DATE/Toothbrush

For the patients who have the Throat Disease,changing a toothbrush every few weeks is very good for their condition.More than two months of continuous use for a toothbrush will Breeding much bacteria.Throwing away it or sterilizing it is up to you.But whatever you will do to it. people always forget when started to use it.That's the point.
There are some holes on the handle of toothbrush.With a matching stick,you can blunt some holes to make the black bottom appear.So that it can show the date when you start to use the toothbrush.There is no energy consumed in this way.So it's also a very environmental and easy way.
