Hello fellow lotter, I agree with music about replacing the toothbrush every 6 months, but you should also replace it any time you get sick, especially colds such as strep. I would assume the effectiveness would wear out if you use it longer, perhaps because of the germs and bacteria. I also heard that you can boi; your toothbrush to eliminate some of the germs, but you still need to replace it.

Boiling will help unless the bacteria is one like a Bacillus species, which form endospores when under stress and can tolerate extremely high heat (above boiling point). Endospores do take quite a while to form, though, so it depends how immediately you do it. Autoclaving units can kill them (steam and pressure at 121 degrees celsius) though. Er, not that you should autoclave your toothbrush, just that yeah- Boiling isn't always effective, so you should probably replace it every now and then (there are thermophiles that can survive high temperatures as well). Especially if you melt the plastic. xD ...Biology classes are good at making me a germaphobe.

I usually replace my toothbrush when mould starts growing on the handle. e_e; It depends. Sometimes the rigidity of the fibres are what's important when it comes to removing the dirt. In those cases, yes, the bristles usually lose rigidity over time and you should probably replace them. There are some toothbrushes that are better, yes, because of the placement of the bristles. I can't really recommend anything because I've always figured the difference is marginal at best. Don't quote me on that. ...I might get one of those toothbrushes that have a back to brush the tongue with. Supposedly it's the bacteria on the tongue that results in bad breath.

No. When you get sick, your body produces antibodies to fight against the disease- And for the most part, boiling /should/ work. Generally speaking, you should be immune for a time after you catch an illness (provided you finish your course of antibiotics, of course). It's kind of like how vaccinations work- They inject a bit of the actual bacteria into you so your body can figure out how to fight it. Also, if I remember correctly, most colds aren't actually the result of harmful bacteria/viruses- they're basically your body overreacting to a completely harmless species. So there's that! I did some research to fully answer that question, and the general consensus seems to be that a toothbrush should be replaced every 3 months; bristles tend to get worn out by then. Electrical toothbrushes can sometimes last up to 6 months. Hope that helps!

Of course it is not good to use one toothbrush for a whole year. The dentist suggests that we should change a new toothbrush every three months. And actually today some toothbrush will have a design and shows you that it is time for you to change a new toothbrush. The old toothbrush will contain more bacteria and its brush also softer and therefore it is not good for you any more. I think the famous dental brand will be better because they are professional in this field. I especially like to buy Oral-B products. I love China

Hey there youless (22432)! Yeah, I know using a toothbrush for 1 whole year is not good because the toothbrush soon gets a little destroyed and not so good anymore... But what if you have a strong toothbrush, like it's bristle don't get destroyed... Will you still be required to change it? Thanks for the answer anyway! :)

The tooth brushes come, we were using various other source and it was much better than the present day brushes. We got certain raw material and burn it and make it in a powder form and add pepper, ginger powder and clove etc alongwith and mix all of them and can be used our point finger, which was the olden method and my grand father of 85 years also having the strong teeth even now and he never our tooth paste or tooth brushes in his whole life. I think our older methods have its own values as compare with the new techniques and technologies.

hello olonam, in regards to your question about how long one should use a tooth brush, it is dependent on the brushing habit and the wear and tear of your toothbrush. if you are applying a lot of pressure while brushing, which is certainly not advisable, you would ruin the brush bristles pretty soon and hence you might need to replace your brush more frequently like in a month or so. on the other hand if you are more careful with your brushing habits, your brush will last longer. you need to keep a watch over your brush. your brush itself will tell you when do you need to replace it. normally it is advisable to replace the brushes every 3-6 months. after a certain period of time the bristles become hard and they can damage your gum tissue. more so, flared bristles do not clean the teeth properly. at that point, you need to replace it. there are two different kind of brushes, one with medium bristles and the other with soft bristles. soft one is better as it would impose no harm on either your teeth or gum tissue. hope i sorted your querry
