It’s easy to forget to replace your family’s toothbrushes when there’s a million other things to do to keep a household running. However, it’s important to remember that toothbrushes can spread infection, so here are our golden rules for keeping those brushes at their best. Replace your child’s toothbrush after they are ill with a cold, flu, a tummy bug or after any mouth infections (and yours if you are ill too!). Don’t forget to keep an eye on your family’s toothbrushes and replace them when bristles start to fray, or least every 2 - 3 months. Try to keep everyone’s toothbrushes in a clean, dry, airy place so that they can dry out between uses. Ideally the toothbrush heads shouldn’t touch each other.
