How to choose a toothbrush

There are various types of toothbrushes with different shapes and configurations on the market. Here are a few key points to consider when choosing a toothbrush that best suits you:

A small brush head. A small brush head will increase the precision when you try to clean a certain spot, and help you reach narrow or tight places that are difficult for large brush heads to cover, especially the backside or your teeth. There is no universal standard for the size of a good brush head; you can pick one that best fits your personal needs.

Soft brush bristles. If a brush is too firm, it may not be able to reach the narrow gaps between teeth. In addition, a firm brush may damage your teeth and gum to cause bleeding and inflmation.

Replace your toothbrush evey 3 months. Generally, after 3 months of use, the bristle will be slowly worn out, and the effectiveness of cleaning will be significantly reduced. Moreover, bacterias will accumulate on the brush head, increasing the risks of oral diseases. For heavy users, a brush can be replaced every 1-2 months based on its shape and colour.
