How often should you be changing your toothbrush or the head off your electric toothbrush? Probably more often than you think!
Leading website netmums.com asked Dr Ben Atkins that very question earlier this month. The answer is about every three months. Sometimes a child’s toothbrush will need changing earlier, depending on how they use it.
The question came up in a feature on how long a number of common household items last. There were some surprising answers!
Pillows need changing every two years. By that time they may contain as much as 10% of their weight in dead skin!!
And those comfy slippers should be washed regularly and replaced every six months.
