Why are my dog's grey gums spreading and sore after teeth cleaning?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Female | spayed | 5 years and 2 months old | 11 lbs

My 5 year old Terrier Chihuahua mix had a professional teeth cleaning in February because I was concerned about a grey area in her gums around her front top teeth. I could tell that it was eating away her gums. The vet said that she would be fine after the teeth cleaning, but I still see it eating away her gums and the grey is spreading. Is there a treatment for this? I can tell that the area is sore by the redness around it and the way she reacts when I brush her teeth in that area.

This does indeed look uncomfortable! Pictures can be deceiving but it appears there is significant loss of bone and gum tissue above the affected teeth, with tartar and infection build up. Referral to a specialist dentist for xrays to fully assess what is going on under the gum may provide more information but it is likely that extraction of 2 or 3 teeth and repair of the gum over this area will be required in order to eliminate the infection and prevent pain
