How to choose toothbrushes?

1. Young children’s gum is very tender so silicone toothbrushes are recommended; once the primary teeth have fully erupted, toothbrushes with soft nylon bristles are more appropriate.
2. Choose a toothbrush with a small sized head, around 0.8 by 2.0 cm, enough to cover two teeth.
3. Select toothbrushes with soft nylon bristles to avoid damaging teeth and gums.
4. The handle of the toothbrush shouldn’t be too thin to grip firmly.
