This thread reminds me it's time to replace my toothbrush; it has developed a very prominent cowlick. A half a year, at most, is what it takes to get to that state.
I replace my tootbrush more because I feel like I had them a long time so I'm supposed to? They don't get that ruffled ever, maybe depends on which ones are you using. I think I buy medium ones(softness).
All my previous ones had hard bristles and went bad within 2 months. The recent one has soft and comfy bristles and has been in the same state eva since the purchase~(3 months)
I wouldn't know I have electric tooth brush and I bought a box of head replacements that will take me years to finish. ive been using it since 2015. It come in sets of 3 heads for different purposes. the toothbrush came with one that is permanent for flossing it has a latch to replace the floss string. Spoiler: Like this one
I really don't know, since you should be changing toothbrushes every 3 months. I think my toothbrush can come to that state after a few years?
I brush my teeth regularly and honestly. My toothbrush never reached that point ahahah. I usually change it every 2 month or simply when i notice that the toothbrush starts to fall apart
Like 3 months, maybe... but I don't change it as soon as it gets frayed, I only change it every year or so >.>;; Is that bad, haha...?
