Kitty's just miserable. He can't eat because his mouth hurts so much from an infected tooth. You know how bad it feels to have a toothache, so take him to the vet as soon as possible so she can diagnose and treat the problem.
If Kitty's suffering from dental problems he's likely to have symptoms in addition to loss of appetite or difficulty chewing. His breath probably smells bad, he drools and, if he's in pain, he might paw at his mouth as if to relieve the discomfort. Kitty might become lethargic or irritable. Can you blame him? He feels terrible and has no way to tell you, other than trusting you'll notice his misery.
Infected teeth often abscess. This occurs when bacteria get into the tooth's root. If you've ever had an abscessed tooth or undergone a root canal, you have a pretty good idea of what Kitty's going through. In cats, abscesses might result from fractured teeth or just ordinary tooth decay. Kitty's face might swell up and he'll be in a lot of pain. Untreated abscesses can cause infection to travel throughout Kitty's body, possibly killing the cat. Your vet can perform a root canal to save Kitty's tooth, although many owners opt for simple extraction.
In most cases, your vet will remove Kitty's infected tooth. However, if the infection results in an abscess, Kitty must receive antibiotics first to resolve the infection before any tooth extraction. If the abscess is very large, your vet might need to lance it first to relieve the pressure and drain the pus. After Kitty's tooth is removed, your vet prescribes pain medication and possibly antibiotics. Kitty should eat soft foods for several days while his mouth heals. If you notice any swelling, excessive bleeding, bad odors or pus in his mouth, call the vet.
Some feline tooth infections can be prevented by good, regular oral care. Try brushing Kitty's teeth every day to prevent tartar build-up. He might learn to like it, especially since the toothpastes are fish or chicken-flavored. According to the Cat Hospital of Chicago, tartar pushes the gums away from the roots of the teeth, loosening the teeth from their sockets and making it easier for infection to enter. Familiarize yourself with Kitty's mouth, so you notice any changes immediately. If Kitty isn't keen on tooth brushing, take him to vet every six months for dental check-ups, just as you go to your own dentist.
