Feline tooth resorption is a common dental problem that any cat can develop, but some breeds, such as Persians and Siamese, seem to be more susceptible to the condition than others. Feline tooth reabsorption occurs when your cat's immune system overreacts to the normal level of bacteria found on your cat's teeth and causes cells called odontoclasts to attack the tooth enamel, which leaves your cat with painful holes in their teeth. The condition can also damage the roots of the teeth and leave your cat susceptible to developing periodontitis. The cause of feline tooth resorption is not yet fully understood, but some researchers believe a poor diet or pre-existing gum inflammation can trigger the condition. Here's an overview of feline tooth resorption:
Symptoms
Symptoms of feline tooth resorption include drooling, localised swelling and difficulty eating, which can cause weight loss and dehydration. As this is a painful condition, your cat may show they are in pain by withdrawing from social contact, pacing the floor or pawing at their mouth. When teeth are severely damaged, cracks can appear or a tooth may fall out.
Diagnosis
Your vet can diagnose feline tooth resorption by carrying out a dental exam. This can usually be done while your cat is awake, but nervous cats may be given a sedative. If your cat has plaque or tartar on their teeth, the vet will remove this to allow them to see the full extent of damage to the surface of their teeth. Your vet will also take X-rays of your cat's teeth to determine the extent of damage to the roots.
Treatment
Treatment will depend on the severity of damage to your cat's teeth. Your vet may recommend filling small holes with dental resin, but teeth with large holes or damage to the roots will have to be extracted. Extractions are carried out under general anaesthetic, but cats can usually go home the same day as the procedure. Additionally, if your cat is dehydrated, they will require intravenous fluids and nutritional support to help them recover.
Feline tooth resorption is a progressive condition, so after your cat has been treated, your vet will arrange regular follow-up appointments to check the health of their teeth. Early detection of recurring feline tooth resorption can allow for prompt treatment and prevent unnecessary suffering.
If your cat has symptoms associated with feline tooth resorption, schedule an appointment with your veterinary dentistry provider as soon as possible.
