Many people don’t realise that they should change your electric toothbrush head as often as they would buy a new manual toothbrush:

– Bristles can become frayed and damage your gums when you brush your teeth.
– In addition, bacteria can build up within the brush head, particularly if it is not stored in a well-ventilated area.
“You may also choose to replace your toothbrush head sooner if you’ve been sick in an effort to not re-introduce bacteria back into your body.“
