Cats have 30 permanent teeth after their first teeth fall out, which usually occurs around 7-8 months of age. During this time, cats may experience gum inflammation, sometimes accompanied by bad breath and bleeding. Generally, teething doesn't require owner intervention. However, if you notice symptoms such as swollen or bleeding gums in your cat's mouth, it's advisable to take them to the vet for a checkup.
Cats with new baby teeth may bite more, drool more, scratch their faces, bang their faces against hard objects, and refuse to eat. When a cat is teething, the permanent teeth may be fully developed, but the baby teeth may still be attached. This can lead to malocclusion of the permanent teeth and oral damage, requiring timely removal. 
During teething, kittens tend to bite and drool more than usual, and may scratch their faces or bang their faces against hard objects. Providing them with toys to help them chew during this time can help prevent biting.
Cats' appetites tend to decrease during teething. During this period, you can feed them soft food and observe their teeth growth closely. Since the permanent teeth have fully developed, but the baby teeth are still attached to the mouth, they can cause damage to the permanent teeth and the oral cavity. If this is found, they should be removed promptly.
In the daily care of cats, it is also necessary to ensure oral hygiene. After eating, a lot of food residue remains in the cat's mouth, which can lead to the proliferation of bacteria over time. Owners can choose to use a pet-specific toothbrush to clean their cat's mouth.
