How often fo you change tooth brush?

I don't change the tooth brush regularly, I will buy a new one when the current one is not very well. Sometimes it's 6 months, sometimes it's 12 months. I don't know, I change it when I'd like to.

Actually I don't change it regularly like with a schedule. My sister changes hers like every month, but as for me, I would change it when the bristles start to get uncomfortable to brush with.

My toothbrush is 24 years old and is still going strong and still looks as good as new. I had bought it in 1985 when i was working in Muscat. Oman and is of English make. It is extremely sturdy and its brushes have not degenerated a bit. I don`t see why i should change it since i have no trouble handling it. I can understand Indian made brushes going bad due to poor quality but i am happy with the one i have got since it is giving me good service and it may even probably outlive me.

I use one of those Oral B toothbrushes which have those blue indicators which when fade away means the toothbrush must be replaced. I usually change my toothbrush in 2-3 months. I think even toothbrushes have an expiry date, even though they don't mention the number of times a toothbrush can be used but generally I wouldn't use a toothbrush for more than 200 times thats about 3 months if you brush twice each day.

It's better change brush every 1 or 2 months .But, I always forget to do it because of lazy ,and , I use two kind of toothpaste a week.It's good for our tooth

When ever I buy new toothpaste I buy new tooth brush also. I use it twice. Once in the morning and before going to sleep. This is the rule of the house. Every one has to brush the teeth twice in a day and so with new toothpaste we have to get new tooth brushes also for every one. Our parents were very strict with us and so we too continued.

Friend,i used to brush twice in a day,so the damages might have occur fast to the tooth brush.So i used to change the tooth brush once in 2-3 months.
