My dog has tartar and black lines on his teeth. What should I do?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed | Male | unneutered | 19 lbs

Hi I’m just wondering if I should be concerned that my dog is starting to get a little bit of tartar buildup on some of his teeth and he has like a black line around some of them at the top of his teeth. Should i brush his teeth or if it’s something serious take him to the vet

Hello. This is absolutely not serious & you do not need to take Chewy to the veterinarian yet. At some time down the road, he may need to have professional teeth cleaning, but if you can start brushing his teeth, you may be able to put this off for years. Check with your nearest pet store for the appropriate products including a pet-friendly toothpaste ( never use human products ), & the various brushes & applicators you can use to keep his teeth shiny & bright. Thank you for using Petco Pet Education Center, formerly Petcoach.

    The severety of the gingivitis and the tartar warrant a dental cleaning under anesthesia. Most of the tartar here would be under the gingiva on the neck of the tooth and you would not see it unless you probed deeper underneath the gums.
    The gingivitis will subside after the tartar is removed and any rotten or damaged teeth are removed. After the teeth are pearly white again you should brush your dog's teeth regularly to delay further onset of tartar and inflammation.
