Guy When Did You Change Your Tooth Brush Last 3,4,5,6,7 Months Or 1year Ago

Guy when did you change your tooth brush last.

I found out that it is comon in nigeria that people use their tooth brushes for more than six months.

I don't think its because its expensive, but i think the problem is that its too cheap for us to always remember to buy it.

Like me somtimes i use my tooth brush for more than 4 months before i remember to by a new tooth brush.

Tooth brushes are very difficult to remember to buy even if one goes for shopping.

Who agrees with me here
