What is Tooth Resorption?

This condition is commonly referred to as tooth resorption, however in the past, it has also been called a feline odontoclastic resorptive lesion (FORL) or a cervical line lesion. It may be seen in a single tooth but, generally, the condition affects multiple teeth. The bottom molars are frequently the first teeth to be reabsorbed. The issue can develop in any of a cat’s 30 teeth. Teeth can erode at varying speeds and different teeth may have different levels of deterioration. This problem is the most common oral disease found in cats, affecting up to 60 percent of domestic felines. Females and cats over five years of age are more prone to tooth resorption. 

A cat’s tooth has an upper portion (crown) and a lower portion (root). It also contains an inner canal filled with nerves, blood vessels, and lymphatic vessels. The inner portion is surrounded by a hard, bone-like substance called dentin. Sometimes, odontoclast cells will begin to mistakenly break down all parts of the tooth and reabsorb them back into the body. Often, the outside dentin near the gum line will be the first part of the tooth affected. Tooth enamel will then begin to flake off. Eventually, the entire tooth, right down to the pulp, will be destroyed. 

Symptoms of Tooth Resorption in Cats

Often, symptoms will not begin to manifest until the tooth has been destroyed down to the root. At this stage, it is generally easy to see, with the tooth appearing to be grown over by the gums. Symptoms that may occur are listed as follows:

  • Anorexia
  • Weight loss
  • Pain during eating
  • Chewing with only one side of the mouth
  • Dropping food from the mouth
  • Swallowing kibble whole
  • Drooling
  • Bad breath
  • Gingivitis (appears as a bright red section of the gums)
  • Vomiting
  • Behavioral changes

Causes of Tooth Resorption in Cats

The exact cause of this cellular response is unknown. As cases have increased greatly since the 1960s, it is thought that recent human interference has caused the problem to exist. Potential factors for tooth resorption include:

  • Excess vitamin D in cat food
  • Vaccinations
  • Neutering
  • Genetic susceptibility
  • Chemicals in city water

Diagnosis of Tooth Resorption in Cats

If visible signs of dental issues or symptoms of pain can be seen in your cat, bring it to your veterinarian for evaluation. Dental check-ups should be a part of your cat’s annual vet visit. The vet will perform a complete physical examination of the cat which will include extra focus on the oral cavity. A finger or an examination tool may be used to probe the teeth. If the cat begins to chatter it's jaw, this is often an indication of pain. The cat will then be sedated for further testing and assessment of dental issues. 

A full, intraoral X-ray of the mouth will be needed to see all teeth that are affected below the gum line, and to determine what stage of deterioration each tooth is at. Stage one includes mild cases where only the enamel has begun to erode. Stage two includes moderate instances in which parts of the cementum and dentin are being reabsorbed. In stage three tooth resorption, the tooth is deeply impacted, with all dentin down to the pulp being destroyed. Stage four classification means that extreme damage has been done to both the crown and the root of the tooth. Stage five is used to describe a tooth that has been fully reabsorbed, leaving only a hard, raised bump on the gums where the tooth used to be. X-rays can help determine if any tooth fragments remain in the gums. Urinalysis may reveal lower urine specific gravity, which can be a precursor for multiple diseases of the liver and kidneys. Stomatitis (extreme inflammation of the mouth that leads to ulcers) should be watched for, as it commonly develops secondary to tooth resorption.

Treatment of Tooth Resorption in Cats

If the resorption has been diagnosed at its first stage, treatment may not yet be necessary, although preventative extraction may be easier than fixing the problem after it progresses further. If the tooth has been determined as a stage five instance and no inflammation is present, treatment may no longer be needed as the resorption process is complete. Secondary issues that develop from tooth resorption (such as stomatitis) may need aggressive treatment.

Tooth Extraction 

This is the only effective procedure to alleviate the painful symptoms that arise from tooth resorption. A specialized surgeon may be needed for this operation. Teeth affected by this condition have a tendency to splinter into fragments during extraction, which can lead to complications. All fragments of the tooth need to be removed to prevent infection and to stop the body from producing an immune response to the broken pieces. In some cases, only the crown of the tooth needs to be removed, however, the cat must first be confirmed to have no other secondary dental diseases. 


After surgery, a course of antibiotics is often prescribed to help prevent any infections from setting in. Antibiotics made specifically to combat gram-negative anaerobic bacteria should be used after a tooth extraction. The prescription generally lasts for up to a week.

