What does the number on the toothbrush mean?

The number on a toothbrush typically refers to the bristle firmness or texture, indicating whether it's soft, medium, or hard. For example, a "soft" toothbrush is usually designated with a number like 1 or 2, while a "hard" toothbrush might have a higher number. This classification helps consumers choose the right toothbrush based on their oral health needs and sensitivity. It's recommended to use a soft-bristled toothbrush to avoid damaging gums and enamel.
