Toothbrushes are amongst the most used items in our bathroom, so if you want to keep your teeth and gums clean and healthy, you'll want to ensure yours stays in tip top condition.
As a general rule, dentists advise changing your toothbrush or electric toothbrush head four times a year. But, let's be honest, with busy lives who can actually remember when they last changed their toothbrush head?
"If you find you can’t remember when you last replaced your brush, it’s probably time to get a new one," says Dr Nigel Carter, chief executive of The Oral Health Foundation.
"You should aim to change your toothbrush every three months to make sure you’re getting a more effective clean.
