The most effective way to remove tartar from a cat's teeth is to combine daily care with professional treatment. In daily care, it is recommended to regularly brush your cat's teeth with a cat-specific toothpaste and toothbrush, which helps prevent tartar buildup.

For existing tartar, if it is mild, it can be improved by brushing and using dental cleaning products; if it is severe, you need to take your cat to a veterinary hospital for ultrasonic dental cleaning.
