The toothbrush head is cracked
The toothbrush heads of electric toothbrushes are mostly made of ABS plastic material, which is suitable for most toothpastes on the market. If your toothpaste contains ketone ingredients, it will be corrosive to the brush head and cause the toothbrush head to crack during use. To solve this problem, please change your toothpaste and avoid using toothpaste containing ketone ingredients.
