Methods to deal with kittens with bad mouth:

1. Feed easily digestible food. You can feed some easily digestible food and add an appropriate amount of probiotics to speed up gastrointestinal digestion.

2. Clean your teeth regularly. If the kitten's teeth are very dirty and have a lot of tartar, you can brush the cat's teeth regularly to help it develop this habit. If the situation is serious, you can send it to a pet hospital for professional cleaning to avoid oral infection and bad breath.

3. Supplement vitamins. To match the diet reasonably, you can feed some carrots and cabbage appropriately to supplement vitamin B in the body.

4. Take antibiotics. If your cat’s stomatitis is severe, you should take your cat to a pet hospital for antibiotics.

5. Tooth extraction. It may be due to oral infection. Frequent feeding of canned or soft food to cats may lead to gingivitis. In more serious cases, it may lead to tooth nerve necrosis and the tooth must be extracted at a pet hospital.
