Contrary to popular thinking, overly energetic brushing to remove dental plaque is not a good habit for healthy teeth and gums. The aim is not to make the gums bleed, which is not normal for healthy gums. It may be the sign of gingivitis, which requires treatment. If this is the case for you, you should firstly use a suitable toothbrush, such as those from the Inava brand. Ask your dentist for advice
