Resorptive lesions in cats are a common yet often overlooked dental condition that can cause significant pain and discomfort. Affecting a large number of cats, these lesions can severely impact your cat’s quality of life if left untreated. At Bayview Animal Hospital, we are dedicated to providing pet owners in St. Petersburg, Florida, with the knowledge and tools to recognize and address this dental issue, ensuring your feline companion enjoys optimal health.

Understanding Resorptive Lesions

Resorptive lesions, also known scientifically as feline odontoclastic resorptive lesions (FORL) or simply tooth resorption, occur when a cat’s body begins to break down the structure of one or more teeth. Essentially, the body’s own tooth cells (odontoclasts) start to attack and erode the hard tissue of the tooth, causing painful cavities or lesions that may extend into the deeper layers of the tooth. These lesions most commonly form near the gum line but can also occur below the gum, making them difficult to detect without professional dental exams.

In more severe cases, resorptive lesions can progress to the point where the entire tooth structure is compromised, leading to tooth loss, severe pain, and secondary infections. Cats are particularly skilled at masking pain, so owners might not notice the issue until it becomes advanced.

Recognizing the Signs

Since cats often hide pain well, detecting resorptive lesions early can be challenging. However, attentive pet owners can watch for subtle signs that might indicate discomfort or dental issues. Here are some common signs that could suggest your cat is suffering from resorptive lesions:

  • Changes in eating habits: Your cat may have difficulty chewing, drop food, or avoid hard foods altogether.
  • Excessive drooling: Drooling, especially when it’s out of the ordinary for your cat, can indicate oral discomfort.
  • Pawing at the mouth: Cats may paw at their mouths if they are experiencing dental pain.
  • Reluctance to groom: Cats with dental pain often reduce their grooming habits, leading to a dull or unkempt coat.
  • Red, swollen gums: Inflammation around the gum line may be visible, especially near affected teeth.
  • Visible lesions or missing tooth structure: In advanced cases, you may be able to see damaged teeth or even missing portions of a tooth.

If you notice any of these symptoms, it’s important to schedule a veterinary visit for a dental check-up. Regular veterinary dental check-ups are key to catching resorptive lesions early and addressing them before they become more serious. 

Causes and Risk Factors

While the exact cause of resorptive lesions in cats remains unclear, several factors are believed to contribute to their development. Some of these include:

  • Genetic predisposition: Certain breeds, such as Siamese and Maine Coons, seem to be more prone to developing resorptive lesions.
  • Dietary habits: Some studies suggest that the type of diet a cat consumes may play a role in the development of dental issues.
  • Viral infections: Infections such as feline calicivirus or feline immunodeficiency virus (FIV) have been linked to a higher incidence of dental problems in cats.
  • Periodontal disease: Existing oral health problems, such as gum disease, can increase the risk of developing resorptive lesions.

Treatment Options

Treatment for resorptive lesions depends on the severity of the condition and the specific needs of your cat. At Bayview Animal Hospital, we offer a range of treatment options tailored to each case:

  • Conservative management: In the early stages of resorptive lesions, conservative treatment options may include specialized dental diets, professional cleanings, and adjustments to your cat’s diet. However, since resorptive lesions tend to be progressive, early intervention is crucial.
  • Tooth extraction: In cases where the lesion has advanced, extraction is often necessary. Removing the affected tooth can alleviate your cat’s pain and prevent further dental complications.
  • Crown amputation with gingival flap surgery: In some instances, crown amputation—removing the visible portion of the tooth while leaving the roots intact—may be a viable option. This approach is typically used when the roots are too integrated into the bone for removal.

Prevention and Home Care

While resorptive lesions cannot always be prevented, proactive dental care can significantly reduce the risk of dental problems or slow their progression. Here are some tips for maintaining your cat’s dental health:

  • Annual dental checkups: Schedule a yearly exam with your veterinarian to catch any dental issues early. Routine cleanings can also help prevent plaque buildup and reduce the risk of gum disease.
  • Regular brushing: Brushing your cat’s teeth at home with pet-safe toothpaste can help maintain their oral health. It may take some time to get your cat accustomed to the process, but regular brushing can make a big difference.
  • Dental chews and toys: Providing your cat with dental chews and toys can help reduce tartar and plaque buildup. These products are designed to encourage chewing, which is good for maintaining oral health.
  • Dental-specific diets: Your veterinarian may recommend a dental-specific diet to support your cat’s oral health. These diets are formulated to help reduce plaque buildup and maintain healthy teeth and gums.
