Feline resorptive lesions (FRLs) are a prevalent yet painful dental condition affecting cats of all ages and breeds. Understanding this condition, its causes, prevention, signs, and treatment options can help you provide better oral care and improve your cat’s quality of life. Our Krichel Animal Hospital team delves into feline resorptive lesions and how to take proactive steps to ensure your whiskered friend’s dental health. 

What are feline resorptive lesions?

FRLs, also known as tooth resorption or feline odontoclastic resorptive lesions (FORLs), is a serious dental condition in cats. These lesions involve the tooth structure’s gradual destruction and breakdown, usually starting at the gumline and progressing toward the tooth root. If left untreated, the condition often requires tooth extraction. 

What causes feline resorptive lesions?

FRLs’ exact cause remains unclear. However, several factors may contribute to this condition’s development, including:

  • Genetics — Certain breeds, such as Siamese, Abyssinian, and Persian cats, are more likely to develop resorptive lesions than cats of other breeds.
  • Inflammation — Chronic mouth inflammation, often prompted by periodontal disease, may trigger the body’s immune response to break down tooth structures.
  • Diet — A high-acid diet may contribute to dental structures’ erosion, increasing a cat’s oral lesion risk.

What are resorptive lesion signs in cats?

Cats often hide dental pain signs, which can make FRL detection difficult. Ensure you periodically inspect your cat’s teeth and gums and monitor the amount they eat and whether they are exhibiting pain signs while chewing. FRL signs can present in the following ways: 

  • Drooling or excessive salivation
  • Difficulty eating, or chewing on one side of the mouth
  • Weight loss as a result of reduced food intake
  • Pawing at the mouth or face
  • Red, swollen, or bleeding gums
  • Visible holes or defects in the teeth

How are feline resorptive lesions diagnosed?

Our Krichel Animal Hospital veterinarians will examine your cat’s mouth. If lesions or dental issues are present, our team will recommend a complete dental assessment under anesthesia, including taking dental X-rays. Only with your cat under anesthesia can we understand what’s occurring in their mouth, and by taking X-rays, we can fully assess their dental structures. X-rays can reveal the extent of the damage, which may not be visible during a routine oral exam while your cat is awake.

How are resorptive lesions in cats treated?

FRL treatment depends on the condition’s severity and the damage’s extent. Our team often treats FRLs by doing the following:

  • Extraction — Extraction is often the best option for severely affected teeth to relieve pain and prevent further complications.
  • Pain management — Pain relief medications and anti-inflammatory drugs can help manage discomfort during and after treatment.

How can I prevent resorptive lesions in my cat?

Considering FRLs’ severity, you may wonder how to prevent your furry friend from developing this condition. While FRLs cannot always be prevented, such as in the case of genetic predisposition, you can reduce your cat’s risk and promote their dental health, by doing the following:

  • Regular dental exams — Our team will assess your pet’s overall well-being during their routine exams, which include dental checkups. By performing your cat’s annual or biannual dental exams, our veterinarian can detect early dental issue signs. If problems are noted, we strongly recommend that your cat undergo a more extensive exam under anesthesia. 
  • Professional dental cleanings — During your whiskered pal’s regular professional dental cleanings, we remove plaque and tartar from their teeth, reducing their oral inflammation and lesion risk. Dental disease has been linked to FRLs and can exacerbate pain and complications. Professional dental cleanings are the most effective way of preventing cats from developing dental conditions.
  • Home dental care — Brushing your cat’s teeth regularly with pet-safe toothpaste can help maintain their oral hygiene. Dental chews and diets designed to reduce plaque buildup can also be beneficial.
  • Dietary management — Feeding your cat a balanced diet low in acids and high in nutrients supports their overall dental health.

Unfortunately, FRLs are common dental problems in cats, but with proper care and attention, this condition’s impact can be minimized. Regular veterinary exams, professional dental cleanings, and diligent home dental care are effective ways to maintain your furry friend’s oral health and general well-being. If you suspect your cat has FRLs, contact our Krichel Animal Hospital team promptly for an accurate diagnosis and appropriate treatment.
