Why does my cat have red lines on canine teeth? Should I be worried?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | neutered | 14 lbs

I noticed my cat has one vertical thin red line on each canine tooth why is that? His other teeth and his gums look normal otherwise.

This is likely staining of the tooth from her food. There is an indentation in the tooth normally in that area that can easily collect foostuffs and staining. I wouldn't be too concerned about it and just recommend brushing his teeth daily to help prevent further staining and periodontal disease. If you notice a foul odor and/or Lio has difficulty chewing, then its best to have him examined by your vet. Also keep in mind that most cats by the age of 3 should have their teeth cleaned (Dental prophylaxis) at the vet to prevent periodontal disease and lead to excellent oral hygiene. Weekly dental maintenance can also be done through the use of greenies dental treats, dental food (i.e. Hill's T/D bites), and other over the counter products.
