Feline Tooth Resorption (FORLs) in Abyssinians
Also known as: Tooth Resorption
Feline tooth resorption — formerly called FORLs (Feline Odontoclastic Resorptive Lesions) — is the dental condition that affects most cats by middle age. Abyssinians have one of the highest documented breed prevalences. The disease destroys teeth from the inside, is genuinely painful, and is invisible without dental imaging.
Why Abyssinians are predisposed to feline tooth resorption (forls)
The cause of feline tooth resorption is incompletely understood — current evidence suggests a complex interplay of immune, dietary, and genetic factors. Abyssinians appear over-represented in the literature. Estimates suggest 60-75% of all cats over age 5 have at least one resorptive lesion, but Abyssinians may develop them earlier and have more lesions per cat.
What you'll see at home
- Often NONE visible to the owner — this is what makes it dangerous
- Subtle changes in eating: dropping food, chewing on one side
- Pawing at the mouth occasionally
- Bad breath
- Visible lesions at the gumline on careful inspection (red, eroded areas)
- Behavioral changes: less playful, more withdrawn (chronic pain)
- Reluctance to eat hard food
- Excessive drooling (advanced)
Red flags — go to an emergency vet
- ⚠ Sudden refusal to eat
- ⚠ Visible severe oral injury
- ⚠ Facial swelling
- ⚠ Fractured tooth with exposed pulp
- ⚠ Severe drooling with blood-tinged saliva
How vets diagnose feline tooth resorption (forls)
Annual oral exam at the vet, but visible inspection misses many lesions. Dental radiographs under anesthesia are the gold standard — most resorptive lesions are below the gumline. A comprehensive oral exam under anesthesia (COHAT) with full-mouth radiographs is the standard of care.
Treatment options
There is no medical treatment that stops or reverses resorption — affected teeth must be extracted. Type 1 resorption (with periodontal ligament intact): standard extraction. Type 2 resorption (no periodontal ligament, the tooth is resorbing into bone): crown amputation with root retention is an accepted alternative. Pain control during recovery is essential. Most cats eat normally within days of extraction and feel dramatically better.
Living with a Abyssinian who has feline tooth resorption (forls)
- 1 Annual oral exam by the vet plus annual dental radiographs under anesthesia
- 2 Don't assume your cat is 'fine' because they're still eating — cats hide oral pain extraordinarily well
- 3 Affected teeth must come out — there is no medical treatment
- 4 Extraction is genuinely curative for that tooth (but other teeth may develop lesions over time)
- 5 Cats live fine with extractions — they typically eat normally and play normally
- 6 Brushing helps but does not prevent resorption
- 7 Soft food during recovery; most cats transition back to normal diet quickly
Can RexVet help with this online?
RexVet is well-suited for: discussing oral health screening recommendations, post-extraction recovery care, soft food transition guidance, pain medication refills after extractions, and explaining what dental radiograph findings mean.

Prognosis — what to expect
Excellent for extracted teeth — pain resolves, eating returns to normal. The challenge is that new lesions can develop on other teeth over time, sometimes requiring repeat dental procedures. Most affected cats live normal life spans with proactive dental management.
Frequently asked questions
Frequently asked questions
How do I know if my Abyssinian has tooth resorption?
Most cases are invisible without dental radiographs under anesthesia. Even careful at-home inspection misses below-the-gumline lesions. The reliable answer: annual oral exam plus full-mouth dental radiographs under anesthesia, starting around age 4-5 in Abyssinians specifically.
Why can't tooth resorption be fixed without extracting the tooth?
There's no medical treatment that stops the resorption process. Fillings don't hold because the tooth structure continues to resorb. Root canal therapy doesn't address the resorption. The only intervention that resolves pain and prevents progression of that tooth is extraction.
Will my cat eat normally after extractions?
Yes — almost certainly. Cats are remarkably adaptive after dental work. Most cats eat the same food they ate before within days of extraction. Many cats actually eat better after extractions because the pain is gone. Soft food is recommended during the first few days of recovery.
