When is it time to discard your tooth brush?

I'd say I get a new one every 3 months or so. I have 3 bathrooms and keep a toothbrush in each and since I never know which one I will be using. I keep a cap on my toothbrushes because I'm a freak like that LOL.

They say that it is best to discard it in every three months. I usually will do this. But, if the bristles are getting worned out, or the tooth brush has an foul smell then I will get rid of it.

I would say that this would be an opportune time to replace that tooth brush. My dentist told me that you should replace it every three months. I rarely change it that often. I think some of it is that tooth brush companies just want to sell more. If it ain't broke, why fix it.

I discard it as soon as its brissels gets tilted a bit . Happy Mylotting Take Care Ganesh

That would be the right time for me too! Actually, I worked for many years as a dental assistant. You should get a new toothbrush about every 3-6 months. My dentist gives us new ones at our 2xyear checkups and cleanings. I rarely buy a new one in between. If you've recently had a bad cold or flu, you may want a new one so that you will not reinfect yourself. Always purchase a soft toothbrush. Anything harder than that will cause you to damage your enamel. If your toothbrush bristles begin to looked mashed, you are brushing way too hard. It is not necessary to brush hard. You need only brush thoroughly, brushing every surface of the teeth. It is possible to brush a groove in the side of your teeth by brushing too hard. I've seen fillings placed where this has happened. This is also a major cause of tooth sensitivity. One more thing, always store your toothbrush farther than 5 feet away from your toilet. It's been proven under special lighting that when the lid is not closed, most toilets will spray about 5 feet all around your bathroom. YUCK!

Well...its good to change tooth brush every 2 months.some people use trhem till the bristles are chewed and ugly...some brushes have indicators , showing when to change the brush.i think its better to follow that.otherwise well have to pay for dentist bills.....

If I understood right you are suppose to replace a toothbrush every three months. Lol...yeppers!! It is time to get a new toothbrush when someone else uses or lick sit. Makes you wonder how many more time it has happen and you never noticed. Sounds like you need to place the toothbrush in another are ateh kitty can't get to it. Or buy or of those toothbrush covers. That just covers the part with the bristles.

Hahaha...I would definitely change my tootbrush if it's licked by a cat even if it's just 2-3 weeks old. But we can probably resolve that. Just put the toothbrush in boiled water to sterilize it a little bit. I haven't ever tried that though hahaha! According to the dentists we should change it every three months so that's what I usually to.
