Our beloved cat, especially if it's older (particularly if it's four years or older) , is more prone to developing oral health problems, such as gingivitis . Over time, plaque builds up on the teeth, hardens into tartar, and accumulates along the gum line, eventually causing inflammation. Unless treated, the animal could lose teeth and develop much more serious complications that affect its entire health.
For this reason, and considering that cats need their teeth for hunting , feeding , and grooming , we will look in detail at the symptoms and treatment of gingivitis in cats , its most common causes, the different types that exist, and how we can prevent it at home.

What are the symptoms?
To help your cat, the first thing we need to do is identify the problem , as this will make it much easier to know what to do. In the case of gingivitis, we'll see a thin red line around the base of the teeth (the gum line), which will cause increasing pain and discomfort. As a result, one of the early signs is a refusal to eat dry food , since it's hard and makes chewing more uncomfortable.
In its initial stages it may go unnoticed, but as the disease progresses, other changes will appear in the cat that should alert us that veterinary help is becoming urgent, such as these :
- Weight loss which is not explained by changes in diet or more exercise.
- Loss of appetite or irregular appetite, approaching the plate but leaving food.
- Severe bad breath (halitosis), with an unpleasant or rotten smell.
- Excess salivationwith thicker saliva and even some blood.
- Behavior changes, such as apathy, irritability, or reduced tolerance to contact.
- The mouth is not allowed to be touched He doesn't even look at us, or he complains when we try.
When the inflammation is more severe, ulcers may appear on the oral mucosa , especially at the corner or back of the mouth, along with obvious difficulty chewing and swallowing , noises while eating due to pain, and a general decline in health with lethargy and a sad appearance. In some cases, the coat may also look unkempt because the animal stops grooming due to the pain in its mouth.
What are the causes?
The causes of gingivitis can be varied and often combine. The most common is poor oral hygiene . If you don't clean your teeth, over time plaque accumulates, mineralizes, and hardens into tartar, which can lead to diseases like this. This tartar is mainly found on the outer surface of molars and premolars , where it rubs against the gum and encourages bacteria to release toxins that cause inflammation.
However, this is not the only cause. Other physical factors and general illnesses also play a role:
- Strange bodies in the gum or between the teeth (for example, small pieces of grass) that irritate the mucous membrane.
- Eruption of the permanent teeth In kittens, it can cause moderate and temporary gingivitis.
- Systemic diseases such as diabetes or kidney disease, which disrupt the body's balance and promote oral inflammation.
- History of periodontal disease or other poorly treated mouth infections.
- Poor or nonexistent oral hygiene, typical in cats that have never had dental brushing or oral checkups.
In fact, feline calicivirus and feline leukemia virus are among the most frequent causes of gingivitis in cats, and a link with feline immunodeficiency virus has also been described . These agents weaken the immune system or settle in the mouth, producing intense inflammation that can lead to feline chronic gingivostomatitis , a severe and painful condition affecting the entire oral cavity. Fortunately, preventative vaccines are available for several of these viruses.
In some cats, specific forms such as lymphoplasmacytic or eosinophilic gingivitis are diagnosed , in which the animal's own immune cells contribute to the inflammation. In these cases, the gums may appear very red, thickened, and even show areas of hyperplasia (gum that grows excessively and covers part of the tooth).
How is it treated?
The treatment for gingivitis in cats must be tailored to each patient and the specific cause . The veterinarian will first assess the animal's overall health and the degree of inflammation in the mouth, often through an examination under sedation or anesthesia to properly examine all the teeth.
If the gingivitis is mild or moderate , the veterinarian will prescribe pain relievers and antibiotics, which, along with a professional dental cleaning and the brushing you'll need to do at home, will help resolve the problem. This professional cleaning removes accumulated plaque and tartar , often using ultrasound, and usually requires general anesthesia to keep the cat still. If the cause is viral, the virus will also be treated, and medications such as specific anti-inflammatories, immune system modulators, or immunotherapy will be considered, depending on the individual case.
In cases of significant bacterial infection, broad-spectrum antibiotics are prescribed, and if the pain is intense, anti-inflammatories or corticosteroids are added to reduce inflammation. When underlying conditions such as kidney failure or diabetes are detected, it is essential to manage these conditions as well so that oral health can improve.
In more advanced cases , or when chronic gingivostomatitis is present, the affected teeth will be extracted , and even a larger number of teeth (multiple extractions) if the gums do not respond to other treatments. Although it may seem daunting, many cats experience a significant improvement in their quality of life after these extractions, as the source of constant pain disappears.
In addition to direct treatment, the veterinarian may recommend chlorhexidine rinses , softer diets during the painful phase, and products that help strengthen the immune system. Each protocol is individually designed based on the cat's response.
Prevention and home care
To prevent gingivitis in cats, it's important to brush their teeth daily using products specifically formulated for felines. This will help keep plaque at bay and allow them to use their teeth throughout their lives. If daily brushing isn't possible, try brushing at least several times a week and supplement with dental treats , toys designed for cleaning, and regular veterinary checkups.
It's also important to pay attention to diet . High-quality food, tailored to the cat and with a good composition, helps maintain overall health and, therefore, oral health. For cats with sore mouths, soft foods are preferable so they can eat without discomfort; once the inflammation is under control, the veterinarian can recommend specific options for tartar control.
Finally, creating a calm environment with stable routines and no sudden changes helps reduce stress, which also affects the immune system. A cat with good dental hygiene, regular checkups, and a well-maintained environment has a much better chance of keeping its gums healthy and avoiding the dreaded chronic gingivitis that can cause so many problems.
Taking care of your cat's mouth, being attentive to early signs like bad breath or slight gum inflammation, and going to the vet promptly when something seems wrong is a simple and very effective way to protect their overall well-being and ensure many years of comfortable life, free from pain while eating and constant discomfort in their mouth. This way, they can use their teeth throughout their life.
