Causes of mouth pain in cats
Tooth and gum disease such as tartar build up, wobbly teeth, broken teeth and gingivitis can cause a very sore mouth especially if the inside of the tooth (the sensitive part) is exposed.
Wounds in the mouth
Wounds inside the mouth can be tricky to spot. Bite injuries from prey your cat has caught (mice and rats for example) are especially common.
Foreign bodies stuck in the mouth
Something stuck in your cat’s mouth or throat such as a bone is often very painful. You may notice your cat pawing at their mouth or face.
Burns in the mouth
Cats sometimes eat things they shouldn’t. This includes hot items and chemicals which can both cause nasty burns to the inside of the mouth.
Cancerous lumps and non-cancerous lumps in the mouth can get infected and sore. When they become large they can get in the way whilst eating.
Cats get sore throats just like people. They are commonly caused by cat flu but can be caused by other bacterial or viral infections. If your cat has a sore throat you may notice them repeatedly swallowing or gagging.
Mouth ulcers are small painful white lumps on the gums that can be caused by many different diseases including kidney disease.
Broken jaws are can be caused by trauma such as being hit by a car or falling from a height.
