How often do you change your toothbrush?

I change out my toothbrush every couple of months. As you should do to help save from getting bacteria in your mouth. After a certain amount of time the bacteria collects on your toothbrush, this can cause major issues with your mouth. So be sure to keep a new one on hand. :)

I usually change my toothbrush everymonth, always making sure to keep mine a different color then everyone elses. My toothbrush has never been tattered or showed the slightest bit of being older then it needed to be. I change it every month for person hygiene reasons.

i change my toothbrush every 3 or more months. i use a hand-toothbrush and an electronic toothbrush. so i alternate between the two for morning and evening use. the main reason for this is because i find using hand version to be much faster and great in the mornings. the main purpose of brushing in the morning is to get rid of bad breath, not really getting food from your teeth. the evening is the most important because a lot of food collected up thoughout the day and plaque begins to build up.

I usually change my toothbrush at least every 3 months, but sometimes more frequently. Kind of like you, it's usually just when I notice the old one is getting worn out. I usually have a spare in closet, or if I don't have a brand new one, I will grab the one out of my travel bag. Then I know I need to purchase at least 2 next time, which I normally do anyway. And hopefully I can get a nice one that I like on sale!

Hello. Toothbrushes that I've used lasted for a few months, I think. I'm not quite sure though. I usually get ones with color indicators on the bristles and if the color's fading, I know it's time to get a new brush. Like right now, the indicator on my oral-b toothbrush is telling me to replace it... the color's almost gone!

well, i change my tooth brush every month. it is advisable not to use the same brush for more than a month.
