Bruxism is the rather technical term for teeth grinding, a phenomenon many people experience, often unknowingly during sleep. Cats can also display this behaviour, which presents as distinctive jaw movements and sometimes audible clicking or chattering sounds, similar to those cats make when stalking prey but without the hunting focus.
Although less common than in humans, teeth grinding in cats is important to notice as it often signals an underlying issue that needs attention.
In this article, you will learn how to recognise bruxism in cats, understand its common causes, and discover practical steps to address the problem responsibly.
Bruxism in cats can be observed through the side-to-side jaw movements or the characteristic sounds your cat may make. If your cat grinds its teeth while awake, look for repetitive jaw shifts accompanied by clicking or twittering noises similar to chattering at prey but without hunting behaviour. When asleep, grinding might be subtler and intermittent, requiring careful observation to distinguish it from normal sleep movements.
Unlike humans, where teeth grinding is often linked to nervous habits or stress, in cats, bruxism usually stems from physical discomfort, most often related to dental issues. Common causes include painful teeth, gum disease, ulcers, dental fractures, or malocclusion, where the bite is misaligned causing pain or difficulty chewing.
Other less frequent causes can include digestive problems like stomatitis or gastrointestinal conditions, and rarely, anxiety or neurological disorders.
Persistent teeth grinding is a sign that your cat is experiencing pain or distress. Ignoring this symptom risks dental deterioration, increased pain, and potential complications affecting your cat's quality of life. Early diagnosis and treatment help ensure the best outcome and comfort for your feline companion.
Regular vet check-ups, good dental hygiene including professional cleanings if advised, and a stress-reduced environment are important to prevent bruxism. Responsible cat ownership means observing your pet’s behaviour closely and seeking expert advice promptly when something unusual appears.

Quick Answer: Bruxism in cats signals discomfort often from dental pain or other illnesses. A vet visit is essential for diagnosis and effective treatment.
Teeth grinding is not a stand-alone condition but a symptom that your cat might be in pain. Prompt veterinary evaluation will help identify whether an infection, injury, or another condition is responsible. Effective treatment improves your cat’s comfort and prevents further oral damage.
