Cat oral care methods:
1. Teeth cleaning: It is best to have your cat's teeth cleaned at a professional veterinary clinic once a year to thoroughly clean the tartar and dirt from the cat's gums.
2. Brushing teeth: This is a daily oral care routine for cats. Pet cat owners can brush their cats' teeth regularly and also train them to brush their own teeth. Brushing 3-4 times a week can completely remove dirt from a cat's mouth and maintain its oral health and hygiene.
3. Food: In daily life, owners should try to give their cats less sticky food and choose dry food instead. Dry food won't stick to a cat's teeth like sticky food, and it also helps maintain dental health to some extent.
4. Toys: To care for your cat's oral health, you can buy some teething toys to give your cat to play with during leisure time or after meals. This will not only entertain your pet but also help maintain your cat's oral health. 
The following are some common oral health problems in cats:
1. Tartar and bad breath. Cats' teeth are prone to tartar buildup, and the process is very similar to that of humans. Tartar is formed from bacteria, saliva, and food debris, and eventually mineralizes to form tartar. Unless cleaned regularly, severe tartar buildup and bad breath will occur. Excessive tartar can also cause gingivitis.
2. Gingival ulceration and tooth breakage. Gingival ulcers are also known as "isthmic lesions" (meaning lesions occur at the point where the tooth meets the gum). Ulcers usually appear on the gum line in young kittens, eventually destroying the entire tooth structure. Once the tooth is damaged, it is prone to breakage. In addition, when the ulcer spreads to the root of the tooth, it can lead to root abscess.
3. Stomatitis. This is a rare but quite serious dental disease. Platelet hypersensitivity can trigger the cat's own immune system to attack its own gum tissue, causing tooth damage. Treatment may include steroid medications, professional dental cleanings at least every three months, and proper daily dental care, which can improve the condition. To completely cure the disease, all damaged teeth must be extracted.
4. Other dental problems. Decayed teeth can cause significant local reactions, such as pain, swelling, and severe halitosis. Tooth decay can lead to systemic reactions, such as fever, progressive weight loss, coarse hair, loss of appetite, etc. Diseased teeth can also cause many indirect negative reactions in other parts of the body, especially the heart and kidneys.
