AT that age, dental disease is common. The odor and discolorations indicate an infection due to gingivitis and tartar build up. The only way to have that removed is the have her teeth cleaned at your vet. They can clean around the gums and polish teeth similar to how ours are done. They will remove any damaged or infected teeth. You will likely need antibiotics to go along with this to further treat the infection and continue with brushing to help prevent this again

    The most common cause of tooth discoloration and bad breath is severe dental disease. Other possible causes would include a systemic illness like liver or kidney failure, or even diabetes. I would recommend having your dog examined by a vet as soon as you are able to - he/she can examine his mouth and teeth to check for excessive tartar build-up and infection, and can also do blood work or other testing if needed to help determine the problem.
