Let’s talk about FORLs 🐱🦷
Have you ever heard of Feline Oral/Odontoclastic Resorptive Lesions (FORLs, for short)?
This is a phenomenon where teeth start getting resorbed by the body. It can be seen in dogs, as well, but isn’t anywhere near as common, and doesn’t (always) pose the same significance aa it does in cats. It’s estimated that this condition affects over 60% of cats - and the most annoying part is: we don’t know why.
There’s currently a lot of research going into trying to identify the underlying cause(s), but so far, nothing is proven or for sure. Some of the theorized causes are:
🐱 Chronic inflammation or disease around the affected tooth/teeth
🐱 Genetics
🐱 Improper diet/nutrition
🐱 Frequent vomiting, causing increased mouth acidity
🐱 Metabolic imbalances
🐱 Underlying systemic viruses or other diseases, causing weakening of the immune system
🐱 Anatomical deformities leading to poor dental alignment, causing stress on the teeth
Thus far, no theorized cause has been able to be proven. But what we DO know is that these lesions eat away at the affected teeth, causing pulp (nerve and blood vessel) exposure - which is incredibly painful. These teeth cannot be saved, and therefore need to be extracted, with appropriate pain management plan, to prevent your pet from experiencing further pain.
These cases also go to show the importance of routine dental care for your pet, as well as the importance of both anesthesia and dental x-rays as part of that dental care plan. If these patients get no dental care, or only anesthesia-free cleanings, multiple issues occur:
🦷 X-rays aren’t able to be done, which misses potential underlying pathology that requires specific treatment
🦷 If underlying pathology is present, the cleaning will also be very painful and stressful for your pet
As you can see in the photos below, this patient’s tooth appeared overall normal on gross examination - but the x-rays reviled a different story. Fortunately, we were able to extract the affected tooth, preventing this patient from having further pain caused by that tooth.
