Feline Resorptive Lesions: What You Need to Know

Feline resorptive lesions (FRLs) are one of the most common and painful dental conditions affecting cats today. These lesions occur when the body begins to break down and reabsorb the tooth’s structure, leading to painful cavities and tooth loss if left untreated. 

What Are Feline Resorptive Lesions?

Feline resorptive lesions, also known as tooth resorption, are a condition where the enamel, dentin, and cementum of a tooth start to erode. Over time, this can expose the sensitive inner parts of the tooth, causing significant discomfort for your cat. While the exact cause of FRLs is still unknown, it’s believed to be linked to factors such as genetics, diet, and overall oral health.

Studies show that over 50% of cats will develop at least one resorptive lesion in their lifetime, and older cats are particularly susceptible. Because cats are very good at hiding pain, FRLs can be difficult to detect without regular veterinary exams. This is why routine wellness visits and dental check-ups are critical for identifying the condition early.

Symptoms of Feline Resorptive Lesions

FRLs are not always easy to spot, especially in the early stages. However, there are some telltale signs that your cat may be suffering from this painful condition. Symptoms of feline resorptive lesions include:

  • Difficulty eating: If your cat is eating more slowly or dropping food, it may be due to discomfort caused by a resorptive lesion.
  • Pawing at the mouth: Cats may paw at their mouth when they are in pain or have dental discomfort.
  • Excessive drooling: If your cat is drooling more than usual, it could be a sign of oral pain.
  • Bleeding gums: You may notice bleeding or inflamed gums, especially around the affected tooth.
  • Bad breath: Foul-smelling breath can be a sign of infection or dental disease.

If you notice any of these symptoms, it’s important to schedule a dental examination as soon as possible. Regular health screenings can help catch these issues early, preventing unnecessary pain and complications for your pet.

The Importance of Routine Dental Care

Because FRLs often start below the gum line, they can be difficult to detect without a thorough dental examination. This is why regular dental check-ups and cleanings are so important for maintaining your cat’s oral health. During these exams, your veterinarian will conduct a full oral examination and may take X-rays to look for hidden lesions.

At Monte Vista Animal Hospital, we offer comprehensive dental care services to detect any dental issues, including resorptive lesions. By catching FRLs early, we can help prevent the need for more extensive treatments down the road.

In addition to regular cleanings, it’s important to practice good oral hygiene at home. While brushing your cat’s teeth may seem challenging, there are many pet-safe products available that can help reduce plaque buildup and maintain oral health.

Treatment Options for Feline Resorptive Lesions

Once a resorptive lesion has developed, it cannot be reversed. However, several treatment options are available to alleviate pain and prevent further complications.

  1. Tooth Extraction

The most common treatment for feline resorptive lesions is tooth extraction. Removing the affected tooth eliminates the source of pain and prevents the lesion from causing further damage. Depending on the severity of the lesion, the entire tooth may need to be removed, especially if it is severely compromised.

  1. Crown Amputation

In cases where the root of the tooth is already being reabsorbed, crown amputation may be a less invasive option. This procedure involves removing the crown—the visible part of the tooth above the gum line—while leaving the root to naturally resorb. Crown amputation is often recommended when the root is already dissolving and the periodontal ligament has been lost, making full extraction unnecessary. This procedure provides relief from the pain caused by the lesion while minimizing the impact on the surrounding tissues.

  1. Pain Management

In addition to surgical options, managing your cat’s pain during and after treatment is essential. Your veterinarian may recommend medications to help alleviate discomfort and promote healing.
