How often should we change our toothbrush?

According to dentists' recommendations, it should be replaced approximately every 3 months. If the bristles are worn out, brushing can lose its effectiveness. Clinical studies have shown that a new toothbrush can remove more plaque than a used one! It is also advisable to change the toothbrush after a viral or bacterial illness. In such cases, don't hesitate, get a new toothbrush!
