When to Change Your Toothbrush
When the bristles have become splayed, a toothbrush becomes less effective in removing plaque and it may also damage your gums. Even if the bristles are not splayed, they will become less elastic after long term use, making the toothbrush only half as effective. It is recommended that you change your toothbrush approximately once a month.
When to Change Your Toothbrush

When toothbrush bristles become splayed, it becomes difficult for them to make contact with the teeth. In addition, even if bristles are not splayed, they become less elastic after long term use, resulting in a reduction in the plaque removal efficiency of the toothbrush or damage to the gums.
Handling of a Toothbrush
- Wash your toothbrush thoroughly under running water after each use.
- Shake water from the toothbrush and dry well.
- Store the toothbrush upright in a well-ventilated place, with the head up.
