Can Rotten Teeth Make My Dog Sick. Periodontal disease typically does not present as you describe so a visit to your vet is highly recommended. If not checked, your dog can develop periodontal disease, which destroys the gums and tissue that support his teeth.
The most common culprits are actinomycesi and streptococcus. Rotten or “bad” teeth need to be fixed. Any dog tooth can develop periodontal infection but the carnassial tooth is most likely.
