How often do you change your toothbrush?

I change my toothbrush when I have my regular checkup with my dentist, which is every 9 months. After each checkup, my dentist gives me a new toothbrush, so I just start using it that night when I brush my teeth.

hahahha.i think i din't ...ahhaha.just kiding..i change it in 2 months.

i change my toothbrush every two or three months. thats roughly how long it takes for the bristles on my toothbrush to start getting bent and worn out. i feel that when that starts to happen, the toothbrush cannot effectively be used in cleaning my teeth any longer

I change my toothbrush every two month or three month.I think using it for a long time is not good for our health.

We use our toothbrushes to clean our teeth. I brush my teeth three times a day. I usually change my toothbrush as soon as the bristles become stiff or bent and that's about 3 months. I learned that more bacteria and other airborne organisms are thriving in the toothbrush if it is not thoroughly rinsed every after use. Just be sure that tooth brush are always covered or placed in a case. It is even advisable to change your toothbrush after getting sick so to prevent bacteria in attacking you again. Also, be aware of where you place the toothbrush in your bathroom to keep it free of bacteria. Experts say that a toothbrush should be kept at least six feet away from your toilet to keep it free of airborne particles when you flush.

I do believe in changing one's toothbrush every 3 months. I think We should do as the dentist suggests and change the at the appropriate time as this may be the best for your oral health.

i do change my tooth brush at every six month.. its really need to change every regular period of time

I change my tooth brush every two month it gathers up to much bacteria so its a good idea to change it every 3 month minimum if you want healthy tips unfortonatly not everybody is aware of this fact

I change it about every six months. I don't know how much difference it make though. When I was a kid in a major city I never ever changed my brush only brushed once in a blue moon and lived in a very dirty place. I never had one cavity. But since moving to a small country town I change it every 6 months and brush twice a day I have had a couple cavities. My youngest has horrible teeth and all my kids have had cavities. They brush twice a day and get new brushes every two months. I think water, genetics could play a bigger role than the brush itself?? Don't know though, just what I observed.
