How Long Can You Use a Toothbrush


How long can you use a toothbrush? The thought really never crossed my mind until a recent visit to the dentist.

After receiving a free toothbrush all of these years from my dentist, I just assumed they liked me or instead of the free candy that you find at banks, I thought dentists just gave out toothbrushes. So being accustomed to getting a free toothbrush, I never wondered how long can you use a toothbrush.

Well, after asking a dentist directly, it turns out they are being nice by supplying patients with toothbrushes however; there are times when you should replace it on your own.

So how long can you use a toothbrush anyway? Dr. David Newman, DDS; Newman Family Dental, says that you should replace your toothbrush every 6 month. However depending on the pressure that you use while brushing, you may have to replace your toothbrush after 3 months of use.

This is because the more that you use your toothbrush, the more that its bristles began to wear down and fray. As toothbrush bristles age, they begin to bend and curl downward.

When this happens, the bristles don’t clean the teeth properly and plaque starts to build up on your teeth quickly, regardless to how frequent you brush your teeth.

Your mouth is filled with bacteria and scientists have identified much of the same bacteria on your toothbrush. They have even found the e-coli bacteria on toothbrushes.

If you have recently been sick with anything other than a common sniffle, dentists recommend that you replace your toothbrush immediately. Although you may rinse your toothbrush thoroughly bacteria can still remain deep in the bristles of the toothbrush.

An old toothbrush can cause many health related problems that people are not aware of especially in people that have low immune systems.

Dentists also state that you should never keep your toothbrush in one of those decorative holders alongside other people’s toothbrushes. If the toothbrushes touch, as most do, bacteria can easily be transferred between the toothbrushes.

Storing your toothbrush in a bathroom where there is a toilet is also a no go. Bacteria from the toilet is released into the air in the form of a mist, every time that you flush the toilet.

You can’t see it with the naked eye but it is like holding a squirt bottle above your head that is on the mist setting and squeezing the trigger each time that you flush the toilet.

I hope that this article has helped you to better understand the importance of replacing your toothbrush. I wrote this article but I can admit that I too have learned something new and now I’m off to the store to buy 10 new toothbrushes.
