thinking about it. Also, some electric brushes have that built-in sensor that flashes or buzzes if you're pressing too hard—mine's a budget model but still has that feature, and it's been a lifesaver. Maybe check if yours has something similar? Either way, don't stress too much...it gets easier over time, trust me.
