What Medicine for a Dog’s Inflamed Gums?

For gum inflammation, use an antibacterial oral spray such as LeKouNing. If swelling and pain are severe, add an oral pet anti-inflammatory containing metronidazole to control infection.

Brush the dog’s teeth regularly to prevent bacteria from food debris, and if there is serious tartar, have a vet perform a dental cleaning to avoid loose teeth and severe stomatitis.
