How many days once do you change your toothbrush?

Probly change mine about once a year or whenever I forget it somewhere on a trip I usually get a new one dont really have a time table for that guess its been about 6 months since lst time I did.

After working in a dentist office I have learned that we should only use soft toothbrushes. The medium and hard brushes wear down the enamel on our teeth. Also, when you get a cold or the flu, it is time to change it again. There is an alternative to this one though. Soak it in hydrogen peroxide once a week. I do this over night with my battery powered brush and it also cleans out the mechanism. Also, when the bristles start to flair out or wear down it is time for a new one. I like to keep several extras for visitors that forget theirs and I grab one for camping trips and overniters. I was raised to be prepared for anything!

Thank you for the best response vote. I am always happy to help people improve on their health and life style. I was raised in a dental office being around my aunt who was a dental assistant. I later worked in an office and I learned how important flossing and a good toothbrush could be. Nothing in the world like a healthy smile! That is one of the first things I notice about a man is if his teeth are clean, his breath is fresh and that he has good hygiene.

really?i didn't know that, because we change our toothbreush until it's so old and cannot function well anymore hehe! i don't think there's nothing wrong with that as long as we're brushing are teeth everyday!
