My dog has a swollen face, eye knot, and bad breath. Tooth infection?

Updated On September 23rd, 2025

Pet's info: Dog | Dachshund | Female | 12 years and 6 months old | 18 lbs

My 12 year old Dachshund has a noticeable knot under her left eye. In fact, it appears that the whole left side of her face from above her eye down to her mouth is swollen. I'm thinking that she has a tooth infection. She doesn't want me to touch the area where the knot is. She walks very slowly with her head down and has already vomited once. Her breath is really bad. I'm taking her to the vet on Monday about this. She's coming off a yeast and bacterial infection in her ears that was seen to.

Yes, that is a common presentation with a molar tooth infection. The tooth will need to be extracted and they will put Tootsie in antibiotics for the infection. Blood work is usually done before anesthesia and they will scale and polish the teeth and check the rest to make sure they are healthy. Once the mouth is healed then you can start brushing her teeth or using another dental product. They may also put Tootsie on pain medication. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Tootsie.
