1. Cat Grinding Teeth Is a Sign of Dental Disease

Cat grinding teeth while eating can be due to oral pain. We have listed several dental diseases in the list; just go through them.

1.1 Tooth Resorption

This is a quite common oral problem in adult cats breeds. In this condition cat’s teeth gum line partially or fully stops resorption. So the enamel on her teeth begins to break, and sometimes it can lead to entire teeth loss too.

Feline odontoclastic resorptive lesions (FORL) are painful and when she suffers from this medical condition cat starts to grind her teeth to soothe her pain.

1.2 Inflammation In Gums or Ulcers

One of the most highly cat gum diseases is gingivitis. The symptoms of these are blood in the gum line or swollen and reddish spots in the gums.

This occurs due to the accumulation of tartar and plaque in your feline’s teeth. If gum disease is not treated at the right time, the kitty can lose all her teeth or could also possibly get an ulcer (stomatitis).

It aches a lot, and to comfort your cat, you can give her antibiotics but remember that it won’t heal the ulcer; just soothe her pain.

1.3 Dental Abscesses

Another reason for a cat grinding teeth when eating is due to an abscess. It can appear anywhere on their skin, from their backsides to the insides of their mouths.

Not just teeth grinding, but there are also a few unpleasant symptoms also related to this. Like blood, weight loss, irritation, pus, pawing near an inflamed area.

1.4 Malformation

Just like our human teeth, alignment gets disturbed similarly; cat teeth alignment is also misshaped. This either happens because baby teeth fail to break or due to friction caused by the upper and lower cat’s jaws. This is generally due to a genetic disorder. Thus, your cat has no hand in it.

And, to soothes her dental pain caused by abnormal alignment, your cat will grind her teeth.
