Our new pet toothbrush contains oat extract and xylitol. It can perfectly fit the shape of pet teeth, effectively remove hard to reach debris and plaque in the gaps between teeth, ensuring that every corner of the mouth can be thoroughly cleaned and maintaining the oral health of pets. Its usage is simple: open the pen cap, rotate the pen tip clockwise until a small amount of liquid overflows from the brush head, stop rotating, and apply it to the surface of the pet's teeth for cleaning. And specially designed for pets, the gentle touch avoids damaging delicate gums and teeth, making the cleaning process safe and comfortable, even the most sensitive mouth can be used.