Recovery of Tooth Resorption in Cats

Your cat may need soft foods while healing from surgery. Follow all at-home care instructions closely to aid in the healing process. Administer all painkillers and antibiotics as prescribed. Monitor the extraction site for any signs of infection. You will need to bring the cat back to the veterinarian two to three weeks after surgery to ensure the procedure has gone well and that the cat is healing properly. 

It is best to maintain proper oral hygiene in your cat by brushing its teeth 2 times a week. Regularly assess your cat’s teeth and gums for any changes. Be sure to give your cat a high-quality diet that is species appropriate. This diet should be high in calcium, phosphorus, potassium and magnesium but low in vitamin D. There should be no filler foods in the ingredients. After an occurrence of tooth resorption, have your cat's dental health assessed at least twice a year. Cats who have suffered from tooth resorption often will develop the condition again in other teeth.

Redness of gums

I recently took my 3 year old cat to the vet. She noticed some redness on his gums at the base of a few of his molars and told me that it is tooth resorption. However, I haven't noticed any symptoms and he doesn't seem to be in pain. He still rubs his face against me and has had no trouble eating. Occasionally he will chatter his teeth if we get too close to the side of his mouth, but that's all I have noticed. The vet also said that it will be close to $1,200 for the surgery, does this seem reasonable? I don't really have that kind of money to spare right now, but I don't want him to be in pain. Any advice on what to do in the meantime would be extremely helpful. Thank you!

Jill, thank you for contacting us about Nimbus. I understand it can be difficult to accept that your cat might be in pain, especially when he seems to be completely normal. We can't ask our pets if things hurt. Absorptive root lesions of the teeth of cats can be a very painful condition. The chattering that you describe is a symptom of pain. I'm not sure if your veterinarian performed dental x-rays or is going to do so when Nimbus is under anesthesia, but the signs of absorptive lesions are fairly characteristic. Cats are funny sometimes about showing that they are in pain, as by nature, if an animal shows weakness, they are rejected by their group and ostracized. They don't often let you know that they are in pain until it is unbearable. If you are not sure about your veterinarians diagnosis, you would be justified seeking a second opinion, but if the absorptive lesions are there, they should be treated. The treatment often involves extraction of the teeth, and depending on where you live, $1200 can be a reasonable cost estimate for that type of therapy, yes. Again, you can always get a second opinion to be sure, but this sounds quite reasonable, sadly. Most veterinary clinics offer options like Care Credit to help with financing. I hope that everything goes well with Nimbus!

Tooth pain

My 10 yr old male cat has to undergo front fang tooth pull (which is already bloody and loose and gum covered) and dental cleaning per my vet. I'm very concerned because last month we had to put our 15 yr old cat to sleep due to multiple issues and I'm not thinking too clearly. Can you please tell me what questions or concerns I should address with the vet when my cat goes under general anesthesia for tooth pull due to resorption and dental cleaning or possible puling of other teeth? I'm concerned about his age. Thank you.

Ten years old makes Buddy a senior cat but not geriatric, there should be no issues with general anaesthesia at his age as long as he is thoroughly checked by your Veterinarian first. You should speak with your Veterinarian about Buddy’s general health and ask for a pre-anaesthesia blood test to check liver and kidney function as well as general internal health (blood counts etc…). Without examining Buddy, I cannot alert you to any other issues apart from the known dental issues; but remember that dental work in a ten year old cat is routine. Regards Dr Callum Turner DVM

My cat (6mths old) often drools and the line where his gum meets his teeth is looking a bit red. He's still eating and it doesn't seem to hurt him. Is it possible for a cat to have tooth resorption or another dental disease so early? And should I take him to the vet?

It is never too early for a cat to have dental problems and drooling is a common initial indicator that there is something not right with the mouth, you should ensure that the teeth are kept clean and should brush Foxtrot’s teeth daily especially if fed wet food. A visit to your Veterinarian would be valuable and you should also discuss neutering him too if not done already. Regards Dr Callum Turner DVM

I've noted my cat has had very bad smelling breath for a while but I ignored it and assumed it was just me being overly sensitive to his breath. Shortly after he's been having weird movements with his jaw when trying to close it after opening to meow or eat or something. Difficulty closing mouth. Yesterday he was freaking out running all around and clawing at his mouth as if he had a hair in his mouth and was trying to get it out. Later that night I further investigated to find his mouth was bleeding and a tooth was loose. He was trying to pull the tooth out and successfully accomplished it, the tooth came out and has been damaged severely at the root mostly, brownish and decayed looking. I think he has tooth resorption, but I thought I would just share, we took him to the vet and he got some anti-inflammatory for his abscess above the tooth and soon we're gonna have his teeth cleaned and x-rayed.
